摘要： A position detector for detecting the piston TDC position in a piston engine has a cylindrical casing penetrating the top wall defining a combustion chamber of the engine and fixed thereto, a light emission element, a light reception element each being accommodated within the upper half of the casing, an inlet optical fiber connected to the light emission element and an outlet optical fiber connected to the light reception element. These optical fibers are inserted into the lower half of the casing. The lower end of each optical fiber is opposed to the upper surface of the piston at a predetermined distance therefrom when the piston is located in the vicinity of the TDC position. The light emitted by the light emission element is applied to the upper surface of the piston, after passing the inlet optical fiber. The reflected light from the upper surface of the piston is received and sent to the light reception element by the outlet optical fiber. The light reception element transmits a light reception signal corresponding to the amount of the received light to the detecting circuit. The detecting circuit detects peaks of the light reception signal, which appear before and after the piston TDC position, calculates the half of the rotating angle of a crankshaft between two adjacent peaks and transmits a TDC piston detecting signal when the crankshaft rotates by the calculated rotating angle from the time the preceding peak out of two adjacent peaks appearing in the following period is detected.

摘要： A multi-cylinder internal combustion engine having a plurality of cylinders, each comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The accumulation chambers are interconnected to each other via a common connecting passage. The opening operation of the accumulation valve is controlled so that the accumulation valve remains opened during the compression stroke. In the first half of the compression stroke, a jet of the combustible mixture is spouted out into the combustion chamber from the accumulation chamber to create a strong swirl motion in the combustion chamber. In the latter half of the compression stroke, the combustible mixture in the combustion chamber flows into the accumulation chamber to accumulate the combustible mixture under high pressure, which is spouted out into the combustion chamber at the next cycle.

摘要： An internal combustion engine is provided with an auxiliary piston reciprocating within an auxiliary chamber for generating turbulence in a gas mixture contained within a main combustion chamber. Forward motion of the auxiliary piston causes the injection of a gas into the main combustion chamber through a communicating passageway when the main piston approaches top dead center of the compression stroke.

摘要： In a carburetor, a branch passage is connected to the fuel-air mixture passage for charging exhaust gases back into the fuel-air mixture. A control valve is positioned in the branch passage for regulating flow of the exhaust gases and a first spring biases the control valve into the closed position. A throttle valve in the fuel-air mixture passage is operatively coupled to the control valve by a linkage arrangement so that the two valves can be operated together. The linkage arrangement includes a second spring which permits movement of the throttle valve without corresponding movement of the control valve. Further, the linking arrangement provides a certain amount of play between the movement of the throttle valve and the control valve so that the operation of the control valve can be delayed relative to the opening movement of the throttle valve.

摘要： In an carburetor where a shaft is positioned within a bearing section and there is no lubricant, such as oil or water, used between the shaft and bearing section, a flow of pressurized air is directed through a passageway into the bearing section and then into a slot which extends in the circumferential direction so that air can be directed axially between the shaft and the bearing section. The flow of air prevents the entry of any alien substances, such as dust or moisture, into the space between the shaft and the bearing section.
