The engine comprises three cylinders (2) radially attached to the casing of the crankcase (1). Each cylinder (2) is closed from above with the head (3) with the ignition plug (4) situated in it, whereas from below it is closed with the sealed partition (5). What is more, there is the inlet channel (6) brought to the cylinder (2) as well as the outlet channel (7) is led out, and also rinsing channels (9). In the middle of the partition (5) of each cylinder (2) the linear slide bearing (10) is embedded, which is equipped with the sealing elements (12) from below. Through the slide bearing (10) the push rod (12) is led in the form of the grinded shaft, whose upper end is connected with the piston (8), whereas its lower end is connected with the articulated connecting-rod (13). The articulated connecting-rod (13) is connected with the crankshaft (15) equipped with the counterweight (14) via the piston pin (16) assigned to it in the intermediary disk (17), which is embedded on the crank throw of the crankshaft (15). In the first variant of the invention in the head (3) of the cylinder (2) the injector (18) is mounted, whereas in the second variant to the inlet channel (7) of the cylinder (2) the carburetor (G) is connected, to which the fan (W) is connected.
