A method of operating a three-stroke internal combustion engine having a cylinder (1) and a piston (2) reciprocable in said cylinder, said piston having a crank rod (3) pivoted to the piston, the opposite end of the crank rod being rotatably mounted to a crank shaft (4) to be rotated under the influence of the reciprocating movement of the piston. The operating cycle of the engine comprises a suction stroke, an expansion stroke and an exhaust stroke. According to the invention, the suction stroke extends over a fraction only of the total stroke of the piston, an instant ignition of the fuel mixture sucked into the cylinder then being effected. The following expansion is effective during the remaining portion of the movement of the piston towards the lower end position in the cylinder. |
