摘要： A rotary piston engine comprises a housing having a trochoidal peripheral wall and side walls on both sides thereof, a rotor adapted to perform a planetary rotary motion along the inner surface of the peripheral wall, and intake and exhaust ports formed in the housing. The engine performs intake, compression, combustion and exhaust strokes of a working fluid in accordance with the planetary rotary motion of the rotor. An air injection port is formed in the peripheral wall of the housing between the exhaust port and a portion of the minor axis of the trochoidal curve, being adapted to communicate with the intake chamber formed between the peripheral wall and the rotor. Through the injection port, air and fuel are supplied into the housing to prevent recirculation of exhaust gas into the intake chamber of the engine, to stratify an air-fuel mixture of a richness appropriate for spark ignition and an air alone so as to facilitate the combustion of a lean air-fuel mixture as a whole, and to reduce harmful exhaust gases, particularly, hydrocarbon (HC) and carbon monoxide (CO) by the engine operation with the relatively lean air-fuel mixture.

摘要： An ignition system for rotary piston engines includes a glow plug in addition to the normal leading spark plug and trailing spark plug. The glow plug is mounted in the housing of the engine on the leading side with respect to the trochoidal minor axis in the direction of the rotor rotation and performs continuous ignition of the mixture during low speed and load operation of the engine. Thus, during the low speed and load operation the glow plug performs ignition in place of the leading spark plug whereas during other engine operating conditions the leading spark plug and the trailing spark plug perform the ignition of the mixture.

摘要： An ignition device for a rotary piston engine includes a glow plug which is mounted at an ignition port formed in an engine housing to communicate with a combustion and operation chamber and which, when electrically powered, is heated to red hot to ignite an air-fuel mixture in the combustion and operation chamber. The glow plug ignites the air-fuel mixture through a communicating port which is formed to face the combustion and operation chamber and which has a smaller aperture area than the cross-section area of the ignition port.

摘要： The temperature of a glow plug mounted on an epitorocoidal engine housing on a leading side of the torocoid minor axis of a rotary piston engine in the direction of the rotor rotation is sensed. When the sensed temperature exceeds a predetermined temperature within a temperature range which allows the ignition of air-fuel mixture, power to the glow plug is stopped whereby the life of the glow plug is extended and the power consumption is saved.

摘要： A fuel injection apparatus which, when raising fuel of a low viscosity and a low lubricating ability such as gasoline or methanol to a high pressure by a fuel injection pump and injecting it into a combustion chamber of an internal combustion engine etc., prevents the lubricating oil for the fuel injection pump from being diluted by this fuel by pressurizing a separate working oil with a viscosity and lubricating ability higher than the fuel by the fuel injection pump and raising the pressure of the fuel by a diaphragm apparatus by the pressure of the high pressure working oil and thereby supplies the same to the fuel injector.

摘要： An internal combustion engine has an evaporated fuel purge system for directly feeding evaporated fuel of a fuel tank into an intake pipe of the engine during the engine is running. This system comprises a purge control valve for opening or closing a flow line which connects an upper space of the fuel tank with the intake pipe, a controller for controlling the operation of the valve, a throttle section formed in series with the purge control valve, and pressure and temperature sensors which are located on the upstream side of the throttle section for detecting a pressure and a temperature of the evaporated fuel. When a value detected by the pressure sensor exceeds a predetermined value of pressure for providing a critical pressure ratio at which a flow rate of the evaporated fuel at the throttle section substantially equals to a sonic velocity, the controller opens the purge control valve to cause a purged flow of the evaporated fuel whose flow rate is constant. Simultaneously, the controller calculates a purged flow rate of the evaporated fuel from the detected values of the pressure and temperature sensors and a time period during which the purge control valve is opened. On the basis of the calculated purged flow rate, a reduction correction is made to an amount of the fuel to be supplied to the engine in order to maintain an air-fuel ratio in the optimum condition. The calculated purged flow rate may be indicated.
