摘要： An engine includes a variable compression-ratio mechanism adapted to change a compression ratio of an engine and a supercharger adapted to supply a compressed air to the engine. An engine control device that controls the engine controls the variable compression-ratio mechanism by setting target compression ratio such that the higher responsiveness of a supercharging pressure rise by the supercharger is, the lower the target compression ratio is.

摘要： The invention relates to a method for determining the pressure Pavcm upstream of a mechanical compressor (3) equipped with a double supercharging circuit of a combustion engine. The pressure Pavcm is determined by a dynamic model based on a law of conservation of flow rate in the volume upstream of the mechanical compressor. The model links the pressure Pavcm upstream of the mechanical compressor (3) to a temperature Tavcm upstream of the mechanical compressor (3), to a boost pressure Psural and boost temperature Tsural on the intake side of the engine, and to an openness Bypass of the bypass valve (4).

摘要： A method is provided for controlling a pre-spin operation of a compressor of an internal combustion engine provided with a turbocharger. The presence of a turbocharger imposes additional requirements on the method. The wear of a compressor clutch is proportional to the transferred energy when the clutch is engaged. In order to reduce the wear of the compressor clutch, or increase the maximum engine speed where it is allowed to engage the compressor, a compressor pre-spin operation is used to reduce the transferred energy when the clutch is engaged. The pre-spin is achieved by controlling the air mass flow over the compressor by controlling a bypass throttle angle of a bypass throttle. The bypass throttle is provided in a parallel conduit to the compressor, bypassing the compressor. Since the air mass flow over the compressor affects the air mass flow to the turbocharger, the method takes the turbocharger into consideration.

摘要： An engine system includes a throttle valve configured to variably open and close to selectively restrict a volume of air flow. The engine system also includes a supercharger comprising an air inlet, an air outlet, a rotatable drive shaft and rotors associated with the drive shaft, wherein the supercharger is sized to have a flow rate that substantially prevents backwards leaking of air flow. The engine system further includes a combustion engine comprising combustion chambers and an associated rotatable crank shaft and a continuously variable transmission (CVT) configured to variably transfer rotational energy between the drive shaft and the crank shaft.

摘要： At high temperature, namely, when the temperature of intake air is higher than a predetermined normal temperature range, an ECU (25) controls a variable valve timing mechanism (24) such that the timing for closing an exhaust valve (9) is adjusted to a retard side, thereby reducing the amount of high-temperature internal EGR gas to avoid the occurrence of pre-ignition. At intermediate load and high load, the ECU (25) makes the retard amount of the timing for closing the exhaust valve (9) larger than that at low load, thereby reducing the amount of internal EGR gas. At intermediate load and in an intermediate-revolution range or a high-revolution range, the rotating speed of an electric motor (16) is increased to raise a supercharging pressure exerted by a supercharger (17). At high load and in the high-revolution range, the electric motor (16) for the supercharger (17) and an EGR control valve (22) are controlled such that the supercharging pressure rises and the amount of external EGR gas increases as the temperature of intake air detected by a temperature sensor (26) rises.

摘要： An air intake system for a supercharged automotive engine has an independent air intake passage an end of which is communicated independently and separately with a combustion chamber of each cylinder and a supercharger for supercharging intake air. The air intake valve closing timing is delayed after bottom dead point and the independent air intake passage is shaped so that the number of revolutions which causes maximum inertia in the independent air intake passage by supercharging in a high-speed region is higher than the number of revolutions of the engine at which maximum horse power is generated.
