摘要： In an internal combustion engine, an injection hole is provided in the cylinder head to inject narrow streams of air towards the spark gap, particularly during idling and low load running conditions. The injected air is 5 to 30% by weight of the intake fuel-air mixture provided via the intake manifold and creates a swirl or turbulence thereby increasing combustibility. The hole is connected via a sub intake passage to the main air intake passage upstream of the venturi in the carburetor or between the venturi and throttle valve.

摘要： In a combustion chamber structure in a direct injection type diesel engine, in order to prevent flames from flowing out to a quench zone Q from a combustion chamber (32) which opens to a top part (30a) of a piston (30) to thereby prevent cooling of the flames and also in order to prevent a fuel spray from being concentrated on a lower portion of the combustion chamber (32), the fuel spray should be reflected in the combustion chamber (32) effectively according to displacement of the piston (30) to allow it to be mixed with air sufficiently in the combustion chamber (32) or in a cylinder (28), and to this end there are provided a guide wall (34) which becomes larger in inside diameter downwardly from an opening edge portion (33) of the combustion chamber (32), as well as fuel reflection walls (36, 38) which project below the guide wall (34) toward a central axis (lo) of the combustion chamber (32) and divide the combustion chamber vertically into a first combustion chamber (44) and a second combustion chamber (48).

摘要： In a multi-cylinder internal combustion engine having a plurality of cylinders which are supplied with air via one common throttle valve and a control unit for regulating the number of operating cylinders to rest an arbitrary number of cylinders by blocking the air supply to said cylinders, the output of the engine under Z.sub.1 -cylinder operation is known to come to coincide with the output under Z.sub.2 -cylinder operation at one point with the same degree of opening of the throttle valve under a given constant rate of the engine rotation. At such a point, the pressure of the intake manifold under both the Z.sub.1 -cylinder operation and the Z.sub.2 -cylinder operation remain at or close to a certain value respectively over a wider range of rotation of the engine. This multi-cylinder internal combustion engine enables smooth switching between the Z.sub.1 -cylinder operation and the Z.sub.2 -cylinder operation without causing fluctuation in output nor shock by detecting the pressure at the intake manifold and the control unit for such switching can be made simple in construction.

摘要： In a multi-cylinder internal combustion engine having a plurality of cylinders which are supplied with air via one common throttle valve and a control unit for regulating the number of operating cylinders which suspends the operation of an arbitrary number of cylinders by intercepting the air supply to said cylinders, it is noted at a point the output of the engine under Z.sub.1 -cylinder operation coincides with the output under Z.sub.2 -cylinder operation at the same degree of opening of the throttle valve at a given constant rate of engine rotation. Based on such a fact, the multi-cylinder internal combustion engine is made capable of shifting to and from Z.sub.1 -cylinder operation and Z.sub.2 -cylinder operation in the proximity of said point where these outputs coincide. This way, there will be no fluctuation in the output nor shock at the time of switching, and the control unit for this purpose can be made simple in construction.

摘要： An internal combustion engine has a combustion chamber which communicates via an injection port with an injection chamber whose volume is 0.5 cc.about.1.5 cc. During the intake stroke, air-fuel mixture is introduced from an intake port into the combustion chamber, and at the same time, under the influence of high vacuum produced in the combustion chamber, a jet stream of exhaust gas, air or air-fuel mixture is violently injected from the injection port into the combustion chamber via an auxiliary intake passage communicates with the injection chamber through an auxiliary intake valve, so that the jet stream enhances the ignitability by scavenging burned gases from around a spark gap and also generates strong swirl and turbulence of air-fuel mixture in the combustion chamber.
