Mixture formation improvement for IC engine - using injection pump for richer mixt poor mixture being supplied direct to cylinder through constriction

摘要

Installation to improve the mixture formation and layer charging with I.C. engines, where the richer mixture is brought into the combustion chamber by an injection pump fitted to each cylinder whilst pure or combustion air with little fuel is supplied to the working cylinder of the engine. Between combustion chamber and working cylinder there is a construction acting like a Laval nozzle through which the combustion air flows during compression with the inlet channel for the richer mixture leading towards the low pressure area of the constriction.
