Method managing fuel supply of internal combustion engine i.e. diesel engine, of power unit of car, involves determining temperature of air-fuel mixtures, and adjusting noise of combustion according to temperature of air-fuel mixtures

摘要

The method involves determining temperature of air-fuel mixtures (E3), and adjusting noise of combustion according to the temperature of the air-fuel mixtures. A phase in which the fuel is supplied to an internal combustion engine, is designed with a fuel injection mode in a dual pre-injection to reduce the noise in the internal combustion engine. The phase is activated when the given temperature is lower than a threshold calibrated value from the predetermined temperature, where the determined temperature ranges preferably between 20 degree Celsius and 80 degree Celsius. Independent claims are also included for the following: (1) a managing device for fuel supply of an internal combustion engine (2) a power unit of a car (3) a computer program comprising a set of instructions to perform a method for managing fuel supply of an internal combustion engine of a power unit of a car.
