    摘要: An intake port device comprises an intake port (9) formed by a straight part (13) and a helical part (15), and a valve (17) disposed adjacent to the inlet of the intake port. In order that intake air flow having a large swirl ratio can be supplied to an engine without being encountered with a large resistance even in a light-loaded condition of the engine, the valve (17) is held in its closed position without causing any sharp decrease in the coefficient of intake air flow when closed. In a modification of the intake port device, the valve (17) holds open the lower half of the intake port 9 in its closed position, so that intake air flow having a large swirl ratio can be supplied without being encounted with a large resistance even when the load of the engine is light. In another modification of the intake port device, the free end of the valve (17) is bent and deformed in the downstream direction of intake air so that the flow of intake air may not be encountered with a large resistance.

    摘要: An air/fuel ratio control system is provided for use with an internal combustion engine. The system includes a first air/fuel ratio detector arranged on an upstream side of a catalytic converter so as to detect the air/fuel ratio of the engine from components of exhaust gas, a second air/fuel ratio detector arranged in the exhaust system and having a detection response speed slower than the first air/fuel ratio detector, a device for controlling the air/fuel ratio of the engine on the basis of results of a comparison between a detection value from the first air/fuel ratio detector and a predetermined first reference value, a device for effecting a correction to the control of the air/fuel ratio by the air/fuel ratio control device on the basis of results of a comparison between a detection value from the second air/fuel ratio detector and a predetermined second reference value, and a device for shifting the second reference value to a lean air/fuel ratio side in a specific operation state of the engine.

    摘要: An internal combustion engine has a combustion chamber which communicates via an injection port with an injection chamber whose volume is 0.5 cc.about.1.5 cc. During the intake stroke, air-fuel mixture is introduced from an intake port into the combustion chamber, and at the same time, under the influence of high vacuum produced in the combustion chamber, a jet stream of exhaust gas, air or air-fuel mixture is violently injected from the injection port into the combustion chamber via an auxiliary intake passage communicates with the injection chamber through an auxiliary intake valve, so that the jet stream enhances the ignitability by scavenging burned gases from around a spark gap and also generates strong swirl and turbulence of air-fuel mixture in the combustion chamber.

    摘要: An engine controlling system for a vehicle is disclosed which is suitable for use with an automobile. When a treadled condition detection signal is developed from an accelerator pedal operated condition detector, a first control amount setting device sets a control amount of an engine output adjusting device in accordance with an operation amount detection signal. When a treadled condition cancelling detection signal is developed from the accelerator pedal operated condition detector, a second control amount setting device sets, if it receives a constant speed running designating signal from a running condition designating device in accordance with a running speed detection signal from a running speed detector, a control amount of the engine output adjusting device necessary to make the running speed of the vehicle equal to an aimed speed. However, if it receives an accelerated running designating signal from the running condition designating device, the second control amount setting device sets a control amount of the engine output adjusting device necessary for the vehicle to accomplish accelerated running.
