摘要

#CMT# #/CMT# The engine (1) has a rotating camshaft (5) wedged in rotation with respect to a combustion piston (3). A fuel supply secondary pump (9) has a pump piston for varying the variation of a fuel circulation chamber. The pump piston is movable between a compression position in which the chamber presents a reduced volume and a decompression position in which the chamber presents a high volume than the reduced volume. The pump piston is mechanically connected to the rotating camshaft to drive the pump piston in displacement by the camshaft between the positions. #CMT#USE : #/CMT# Internal combustion engine. #CMT#ADVANTAGE : #/CMT# The configuration of the internal combustion engine suppresses the perturbation of the fuel injection in combustion chambers by the fuel injection in a waste gas exhaust conduit. The utilization of the secondary pump avoids the decrease in pressure and fuel flow passing through a combustion injector when the fuel is injected using an exhaust injector. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an internal combustion engine provided with an exhaust injector supplied by a fuel supplying secondary pump coupled with and driven by a rotating camshaft of the engine. 1 : Internal combustion engine 2 : Combustion chambers 3 : Combustion piston 4 : Combustion injector 5 : Rotating camshaft 6 : Waste gas exhaust conduit 9 : Fuel supply secondary pump.
