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 apparatus and method for the creation, placement and control of an area of electrical ionization within an internal combustion engine combustion chamber. This area of electrical ionization is positioned so that all of the fuel being injected into the combustion chamber must pass next to or through the area of electrical ionization to ensure that combustion has been initiated for all of the fuel as it is injected. This area of electrical ionization can be kept on as long as it is necessary to insure that the all of the fuel that is injected into the combustion chamber can be completely combusted. An engine equipped with this electrical ionization device has its fuel economy enhanced by timely, controlled, and complete combustion of all of the fuel injected into its combustion chamber. Furthermore, the pollutant emissions of both oxides of nitrogen and unburned hydrocarbons are reduced dramatically. Further, cold starting capability of this engine is greatly enhanced by a major reduction in the time necessary for the engine to warm up and a major reduction of pollutants created by the engine during the warm-up period. Additionally, this method of combustion also allows the engine to operate at a higher speed (rpm) allowing an increase in peak power output.

The present invention provides a gas turbine rotor having a first axial compression stage for compressing air in a first direction and a second axial compression stage for compressing the air in a second direction, the second direction being generally opposite the first direction.

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.

The invention relates to a processing system aiming at the dilution problem of engine oil. The processing system comprises a heat exchanger, the engine oil, an insulating tube, an oil pump, an oil pressure sensor, an oil temperature sensor, an oil way switch and a vent pipe used for recycling fuel. When the engine is in operation, if oil pressure valve is below limiting value, an exhaust manifold is used to heat the insulating tube. The engine oil of a control pipeline and the fuel in an oil sump are used to exchange heat to lead bulk temperature to the boiling point of the fuel, thus separating the fuel from lubricant. The separated fuel goes through ventilation system and enters burning system again.

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 working machine has an engine, a working part driven by motive power from the engine, and a control part for controlling the engine.

To provide a spark plug with improved heat resistance and an internal combustion engine in which that spark plug is mounted where there is good conduction of the heat near the opening on the combustion chamber side of the mounting hole for the spark plug provided in the engine and the effects of thermal stress occurring near that opening are mitigated. A cylindrical part without threads formed thereon is provided on the leading end side of a metal housing of a spark plug and the thermal stress applied to a mounting hole is mitigated by avoiding close contact with the mounting hole of an engine head. Furthermore, the spark plug has a mounting structure in which the leading end surface of the cylindrical part is disposed 1.55 mm or more to the base end side in a mounting hole in the direction of the axial line O with respect to the wall surface inside the combustion chamber. By this means, the metal housing does not easily take up the heat that accompanies combustion of the air-fuel mixture inside the combustion chamber at the cylindrical, part so there may be good heat conduction.

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.
