摘要： In one class of fuel injection systems, the individual fuel injectors cycle between high and low pressure during and between injection sequences in a given engine cycle. The fuel injectors may be hydraulically actuated, mechanically actuated, and possibly include common rail injectors equipped with an admission valve that enable the fuel injectors to cycle between high and low pressures. Many of these fuel injection systems also include a directly controlled nozzle valve that can apply or relieve pressure on a closing hydraulic surface associated with the nozzle valve. The nozzle valve is typically spring-biased and therefore has a pre-defined valve opening pressure that defines at what fuel pressure the nozzle valve will open when pressure is relieved on its closing hydraulic surface. While these fuel injection systems can produce a wide variety of rate shapes and injection sequences, generally, an injection sequence of particular interest is one that includes a relatively small volume pilot injection followed quickly in time by a relatively large volume main injection. In order to make the accuracy of the pilot injection more consistent, the nozzle valve is held closed while fuel pressure in the fuel injector builds and surpasses the valve opening pressure of the nozzle valve. This strategy helps to alleviate sensitivity of the pilot injection volume to inherent variability factors, such as geometrical tolerances, within and between fuel injectors.

摘要翻译： 在一类燃油喷射系统中，单个燃油喷射器在给定的发动机循环期间和在喷射序列之间在高压和低压之间循环。 燃料喷射器可以是液压致动的，机械致动的，并且可能包括配备有允许燃料喷射器在高压和低压之间循环的进气阀的共轨喷油器。 这些燃料喷射系统中的许多还包括直接控制的喷嘴阀，其可以施加或释放与喷嘴阀相关联的关闭液压表面上的压力。 喷嘴阀通常是弹簧偏置的，并且因此具有预定义的开阀压力，其限定当在其关闭液压表面上释放压力时喷嘴阀将打开什么燃料压力。 虽然这些燃料喷射系统可以产生各种速率形状和喷射序列，但通常，特别感兴趣的喷射序列是包括相对较小体积的先导喷射的喷射序列，其通过较大体积的主喷射在时间上快速跟随。 为了使引燃喷射的精度更加一致，喷嘴阀在燃料喷射器中的燃料压力建立并且超过喷嘴阀的开阀压力时保持关闭。 该策略有助于减轻引燃喷射体积对燃油喷射器内和燃油喷射器之间的内在变异因素（如几何公差）的敏感性。

摘要： An internal combustion engine (10) has an intake system (12) that includes a turbocharger (32). An engine control (30) processes data for controlling the opening of the exhaust valves (24) and for controlling fueling of the engine in relation to the engine operating cycle. In response to initiation of engine acceleration, the control increasingly retards exhaust valve opening in relation to the engine operating cycle to cause the turbocharger to increase pressure in the intake manifold (14) and increases engine fueling in relation to the increased pressure in the intake manifold.

摘要： A turbocharger (32) creates intake manifold boost for a diesel engine (10) that has a variable valve actuation mechanism. At times, exhaust valve opening (EVO) is increasingly retarded in relation to the engine operating cycle (56) to cause the turbocharger to increase boost, engine fueling is also increased in relation to the increased boost (58), and in response to any incipient surging of the compressor resulting from such increasingly retarded exhaust valve opening and such increased engine fueling, compressed charge air is bled from the intake manifold through the combustion chambers to the exhaust system (62) to counter the incipient surging and thereby avoid any significant turbocharger surge. The bleeding is accomplished by keeping the exhaust valves (24) slightly open beyond the time that they would otherwise close.
