[0016] Bowden cable transmits mechanical force over the distance between two points. Bowden cable can be used with an engine or an apparatus including an engine. Examples can be vehicle engines (such as outboard boats, lawn mowers or golf carts), or handheld equipment such as chain saws, weed trimmers or blowers, and other devices. These devices may include a handle or other user input portion, wherein the user operates the device by applying motion to the input portion connected to the Bowden cable. Bowden cable can be used to transmit force between the input portion and the engine. Bowden cable allows an inner portion (e.g., in a wrong cable or wire) to move within an outer portion (e.g., an outer tube), which protects the inner portion and allows the inner portion to transmit force without the need for a joint or pulley between the user input portion and the engine.

[0017] However, some engines can use electronic communication to circumvent the transmission force of the Bowden cable type. Electronic communication can also allow the engine to receive throttle settings and apply throttle settings internally without using a Bowden cable. Electronic communication can include radio frequency-based wireless communication, station line wireless communication, or communication through wired conductors. However, a device equipped with a Bowden cable may be incompatible with such engines utilizing electronic communication. The following embodiments include examples in which a throttle control relay system receives user input at a Bowden cable device and converts the user input into a control signal compatible with all types of engines.

[0018] Figure 1A A remote throttle control relay 10 is shown. Figure 1B An exploded view of the remote throttle control relay and housing of FIG1 is shown. The remote throttle control relay 10 may be an actuator mounted on the engine that receives input from a Bowden wire throttle cable and relays the position via a throttle position sensor to an electronic throttle body. This intermediate actuator allows certain types of engines to be attached to certain devices with a throttle cable without any additional modifications that may otherwise be necessary to connect the electronic throttle body to the throttle cable.

[0019] The remote throttle control relay 10 includes a harness side portion 11 of the housing, a lever side portion 13 of the housing, and a lever 15. A seal 17 (e.g., an O-ring), a bushing 19, a sensor 21, and a shaft 23 are provided inside the housing. One or more screws 22 or other fastener types can couple the components of the throttle control relay 10 together and / or to the engine. As shown, a pair of screws 22 extend through the harness side portion 11 and the lever side portion 13 to surround the remote control throttle relay 10. Additional, different, or fewer components may be included.

[0020] The throttle lever 15 can be connected to the input lever 12 via an input 20 (e.g., a Bowden cable or a push-pull rod). The input 20 can include an inner portion that moves within and relative to the outer portion. The input 20 can include a metal wire 20b that slides within a plastic sheath 20a. The input 20 can include a rigid rod. The input 20 can include another type of transmission system such as a gear train or a pulley system. The input lever 12 can be a button or a handle that an operator or user of the engine moves to adjust the throttle of the engine. The input line 20 enables the adjustments made by the operator to be reflected in the position of the throttle lever 15. Another screw 22 can connect the throttle lever 15 to the lever side portion 13.

[0021] The throttle lever position sensor 21 can be a magnetic sensor. The magnetic sensor can include an element in a measurement circuit that changes resistance, inductance, or another electrical characteristic based on position. The throttle lever position sensor 21 can be configured for a predetermined angular range. For example, the throttle lever position sensor 21 can use a 75-degree rotation from the engine's throttle plate fully closed to the throttle plate fully open. For the throttle plate rotation, the throttle lever 15 can operate with a linear travel distance equal to 75 degrees. For the same rotation range, a longer throttle lever 15 can correspond to more linear travel.

[0022] The throttle lever position sensor 21 may be a potentiometer configured to cause a variable resistance between an input to the throttle lever position sensor 21 and an output of the throttle lever position sensor 21. The rotational position of the potentiometer causes the resistance to change. The resulting voltage or other electrical component may be measured through a voltage divider or another variable resistance circuit, which is converted to a physical position of the throttle lever position sensor 21.

[0023] The throttle lever position sensor 21 can be a linear variable differential transformer. The linear variable differential transformer can be an alternating current (AC) transformer including three coils wound on a hollow tube. One of the coils is a primary winding for transmission, and the other two coils are secondary windings connected in series. When the throttle lever position sensor 21 moves, the secondary coil overlaps with the primary coil to varying degrees. Then, when the throttle lever position sensor 21 moves, the output of the linear variable differential transformer can change in electrical components (e.g., voltage, power, inductance). A conversion device can be used to convert the rotational motion of the throttle lever position sensor 21 into the linear motion of the linear variable differential transformer. Through a measuring circuit, the resulting electrical component can be measured, and the resulting electrical component is converted into the physical position of the throttle lever position sensor 21.

[0024] The output from the throttle lever position sensor 21 may be a variable voltage signal that indicates the position of the throttle lever 15 and indirectly the direction and degree of the user input. The throttle lever position sensor 21 may include an internal microprocessor, and the output voltage per angle increment of the throttle lever 15 may be programmable to enable smooth transitions or step-wise changes in the output voltage. Obtaining the desired speed / voltage may be programmed into the throttle lever position sensor 21. Table 1 is an example set of pairs of output voltages associated with engine speed that may be used.

[0025]

[0026]

[0027] Figure 2A and Figure 2B An example engine 100 including a remote throttle control relay 10 is shown. The engine 100 may be a vertical axis engine. The remote throttle control relay 10 may be mounted on top of an electronic control unit (ECU) 101 of the engine 100. For example, one or more screws may connect the remote control relay 10 to the housing of the ECU 101.

[0028] The output from the throttle lever position sensor 21 is provided to the ECU 101 for controlling the throttle (e.g., throttle plate). In one example, one or more wires connect the throttle lever position sensor 21 to the ECU 101. In another example, a controller connected to the throttle lever position sensor 21 generates a wireless signal to the ECU 101.

[0029] The throttle plate can be moved by a stepper motor or other actuator that operates in response to the voltage level in the variable voltage signal. The throttle adjusts the flow of air and / or fuel to the engine 100. The throttle can control the flow of air flowing into the intake manifold or the flow of a mixture of air and fuel flowing into the intake manifold. The throttle may include a butterfly valve or a throttle plate that rotates to regulate the air. The valve or plate may be controlled by a mechanical connection with the throttle assembly 30. The throttle may extend to the wall of the intake manifold. That is, the radius of the throttle disc may be slightly smaller than the radius of the intake manifold. Alternatively, the throttle may be spaced apart from the intake manifold so that some air can always flow around the throttle.

[0030] The engine 100 may be any type of engine in which the combustion of a fuel (e.g., a gaseous fuel or a liquid fuel) and an oxidant (e.g., air) in a chamber applies a force to a drive component (e.g., a piston, a turbine, or another component) of the engine 100. The drive component rotates to turn a drive shaft.

[0031] The engine 100 may be a four-stroke cycle engine, which means that four piston strokes constitute one cycle. The compression cycle of the engine 100 includes an intake stroke, a compression stroke, a power stroke, and an exhaust stroke. During the intake stroke, the piston moves from the top of the cylinder to the bottom of the cylinder. The fuel and air mixture is forced into the cylinder by pressure. Next, during the compression stroke, the piston moves back to the top of the cylinder, compressing the fuel and air mixture into the cylinder head. The fuel is sprayed and / or atomized into the cylinder through the nozzle of the fuel injector. Next, during the power stroke, the compressed fuel and air mixture is ignited by a spark plug or a heat source. The piston is pushed back down to the bottom of the cylinder by pressure. Finally, during the exhaust stroke, the piston returns to the top of the cylinder to discharge the spent or burned fuel and air mixture through the exhaust valve. In a spark ignition engine, the air and fuel mixture is forced into the cylinder during the intake period, and after the piston compresses the mixture, the spark ignites the mixture. Combustion from the spark causes the gases to expand, which pushes the piston during the power stroke.

[0032] The liquid fuel may be gasoline, diesel, ethanol or another example. The gaseous fuel may be liquefied petroleum gas (LPG), hydrogen, natural gas, biogas or another gas. LPG may be a mixture of butane, propane or hydrocarbon gases or a mixture mainly including butane, propane or hydrocarbon gases. Hydrogen may include hydrogen mixed with air or oxygen. When delivered to the engine 100, the hydrogen may be mixed with another fuel. Natural gas (e.g., compressed natural gas (CNG)) may be a hydrocarbon gas mixture. Biogas may be a gas produced by the decomposition of organic materials.

[0033] The engine 100 may be used in a variety of devices including, but not limited to, a chain saw, a lawn mower, a weed trimmer, an all-terrain vehicle, a wood splitter, a pressure washer, a garden tiller, a snow blower, a lawn mower, a golf cart, or other vehicles or devices.

[0034] The engine 100 may be liquid cooled or air cooled. In a liquid cooled engine, a radiator contains a cooling fluid that is pumped through the radiator. In an air cooled engine, the engine is cooled through one or more air paths of the engine. In some examples, the engine cylinders are cast with one or more fins having a large surface area. As air blows through the cylinders and fins, heat is removed from the engine.

[0035] Other systems in the engine 100 may include a fuel tank, a fuel line, a retractable starter, an air cleaning system, an exhaust system, a muffler, a control section, a governor system, and a lubrication system. The retractable starter may include a recoiler and a pull handle for starting the engine 100. The air cleaning system may include one or more filters for removing particles from the intake air of the engine 100. The muffler may receive exhaust from the exhaust system, which includes combustion byproducts in the engine 100. The muffler may reduce noise from the engine 100 and / or remove byproducts from the air. The governor system may adjust the throttle of the engine 100. The lubrication system may provide oil or another lubricant to the engine 100.

[0036] Figure 3A and Figure 3B An example remote throttle control relay 10 is shown having a wiring harness connector 31 . Figure 3A An example cable is shown including a sheath 20a and inner conductors 20b. Bolts 51 may secure the cable to a mounting frame 52 coupled to the engine.

[0037] The throttle lever position sensor 21 may include a calibration input 26 configured to reset a reference position of the sensor. The calibration input 26 may be a button, a slider, or a clip that adjusts the relative position between the throttle lever 15 and the throttle lever position sensor 21. In one example, a user may move the throttle 15 to be fully open or fully closed, and the user may press the calibration input 26 to reset the calibration of the throttle lever position sensor 21 and / or output its value in response to the calibration.

[0038] Figure 4An example wiring diagram of a remote throttle control relay 10 is shown. In one example, the rotational position sensor 21 is connected to 3 wires; a 5 volt input (constant voltage input) (e.g., connector AA), a 0-5 volt output (variable voltage output) (e.g., connector O), and a ground. The constant voltage input can be connected to a power supply for another engine device or engine function. For example, the constant voltage input can be connected to a power supply pin of another sensor (e.g., a temperature and manifold pressure sensor or a throttle position sensor). The ground can be connected to a chassis or a ground pin for another device (e.g., a battery ground). The variable voltage output of the rotational position sensor 21 can be connected to an input pin for a throttle control (e.g., a speed selection input) of the engine. The variable voltage output varies between a first value and a second value. The variable voltage output can be proportional to the rotational motion or linear distance change of the throttle lever 15. No additional circuit boards or modifications to the wiring of the ECU or electronic throttle body are required.

[0039] Figure 5A and Figure 5B An example connector for a wiring harness 31 is shown. A male connector body 43 surrounds a moisture seal member 42, a wire pin connector 41 (e.g., a terminal), and a snap-in wire and seal retainer 45. The terminal 41 has a protrusion at the top to allow a snap feature in the body to prevent the terminal and wire from being pulled out. Each wire with a crimped terminal is inserted through the retainer and sealed into the connector body until the retaining finger snaps into place. The terminal 41 is connected to the ECU 101 of the engine 100.

[0040] Figure 6 The connection of the connector and wiring harness 50 to the electronic control unit 101 of the engine 100 is shown. Figure 4 In a specific example embodiment, the remote throttle control relay 10 may include connections to various components of the engine and output pins in a pin array W and a pin array X. The components of the engine may include a stator A, a rectifier-regulator B, a fuse D connected to a starter motor R through a connection C, a battery F connected to the starter motor R through a connection E, and a fuel pump module J connected to the pin array X and the pin array Y through a connection H and a connection I. The ground G is connected to the various components.

[0041] An eight-terminal connector N also connected to the pin array W may include a connector K, a connector L, and a connector O. As shown, connector O corresponds to the variable voltage output of the remote throttle control relay 10. An additional connector P may be coupled to the diagnostic connector AL.

[0042] The starter motor R can be connected to the rectifier-regulator B via a fuse D and to the connector N and to the connector N via a connection Q. A connection U connects the starter motor R to the diagnostic connector AL. An oil pressure switch T is connected to the connector N via a connection S. A fuse V connects the battery B to the pin array X. Another fuse V can connect the connector N to the pin array X.

[0043] Additional components located in the engine and corresponding to wiring pins in the wiring harness may include a first fuel injector AC, a second fuel injector AD, a first ignition coil AE, a second ignition coil AF, a crankshaft position sensor AG, an oxygen sensor AH, an electronic throttle control (ETC) AI, a temperature manifold absolute pressure (TMAP) sensor AJ, and an engine temperature sensor AK. In one example, the TMAP sensor and / or the ETC AI include a constant 5 volt signal, as indicated by connector AA.

[0044] Figure 7 An example embodiment of a control system 301 for a remote throttle control relay 10 is shown. The control system 301 may include a processor 300, a memory 352, and a communication interface 353 for docking with a device or to the Internet and / or other network 346. In addition to the communication interface 353, a sensor interface may be configured to receive data from the sensor 21. Additional sensor data may be received from the first fuel injector AC, the second fuel injector AD, the first ignition coil AE, the second ignition coil AF, the crankshaft position sensor AG, the oxygen sensor AH, the ETC AI, the TMAP sensor AJ, and the engine temperature sensor AK. Additional, different, or fewer components may be included.

[0045] The components of the control system 301 can communicate using bus 348. The control system 301 can be connected to a workstation or another external device (e.g., a control panel) and / or a database for receiving user input, system characteristics, and any values ​​described herein. Optionally, the control system 301 may include an input device 355 and / or a sensing circuit that communicates with any sensor. The sensing circuit receives measurements from the sensors as described above. The input device 355 may include a touch screen, a keyboard, a microphone for voice input, a camera for gesture input, and / or a holographic interface that is connected to or integrated with the control system 301 or with the control system 301.

[0046] Optionally, the control system 301 may include a drive unit 340 for receiving and reading a non-transitory computer medium 341 having instructions 342. Additional, different or fewer components may be included. The processor 300 is configured to execute instructions 342 stored in a memory 352 for executing the algorithms described herein. A display 350 may be supported by the control system 301. The display 350 may be combined with a user input device 355.

[0047] Fig. 9 An example flow chart of a process for operating a throttle assembly is shown. Additional, different, or fewer actions may be included.

[0048] In action S101, a user input is received at a local throttle lever. The local throttle lever may be a hand-held lever that is squeezed. The local throttle lever may be a twist handle that rotates around a handlebar or another steering mechanism. The local throttle lever may be a monkey grip. The local throttle lever may be electronic, including one or more buttons or alphanumeric inputs.

[0049] In action S103, the user input is converted to the remote throttle lever using a mechanical conversion device such as a cable or a rod. The mechanical conversion device can transfer the force at the user input to another location (eg, local to the engine).

[0050] In action S105, sensor 21 detects the position of the remote throttle lever by processor 300 and / or control system 301. Sensor 21 can be a magnetic sensor in a measurement circuit. The magnetic sensor can change resistance, inductance, or another electrical parameter in response to the position of the remote throttle lever. When a predetermined voltage or current is provided across or through the magnetic sensor, processor 300 and / or control system 301 measures the modified electrical parameter. The magnetic sensor can be a coil, and processor 300 and / or control system 301 can detect changes in magnetic flux density through the coil. The magnetic sensor can be a reed switch, which includes two or more magnetic components (e.g., in a glass tube) that are approached by the movement of the remote throttle lever. At a predetermined proximity, the magnetic components touch, which is detected by the processor 300 and / or control system 301 through the measurement circuit.

[0051] In one example, the sensor 21 is a potentiometer. The processor 300 and / or the control system 301 measures the resistance of the potentiometer through a measuring circuit. The resistance indicates the position of the remote control lever. The sensor may include an inductive sensor including at least one coil or transformer. The processor 300 and / or the control system 301 measures the inductance of the inductive sensor through a measuring circuit. The inductance indicates the position of the remote control lever.

[0052] Sensor 21 can be an optical or line of sight sensor. Sensor 21 can emit a light beam or laser that is reflected to determine the position of the remote control lever. In one example, processor 300 and / or control system 301 measures the flight time of the reflected light to calculate the position of the remote control lever. In one example, the remote control lever includes a mark detected by the optical sensor and analyzed by processor 300 and / or control system 301. For example, the optical sensor can be aligned at a specific position (e.g., a window), and the remote control lever moves through the specific position. Markers, lines of different thicknesses, circles of different radii, or other examples are included in the pattern on the remote control lever. Depending on the position of the remote control lever, the optical sensor detects different marks, and processor 300 and / or control system 301 determines the position with reference to the marks.

[0053] In action S107, an output signal is generated indicating the position of the remote throttle lever. In action S109, a throttle of the engine is controlled based on the output signal. For example, the throttle plate may be opened or closed by a predetermined amount or a predetermined position based on the output signal. The processor 300 and / or the control system 301 may generate a command to move the throttle plate. The command may include a stepper motor position, a stepper motor increment, or an angle value.

[0054] Fig. 9 An example flow chart of a process for manufacturing a throttle assembly is shown. Additional, different, or fewer actions may be included.

[0055] At action S201, a first electrical connector is connected from the throttle control relay 10 to the engine.

The constant voltage source may be 5 volts, 12 volts, or another value. The constant voltage source may be provided by a battery or a rectifier. The constant voltage source may be associated with a starter or ignition device for the engine. The constant voltage source may be provided to the first electrical connector via a jumper or a bridge, connected to a predetermined pin or wire of an electronic throttle controller or a sensor such as a TMAP sensor.

[0056] At action S203, a second electrical connection is connected from the throttle control relay 10 to the engine. The second electrical connection may include a wire or pin connector of a wiring harness. The second electrical connection may be a variable voltage input provided to the engine (eg, to an electronic throttle controller).

[0057] At action S205, the second electrical connection is connected to a position sensor for user input. Any of the example position sensors described herein may be used.

[0058] At action S207, the throttle control relay 10 is fastened to the engine. The throttle control relay 10 may be fastened using one or more screws, bolts, or other fasteners.
