As the world's third largest energy source after coal and oil, natural gas plays an increasingly important role. Its main component is methane, which is a gaseous fuel that can be fully mixed with air. After being burned by a gas engine, there are basically no particulate emissions.

[0003] For example, the temperature measuring device, engine and vehicle with the publication number of CN215595730U mainly work when the piston of the engine is working. The volume of the thermal expansion part expands, so that the negative contactor squeezes the reset spring and then contacts the negative electrode of the battery. After the piston of the engine stops working, the volume of the thermal expansion part shrinks. Under the action of the reset spring, the negative contactor disconnects the negative contactor from the negative electrode of the battery, avoiding the battery of the temperature measuring device being always powered on when the piston is in the non-working state, thereby increasing the temperature measuring time of the piston of the engine.
