Automobile engine detection (automobile engine detection technology: more accurate and DigiPlusefficient) With the continuous development of the automobile industry, automobiles play an increasingly important role in our daily life. The engine of a car is the heart of a car, and it plays a crucial role in the performance and service life of the vehicle. During the operation of the vehicle, the engine will have problems for various reasons, such as poor exhaust system, oil deterioration or idling jitter. In order to better protect the vehicle engine, we need to use automobile engine detection technology to better understand the status of the vehicle engine, carry out timely repair and maintenance, and extend the service life of the vehicle. I. Automobile engine inspection process Automobile engine inspection is generally divided into the following links: 1.Check the exhaust system: The engine exhaust system is an important part of vehicle operation. The exhaust pipe and silencer need to be checked and cleaned regularly to ensure that the engine discharge is smooth and does not affect the performance of the engine. Two. Check the engine oil: Engine oil is an important lubricant for the normal operation of the engine. If the oil deteriorates or the amount of oil is insufficient, it will shorten the life of the engine and even fail. Therefore, it is very important to change the oil regularly and check the oil pressure. 3. Check the cooling system: A large amount of heat is generated when the car engine is running, and the cooling system needs to dissipate it. If the cooling system fails, the engine temperature will rise, resulting in vehicle failure. Therefore, it is very necessary to check the cooling system regularly and add coolant. Four. Detect the working status of the engine: Testing the engine can fully understand the operating status of the engine.Determine whether the engine is normal by testing the curve diagram, measuring the engine output power, torque and other parameters. 5. Maintenance and repair: Carry out regular engine maintenance and repair according to the test results to extend the service life of the engine. II. Automobile engine detection technology 1. OBD system technology: OBD, also as On-Board Diagnostic, is an advanced technology for engine detection of modern automobiles. It can find engine faults through the fault code diagnosis system and provide corrective solutions. The OBD system can also record vehicle performance and provide accurate car status reports. Two. Environmental protection detection technology: Environmental protection detection technology judges the working status of the engine through automobile emission detection. By analyzing the emission content, measuring the engine exhaust volume and other parameters, the engine state can be judged more accurately.3. Sound analysis technology: Sound analysis technology can judge the working state of the engine by analyzing the sound of the engine. This method can diagnose engine faults quickly and accurately. Four. Dynamic test technology: Dynamic test technology comprehensively measures the performance of the vehicle by measuring the acceleration, braking distance, driving speed and other parameters of the vehicle during operation, and provides accurate test reports. 5. Sensor technology: Sensor technology can provide accurate engine abnormal information by measuring the operating speed, vehicle speed, exhaust volume and other parameters of the engine. III. Conclusion The car engine is the most critical part of the car operation, and the maintenance and repair of the engine are very important. By using modern automobile engine detection technology, the performance and service life of the vehicle can be greatly improved and the failure rate of the vehicle can be reduced. Car lineThe industry is developing in the direction of safety, environmental protection and intelligence, and the application of automobile engine detection technology will become more and more extensive and play an increasingly important role.
