How to structure long-term contracts

Three-stroke engine: economical,How to structure long-term contracts efficient and environmentally friendly future choice. With the continuous improvement of environmental awareness and the increasing maturity of the automobile market, more and more consumers are beginning to pay attention to the fuel of automobiles. Economic performance. The traditional four-stroke engine has many disadvantages, such as poor power output, loud noise, and excessive exhaust emissions.In the face of these problems, through continuous research and exploration, engineers and scientists have finally launched a new type of engine - a three-stroke engine, which not only solves the disadvantages of traditional engines, but also has better economic and environmental protection performance. I. What is a three-stroke engine? The three-stroke engine (TCE for short) is a new type of engine whose working principle and structure are different from the traditional four-stroke engine. In the traditional four-stroke engine, each piston needs to complete intake, compression, combustion, exhaust and other steps in four strokes, while in a three-stroke engine, each piston only needs to complete intake, compression, combustion and exhaust in three strokes, which simplifies the complex structure of the traditional engine. Advantages of II and three-stroke engines 1. Higher fuel economyCompared with the traditional four-stroke engine, the three-stroke engine actually works with only three strokes per cylinder, so it will consume less fuel under the same power output. In addition, the combustion efficiency of the three-stroke engine is higher, and the fuel can be fully burned, which improves the efficiency of fuel utilization. Two. The power output is more uniform. Because each piston needs four strokes for the traditional four-stroke engine, the output power will inevitably fluctuate intermittently, while the three-stroke engine will not have such a problem. Because each piston only needs to complete three strokes, the rotational inertia during the period of intake, compression, combustion and exhaust becomes smaller, so as to achieve continuous smoothness of the whole process and more stable output power. 3. Be kind to the environment and reduce pollution in the traditional four-stroke engine,Each piston will inevitably produce some harmful substances, such as nitrogen oxides, hydrocarbons, etc., in the process of four-strokes, while the three-stroke engine is more environmentally friendly. Because each piston has one less combustion work during three strokes, in diesel vehicles, the emission of nitrogen oxides can be reduced, while in gasoline vehicles, the emission of hydrocarbons can be reduced. Four. The structure is simple and the maintenance cost is low. Due to the simple structure of the three-stroke engine, it is easier to maintain and maintain. The maintenance work required for the traditional four-stroke engine includes the lubrication of the friction vice, the polishing of the cylinder wall and the adjustment of the valve gap, which disappear in the three-stroke engine, so the maintenance cost will be lower. III. The future of three-stroke engines. At present, with the increasing awareness of environmental protectionWith the continuous improvement of automobile emission standards in various countries, more and more automobile manufacturers and consumers have begun to pay attention to the environmental protection and economic performance of automobiles. With its excellent fuel economy and environmental protection performance, the three-stroke engine has gradually become the representative of the new engine in the future. In the near future, three-stroke engines will become the standard configuration launched by many automobile manufacturers to improve the economy and environmental performance of cars. In a word, the three-stroke engine not only solves the disadvantages of the traditional four-stroke engine, but also has higher economic performance, better environmental protection performance and simpler maintenance cost, which is the development direction of automobile engines in the future. With the continuous improvement and application of its technology, the three-stroke engine will greatly promote the development of the entire automobile industry and create a cleaner, more efficient and low-carbon way of travel for human beings.
