Fuel mixing ratio: the mixing ratio of fuel and air, commonly known as the air-fuel ratio, directly affects the performance and fuel efficiency of the engine. 19. Piston stroke: the distance between the piston moving up and down affects the output power of the engine. 20. Air exchange time: the duration of opening and closing of the intake valve and exhaust valve, which affects the efficiency and performance of the engine. IV. Working principle of the engine 21.Air intake duct: the pipe through which air enters the engine from the outside. 22. Air filter: filter impurities in the air through the filter to improve the fuel utilization rate. 23.

Trottle: Control the air flow into the engine, affecting the output power and fuel economy of the engine. 25. Inlet manifold: send air from the air filter to each cylinder. 26. Gas distribution system: It is used to control the opening and closing time of the valve and adjust the process of fuel combustion in the combustion chamber. 27. Fuel injector: inject fuel into each cylinder in proportion. 28. Spark plug: generates spark ignition, causing the fuel and air mixture to ignite and burn. 29. Exhaust system: Discharge the combustion gas out of the engine to reduce pollutant emissions.Thirty. Cylinder wall: the support point of the parts in the cylinder, which also plays a sealing role. V. Engine performance index 31. Power: The output power of the engine is usually measured by horsepower (HP) or kilowatt (KW). Thirty-two. Torque: The size of the torque output through the engine affects the acceleration and driving performance of the vehicle. Thirty-three. Fuel consumption: The amount of fuel consumed per kilometer of the engine is usually calculated in liters/100km (L/100KM). Thirty-four. Emissions: The emission content of pollutants produced by engines is usually measured by European standards commonly used worldwide. 35. Noise: the amount of noise generated when the engine is running. VI. Engine maintenance 36. Replace the oil and oil filter regularly to maintain the lubrication effect. Thirty-seven. Replace the air filter regularly to prevent impurities from entering the engine.38. Replace spark plugs regularly to ensure combustion efficiency. 39. Regularly check the cylinder head and cylinder structure to determine whether there are cracks and deformations. 40. Regularly check the cylinder compression and engine compartment emissions to determine whether the engine is normal. VII. Car maintenance and engine maintenance 41. Car maintenance: refers to the daily inspection, cleaning, maintenance and repair of the whole vehicle. 42. Engine maintenance: refers to the maintenance and upkeep of the engine to ensure its performance and service life. 43. Engine failure: refers to the problems of functional abnormalities, damaged parts or abnormal noise signals that occur during the use of the engine. Forty four. Preventive maintenance: Before the failure occurs, the car should be regularly tested and repaired according to the manufacturer's recommendations and conditions of use. Forty-five. Maintenance interval: refers to the maintenance and replacement of parts of the car according to different types of maintenance cycles.VIII. Engine repair 46. Engine disassembly: refers to the disassembly and installation of the lifting table, workbench and frame of the engine. 47. Fuselage repair: engine body maintenance, including the plane of the body and the number of restorations. 48. Piston control: repair the small vibration or poor sealing of the piston, and repair the camshaft, rocker arm and other parts. Forty nine. Fuel system: repair the fuel injection system and other components. 50. Exhaust system: repair the exhaust pipe and other components. IX. Engine environmental protection 51. Engine emission standard: refers to the content of harmful substances in the exhaust gas released by the engine during fuel consumption. Fifty-two. Pollution prevention and control: refers to the control and treatment of specific pollutants to reduce the output of pollutants in the environment. 53. Emission control: Through emission control technology, the pollutants in the exhaust gas are reduced below the national standard.54. Green technology: represents the development direction of future automobile research and development, and focuses on promoting energy-saving and environmental protection technologies of automobiles. 55. Application of new materials: improve the effect and durability of the engine through new technology and raw materials. X. Cost-effective choice 56.
