Description

technical field [0001] The invention relates to a rubber part for an automobile, in particular to a method for preparing a rubber pipe for an automobile internal combustion engine fuel system. Background technique [0002] An internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by burning fuel inside the machine into power. Internal combustion engines in a broad sense include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller jet engines, but the internal combustion engines generally refer to piston internal combustion engines. Piston type internal combustion engine is the most common with reciprocating piston type. The piston-type internal combustion engine mixes fuel and air and burns it in its cylinder, and the heat energy released makes the cylinder generate high-temperature and high-pressure gas. The expansion of th...
