摘要： A two-stroke engine comprising three exhaust valves and two intake valves. These exhaust valves and these intake valves are arranged on the peripheral portion of the inner wall of the cylinder head, and one additional intake valve is arranged on the central portion of the inner wall of the cylinder head. The valve openings of the three intake valves, which are located on the exhaust valves side, are masked by the masking walls. The central portion of the combustion chamber is scavenged by the fresh air fed from the additional intake valve, and the peripheral portion of the combustion chamber is scavenged by the fresh air fed from the remaining two intake valves.

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.

摘要： A guideway transit system which can reduce a scale of an infrastructure while maintaining ride comfort for passengers of a vehicle is provided. The guideway transit system includes a noncontact vehicle guiding system and a contact vehicle guiding system. The noncontact vehicle guiding system detects information relating to a lateral position of a vehicle on a road and steers the vehicle to move along a predetermined path on the road based on the detected information. The contact vehicle guiding system which restricts a lateral position of the vehicle by a contact between a guide wheel which laterally projects from the vehicle and a guide wall provided on a side of the road. The guideway transit system further includes a controller which prohibits steering of the vehicle by the noncontact vehicle guiding system when a lateral position of the vehicle is restricted by the contact vehicle guiding system. An automated vehicle which is used in the guideway transit system is also provided.

摘要： A fuel injector comprising a needle valve and a stop member cooperating with the needle valve. The stop member selectively controls the maximum amount of lift of the needle valve to provide a smaller maximum lift or a larger maximum lift thereof whereby, when the required amount of fuel to be injected by the fuel injector is small, the needle valve is lifted to the smaller maximum lift, and when the required amount of fuel is large, the needle valve is lifted to the larger maximum lift.

摘要： Disclosed is a method of igniting in an internal combustion engine comprising a main combustion chamber and an auxiliary combustion chamber which are interconnected to each other by a connecting passage. The spark gap of the spark plug is located in the connecting passage. A ratio of the volume of the auxiliary combustion chamber to the cross-sectional area of the connecting passage is set in the range of 5 through 15 cm for creating a strong swirl motion of the combustible mixture in the auxiliary combustion chamber at the time of the compression stroke. The length of the continuance time of the discharging arc is set at approximately 1 m sec.
