GAS EXHAUST SYSTEM FOR ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a gas exhaust system for an engine capable of increasing engine output by improving air-filling efficiency in an intake stroke as engine output is increased by utilizing exhaust gas of the engine and improving exhaust efficiency in an exhaust stroke of the engine. SOLUTION: A turbine mechanism 2 is provided with a turbine 9 connected to a tip end part or a rear end part of a crank shaft 10 of the engine. As a rotation force 11 from the turbine 9 is applied by blowing exhaust gas from an exhaust manifold 4 to the turbine 9, the engine output is increased. As the turbine 9 integrally rotates with the crank shaft 10, intake action of the exhaust gas is performed in an exhaust stroke. Hence, exhaust efficiency is enhanced and thus engine output is increased. COPYRIGHT: (C)2008,JPO&INPIT
