Background
An internal combustion engine is a power machine, and is a heat engine that directly converts heat energy released by burning fuel inside the machine into power. The internal combustion engine in the broad sense includes not only reciprocating piston, rotary piston and free piston engines but also jet engines of the rotary vane type, but the internal combustion engine is generally referred to as a piston engine. Piston internal combustion engines are the most common of the reciprocating piston types. The piston type internal combustion engine mixes fuel and air and burns in a cylinder of the engine, and the released heat energy enables the cylinder to generate high-temperature and high-pressure fuel gas. The gas expands to drive the piston to do work, and then the mechanical work is output through a crank-link mechanism or other mechanisms to drive the driven machinery to work.
The range of internal combustion engines is widely used. Various transport vehicles (such as automobiles, tractors and diesel locomotives) on the ground, machines such as mines, buildings and engineering and the like need to use an air inlet connecting pipe when an internal combustion engine works, and the problem of gas leakage often occurs when the existing air inlet connecting pipe is connected.
