摘要： In a heat-insulating swirl chamber engine, subsidiary fuel is injected from subsidiary nozzles along the inner wall surfaces of swirl chambers of a heat-insulating structure from the second half of an intake stroke to the first half of a compression stroke, so that a lean mixture formed in the swirl chambers does not diffuse into cylinders, deterioration of hydrocarbon components can be prevented and moreover, since the fuel comes into contact with the wall surfaces of the swirl chambers, heat energy can be recovered from the wall surfaces. Next, main fuel is injected from main nozzles into the swirl chambers from the second half of the compression stroke to the first half of an expansion stroke, so that the inside of the swirl chambers becomes fuel-rich due to the lean mixture formed in advance in the swirl chambers and the fuel by the main injection, combustion is effected in the fuel-rich state to restrict the generation of NOx and moreover, cycle efficiency can be improved because the main combustion period is shortened.

摘要： A swirl chamber is defined by an approximately spherical cavity formed in a cylinder head of an internal combustion engine with the radius of the swirl chamber being reduced in the direction the swirl flows in the swirl chamber. Therefore, the swirl is accelerated as it flows in the swirl chamber. The swirl chamber communicates with a main combustion chamber formed in a piston top via a passage formed in the cylinder head when the piston is at top dead center, and air in the main combustion chamber is forced into the swirl chamber due to the compression stroke of the piston. The passage is formed in a manner such that it has constant transverse section lengthwise and such that a part of the passage defines a tangential line of the swirl chamber. Therefore, the air forced into the swirl chamber passes through the passage with little friction loss, smoothly enters the swirl chamber and gains velocity in the swirl chamber.

摘要： A piston crown is formed with cavity a which includes a first flame deflecting member which divides the flame ejected from a transfer port interconnecting a swirl chamber with a main combustion chamber while the piston is relatively close to its TDC position and a second flame deflecting arrangement which divides the flame flow after the piston has descended by a given amount. The stage deflections of the flame promotes extensive dispersion thereof and the formation of a flame plume which engulfs a relatively large amount of the air in the combustion chamber and improves mixing of the burning gases and unburnt fuel with the air in the combustion chamber.

摘要： In a valve-controlled compression-ignition engine with direct fuel injection and an intake passage inducing the inflowing air to rotate around the cylinder axis, an ideal combustion system has been found, combining the advantages of a diesel engine with direct fuel injection and an open combustion recess and those of a diesel engine with a pre-combustion or swirl chamber, while eliminating the main disadvantages of these two basic types. According to the proposals put forward by this invention the restricted passage or throat in the center area of the combustion chamber is bounded by means of a rotationally symmetric center part, whose lower end forms part of the toroidal combustion chamber, and whose top remains slightly below the fuel jet at the upper dead center of the piston, and which constitutes the inner boundary of the narrow ring-shaped scavenge passage leading from the combustion recess to the cylindrical throat, or rather to the cylinder itself.

摘要： In order to promote a good flame dispersion within the combustion chamber of a swirl chamber type Diesel engine, a shaped recess formed in the piston crown is arranged to have a trench portion into which the flame from the swirl chamber is injected and mirror image flame dispersion portions on either side of the trench which terminates at the periphery of the piston crown. This arrangement inhibits the formation of secondary flame flows which tend impede desirable patterns within the flame disportion portions and simultaneously enlarges the dispersion area. In addition, careful selection of the dimensions of the transfer port which interconnects the swirl chamber and the main combustion chamber, and the various sections of the shaped recess, promotes further reductions in HC and smoke emissions.

摘要： A direct injection type internal combustion engine has a piston reciprocatably fitted in the bore of a cylinder block defining a combustion chamber together with the cylinder block and a cylinder head. A main recess is formed in the combustion chamber for accelerating the swirl of intake air which is prepared and introduced by an intake device. At least one auxiliary recess is formed in the main recess and is arranged in the direction of the intake air swirl and in the direction of the fuel injection of a fuel injector for generating a secondary swirl different from the intake air swirl and for generating turbulence between the two swirls. Thus, the introduction of air into the fuel droplets fed from the fuel injector is promoted by the intake air swirl and the secondary swirl so that the combustion efficiency of the internal combustion engine is improved.

摘要： A combustion device for an internal combustion engine which includes a cylinder, a head closing one end of the cylinder, and a piston reciprocable in the cylinder. The head and piston have stepped portions adapted to interfit as the piston approaches the head so as to define a compression chamber and a combustion chamber of greater volume than the compression chamber, for receiving a fuel charge, and a restricted passage between the combustion chamber and the compression chamber. The head and piston are shaped and the device is otherwise provided with structure so that as the piston approaches dead center, a portion of the charge compressed in the compression chamber combusts spreading combustion gases and flame through the restricted passage so as to immediately thereafter cause swirling of, and ignite the portion of the charge in, the gases in the combustion chamber.
