METHOD AND SYSTEM OF CORRECTING CONTROL SIGNAL FOR FUEL INJECTOR OF FUEL FORWARDING SYSTEM |
摘要 |
PURPOSE: To improve hot start fuel control by calculating a net amount of heat transferred to a fuel delivery system and compensating for increasing in volatility of a heated fuel. CONSTITUTION: A fuel delivery system 10 comprises a fuel pump 11 and a plurality of fuel injectors 12 for injecting a liquid fuel into an internal combustion engine 14 of a motor vehicle. A method for modifying a control signal comprises the steps of generating a first set of temperature signals based on the temperature of the engine 14; and storing a data representation of a first shut-down temperature signal of the first set of temperature signals in memory. The method specifically comprises the step of calculating a correction factor based on a net amount of heat transferred to the fuel delivery system; and modifying the control signal based on the correction factor to obtain a modified control signal. According to this modified control signal, the fuel injectors 12 can be accurately controlled by compensating for the volatility of the fuel. |
