Abstract
The invention relates to a method of control of an internal combustion engine comprising at least one electrically controlled inlet valve. To reduce hydrocarbon emissions by the cold engine, the opening of the valve is controlled in two successive phases (), the first phase () corresponding principally with the admission of fuel and the second phase () mainly corresponding with the air inlet. The opening of the valve is substantially lower during the first phase than during the second phase in order to pulverize the fuel into fine droplets during the first phase.
