摘要： An internal combustion engine control device includes a valve closing time calculation unit, a valve closing delay time difference calculation unit that normalizes a plurality of valve closing delay times with a fuel pressure and calculates a valve closing delay time difference, a content rate calculation unit that calculates the synthetic fuel content rate of a fuel stored in a fuel tank based on characteristic data indicating the relationship between the valve closing delay time difference and the synthetic fuel content rate of synthetic fuel contained in the fuel, and a combustion control unit that controls an internal combustion engine such that the exhaust temperature of an exhaust gas discharged from a combustion chamber becomes equal to or higher than a threshold temperature based on the synthetic fuel content rate.

摘要： The present invention relates to a device and a method for controlling the start of an internal combustion engine, wherein the internal combustion engine is equipped with an ignition device comprising a fuel-fed prechamber to ignite an air-fuel mixture in a main combustion chamber. In order to reduce the emissions of the internal combustion engine during engine start a prechamber heating operations is performed by injecting a predetermined amount of fuel into the prechamber and igniting an air-fuel-mixture therein, while the main fuel injector is deactivated during at least a first engine cycle after engine start request.
