What is the principle of an engine?
1 Answers
The principle of an engine is: A four-stroke gasoline engine mixes air and gasoline in a certain proportion to form a good mixture, which is drawn into the cylinder during the intake stroke. The mixture is compressed, ignited, and burned to generate thermal energy. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to perform reciprocating linear motion, and mechanical energy is output externally through the connecting rod, crankshaft, and flywheel mechanism. Relevant information is as follows: 1. Composition: The engine consists of two major mechanisms, the crank connecting rod mechanism and the valve mechanism, as well as five major systems including cooling, lubrication, ignition, fuel supply, and starting systems. The main components include the cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc. 2. Cylinder: The working chamber of a reciprocating piston internal combustion engine is called the cylinder, and the inner surface of the cylinder is cylindrical. The piston that reciprocates in the cylinder is hinged to one end of the connecting rod through the piston pin, and the other end of the connecting rod is connected to the crankshaft. The crankshaft is supported by bearings on the cylinder block and can rotate within the bearings, forming the crank connecting rod mechanism. When the piston reciprocates in the cylinder, the connecting rod drives the crankshaft to rotate.
