Internal combustion engine with supercharging device

摘要

Main air feed devices, for example an air injection nozzle 13, are connected to the inlet manifold 6. Secondary air feed devices, for example an air injection nozzle 9, are provided on the inlet of the blower 5. Solenoid valves 22, 23 are provided on the respective pipelines opening into air feed devices automatically as a function of the variation in the load so as to deliver the required quantity of air rapidly to the combustion chamber. The invention prevents a fall in the speed of rotation of the engine and the emission of smoke in the event of load variations. <IMAGE>
