FORCED-IGNITION DIRECT-INJECTION INTERNAL COMBUSTION ENGINE Russian patent published in 2000 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: forced-ignition direct-injection internal combustion engine 1 has intake pipe 14, at least two combustion chambers 5, one intake valve 7 and one exhaust valve 8 in each chamber 5, valve 9 to provide direct injection of fuel into combustion chamber 5, supply channel 16 to at least one intake valve 7 of each combustion chamber 5 along which air controlled by throttling member 36 flows from intake pipe 14. Air can get from system preserving evaporated fuel in fuel tank behind throttling member 36. Delivery of evaporated fuel from preserving system into supply channel 16 is provided only in part of combustion chambers 5, particularly, in single combustion chamber 6 of engine 1. EFFECT: provision of preservation of layer-by-layer state of charge in combustion chambers and during regeneration of adsorption filter. 10 cl, 3 dwg
