摘要： A two-stroke engine comprising a spark plug arranged at the center of the inner wall of the cylinder head, and a fuel injector arranged on the periphery of the inner wall of the cylinder head. A depression extending from the point beneath the spark plug to the point beneath the tip portion of the fuel injector is formed on the top face of the piston. When the engine is operating under a light load, fuel is injected by the fuel injector only once toward the depression, and conversely, when the engine is operating under an intermediate load, fuel is injected twice. Namely, a first injection is carried out when the piston is at a lower position, and a second injection is carried out when the piston is at a higher position, to thus direct fuel toward the depression.

摘要： An internal combustion engine comprising a spark plug arranged at the center of the inner wall of the cylinder head, and a fuel injector arranged on the periphery of the inner wall of the cylinder head. A depression is formed on the top face of the piston. This depression is defined by a flat bottom wall and a pair of extended straight side walls which diverge toward the fuel injector side. Fuel is obliquely injected on the flat bottom wall of the depression from the fuel injector.

摘要： An internal combustion engine comprising a spark plug arranged at the center of the inner wall of the cylinder head, and a fuel injector arranged on the periphery of the inner wall of the cylinder head. A depression extending from the position beneath the spark plug to the position beneath the tip portion of the fuel injector is formed on the top face of the piston, and fuel is injected toward the depression. When the engine is operating under a heavy load, the fuel moving along the axis of injection impinges upon the concaved inner wall of the depression at substantially a right angle. When the engine is operating under a light load, the injection time is retarded, and at this time, the fuel moving along the axis of injection impinges upon the concaved inner wall of the depression at an acute angle.

摘要： A two-stroke engine including a pair of intake valves. A masking wall is provided for each intake valve to mask the valve opening between the valve seat and the peripheral portion of the intake valve, which is located on the exhaust valve side, for the entire time for which the intake valve is open. The exhaust valves open earlier than the intake valves, and the exhaust valves and the intake valves are closed at substantially the same time.

摘要： An internal combustion engine having an air blast valve which injects fuel together with pressurized air in the form of a conical shaped spray of fuel. A depression is formed on the top face of the piston, and the conical shaped spray of fuel is injected from the air blast valve toward the depression. The longitudinal width of the depression in the moving direction of the spray of fuel is larger than the transverse width of the depression in the direction perpendicular to the moving direction of the spray of fuel, and the opposing side walls of the depression, which define the transverse width of the depression, are positioned slightly outward from the side face of the conical shaped spray of fuel.

摘要： An apparatus for controlling valve timing in an internal-combustion engine. The apparatus includes a pair of sleeves inserted into each other. One of the sleeves is connected to the camshaft and the other sleeve is connected to a timing pulley which is connected to the crankshaft. One of the sleeves has diametrically opposed slits and the other sleeve has diametrically opposed slits located adjacent to the corresponding slits in the first sleeve. Abutment rollers are arranged in the slits and are mounted on an axially slidable slider. Movement of the slider causes the generation of an angular displacement between the sleeves, resulting in variable valve timing. A bearing unit is arranged between the inner and the outer sleeves.

The engine comprises a first raised portion formed on the inner wall of the cylinder head, a second raised portion formed on the top face of the piston at a position opposite to the first raised portion with respect to the axis of the piston, and a third raised portion formed on the inner wall of the cylinder head above the second raised portion. A first flat squish area is formed between the flat peripheral top face of the piston and the flat bottom face of the first raised portion. A second spherical shell shape squish area is formed between the spherical bottom wall of the third raised portion and the spherical rear face of the second raised portion. A recessed portion is formed on the top wall of the main combustion chamber at a position near the first raised portion. The open end of the connecting passage is arranged in the recessed portion. The spark plug is arranged within the recessed portion at a position near the open end of the connecting passage and outside of the extension of the connecting passage.

摘要： An apparatus for controlling valve timing in an internal-combustion engine. The apparatus includes a pair of telescoping sleeve members. One of the sleeve members is connected to the camshaft of the engine with a bolt, and the other sleeve member is connected to a timing pulley which is connected to the crankshaft of the engine. Each of the sleeve members has at least one slit which is located adjacent to a slit on the other sleeve member. The adjacent slits are angled relative to each other. Abutment rollers are arranged in the slits and are mounted on an axially movable member. The movable member is connected via a screw mechanism to a rotary motor. The rotational movement of the output shaft of the motor is changed to a linear movement of the support member, thereby causing the support member to move, which movement, in turn, causes the generation of angular displacement between the sleeve members so that variable valve-timing is obtained. The output shaft is hollow and is, on the inner end thereof, open to the head portion of the bolt. The other end of the shaft is closed with a plug.

摘要： An apparatus for controlling valve timing in an internal-combustion engine. The apparatus includes a pair of coaxial sleeves, one inserted into the other. One of the sleeves is connected to a camshaft of the engine, and the other sleeve is connected to a timing pulley which is connected to the crankshaft of the engine. One of the sleeves has diametrically opposite slits while the other sleeve has diametrically opposite slits located adjacent to the respective slits in the one sleeve. The adjacent slits are skewed with respect to each other. Roller-bearing units are arranged in the slits and are mounted on an axially slidable slider. The slider is connected via a screw mechanism to a rotary motor. The rotational movement of the motor is changed to a linear movement of the slider, thereby causing the slider to move, which movement, in turn, causes the generation of angular displacement between the sleeves so as to obtain a variable valve timing.
