GASOLINE TURBO CHARGER VEHICLE HAVING ENGINE COOLING SYSTEM CONNECTED TURBO CHARGER AND CONTROL METHOD THEREOF

A gasoline turbocharger vehicle of the present invention comprises: a turbo inlet line (50A) through which engine cooling water is supplied to cool a turbocharger (50-1); a turbo outlet line (50B) connected to a turbo cooler (50-2) in which hot turbo cooling water heated as a heat source of the turbocharger (50-1) is discharged and circulated; and a turbo cooling water line (50A, 50B, 50C) made of a turbo reservoir line (50C) connected between the turbo cooler (50-2) and a reservoir (20-1). Accordingly, in spite of turning off the engine after a high load drive, a formation of a high temperature heat source of the turbocharger (50-1), which causes the engine cooling water to boil, is prevented. 본 발명의 가솔린 터보차저 차량에는 터보차저(Turbo Charger)(50-1)를 냉각하도록 엔진냉각수가 공급되는 터보인렛라인(50A), 상기 터보차저(Turbo Charger)(50-1)의 열원으로 가열된 고온 터보냉각수가 빠져나와 순환되는 터보 쿨러(50-2)에 연결된 터보아웃렛라인(50B), 상기 터보 쿨러(50-2)에서 나와 리저버(20-1)로 연결된 터보리저버라인(50C)으로 이루어진 터보냉각수라인(50A,50B,50C)이 포함됨으로써 고 부하 주행 후 시동 오프(Off)가 이루어지더라도 엔진 냉각수를 끓게 하는 터보차저(Turbo Charger)(50-1)의 고온 열원 형성이 방지되는 특징을 갖는다.
