EXHAUST MANIFOLD TO SUPPLEMENT ENGINE PERFORMANCE

摘要

The present invention relates to an exhaust manifold of an engine and, more specifically, to an exhaust manifold to supplement a performance of an engine. The exhaust manifold includes a sub-pressure adjusting unit capable of adjusting the pressure of an exhaust gas included in the exhaust manifold of the engine. The sub-pressure adjusting unit includes: bypass pipes connected to a plurality of exhaust pipes respectively, which connect each cylinder of the engine with the exhaust manifold thereof; a main discharge pipe configured to discharge exhaust gas introduced into the bypass pipes to the outside when a predetermined overpressure occurs in the exhaust manifold due to a high load on the engine; and an opening and closing valve provided on the main discharge pipe. Therefore, the exhaust manifold may minimize the pulsation of the exhaust manifold under variations of a sudden load caused by the exhaust gas in accordance to the changes in operating conditions of the engine; overload on the turbo charger may be prevented; and the performance of the engine may be stabilized.;COPYRIGHT KIPO 2015
