What is the most feared substance entering an engine?
1 Answers
The most feared are granular impurities, as they can render the engine ineffective. Specific details are as follows: 1. Automotive engine: It is the device that provides power for a car, serving as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental friendliness. Depending on the power source, automotive engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. 2. Working principle: A four-stroke gasoline engine mixes air and gasoline in a certain proportion to form a good combustible 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 it to perform reciprocating linear motion, thereby outputting mechanical energy externally through the connecting rod and crankshaft flywheel mechanism. A four-stroke gasoline engine completes one working cycle during the intake stroke, compression stroke, power stroke, and exhaust stroke.
