摘要： In an exhaust gas cleaning apparatus a ceramic heating resistor has a lattice-shaped exhaust gas passage and is formed by extrusion. The ceramic heating resistor is fixed closely to the upper stream side of a filter which catches particulates contained in exhaust gas. This heating resistor is divided into a plurality of sections so that heating current is successively supplied to the divided sections.

摘要： In a device for purifying the exhaust gases discharged from an internal combustion engine of the type having a secondary air supply pipe for charging the secondary air from an air source such as an air pump into an exhaust pipe upstream of an exhaust gas reactor or the like, a three-way valve is inserted in the supply pipe in such a manner that the three-way valve may be displaced between a first position at which the air source and the exhaust pipe are communicated with each other and a second position at which the communication between them is interrupted and the secondary air is relieved or returned to the air source bypassing the exhaust pipe; an air-fuel ratio sensor is inserted into the exhaust pipe downstream of the opening of the secondary air supply pipe into the exhaust pipe; and means for controlling the three-way valve is provided so that when the air-fuel ratio detected by the sensor is lower than a reference or optimum ratio at which the best performance of the reactor is expected the three-way valve is caused to move to the first position, whereas when the sensed air-fuel ratio exceeds the reference ratio, the three-way valve is caused to move to the second position, whereby the air-fuel ratio may be controlled with a higher degree of accuracy.

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.
摘要翻译： 用于旋转活塞发动机的点火系统除了正常的火花塞和火花塞之外还包括电热塞。 电热塞在转子旋转方向相对于摆线短轴的前方安装在发动机的壳体中，并且在发动机的低速和负载操作期间连续点燃混合物。 因此，在低速和负载操作期间，电热塞代替先导火花塞进行点火，而在其它发动机运行状态期间，先导火花塞和尾火花塞执行混合物点火。

摘要： An ignition system for rotary piston engine wherein a glow plug mounted in the epitrochoidal housing of the engine is supplied with electric power to maintain the surface temperature of the glow plug within a range from 900.degree. to 1100.degree. C. A control unit for controlling the supply of electric power to the glow plug produces an output pulse signal the pulse width thereof being varied depending on engine operating conditions such as the amount of fuel supply and engine rotational speeds. A power circuit receives the pulse signal from the control unit and on-off controls the supply of electric power to the plug from a battery.

摘要： An engine exhaust gas purification system having an exhaust gas reactor mounted on the engine exhaust pipe, a secondary air supply system having a secondary air supply passage connected to the exhaust pipe upstream of the reactor, and an exhaust gas air-fuel ratio detector mounted on the exhaust pipe to detect air-fuel ratio of exhaust gases in the exhaust pipe. A secondary air supply control valve is provided in the secondary air supply passage and controlled by a valve actuator having a diaphragm to which positive pressure of the secondary air and the engine intake vacuum pressure can be applied. The application of the positive and vacuum pressures to the diaphragm is controlled by solenoid valves which are controlled in accordance with the air-fuel detector output voltage which represents the detected exhaust gas air-fuel ratio, whereby the secondary air supply control valve is controlled such that the secondary air is supplied to the engine exhaust gases at a continuously controlled, variable rate.

摘要： An intake system for intercommunicating a carburetor and a combustion chamber of internal combustion engines which has a cylinder head, an intake port provided in the cylinder head, an intake valve located in the intake port and an exhaust manifold communicated with the combustion chamber. At least two intake passages are provided to join together at that part in the intake port which is immediately before the intake valve. One of the intake passages passes through the exhaust manifold, whereby the atomized fuel particles in an air-fuel mixture to be sucked in the combustion chamber can be positively vaporized without accompanying high temperature rising of the mixture.
