摘要:
An engine system and method for improving engine starting are disclosed. In one example, engine port throttles are adjusted to improve fuel vaporization of a fuel that includes alcohol. The system and method may improve engine starting and emissions.
摘要:
A method for operating an engine of a vehicle, the engine having one or more deactivatable cylinders, the method including controlling the stability of a vehicle in response to vehicle acceleration, and reactivating or deactivating combustion in at least a cylinder in response to vehicle acceleration.
摘要:
A fuel system for an engine of a vehicle and a method of operating the fuel system are described. As a non-limiting example, the fuel system is controlled in response to engine operating conditions.
摘要:
A system and method for delivering EGR to an internal combustion engine is presented. The system can reduce system cost and lower system complexity.
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:
A system for an engine, comprising of a cylinder of the engine; a first injector configured to inject a first substance to said cylinder; a second injector configured to inject a second substance to said cylinder; and a controller configured to commence combustion in the engine by injecting fuel into said cylinder, where said fuel is injected by only one of said first and second injectors during said start and/or warm-up.
摘要:
A method is described for starting an internal combustion engine. During a run-up in engine speed of the engine starting, the method includes adjusting intake valve closing timing in response to barometric pressure to provide a desired air amount in the cylinder, with a longer valve opening with respect to crankshaft angle at higher altitudes as compared to a shorter valve opening with respect to crankshaft angle at lower altitudes for a given operating constraint.
