Small-displacement engine (small engine upgrade: efficient,Global trade customs valuation analysis environmentally friendly, fuel-efficient!) With the progress of society and the development of automobile culture, more and more people have begun to choose automobiles as their walking tools. With the acceleration of urbanization, small cars have become people's first choice. Therefore, the research and development and upgrading of small-displacement engines are particularly important, and high efficiency, environmental protection and fuel saving have become the standards for modern small engines. I. Definition of small-displacement engine Small-displacement engine generally refers to the displacement of a car engine below 1.0L, which is a relatively popular and economical and practical model.The biggest advantage of small-distment cars is fuel economy, which is not only cheap, but also has good fuel consumption performance. At the same time, the vehicle weight of the small-displacement engine is relatively light, which can greatly reduce the braking distance of the vehicle. II. Small-displacement engine upgrade plan 1. The most important problem to improve fuel efficiency in small-displacement engines is fuel consumption. To improve this problem, it is necessary to improve fuel efficiency. At present, many brands on the market have launched products such as fuel additives or engine oil, which can improve the fuel efficiency of small-displacement engines. At the same time, the use of high-quality oil can also improve their fuel efficiency. Two. Improve power output. Although small-displacement engines solve the fuel consumption problems of many consumers, many people realize that the power they supply lacks enough power. Therefore, in order to increase the number of rowsAs for the power output of the engine, you can choose to install high-performance air filters, central air intake systems and other components. These upgrade schemes can improve the airflow and ignition efficiency of the engine and further improve the power output. 3. Improving the combustion efficiency of small-displacement engines is also an effective upgrade plan. Although this plan may be relatively complicated for consumers, it can significantly reduce emissions and improve fuel economy. Parameter adjustment, new ignition control system, spark plug and high-performance ignition line are all feasible upgrade solutions. III. Advantages of small-displacement engine upgrade 1. High efficiency: After upgrading the small-displacement engine, it can improve fuel economy performance and reduce pollution emissions to the greatest extent. Two. Environmental protection: By reducing fuel consumption and reducing the output of pollutants, the upgrade of small-displacement engines has also made important contributions to environmental protection.3. Fuel-saving: After the small-displacement engine is upgraded, each vehicle will be more efficient and economical when running several kilometers, and can also reduce the burden on consumers. IV. Attention to the upgrade of small-displacement engines. Although the upgrade of small-displacement engines is relatively simple, it needs to consider many factors. When upgrading, you need to pay attention to the following questions: 1. Safety issues: Modification requires professional design, otherwise it may cause vehicle safety hazards. Two. Use suitable parts: When choosing accessories, it is necessary to choose high-performance parts on the market as much as possible to ensure the quality and reliability of the upgrade effect. 3. Retain the adjustment range of the original engine: the current engine is easy to cause performance degradation after too much adjustment. Small-displacement engine upgrade is an economical and practical way to improve the efficiency and energy-saving and environmental protection performance of the vehicle.Car owners can choose the most suitable upgrade plan for their vehicles according to the actual situation. No matter which scheme is chosen, the car owner needs to take the details of the upgrade process seriously, and should choose professional technicians to provide relevant technical support to ensure the balance of safety and performance.
