What is the Principle of Automobile Movement?

[McRonan]

The principle of automobile movement is that the engine converts the energy of gasoline into kinetic energy to drive the car, obtaining kinetic energy by burning gasoline inside the car engine. The following is a detailed introduction to the four-stroke engine: 1. Classification: The four-stroke engine belongs to the reciprocating piston-type internal combustion engine. According to the type of fuel used, it is divided into three categories: gasoline engines, diesel engines, and gas fuel engines. Piston-type internal combustion engines that use gasoline or diesel as fuel are called gasoline engines or diesel engines, respectively. Piston-type internal combustion engines that use natural gas, liquefied petroleum gas, and other gas fuels are called gas fuel engines. Gasoline and diesel are petroleum products and are traditional fuels for car engines. Non-petroleum fuels are called alternative fuels. Engines that burn alternative fuels are called alternative fuel engines, such as ethanol engines, hydrogen engines, methanol engines, etc. 2. Working Process: A four-stroke gasoline engine completes a working cycle through four strokes: intake, compression, power, and exhaust. During this process, the piston moves up and down four times, and the corresponding crankshaft rotates twice.
