Abstract
A combustion engine with direct injection has in each cylinder a fuel injector (3) whose fuel orifices (4) are so oriented that the projection (5′) of the direction of each fuel spray, viewed in a plane perpendicular to the cylinder centerline, crosses a projection (8′, 8″, 9′, 9″) in the same plane of the valve disc of one of the valves.
Claims10
A cylinder and fuel injector combination for a direct injection combustion engine, wherein the combination comprises:
- an engine cylinder having a longitudinal direction and a center line along the longitudinal direction;
- an engine piston in and movable through the cylinder in the longitudinal direction;
- at least one inlet valve to the cylinder and at least one exhaust valve from the cylinder, both communicating into the cylinder above the piston;
- each of the valves including a valve disk which is in the cylinder and each valve disk being in a respective plane;
- a fuel injector having a plurality of fuel injecting nozzles disposed in the cylinder;
- the nozzles being positioned and oriented so that each nozzle delivers a respective spray of fuel in a respective direction in the cylinder, the nozzles being so oriented in the cylinder that the projection of the direction of a spray of fuel from every nozzle, as viewed in a plane perpendicular to the longitudinal direction center line of the cylinder, crosses a projection in the same plane as the valve disk of one of the valves.
