In an air compressing, internal combustion engine with direct fuel injection, a rotation-symmetrical combustion chamber is positioned in a piston. Combustion air circulates around the longitudinal axis of the combustion chamber at the moment of fuel injection. An injection nozzle is provided from which the fuel is injected in at least two fuel jets into the combustion chamber. The engagement points of the fuel jets on the circumferential wall of the combustion chamber are evenly distributed over said wall. In addition, the engagement points are in different planes disposed normal to the longitudinal axis of the combustion chamber while being spaced from each end thereof. In one embodiment, the injection nozzle is coaxially disposed and emits three fuel jets, the engagement points of which are located in different planes evenly spaced from one another. In another embodiment the injection nozzle is offset with respect to the axis of the combustion chamber with the fuel jets being of substantially equal length. In a further embodiment, at least four fuel jets are emitted from a coaxially disposed injection nozzle with the engagement points of oppositely arranged pairs of fuel jets being in the same plane.

Apparatus for distribution of fuel from an injection nozzle with respect

A fuel injection system for an internal combustion engine includes an air suction pipe, a throttle valve located in the pipe, and a member, upstream of the throttle valve, which is actuatable by air flowing through the suction pipe so as to move a piston valve to dose a quantity of fuel to a fuel injection nozzle. The system includes a duct which bypasses the throttle valve, the duct having a valve which closes the duct when the throttle valve is closed and when the engine is above the idling speed. Dosing of fuel is thereby stopped during coasting of a vehicle, leading to decreased fuel consumption.

Fuel injection system for an internal combustion engine

The invention relates to a fuel injection rotary piston internal combustion engine of the trochoidal type with a housing made up of a peripheral portion and two side walls and with a first injection nozzle in the peripheral portion and a second injection nozzle in the inlet port, which are connected to a fuel metering device and of which the delivery quantities are adjustable. A fuel delivery device continuously injects a quantity of fuel proportional to the air intake and is in permanent communication with the first nozzle. Control means connect the second nozzle to the fuel delivery device only from a predetermined part-load up to full load conditions.

The invention concerns a reactor for afterburning of unburned constituents in the exhaust of an internal combustion engine, consisting of a jacketed heat-insulated reactor chamber into which at least one inlet pipe passing through the jacket and communicating with an outlet passage of the engine opens tangentially, being traversed by exhaust gases mixed with secondary air, and having an outlet pipe for escape of exhaust gases from the reactor chamber. The reactor chamber in cylindrical in shape and the inlet pipe opens into the reactor chamber tangentially and the outlet pipe is passed out of the reactor chamber tangentially from the inlet pipe in the direction offset of flow.
