摘要： Between the end of a valve and a valve-operating cam in an internal combustion engine, a valve lifter is inserted. A filler enclosing portion is formed between a shim and the body of the valve lifter. Through an opening from an injector, a filler is introduced into the filler enclosing portion, so that valve clearance is corrected to zero. Differences in valve clearance can be easily corrected.

摘要： An exhaust gas control device is provided in an internal combustion engine. In the device, a valve which comprises a valve head and a valve stem is provided in a body the axis of which is inclined at 45 degrees with respect to a horizontal exhaust pipe. The valve is moved up and down in the body by compressed air and a coil spring. When the valve is engaged on a valve seat in the exhaust pipe, the exhaust pipe is closed, so that exhaust gas flows through a by-pass pipe. When the exhaust pipe is opened, exhaust gas flows through the exhaust pipe, thereby improving engine performance.

摘要： An intake valve in an internal combustion engine comprises a valve stem and a valve head and moves up and down. On either of contact surfaces between the valve stem and a valve guide, annular and elongate grooves are formed to communicate with an intake port at the lower end. Lubricating oil invaded into a gap between the valve stem and the valve guide goes down through the grooves, gets out of the valve guide and adhere onto the valve head in the intake port. The oil on the valve head is washed down by fuel injected from a fuel injector.

摘要： To manufacture an Al alloy tappet in an internal combustion engine, an intermediate which has a circular upper wall and a cylindrical skirt is formed in the first forging step. In the second forging step, a recess is formed on the lower surface of the upper wall. Relatively large-sized metallic structure in the first forging step is finally collapsed, thereby increasing strength and rigidity of the upper wall around the recess.

摘要： A method of manufacturing a tappet used in a valve operating mechanism of a direct acting type in an internal combustion engine. A tip engaged with a center bore of an inner upper surface of a tappet body includes upper and lower convex surfaces and a rounded upper circumferential corner having a certain curvature. thereby preventing concentration of stress even if the tip is subject to high compression load. Thus, durability and reliablity of the tappet are increased.

摘要： A poppet valve moves up and down in a valve operating mechanism in an internal combustion engine. A cylindrical fixed electrode is fixed to a support plate on a cylinder head, and a cylindrical moving electrode is mounted to the lower surface of a valve spring retainer which is mounted to the poppet valve via a cotter. The fixed electrode is connected to a circuit which comprises a variable condenser and a resistance. The valve moves up and down during firing operation of the engine. Thus, variation in electrostatic capacity is detected by the two electrodes, transmitted to a circuit via a lead mounted to the fixed electrode, and converted to a voltage by the circuit, thereby detecting valve position exactly.

摘要： A soldering layer is formed on a valve guide or valve seat and/or a holding bore of a cylinder head in an internal combustion engine. The solder can be melted below the highest temperature which the valve guide or valve seat reaches during operation of the internal combustion engine. The valve guide or valve seat is a press fit in the holding bore of the cylinder head, and with operation of the internal combustion engine, the soldering layer is melted to close gaps on the contacting surfaces between the holding bore and valve guide or valve seat. The soldering layer finally has a higher melting point than the highest temperature of the valve guide or valve seat as above. During operation of the engine, the soldering layer is not melted.
