摘要： There is provided a compression ignition type gasoline engine operable under a stable lean burn condition with a high compression ratio, and which has a simple construction without using a pre-heating system for an air-fuel mixture. An intake port (5) communicates with a combustion chamber via an opening. The opening is closed by an intake valve (7). A fuel injection valve (9) is provided in the intake port (5) so as to inject an amount of gasoline inside the intake port (5) within a duration in which the opening is substantially closed by the intake valve. Heat is generated in the mixture in the combustion chamber by means of a high compression ratio so that the mixture is self-ignited only by heat generated by compression. The compression ratio ranges from about 14 to about 20.

摘要： A direct injection internal combustion engine of compression ignition type is provided with a piston cavity (2) offset (Os) from the position center (Op) and with an injection nozzle (3) which injects a hollow conical fuel spray having a tangential velocity component and relatively weak penetration into a swirl set up in the combustion chamber. The injection geometry and the offset are such that squish (S) and swirl flows (SW) interact to form an excellent air-fuel mixture over the whole volume of the cavity without forming local fuel concentrations or wetting the cavity wall.

摘要： @ A direct injection internal combustion engine of a compression ignition type in which portions of an injected fuel spray which have not been evaporated are prevented from striking the walls of the combustion chamber, and the fuel spray is prevented from catching up the air around it when moving in the combustion chamber, thereby providing an engine having reduced combustion noise, reduced amount of smoke and noxious emissions, and improved fuel economy. A combustion chamber is formed in the piston substantially in the form of a spherical cavity gradually narrowing towards the opening of the cavity at the top surface of the piston An air intake mechanism swirls intake air supplied to the combustion chamber. A swirl injector injects a fuel spray substantially in the form of a hollow cone having a velocity component in a direction tangential of the central axis of the nozzle. The nozzle is offset from the central axis of the cavity and inclined with respect to the central axis of the cavity so that the fuel spray is injected in a forward direction of a swirl stream of intake air in the cavity

摘要： A direct injectin type internal combustion engine includes a swirl injector (10) having its port (11) facing a recess (3) formed in a combustion chamber (9). The injector is arranged such that its axis of injection fails to intersect the central axis of the recess (3) but extends at an inclination with respect to the same. In an embodiment typifying the invention, the following relationship is satisfied: in which: D designates the maximum distance between facing sides of said recess (3); wherein with respect to a first transverse plane containing the location of the maximum distance D of said recess and a second plane intersecting said first transverse plane at a right angle, being parallel to the axis of sprays of the swirl injector (10) and containing the center of the recess on the first transverse plane, p designates the distance between the axis of sprays of said swirl injector (10) and a second plane intersecting, at a right angle, a first transverse plane containing the location of the maximum distance D of said recess, said second plane being parallel to the axis of sprays of said swirl injector and containing the center of said recess on said first transverse plane; 6 designates the angle contained between the axis of sprays of said swirl injector (10) and the first transverse plane; and θ s designates the angle of sprays of said swirl injector during fuel injection. The practice of the invention prevents the wall surface of the combustion chamber (9) from being wetted with fuel, thereby improving the combustion phenomena and reducing the specific consumption.
