摘要： A piston slidably fitted in a cylinder is connected to an auxiliary piston slidably fitted in an auxiliary cylinder coaxial with the cylinder through a first connecting rod. The left and right crankshaft halves are disposed outside of a piston sliding range of the cylinder with respect to the radial direction thereof. The increase of the volume of a combustion chamber corresponding to the increase of the crank angle with reference to top dead center of the piston is suppressed, and it is therefore possible to enhance the equal volume degree at the time of combustion of a mixture gas and to enhance thermal efficiency. This arrangement also enhances thermal efficiency, and simplifies the structures of intake systems and valve mechanisms when employed in horizontally opposed type internal combustion engine.

摘要： To increase thermal efficiency by increasing the degree of constant volume of a fuel-air mixture at the time of combustion in an internal combustion engine. In an internal combustion engine, a piston slidably fitted in a cylinder is connected to a crankshaft via a connecting rod, and a cylinder head in which a combustion chamber is defined is disposed between the piston and the crankshaft. As compared with a background art internal combustion engine in which a combustion chamber is disposed opposite to a crankshaft with a piston located therebetween, a ratio of an increased amount of the volume of the combustion chamber to an increased amount of a crank angle of the piston from the top dead center position can be suppressed at a small value.

摘要： Three intake and two exhaust valves are arranged on a single circumferential line around the center of the combustion chamber with the longitudinal axes of the valves crossing at a single point on the longitudinal axis of the cylinder. An ignition plug is provided in the space between the two exhaust valves and is angled so that its forward end is directed towards the center of the combustion chamber. A single common cam shaft is provided horizontally at an intermediate position of the cylinder head between the intake valves and the exhaust valves.

摘要： A nutless type connecting rod of high mass production efficiency is provided. A large end section of a connecting rod is divided into a body side and a cap section, which are subjected to surface hardening treatment. Then the surface-hardened layer formed on a division face of the body side is removed. Thereafter, a female threaded hole is formed through the division face into the thickness of the body.
