摘要： A fuel injection device comprises electrically controlled fuel injectors, each opening into an air induction passage upstream of a respective intake valve of a combustion chamber. Each injector has an air-fuel mixture chamber. A throttle valve in the induction passage is constructed to close it when in a minimum opening position. An air line connects the induction passage to the mixture chambers and has an additional air electrically controlled valve. A supplemental electrically controlled valve is branched out of the line and opens into the induction passage downstream of the throttle valve. An electronic unit controls the injectors and the supplementary valve and opens the supplemental valve during cold start of the engine at low temperature and during operation of the engine as a brake at normal temperature, high speed and with the throttle valve closed.

摘要： A carburetor including a throttle valve for regulating the flow of air through the body of the carburetor and to an engine, with fuel being introduced into the air flow for intermixture therewith, and with the device including an air actuated element which is preferably located downstream of the throttle valve and is adapted to be displaced automatically by the air to different positions varying in correspondence with the rate of air flow through the device, and which forms a restriction varying in size with the rate of air flow and acting to enhance dispersal of the fuel within the air and assure intimate intermixture of the air and fuel for optimum functioning of the engine. The fuel may be premixed with a secondary flow of air before delivery of the fuel and secondary air as a combined stream into the primary flow of air, and the combined stream may be drawn by vacuum into the primary flow of air at the location of the restriction formed by the flow actuated member. Precise control of the amount of fuel which is fed into the primary flow is attained by automatic regulation of a valve controlling the amount of secondary air which is mixed with the fuel. A proper air-fuel ratio may be assured by utilizing movement of the air actuated element to control operation of the secondary air valve. Additional automatic controls for starting and idle purposes are actuated by a vacuum responsive element and a thermostatic element.

摘要： Air intake side secondary air supply system for an internal combustion engine includes first and second secondary air supply passages leading to an intake manifold in which an open/close valve and an air control valve are respectively provided for a proportional control and an integral control of secondary air. In order to improve a driveability of the engine when no load is applied to the engine when the engine temperature is low, the air control valve is supplied with a pressure for rapidly closing the second air intake side secondary air supply passage so as to stop at least the integral control of the feedback control of air/fuel ratio immediately when a no-load condition is detected during a cold operation of the engine.

摘要： A thermostatic valve mounted in an air cleaner has an inlet connected to an intake manifold of an engine and an outlet connected to a negative pressure chamber of a negative pressure motor for actuating a switching valve pivotally mounted in a throat of the air cleaner, by the opening of the switching valve warmed air around an exhaust manifold of the engine being introduced into the air cleaner for the purpose of ensuring a smooth starting and operation of the engine. The thermostatic valve, for controlling the introduction of the warmed air as well as an amount of additional air fed to the engine as a function of the temperature in the air cleaner, has inside thereof a first passageway communicating the inlet with the inside thereof, a second passageway communicating the outlet with the inside and a third passageway communicating the inside with the air cleaner. A valve member is operatively disposed in both of the first and third passageways for respectively controlling the opening area of the first passageway and the opening and closing of the third passageway, so that the amount of the additional air is controlled through the first passageway and the application of the negative pressure from the intake manifold to the negative pressure motor is controlled by the closure and opening of the third passageway.
