摘要： A fuel supply control method for an internal combustion engine. Sensors read out values for engine speed, intake pipe absolute pressure and exhaust pipe absolute pressure. These values are used to determine a corrected value of intake pipe absolute pressure which, in turn, is used to determine the amount of fuel to be supplied to the engine.

摘要： A diesel engine intake system including a timing valve which is positioned in the intake system in engine starting and warming-up period under a cold engine condition. The timing valve is opened in the final period of the intake stroke so that a strong suction pressure is produced in the combustion chamber before the timing valve is opened. When the timing valve is opened, the intake air is rushed into the combustion chamber at a high speed whereby the intake air is compressed under the inertia of the high speed flow to thereby increase the temperature of the intake air. The timing valve is responsive to the suction pressure in the combustion chamber and opened when the suction pressure becomes stronger than a predetermined level.

The timing valve is opened in the final period of the intake stroke so that a strong suction pressure is produced in the combustion chamber before the timing valve is opened. When the timing valve is opened, the intake air as rushes into the combustion chamber at a high speed, whereby the intake air is compressed under the inertia of the high speed flow to thereby increase the temperature of the intake air. The engine is also provided with a blow-by passage and an exhaust gas recirculation passage, both opening to the intake passage upstream of the timing valve, so that it is possible to prevent the blow-by gas and the recirculated exhaust gas from being drawn under the suction pressure when the timing valve is closed.

摘要： Several embodiments of induction systems for multiple cylinder internal combustion engines that improve engine performance, particularly at idle and low speed. In each embodiment a charge is delivered to the chambers at idle and low speed through a relatively small cross sectional area auxiliary induction system for improving turbulence in the chamber at the time of combustion. The auxiliary induction passages communicate with each other so that the idle charge for a given chamber that is on its intake cycle will be supplied from the portion of the other induction systems downstream of a manually operated throttle valve. Upstream of the manually operated throttle valves there is provided another throttle valve which cooperates with an idle fuel discharge so that the idle fuel is delivered to the various chambers.
