Abstract:
An object of the present invention is to provide a novel piston stroke adjustment apparatus for an internal combustion engine that can increase a temperature of an air-fuel mixture during a compression stroke to thus improve and stabilize combustion and also can prevent or cut down a reduction in a temperature of exhaust gas during an expansion stroke at the time of a start of the internal combustion engine. According to one aspect of the present invention, the piston stroke adjustment apparatus increases a mechanical compression ratio during the compression stroke to thus increase the temperature of the air-fuel mixture at a compression top dead center, and reduces a mechanical expansion ratio during the expansion stroke to thus prevent or cut down the reduction in the temperature of the exhaust gas at an expansion bottom dead center, at the time of the start of the internal combustion engine. According to this aspect, the piston stroke adjustment apparatus can increase the temperature of the air-fuel mixture at the compression top dead center to thus improve and stabilize the combustion, and also can prevent or cut down the reduction in the temperature of the exhaust gas at the expansion bottom dead center, at the time of the start of the internal combustion engine. Due to this effect, the piston stroke adjustment apparatus allows the internal combustion engine to improve startability thereof and also reduce an exhaust amount of exhaust harmful components.

Claim (Index 3):
The piston stroke adjustment apparatus for the internal combustion engine according to  claim 1 , wherein the control unit sets the position of the piston at a compression top dead center to a low position relative to the position of the piston at an exhaust top dead center at the time of the start of the internal combustion engine by the piston stroke change mechanism.
