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： 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 V-type engine is constructed so that one bank of cylinders is located rearward, in a longitudinal direction of the engine, relative to the other bank of cylinders so that a space is formed in front of a front surface of a cylinder block of the engine. In the space, a casing or casings for a fluid passage are provided. Supplemental apparatuses, such as a water pump, an alternator, a compressor, and an oil pump, are formed so as to be driven by belts transmitting drive power from a crankshaft of the V-type engine. One of the belts has tension applied to it by a tensioner, which is formed on a bracket. The bracket is fixed to the casing or casings by bolts, which are used for both fixing the casing or casings to the cylinder block and for fixing the bracket to the casing or casings. As a result, both of the bracket and the casing or casings are firmly fixed to the cylinder block within a compact space, even when the tensioner is located far from the front surface of the cylinder block.

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： An internal combustion engine comprises a primary supercharger operated in substantially a full range of engine operating conditions of a vehicle and a secondary supercharger operated in a specific range of the engine operating condition. The plurality of supercharger are arranged in parallel in the fore and aft direction of a vehicle in a manner such that the primary supercharger means is disposed forward of the secondary supercharger. The primary supercharger is disposed at a front portion of an engine room, just behind a cooling fan, to easily be provided with a cooling effect by virtue of a fresh air. The secondary supercharger is disposed rearward of the primary supercharger to avoid the cooling effect provided by the fresh air and to receive air warmed by the primary supercharger so to undergo a warming up effect.
