摘要： In a vehicle diagnosis information communication system, electric power is supplied from a battery to a vehicle control computer mounted on the vehicle during a period of vehicle operation, while the electric power is supplied to a radio communication unit mounted on the vehicle irrespective of the vehicle operation. The computer transmits a vehicle information such as engine diagnosis result to the radio communication unit through a communication line. The radio communication unit communicates the received vehicle information to an external site of communication in response to a request of the information form the external site of communication irrespective of the supply of the electric power to the computer. Preferably, the supply of the electric power from the battery to the computer is maintained for a predetermined period after the vehicle operation.

摘要： An exhaust gas recirculation system for an internal combustion engine employs a recirculation control valve in a passageway connecting the engine exhaust passage to the engine intake passage downstream from the throttle valve. An air conduit having an air control valve therein draws atmospheric air into the intake passage downstream from the throttle valve. Vacuum responsive actuators are provided for each of the control valves and they are operated by vacuum pressure controlled by a regulating valve, which regulating valve is responsive to differential pressure between vacuum intensity in the intake passage upstream from said throttle valve and modified atmospheric pressure. The modified atmospheric pressure is obtained downstream of a fixed or variable restriction in the air conduit.

摘要： A fuel supply control system for an internal combustion engine having a throttle body, and a fuel injection valve arranged in an intake manifold upstream of the throttle body for supplying fuel to all cylinders. An air throttle valve has a valve body having a notched opening formed therein and disposed to be opposite the nozzle of the fuel injection valve to increase the flow speed of intake air in the vicinity of the nozzle when the air throttle valve is fully closed. An electronic control unit controls the fuel injection valve in response to operating conditions of the engine. The electronic control unit causes the air throttle valve to be fully closed when a predetermined low rotation-speed operating condition of the engine, in which at least the rotational speed of the engine is lower than a predetermined value, is satisfied. The predetermined value of the rotational speed of the engine is set such that the lower the atmospheric pressure the smaller the predetermined value.

摘要： An auxiliary fuel system for an internal combustion engine which supplements the primary fuel means for delivering fuel through a carburetor passage to said engine. The auxiliary fuel system is comprised of first and second fuel valves placed in parallel which introduce extra fuel into the intake passage of the carburetor at heavy load conditions. The first fuel valve is of the diaphragm operated type and opens and closes as a function of the pressure in a first vacuum chamber being alternatively connected to either a vacuum source at the intake passage of the carburetor or to the atmosphere. A series of electromagnetic selector valves and check valves determine the pressure conditions within said vacuum chamber. The second fuel valve is also of the diaphragm operated type, but the diaphragm is actuated by a mechanical linkage system interconnected to the throttle valve. As in the first fuel valve, movement of the dash pot diaphragm is a function of the pressure in the dash pot vacuum chamber which communicates with either the carburetor intake passage or to the atmosphere. A spark advance system is functionally interconnected to said auxiliary fuel feed control system. An electrical switching system controls the operation of both the auxiliary fuel system and the ignition timing control system so that addition of fuel during sudden non-steady state accelerations from medium speeds is delayed, and the air-fuel mixture is maintained leaner than the stoichiometric ratio. Harmful components exhausted into the atmosphere are thus minimized.
摘要翻译：用于内燃机的辅助燃料系统，其补充主要燃料装置，用于将燃料通过化油器通道输送到所述发动机。辅助燃料系统由平行放置的第一和第二燃料阀构成，其在重负载条件下将额外的燃料引入化油器的进气通道中。第一燃料阀是隔膜操作型，并且作为第一真空室中的压力的函数打开和关闭，该第一真空室交替地连接到化油器的进气通道处的真空源或者与大气相连。一系列电磁选择阀和止回阀决定了所述真空室内的压力状况。第二燃料阀也是隔膜操作型，但隔膜由与节流阀相互连接的机械联动系统致动。如在第一燃料阀中，仪表板隔膜的运动是与化油器进气通道或大气连通的仪表箱真空室中的压力的函数。火花提前系统在功能上与所述辅助燃料供给控制系统互连。电气开关系统控制辅助燃料系统和点火正时控制系统的操作，使得从中等速度的突然非稳态加速期间添加燃料被延迟，空气 - 燃料混合物保持比化学计量比。因此，排出到大气中的有害成分被最小化。
