FIELD: mechanical engineering; transport engineering. ^ SUBSTANCE: invention relates to engine units with internal combustion piston engines designed for operation on automobiles. Proposed engine unit for automobile furnished with brake pedal contains internal combustion piston engine, air cleaner and compressor series-mounted on first main line before engine air intake manifold. Unit is provided with turbine to drive compressor. Turbine is installed on second main line designed for removal of exhaust gases from engine. Unit has also one third main line connected with first main line before compressor input designed for building vacuum in automobile brake system vacuum booster. Throttle valve located between cleaner output and third main line is installed for closing when brake pedal is pressed on. Air throttle valve is provided with electric drive with switch operated by pressure transmitter in automobile brake control hydraulic system. Electric drive is made in form of electromagnet whose core is connected by lever with air throttle valve. ^ EFFECT: improved efficiency of operation of automobile sets employing vacuum, increased economy of engine unit and simplified design. ^ 3 cl, 1 dwg |
