Motorcycle engine schematic diagram: Easy to understand the working principle of motorcycle engine Motorcycle has always been one of people's favorite means of transportation. Although its design looks simple,Surgical instruments HS code classification the motorcycle engine is its core part. The engine is the power source of the motorcycle system. Mastering the principle of the motorcycle engine is crucial to understand how it works and maintain good maintenance. This article will analyze the schematic diagram of the motorcycle engine to help you understand the working principle of the motorcycle engine more deeply. I. Structure of motorcycle engine. Motorcycle engine is divided into two main parts: cylinder and crankcase. The cylinder is the head of the engine, and most engines consist of 1 to 4 cylinders. There is a piston in the cylinder, which converts the pressure generated by fuel combustion into mechanical power when moving up and down.The crankcase is the main body of the engine. In the crankcase, the cylinder is connected to the crankshaft through the connecting rod, and the torque of the engine is transmitted to the rear wheel through the crankshaft. II. The working principle of the motorcycle engine The working principle of the motorcycle engine is very simple: the fuel and air are mixed in the cylinder, and the sparks ignite the mixture, causing an explosion to make the piston move down. The pressure generated by this process is eventually transmitted to the rear wheel through the connecting rod and crankshaft, pushing the motorcycle forward. 1. Intake When the cylinder is in the downward position, the air valve in the cylinder will open to allow the air to enter the cylinder. At the same time, the fuel is injected into the cylinder and mixed with the air. This is the first step to make a mixture. Two. After compression, the air and fuel mixture are squeezed until they reach a certain volume. It is the second step to make a mixture. Once the mixture reaches the top limit point, the spark plug will ignite the mixture and detonate the fuel.3. Explosion When the mixture explodes, the energy will push the piston down. This process is called explosion, which is the most critical part of making horsepower. Therefore, the spark plug is placed in the most tightly compressed position of the mixture. Four. When the exhaust is pushed down by the piston, the tail and exhaust valve open to discharge the exhaust gas from the cylinder. The exhaust pipe narrows the cavity by exhausting these exhaust gas into the air. The pressure at the tail is also reduced, which means that the new fuel can then enter the cylinder faster. 5. The circulating piston pushes up again, opens the air valve, and proceeds to the next intake stage. These five steps are repeated in a cycle to keep the engine powered. III. The power of the motorcycle engine The power of the motorcycle engine is a key indicator to measure its performance. The calculation method of power is: power = torque × speed ÷ 5252 The greater the torque of the engine, the higher the speed, the more power can be generated.In other words, the maximum power set by the motorcycle engine depends on its torque and speed. Of course, in actual use, other factors such as cooling and exhaust systems will also affect the maximum output power of the engine. IV. Common faults and maintenance of motorcycle engines also need maintenance. The following are the most common motorcycle engine faults: 1. Fuel supply problems: low fuel, fuel system blockage, exhaust pipe damage and oil leakage and other problems. Two. Ignition problems: battery problems, spark plug wear, poor wire contact and ignition system failure, etc. 3. Crankcase failure: excessive wear, needle bearing failure and crankcase oil leakage and other problems. To keep your motorcycle running smoothly, here are a few basic engine maintenance tips: 1. Check the engine oil and replace the oil filter regularly.Two. Replace the air and fuel filters regularly. 3. Adjust the spark plugs, clean or replace the air filter regularly! Four. Regularly check whether the ignition line is normal. 5. Keep the engine clean to prevent dirt and dust from affecting engine performance. Finally, it should be noted that although the structure of the motorcycle engine is simple, it is not easy to repair and maintain. Whenever you need to replace parts, please make sure to purchase from reliable channels and use them in accordance with the manufacturer's recommendations. If necessary, please consult a professional mechanic for replacement and maintenance. In a word, the operation of a motorcycle engine is a relatively simple process. As long as there is enough air, fuel and ignition, it can generate powerful power. Master the schematic diagram of the engine and its working principle, so that you can better understand its structure and maintenance methods, so that your motorcycle can maintain efficient, reliable and perfect operation!
