In industrial production, automobile manufacturing is undoubtedly a complex project, involving the design, processing and assembly of many precision parts. This paper will discuss some key technologies and practical experience in the process of design and manufacture, taking the automobile heart-engine as an example.
First, the engine overview
The engine is the power source of the car, which is responsible for converting the heat energy generated by fuel combustion into mechanical energy and driving the car forward. According to the different working principles, it is mainly divided into two categories: gasoline engine and diesel engine. In recent years, with the enhancement of environmental awareness and technological progress, new energy power systems (such as motors) have also developed rapidly.
Second, the key technology and practice
1. The application of lightweight materials
Reducing weight under the premise of ensuring strength is very important for improving fuel economy and reducing emissions. At present, aluminum alloy has become one of the first choice materials for cylinder block, piston and other important parts. In addition, carbon fiber composites are widely used in high-performance sports cars and racing cars because of their excellent specific strength.
2. Efficient combustion technology
Direct injection technology can achieve more accurate fuel control and promote complete combustion, thus improving efficiency and reducing pollutant emissions. Turbocharging technology can increase the intake air volume by using the exhaust pressure, so that it can output more power under the same displacement while maintaining good economy.
3. Intelligent management system
ECM(Engine Control Module), as the core part of the automotive electronic control system, automatically adjusts the ignition advance angle, fuel injection timing and other factors by analyzing and processing various sensor data to ensure the best performance. Modern intelligent ECM also has fault diagnosis function, which is convenient for maintenance.
4. Energy conservation and environmental protection measures
With the continuous improvement of global environmental protection requirements, technologies such as low-friction design, variable valve timing and exhaust gas recirculation have been widely adopted, effectively reducing fuel consumption and harmful substance emission levels.
Third, the conclusion
To sum up, the design and manufacture of automobile engines is a multidisciplinary process, which requires not only advanced theoretical support, but also rich practical experience accumulation. In the future, with the continuous emergence of new materials and technologies, it is believed that the auto parts industry will usher in a broader development space. At the same time, in the face of increasingly severe environmental problems, how to balance the relationship between technological innovation and sustainable development will be a common challenge for all practitioners.
