Method for operating a compression-ignition internal combustion engine with at least one cylinder and a piston movable in the at least one cylinder, wherein the method comprises the steps: - Forming a combustible mixture by substantially homogeneously mixi...

A uniflow scavenging two-cycle engine includes a scavenge port which is provided on one end side in a stroke direction of a piston in a cylinder (110), and sucks an active gas; and a plurality of injection units (126g and 126f) which inject a fuel gas into...

An internal combustion engine 1 includes a fuel injection valve 6 that injects fuel to a combustion chamber E in which a swirl flow is generated. An injection direction of an injection hole 611H injecting fuel to a region E8 of the combustion chamber E thr...

An internal combustion engine 1 includes a fuel injection valve 6 that injects fuel to a combustion chamber in which a swirl flow is generated. For example, injection holes 611A and 611B are two adjacent injection holes among plural injection holes 611, an...

The engine has a fuel injector (6) fixed on a cylinder head (2) to inject fuel into a combustion chamber of a cylinder (5). The injector has fuel injection orifices arranged such that fuel jets (61) are directed towards peripheral surfaces (22) of the cham...

An injector (20) is centrally mounted in a cylinder head (12) and produces a conical spray. It has a dispersion angle (a1) such that there is a lowest position (PL) of the piston (18) which does not allow fuel to strike the cylinder (10) sides. For all pos...

A combustion system for direct injection diesel engines, having a fuel injection nozzle provided with upper and lower rows of nozzle holes and disposed so as to be opposed to a deep dish combustion chamber of a small opening ratio. The directions of the up...
