ABSTRACT:
For 4 cycle internal combustion engines with adjustable inlet control periods and individual suction pipe segments per cylinder or per inlet, at low speeds and high torque (high load up to full load) the combustion sequence is improved in that the opening start of the inlet valve is shifted in such a manner to a later instant following the top dead center of the piston that for a suitable suction pipe length the pressure wave generated while opening the inlet causes a recharging of the cylinder prior to closing the inlet.
