Abstract (en)

[origin: WO2015069265A1] A direct fuel injection method and an internal combustion engine provided with appropriate sensors and data input lines to an Engine Control Unit (ECU) for performing this method. The method includes inputting at least data inputs representing a piston position, a rotational speed of the internal combustion engine, and a torque demand into an ECU, calculating in the ECU a calculated start of injection (SOI) for the direct fuel injection that is next based on the data inputs, calculating based on the data inputs and the calculated SOI a desired fuel temperature prior to the direct fuel injection that is next, heating fuel with a system delay not to exceed 5 seconds to the desired heated fuel temperature prior to a direct fuel injection, injecting the heated fuel, and repeating the aforementioned method steps for subsequent direct fuel injections.
