    • One strategy for reducing undesirable emissions from internal combustion engines relates to finding ways to better mix fuel and air prior to combustion. One such method is commonly referred to as homogenous charge compression ignition (HCCI); however, that strategy is problematic in both controlling ignition timing and avoiding overstressing the engine at higher speeds and loads. The present invention addresses these issues by mixing air and fuel vapor within an injector instead of within the engine cylinder. The air/fuel mixture is then injected into the engine cylinder at some desired timing and over some desired duration. Such a strategy permits for lower emissions due to better mixing of air and fuel, while also permitting control over some aspects of combustion timing and duration not apparently possible with a conventional HCCI strategy. The present invention is generally applicable to all internal combustion engines, but especially applicable to diesel engines.
    • 减少内燃机不良排放的一个策略是寻找在燃烧之前更好地混合燃料和空气的方法。 一种这样的方法通常被称为均匀充电压缩点火(HCCI); 然而,该策略在控制点火正时以及在较高速度和负载下避免发动机过应力的问题。 本发明通过将喷射器内的空气和燃料蒸汽而不是在发动机气缸内混合来解决这些问题。 然后将空气/燃料混合物在某个期望的时间和超过一些期望的持续时间内喷射到发动机气缸中。 这种策略允许由于空气和燃料的更好混合而降低排放,同时还允许通过常规HCCI策略控制燃烧正时和持续时间的某些方面显然不可能。 本发明通常适用于所有内燃机,但特别适用于柴油发动机。

    • A method and system for adjusting the application of map limits to compensate for injector variability in an electronically controlled fuel injection system is disclosed. Fuel quantity limiting maps are stored in memory within the electronic control module of an electronically controlled fuel injector system. The application of the fuel quantity limiting maps is adjusted for individual injector performance characteristics. If a fuel injector dispenses too much fuel at a particular on time, the quantity limited in the map limit is decreased. Similarly, if a fuel injector dispenses too little fuel at a particular on time, the quantity limited in the map limit is increased. As one result, limiting maps do not unduly limit fuel quantity for an injector dispensing too little fuel at that on time due to injector variability. As another result, limiting maps properly limit fuel quantity for an injector dispensing too much fuel at that on time due to injector variability.
    • 公开了一种用于调整地图限制的应用以补偿电子控制的燃料喷射系统中的喷射器变化性的方法和系统。 燃料量限制图存储在电子控制燃料喷射器系统的电子控制模块内的存储器中。 针对各个喷油器性能特征调整燃料量限制图的应用。 如果燃料喷射器在特定的时间分配太多的燃料,则限制在地图极限中的数量减少。 类似地,如果燃料喷射器在特定的时间点分配太少的燃料,则在地图限制中限制的量增加。 因此,由于喷射器的变化,限制图不会不适当地限制喷油器在燃油喷射时分配太少燃料的燃油量。 另一个结果是,由于喷射器的变化,限制图适当地限制了喷油器在燃油喷射器分配太多燃料的燃油量。
