FIELD: engine engineering. SUBSTANCE: engine has inlet system, lubricating system, system for ventilation of the crankcase, and resonator connected to the path of the inlet system. The resonator for silencing exhaust is a standard above-valve space which is enclosed with a cover of the cylinder head. The supporting member of the air cleaner is made up as a rigid branch pipe which is mounted in the bottom by way of the sealing member. The oil filling neck is mounted on the cover of the air cooler coaxially to the supporting branch pipe to define telescopic connection with the latter.
