FIELD: engines and pumps.
SUBSTANCE: in idling and at low load, to prepare fuel-air mix, portion of intake cold air is heated by exhaust gas and mixed with intake cold air. Proposed method is implemented in ICE with cold air pipeline 10 accommodating engine throttle 11 while hot air pipeline 12 accommodates throttle 13. Said hot air pipeline 12 is fitted in outlet pipeline 14. In the latter, cold air is heated by exhaust gases. The above arrangement allows improving filling of operating cylinders due to reduced throttling of intake pipeline.
EFFECT: higher efficiency in connecting and disconnecting cylinders.
