摘要： A supercharging system has a turbocharger driven by exhaust-gas of the engine, a supercharger driven by an engine and communicated with the turbocharger and the engine in series. A clutch is provided in a device for driving the supercharger and a bypass having a control valve is provided around the supercharger. A control unit is provided to respond to engine operating conditions for operating the clutch and the control valve. The control unit operates to disengage the clutch at light load on the engine in a predetermined low engine speed range, to engage the clutch at heavy load in the low engine speed range, and to disengage the clutch in a predetermined high engine speed range. The control valve is gradually opened in accordance with variation of engine operation conditions when the engine operation is in a transient state.

摘要： Each cylinder of an internal combustion engine has two intake valves, two exhaust valves, a fuel injector and a spark plug. The fuel injector is vertically provided in a cylinder head of the engine such that a nozzle of the fuel injector is located in a central position of a combustion chamber. The spark plug is disposed between intake ports of the intake valves, so that an electrode of the spark plug is located near the nozzle of the fuel injector.

摘要： In an in-cylinder fuel injection engine capable of selectively switching a combustion strategy from a stratified charge combustion to a homogeneous charge combustion and vice versa, when a coolant temperature at engine start is lower than a specified temperature, the combustion strategy is established to be a homogeneous charge combustion mode and this homogeneous charge combustion mode is held until the coolant temperature reaches the specified temperature. While the coolant temperature is higher than the specified temperature and lower than a warm-up completion temperature, the combustion strategy is switched from homogeneous to stratified by lowering the engine load from a high load area to a low load area so as to improve emissions and fuel economy. On the other hand, when the engine is restarted at the coolant temperature higher than the specified temperature, the combustion strategy is established to be homogeneous until the fuel pressure reaches a specified value and is switched from homogeneous to stratified after the fuel pressure reaches the specified value.
摘要翻译：在能够选择性地将燃烧策略从分层充气燃烧切换到均质燃料燃料的缸内燃料喷射发动机中，反之亦然，当发动机起动时的冷却剂温度低于规定温度时，建立燃烧策略为均匀充气燃烧模式，并且保持均匀充气燃烧模式，直到冷却剂温度达到指定温度。当冷却剂温度高于指定温度并低于预热完成温度时，通过将发动机负载从高负荷区域降低到低负荷区域，燃烧策略从均匀转换为分层，以改善排放和燃油经济性。另一方面，当发动机在比指定温度高的冷却剂温度下重新起动时，建立燃烧策略是均匀的，直到燃料压力达到规定值并在燃料压力达到规定值之后从均质转换为分层值。
