摘要： A fuel delivery approach for an engine includes delivering a first fuel blend from a first, lower alcohol fuel tank to a port injector; delivering a second, higher alcohol, fuel to a direct injector, and transferring the first fuel from the first tank to the second tank so that the first tank is emptied before the second. In this way, at least some fuel is available for direct injection even when the higher alcohol fuel is exhausted prior to the lower alcohol fuel. Thus, it is possible to at least obtain charge cooling benefits of direct injection, and therefore the engine may be operated with a greater amount of boost.
摘要翻译：用于发动机的燃料输送方法包括将第一燃料混合物从第一低级醇燃料箱输送到端口喷射器; 将第二高级醇燃料输送到直接喷射器，以及将第一燃料从第一罐转移到第二罐，使得第一罐在第二罐之前被排空。以这种方式，即使在低级醇燃料之前排出高级醇燃料，至少一些燃料可用于直接喷射。因此，可以至少获得直接喷射的充电冷却效果，因此发动机可以以更大量的升压来操作。
