Methods for indicating whether a crankcase of an engine is breeched are provided. One example method comprises restricting a communication of the crankcase with atmosphere, acting to increase or decrease a crankcase pressure, and indicating whether the crankcase is breeched based on the crankcase pressure. Another example method comprises sensing a crankcase pressure component, and indicating whether the crankcase is breeched based on the crankcase pressure component, the crankcase communicating with atmosphere via a conduit, a restrictedness of the conduit responsive to one or more of a crankcase pressure and a signal from an electronic control unit of the motor vehicle. Still other examples provide more particular methods for indicating whether the crankcase is breeched, and example configurations that enable the various methods.

An engine control system (10) operates off a microprocessor of an engine control module, ECM (62), which will automatically start a combustion engine (12) upon any one of a series of enabler signals (68, 67, 70) indicative of low battery voltage, low cab temperature and / or low engine temperature. The system (10) also includes safety measures which will override the automatic starting of the engine. For instance, the vehicle will not automatically start if a vehicle speed is detected, if the parking brake is not set, if the ignition key (50) is not in the “on” position, or if the hood (56) is open. Moreover, the system (10) is configured not to start if the fuel level is low, thus preventing an unintended depletion of fuel which could strand the vehicle and operator.

A method for controlling the speed of an engine driving a generator supplying electrical current to a load includes the steps of monitoring the current, increasing the speed when the current increases and decreasing the speed when the current decreases. The governor apparatus used to carry out the method includes a microcontroller having a current and frequency look-up table embedded in it. For some part of the monitoring step, the engine runs at a first speed, e.g., idle speed, or some moderate speed above idle speed. The increasing step includes detecting an increase in the current to a value, determining from the look-up table the frequency corresponding to the value and increasing the speed of the engine until the frequency of the current is the frequency corresponding to the value. To state it in other words, the new method and apparatus control the engine at a modest speed when the generator is unloaded or lightly loaded and increases engine speed and current frequency with increases in generator load.

An auxiliary power device for attachment to an existing refrigeration unit of a refrigerated trailer to serve as a power source to a truck cab, thereby allow operation of electrical devices in said cab without idling of the truck's engine. The auxiliary power device comprises a housing attached beneath the existing refrigeration unit, an electric generator enclosed within the housing, and a pulley assembly mounted in the housing and connected by drive shaft to the generator. The pulley assembly is connected via drive belt to the diesel motor in the existing refrigeration unit. When the generator is activated a first relay governs the speed of the diesel motor in the refrigeration unit, which turns the generator to generate power, and a second relay prevents drainage of the refrigeration unit battery. The power from the generator is routed through a breaker panel mounted in the cab of the truck for distributing and regulating power from the battery and / or generator into the truck cab. Thus, the driver can power electric devices in the cab from the auxiliary power generation device without idling the truck's main engine, thereby reducing fuel consumption, harmful emissions, and prolonging engine life.

This design is for a motor vehicle drivetrain utilizing flywheel rotation to store energy during the vehicle trip, either storing energy when accellerated, or releasing energy when slowed depending on the vehicle power requirements. At the same time the engine is allowed to operate at a constant RPM and throttle setting, determined by the best thermal efficiency of the engine selected (the engine itself is not a part of this patent application). The continously variable speeds of the vehicle are made possible by the design's transmissions using sintered metal construction, a cogged drive belt, and a pattern of surface protrusions meshing with the cogged drive belt. The flywheels are slightly offset to allow simple gear meshing, and are counter-rotating to cancel out flywheel precession and torque reaction when providing power to the drive wheels. This eliminates any adverse effect on the vehicle's behavior that might otherwise result such as causing the vehicle to spin on slippery surfaces.

A one-step starting carburetor includes a body, and a pulse generator and an oil pumping unit which are connected with the body. The oil pumping unit can produce an oil pumping function to pump fuel from an oiler to the carburetor when a flywheel of an engine is revolving. When the carburetor is operating, it only needs to pull a starting line and does not need to extrude an oil pumping ball to pump the fuel for the carburetor or to close a choke valve. After hearing a voice like ‘poop-poop’, it does not need to half open the choke valve to warm the engine or to open the choke valve after warming the engine. Thus the operation of the carburetor is simple for users' convenience.
