Illustration of the principle of the car engine (Illustrated the operating principle of the car engine,Medical diagnostics HS code classification easy to understand the internal mechanism of the car engine) The car engine is the "heart" of the car, which is an important part of driving the car. For most people, we just need to know how to start, refuel, drive and stop. However, it is very important for us to grasp the performance of the car and maintain the health of the engine to truly understand the internal mechanism of the engine. In this article, we will explain in detail the principle and operation process of automobile engines. What is a car engine? A car engine is an internal combustion engine that pushes the piston to the crankshaft by burning the energy generated by mixed fuel and air to drive the wheels to rotate. It is mainly composed of combustion chamber, cylinder, piston, valve, crankshaft and circuit, etc.The four-stroke of the car engine. Before understanding the specific working principle of the car engine, we need to understand its four-stroke. These four strokes are: 1. Intake stroke: The intake valve opens, and the piston moves down to suck the mixed gas into the cylinder. Two. Compression stroke: the intake valve is closed, and the piston is up to compress the mixed gas. 3. Outbreak stroke: The ignition system is activated, the mixture bursts to generate energy, and the piston is pushed above the lower dead point. Four. Exhaust stroke: The exhaust valve opens and the piston moves up to discharge the exhaust gas from the cylinder. After understanding the four strokes of the car engine, we can begin to understand its working principle. The first step is the intake stroke. As mentioned before, the piston moves down, the valve opens, and the mixed gas is sucked into the cylinder. The second step is to compress the stroke. The intake valve is closed, and the piston begins to move up to compress the mixed gas into the combustion chamber.The third step is the burst stroke. When the piston moves up, the ignition system begins to ignite the mixed gas, producing a flame that continuously releases energy in the combustion chamber. This process will last several strokes until the piston is pushed to the dead point below. The fourth step is the exhaust stroke. After the engine bursts out of the stroke, the exhaust valve opens and the piston moves up to discharge the exhaust gas into the combustion chamber, and then repeat the above four strokes. The workflow of the car engine is controlled by the engine control module (ECM), which collects the driving status of the vehicle through the induction sensor and uses built-in programs to calculate and control the opening of the fuel and air mixing valve, as well as the opening time of the ignition and the opening of the exhaust valve. Through this system, the engine can automatically adjust the proportion of combustion mixtures according to different speeds and load conditions to ensure the best performance and optimal fuel efficiency.Conclusion The principle of automobile engine is complex, but understanding this mechanism is crucial for the maintenance and upkeep of vehicles. For car owners, only by handling the maintenance and upkeep of the vehicle, choosing the appropriate oil and filter, and repairing and maintaining the vehicle on time can provide long-lasting life and best performance for your car. Through the understanding and understanding of the diagram of the automobile engine, I hope to give everyone a more comprehensive perspective to appreciate and understand the great creation of the automobile engine and its internal persuasiveness.
