Abstract
A diesel internal combustion engine with several cylinder units each consisting of a piston and a cylinder, with a low compression ratio and with exhaust gas turbocharging, in which for purposes of starting, a number of the cylinder units operate as internal combustion engine and a number as compressor during the compression stroke; one compressor cylinder unit each is thereby coordinated to a corresponding engine cylinder unit, whereby the piston of compressor unit leads the piston of the engine cylinder unit to such an extent that the engine cylinder unit at the beginning of its compression stroke can be supercharged by the compressor cylinder unit; the cylinders of the two cylinder units are connected with each other by way of a line separate from the customary suction and exhaust gas lines, by way of a first valve controlled corresponding to the operating condition of the internal combustion engine and by way of a second valve which opens in the presence of the necessary supercharging pressure.
