摘要： A method of controlling fuel injection to an internal combustion engine to reduce cylinder wall wetting, smokiness, and unclean combustion, on a cumulative basis, applies a self-adaptive control on a gasoline injection initial angle. Gasoline injection initial or original angle is known, being preset, and a self-adaptive controlling volume is added. The self-adaptive controlling volume is the addition of a first self-adaptive controlling volume and a second self-adaptive controlling volume to the original angle. The first self-adaptive controlling volume relates to predicted load and an engine coolant temperature. The second self-adaptive controlling volume is based on the rotating speed of the engine. Cylinder wall wetting is reduced or avoided, smoke is reduced, and cleaner combustion is achieved. An engine fuel injection control apparatus applying the method is also provided.

摘要： The present disclosure provides a method for controlling EGR rate of a low pressure EGR system, a system and a vehicle. The method calculates a molar concentration of water molecules of exhaust gas processed by EGR cooler, calculates a molar concentration of water molecules, obtains coefficient as to excess air, and calculates a molar volume ratio of air according to the coefficient. Under a maximum limit of humidity, an allowable EGR rate of the exhaust gas processed by the EGR cooler is determined and an allowable EGR rate of the mixed gas before entry into supercharger and/or compressor is also determined, a lower EGR rate between the two allowable rates is set as a maximum for application actual working conditions. The present disclosure solves a problem of condensation caused by an introduction of exhaust gas from the existing gasoline engine.
