To provide a method to start an internal combustion engine without the drag torque, and without the need to install an additional pressure reducing valve, in the method starting an internal combustion engine, especially starting the internal combustion engine without a starter.
This is a method to start the internal combustion engine (2) without the starter, especially, a hybrid drive system (1), wherein a part of a cylinder (21) of the internal combustion engine (2) is composed as a cylinder that can decompress. The method by which the cylinder can be decompressed by the compression stroke includes: a step to adjust the final position of a crankshaft (25) when the internal combustion engine (2) stops and locates the cylinder that can be decompressed at the final position when stops in the compression stroke; and a step to decompress the cylinder that locates in the compression stroke and can be the decompressed when the start process is demanded following stop of the internal combustion engine (2) by firing the air and the fuel mixture in the cylinder (21) of the internal combustion engine (2) located in the combustion cycle in the static condition and generating the torque to start the internal combustion engine (2).
