The Marble and granite HS code referencesmodernization of the bus power system With the continuous expansion of the scale of the city, the number and role of buses are also becoming more and more important as an important part of urban public transportation. For modern cities, improving the operation quality, efficiency and environmental protection performance of buses has become one of the important tasks of urban public transportation construction. As the core component of the bus power system, the quality and efficiency of the bus engine play a crucial role in the performance of the whole system.In the modern urban bus system, improving the efficiency and environmental protection performance of the bus engine has become a necessary link in the modernization and transformation of the bus power system. I. Problems with the bus engine The traditional bus engine has the following problems: 1. High pollution: Traditional bus engines will produce a large amount of exhaust gas in the process of use, causing serious pollution to the urban air environment and bringing great harm to people's health. Two. High energy consumption: The traditional bus engine has high fuel consumption and low efficiency, which has a negative impact on the operating cost and environmental protection performance of the bus. 3. Loud noise: The traditional bus engine is noisy when running, which affects the quality of life and sleep of urban residents. II. Modernization of bus power system In order to solve many problems existing in traditional bus engines, the bus power system has ushered in modernization.1. Pollution reduction: The modern bus power system adopts a new type of environmentally friendly diesel, CNG or LNG engine with high power and low emissions. Its engine emission level can be reduced to European level 4, level 5 and other standards, thus reducing the pollution of buses to the urban air environment. Two. Energy consumption reduction: The modern bus power system adopts an advanced power device and intelligent control system, which can automatically adjust the operation mode of the engine according to the road conditions and load, thus reducing the energy consumption of the bus, saving fuel consumption costs, and improving the efficiency of the bus. 3. Noise reduction: The modern bus power system adopts a light, silent and fuel-efficient engine, and adopts sound absorption, sound insulation and other measures, which effectively reduces the noise during bus operation and ensures the quiet rest of urban residents. Except for thisIn addition, the modern bus power system also pays attention to the maintenance and safety of the engine, which provides a more reliable guarantee for the operation of the bus. III. The effect of the modernization of the bus power system The effect of the modernization of the bus power system is not only the performance improvement of the bus, but also the positive effect on the environment, society and users. 1. Effect on the environment: The modern bus power system significantly reduces the exhaust emissions of buses, significantly improves and purifies the urban air environment, and improves the quality of life and health of urban residents. Two. The role of society: The modern bus power system improves the operation efficiency and maintenance costs of buses, provides reliable technical support for the construction of urban public transportation systems, and provides more options for urban traffic congestion relief and green travel.3. The role of users: The modern bus power system improves the comfort and safety of the bus, improves the service quality and image of the bus, and improves the public's travel experience and satisfaction. IV. Conclusion As the core component of the bus power system, the quality and efficiency of the bus engine play a crucial role in the performance of the whole system. The modernization of the bus power system is not only a replacement for traditional bus engines, but also a challenge to the improvement of urban traffic conditions, environmental protection and sustainable development. Technical research and industrial guidance should be increased to provide stronger support for the sustainable development of cities.
