Abstract
The invention relates to a control process for charge flow management devices as arranged in the intake area of the inlet ports of direct-injection internal combustion engines and port-injection type internal combustion engines having intake ports into which no fuel is injected. The process is characterized by the fact that the charge flow management devices are not closed when the engine operates on overrun. This reduces fouling on the intake valves produced by fuel and lubricant residue.
Claims1
Control method for charge flow management devices mainly as fitted in direct-injection type internal combustion engines wherein such charge movement management devices are arranged in intake ports, characterized in that said charge flow management devices are not closed when the internal combustion engine is operating on overrun.
