摘要： A combustion chamber structure for an internal combustion engine includes, in a piston top part, a concave portion formed eccentrically with respect to a cylinder center axis, and a tapered portion that connects an upper end face of the piston top part and a side face of the concave portion. The tapered portion is formed so that a tapered portion volume (volume of a space formed between the tapered portion and an upper wall surface of the combustion chamber) in a first portion of the piston top part is greater than a tapered portion volume in a second portion that is nearer than the first portion to an eccentric direction of the concave portion from the cylinder center axis.

摘要： In a diesel engine 1 with fuel injection valves 6a and 6b for injecting fuel 5a, 5b into a combustion chamber 4, respectively, the valves 6a and 6b are arranged such that they are opposed to each other horizontally and diametrically of the combustion chamber 4 in a plan view and are out of alignment in height to each other axially of a cylinder 2. With the valves 6a and 6b being positioned close to and away from the cylinder head 7, respectively, an upper surface of the piston 3 has a rising gradient extending from its side adjacent to the valve 6b toward its side adjacent to the valve 6a up to diametrically halfway of the piston 3.

摘要： On a piston top surface, a cavity and two valve recesses are formed. On the piston top surface, a first heat insulating film is formed. However, on edge portions, a second heat insulating film different from the first heat insulating film is formed. The second heat insulating film is formed along the edge portions. The first heat insulating film is composed of porous alumina and a sealer. The second heat insulating film is composed of only porous alumina.

摘要： In a diesel engine having one inlet valve and one exhaust valve, with an inlet passage having a spiral profile to create rotary air turbulence in a combustion chamber of at least 1.5 times the engine speed, an injector pump, driven by an engine camshaft, supplies high pressure fuel to a fuel injector mounted in the cylinder head, which injects the fuel into the combustion chamber. The injector, which includes a nozzle tip having 4 to 6 jets, is inclined from the axis of the cylinder bore at an angle i of equal to or less than 30 degrees. The injector is also eccentrically mounted from the axis of the cylinder bore at an eccentricity value e that is less than or equal to 0.2 times the bore of the cylinder D. Also, the depth H of the combustion chamber to outer diameter d of the combustion chamber is related by the ratio H/d which is greater than 0.2 but less than 0.5. The centerline of the axis of the combustion chamber is mounted at a distance I from the axis of the cylinder bore in a relationship to the diameter of the bore D by a parimeter I/D which is of equal to or less than 0.1. Adhering to the above design parameters reduces the fuel consumption in small diesel engines with one inlet valve and one exhaust valve.
