    摘要： A control device is provided for an engine in which premixed compression ignition combustion is carried out. The device includes an air amount adjusting mechanism, a variable valve mechanism, an exhaust choke valve, a water temperature sensor, and a processor. The processor controls the variable valve mechanism so that a valve overlap period of a given amount or more is formed in a low-load range where the engine load is low, and controls an injector, the air amount adjusting mechanism, and the exhaust choke valve so that A/F lean mixture gas is formed inside a combustion chamber, and premixed compression ignition combustion of the mixture gas is carried out. During the operation in the low-load range, the combustion controlling module makes an opening of the exhaust choke valve when a temperature parameter is low, smaller than that when the temperature parameter is high.

    摘要： A fuel injection unit for assembly to a cylinder head and for injecting first and second fuel to a cylinder of an internal combustion piston engine includes a first fuel feeding section, a second fuel feeding section, a pressure accumulator in the first fuel feeding section, and a flow fuse arranged in the first fuel feeding section between the pressure accumulator and a fuel injection valve of the first fuel feeding section. The fuel injection valve includes a fuel handling section and control section, and the control section is a hydraulic control section fluidly separated from the fuel handling section.

    摘要： An internal combustion engine for use with a propeller driven aircraft includes a camshaft adapted to function as an output shaft that rotates a propeller to provide propulsive thrust. A gear set is configured to transfer rotational power from the crankshaft to the camshaft and to rotate the camshaft at a velocity that is proportional to the rotational velocity of the crankshaft. The gear set is disposed rearward of the engine housing rearward wall and is configured to rotate the camshaft in a direction opposite the crankshaft rotation. The length of the camshaft reduces engine torsional vibration. In one embodiment, the engine is a six-cylinder compression ignition engine having a boxer configuration and can generate a peak output power within a range from about 300 horsepower to about 350 horsepower.

    摘要： A uniflow two-stroke engine includes: a cylinder receiving a piston such that the piston can reciprocate therein and defining a combustion chamber above the piston; an exhaust port having one end in communication with an upper end portion of the cylinder; a scavenging port having a scavenging orifice at one end, the scavenging orifice being in communication with a lower part of a side portion of the cylinder such that the scavenging port is selectively brought into communication with and shut off from the combustion chamber by the piston; and an exhaust gas recirculation passage having one end in communication with a part of the side portion of the cylinder above the scavenging port and the other end in communication with the scavenging port such that the exhaust gas recirculation passage is selectively brought into communication with and shut off from the combustion chamber by the piston.

    摘要： The present invention is a compression-ignition direct-injection internal-combustion engine comprising at least a cylinder (10), a cylinder head (12) carrying fuel injection means (14), a piston (16) sliding in the cylinder, a combustion chamber (34) limited on one side by an upper face (44) of the piston comprising a projection (48) extending in the direction of the cylinder head and located in a centre of a concave bowl (46). The engine comprises injection means projecting fuel in at least two fuel jet sheets with different sheet angles (A1, A2), a lower sheet (36) of jet axis C1 and an upper sheet (38) of jet axis C2, and at least two mixing zones (Z1, Z2) of the combustion chamber. One of the zones comprises a toroidal volume (64) having center B with a flat bottom (56) into which fuel jets (40) of the lower sheet are injected so that axis C1 of the lower sheet jets is contained between center B and projection (48).
