摘要： Disclosed is an engine-control apparatus in which an exhaust passageway of the engine is provided with plural sound deadening passages. A portion of the plural sound deadening passages is designed to be opened or closed by a shift valve on the basis of a predetermined switching characteristic, and the pressure of the exhaust gases is changed upon the switching of the shift valve. In order to prevent torque shock to the driven wheels which may occur attendant upon operation of the shift valve to open or close or in order to reduce probability that torque shock would occur, there is provided a torque regulating apparatus which permits an adjustment of torque generator by the engine, of a transmission efficiency of power to the driven wheel, or of a switching speed at which the shift valve is switched to open or close, or a change in the switching characteristic.

摘要： In a supercharged engine, a part of the pressurized air pressurized by a supercharger is introduced into the exhaust system as secondary air in a predetermined operating range of the engine. The supercharging pressure is controlled to be lower when introduction of secondary air is effected than when it is not effected.

摘要： A two rotor type rotary piston engine includes an intake system comprised of individual light load intake ports and heavy load intake ports provided in at least one of the intermediate and side housings to open to the respective rotor cavities and adapted to be cyclically closed by the rotors as the rotor rotate, an intake passage including a throttle valve and individual light load and heavy load passages leading respectively to the light load and heavy load intake ports. The light load passages are communicated with each other by a communicating passage downstream of the throttle valve and the heavy load passages are also communicated each other by a further communication passage. The intake port timings and the passage lengths are so determined that pressure resonance effects can be obtained at both medium and high speed engine operations.

摘要： A rotary piston engine including a casing comprised of a rotor housing and a pair of side housings attached to the opposite sides of the rotor housing to define a rotor cavity. A substantially triangular rotor is disposed in the rotor cavity. The intake system includes a light load intake port formed in one of the side housings so as to open to the rotor cavity, a medium load and heavy load intake ports formed in the other side housing. The light load and medium load intake ports are formed so that they are opened to a working chamber after the chamber is disconnected from the exhaust port and closed substantially simultaneously. The heavy load intake port is associated with a control valve which is closed under light and medium load operations.

摘要： A fuel injection device for internal combustion engines, provided with a light load fuel injection valve and a heavy load injection valve for each cylinder of the engine. The light load fuel injection valve and the heavy load fuel injection valve are provided in an intake passage. The light load fuel injection valve is positioned close to the combustion chamber of the engine whereas the heavy load fuel injection valve is located further from the combustion chamber than the light load fuel injection valve. The fuel injection device is also provided with a control circuit which controls the light load fuel injection valve to provide additional supply of fuel during engine accelerating operation so that the increased fuel is rapidly introduced into the combustion chamber at the time of engine acceleration.

摘要： A two rotor type rotary piston engine includes an intake system comprised of light load intake ports provided in the intermediate housing and heavy load intake ports provided in side housings to open to the respective rotor cavities and being cyclically closed by the rotors as the rotor rotates, an intake passage including a throttle valve and individual passages leading respectively to the intake ports. The passages leading to the light load ports are communicated with each other by a communicating passage downstream of the throttle valve. The heavy load intake port includes a main port and an auxiliary port. The auxiliary port is normally closed but opened in high speed, heavy load operation by a control valve and has a closing timing later than that of the main port. The communication passage and the individual passages leading to the light load intake ports have overall length in relation to the port timings so that a compression wave produced in one individual passage in opening timing of one light load intake port is transmitted to the other light load intake port just before the other light load intake port is closed to obtain an additional charge under an engine speed in which the control valve is moved from the closed position to the open position or vice versa.

摘要： Intake system for a multiple cylinder internal combustion engine having primary and secondary passages leading to each cylinder and respectively provided with throttle valves. The primary passages for the respective cylinders are connected together through a first communicating passage of relatively large cross-sectional area and a second communicating passage of a relatively small cross-sectional area which is downstream of the first passage. One of the primary passages is provided with a shut-off valve which is located close to but downstream of the second communicating passage and adapted to be closed in idling operation or deceleration of the engine for directing the mixture totally toward the cylinder associated with the other primary passage. The primary and secondary passages leading to the same cylinder are connected together by a connecting passage downstream of the throttle valve. The connecting passage for the primary passage having the shut-off valve is located downstream of the shut-off valve so as not to weaken the function of the shut-off valve.
