    摘要： A cylinder cooling system for aircraft engines is disclosed in which an air intake leads to multiple air chambers and the air is divided among the air chambers, which lead to the cylinders of the engine. In this way, approximately equal amounts of air of approximately the same temperature are able to pass over each cylinder, thereby providing more even cooling, resulting in more efficient engine performance. In addition, the cylinder cooling system is easily removable to access the engine spark plugs and fuel injectors for inspection and routine maintenance while not requiring the spark plug wiring or fuel lines to be disassembled in any way.

    摘要： In a single-cylinder internal combustion engine fitted with a knock sensor, a temperature increase of the knock sensor is suppressed and prevented and the reliability of the knock sensor is improved. The engine includes a crankcase accommodating a crankshaft, a cylinder block connected to the crankcase and including a cylinder provided therein, a cylinder head connected to the cylinder block, a sensor mounting boss provided on the cylinder block, a knock sensor arranged to detect knocking and mounted to the boss, a fan to guide air to at least the sensor mounting boss, and an air shroud.

    摘要： A combustion-type power tool includes a cylinder and a combustion chamber frame disposed to surround the cylinder and movable along the cylinder. A combustion chamber is formed on top of the cylinder that accommodates a gaseous mixture of existing air in the combustion chamber and fuel injected therein from a gas cylinder. A spark plug generates a spark to combust the gaseous mixture in the combustion chamber. A trigger switch produces the spark in the spark plug when operated. A piston slidably moves along the inner surface of the cylinder and driven by combustion in the combustion chamber. A driving blade is secured to the piston for driving a fastener. A partition wall divides the inner space of the outer frame into a first space in which the cylinder and the combustion chamber frame are disposed and a second space in which the gas cylinder is disposed. The partition wall is formed with a through-hole through which the first space and the second space are in fluid communication with each other. A plurality of ribs is formed on the outer surface of the cylinder for regulating an exhaust gas flow generated by combustion of the gaseous mixture in the combustion chamber. With the ribs, the exhaust gas discharged from the combustion chamber is not directed toward the through-hole, thereby preventing the gas container from heating up.

    摘要： A small four cycle internal combustion engine is disclosed having a cylinder head assembly which comprises a cylinder head cooperating with a cylinder block of the engine, and a rocker box connected to the cylinder head so as to define an air passage therebetween through which air may pass. The cylinder head has cooling fins projecting into the air passage between the cylinder head and the rocker box and aligned generally transversely to a line extending between the axes of the intake and exhaust valves. The air passage preferably extends between an intake port and an exhaust port of the engine, and above an exhaust gas recirculation port extending between the intake and exhaust ports. A pair of push rod tubes are integral with the rocker box and extend between the rocker box and a crankcase of the engine externally of the cylinder block. The engine of the present invention also includes a cam tower assembly comprising a base member and a pair of parallel shafts extending from the base member. One of the shafts functions as a camshaft and has a unitary cam gear and cam rotatably supported thereon. The other shaft is a follower shaft and has a pair of cam followers rotatably supported thereon.
