Protection of the bottom and basic elements of engines 112 and 113 are presented on illustrations.

The mechanism of a gazoraspredeleniye of petrol engines is presented on an illustration. 3 valves (2 inlet and 1 final) and 2 spark plugs on each cylinder are applied. The special device allows to disconnect management of valves for decrease in fuel consumption (address to materials of Head of the Power supply system and release). The resonant inlet pipeline changes the length for each cylinder separately by means of electronic operated a zaslonok with servo-drivers.
