摘要： A control device of a gasoline direct-injection engine is provided. The control device includes an engine body, an injector, and a controller. Within a high load operating range, the controller causes the injector to perform a pre-injection and a post injection. In the pre-injection, the fuel is injected to cause a fuel concentration within an in-cylinder radially peripheral section to be higher than a fuel concentration within an in-cylinder radially central section at a timing for the fuel to ignite. In the post injection, the fuel is injected to cause the fuel concentration within the radially central section to be higher than the fuel concentration within the radially peripheral section at a timing for the fuel to ignite. The timing for the fuel injected in the post injection to ignite is after an oxidative reaction of the fuel injected in the pre-injection occurs and after a compression top dead center.

摘要： An engine having improved combustion characteristics is provided. The engine includes a fuel injection system that is variable between two operational states. In the first operating state, the fuel injectors provide a fuel spray having first spray pattern characteristics. When the system detects that an operation characteristic exceeds a threshold, the fuel injectors are displaced into a second operating state. In the second operating state, the fuel injectors provide a spray pattern having first spray pattern characteristics. The combustion cycle may be characterized by timing the fuel injection so that the fuel is sprayed into the cylinder early in the compression stroke. Further still, the combustion cycle may be characterized by controlling the fuel pressure so that the fuel pressure is inversely related to the load on the engine.

A swirl chamber is formed in a piston, and a primary chamber by a combustion chamber structure provided in a cavity of a cylinder head. A fuel injection nozzle injects a low evaporativity fuel, such as heavy oil, into the cylinder at the beginning of a compression stroke, disperses the fuel into an air swirl in the cylinder, forms a uniform gaseous mixture of the fuel and air therein, and ignites and burns with the assistance of a glow plug the gaseous mixture entering the swirl chamber through communication ports at the end of the compression stroke. In another embodiment, the piston is provided with a plurality of radially arranged communication ports and a downwardly convergent fuel injection port, and a fuel injection nozzle injects a low evaporativity fuel into a cylinder at the beginning of a compression stroke, disperses the fuel into an air swirl in the cylinder, forms a uniform gaseous mixture of the fuel and air in the cylinder, and ignites and burns the gaseous mixture in the swirl chamber by reliably supplying an ignition fuel thereto through the fuel injection port at the terminal end of the compression stroke.

摘要： A combustion apparatus and a combustion system for an internal combustion engine wherein a funnel-shaped cone with an orifice at the apex thereof is provided in a combustion chamber and spaced from an ignition apparatus so that as a gaseous, combustible mixture is introduced into the chamber, it flows through the cone to the orifice where it is ignited by the ignition apparatus so that the flame caused thereby explodes outwardly through ejection openings and along the external surface of the cone into the chamber so as to envelope the uncombusted gases and cause maximum explosion and combustion of the mixture automatically. The structure is applicable to existing conventional spark ignition engines when the cone is provided at the front end portion of the spark plug. For compression ignition engines, the cone is provided in a pre-combustion chamber in the cylinder head or is attached to the cylinder head and extends into a chamber provided in the piston. In continuous-flow internal combustion engines, the cone is provided within the combustion chamber, first combustion being made outside of the cone and subsequent combustion being made inside of the cone.

摘要： A piston is manufactured by incorporating a reinforcement which is formed at least in part by a fibre material and which is so non-uniform as to provide differing characteristics in the cast piston in predetermined differing regions of the piston. For example, the volumetric density of the fibres may be different in one region of the reinforcement as compared with another region in order to produce a more resistant region in the cast piston. Additionally or alternatively, the reinforcement may hold finely divided materials which combine with the piston material during casting to give improved properties. Examples of this are the incorporation of particles of silicon, silicon carbide or silicon nitride to improve wear and/or the incorporation of molybdenum disulphide and tungsten disulphide or graphite to improve lubrication.

摘要： An internal combustion engine comprising a piston (1) having a recessed combustion bowl (3) with a raised projection (4) in the floor of the bowl so as to define an annulus with the sides of the bowl, swirl means to cause the inlet air to rotate about said raised projection, and a fuel injector (2) having orifices that spray a plurality of jets into the annulus at spaced points around the projection (4), the cross-sectional area of the annulus being such as to vary around the projection (4) and to have a minimum value in a median plane (D--D) through the axis (C) of the projection (4), and the injector nozzle (2) being located in a central region of the bowl (3) and having orifices orientated so as to direct jets of fuel both sides of said median plane. The cross-section area of the annulus is varied by varying the radial width of the annulus, this being achieved conveniently in a circular bowl by offsetting the axis (C) of the projection (4) radially from the axis of the bowl (A). Both axes then lie on the median plane (D--D) through the narrowest part of the annulus. The injector nozzle (2) is also located along the median plane (D--D) and directs fuel jets into the four quadrants of the annulus defined by the median plane (D--D) and perpendicular plane (E--E) through the axis (A) of the bowl (3).
