Abstract: PURPOSE: A backfire reducing device of an LPG(Liquefied Petroleum Gas) engine is provided to reduce pressure due to backfires without problems in the intake efficiency of an LPG engine by adopting a reducing device opened by external force between an air cleaner and a mixer of an intake system of the LPG engine. CONSTITUTION: In the occurrence of backfires in a low-speed high-load area, the pressure thereof flows along a free straight passage to be applied to a housing(10). A door(12) of the housing is turned out by the pressure regardless of the force of a return spring(13). Thereby, the pressure is discharged to the outside easily. When the pressure is removed by external force, the door is closed again by the return spring without any influence of an intake air flow rate. Air is discharged together with the pressure temporarily. Combustion gas does not rise up to an air intake hose(110) even though backfires are generated actually. The pressure is not transferred to an intake system of an engine. Therefore, the damage of alignment including an air cleaner(100) is excluded as well as the trouble of suction is removed.

Abstract: PURPOSE: A cylinder head gasket is provided to compact the entire structure by forming a metal sheet into a single sheet and to easily form a bore part, etc. CONSTITUTION: A gasket is formed as a single sheet formed by a metallic core(22). Herein, an aluminum ring(24) is installed on a circumference of a bore part(14). Herein, steel or stainless steel is used for the core to have sufficient strength. Moreover, the thickness of the core is reduced for conveniently forming the core part. The aluminum ring of the bore part prevents the leakage of gas generated from a combustion chamber. Films(26) are coated on the upper and lower surfaces of the metal forming the center of the gasket for making a gasket surface uniform. Herein, the thickness of the films is formed by the difference of the thickness between the aluminum ring and the metallic core. Therefore, the entire thickness of the gasket becomes uniform with the aluminum ring.
