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. As a result, it is possible to increase the degree of constant volume of a fuel-air mixture at the time of combustion and hence to increase thermal efficiency of the internal combustion engine. Furthermore, since a tensile load is applied to a connecting rod in an expansion stroke, it is possible to lower a strength of the connecting rod and hence to reduce the weight thereof as compared with the background art internal combustion engine in which a compressive load is applied to a connecting rod.
