What does the so-called vehicle weighting mean? The so-called "lightweight" vehicle is a lightweight vehicle that satisfies vehicle structural strength, stiffness, vibration noise, passive safety, and durability. Reducing its own weight is an important means for vehicles to achieve safety, environmental protection and energy saving goals. As the engine's most important powertrain, reducing its weight undoubtedly has extraordinary significance. What can lightweighting bring in practical applications? According to the World Aluminum Association report, every 10% reduction in the vehicle's self-weight, fuel consumption can be reduced by 6% to 8%. Analysis of data from Dongfeng Cummins, a well-known brand of the entire automobile industry, shows that for every 2 tons of reduction in gross cargo weight, fuel consumption per 100 kilometers can be reduced by 0.8L, which means that for every 1 ton reduction, fuel consumption can be reduced by 1.4%. It can be seen that "lightweight" can effectively improve fuel economy and reduce harmful gas emissions. On the other hand, we all know that the vehicle's driving resistance is proportional to the weight of the vehicle, and the increasing weight of the vehicle will cause most of the energy consumption to be consumed in its own weight, rather than meeting the needs of passenger and cargo transportation. The lightweight design of vehicles, including engines, can effectively increase production efficiency. "Lightweight" is not incompatible with vehicle safety In fact, the lightweight of the engine does not mean to reduce its safety performance and performance. As long as the design, material selection, and manufacturing process are reasonable, light weight can fully meet the state's requirements for automotive safety, ride comfort, vibration and noise standards, and durability, ensuring performance. At the same time, the lightweight design of the vehicle, including the engine, has improved the safety of our vehicles. It is well-known that the energy consumed by a truck when braking is also proportional to the mass. In the simplest example, the same speed, the light truck has a short braking distance with a certain specific gravity. In other words, the lighter the truck, the brakes are required to brake at the same initial speed. The smaller the energy consumed, the faster the braking deceleration, and the shorter the braking distance, the better the braking performance will be. The active safety of the vehicle will become better. Therefore, a reasonable truck weight reduction will not only reduce the safety performance of the vehicle, but also contribute to the improvement of the safety performance of the vehicle. What are the ways to achieve lightweighting of the engine? Nowadays, there are mainly the following ways to achieve lightweighting of the engine: 1. Choose lightweight high-strength composite materials such as aluminum alloy/magnesium alloy to replace traditional materials such as gray cast iron; 2. Functional components, such as the structure and composition of external accessories, optimization and light weight; 3. The integration or modularization of similar components and components with similar functions; 4. Structural optimization of those critical parts in the engine, such as the crankshaft. The Dongfeng Cummins Engine is a model of lightweighting in the industry. These requirements have already been reflected in advanced designs: 1, the overall use of modular design, the total number of parts is about 20% less than other engines; 2. High-pressure cast aluminum technology is used for flywheel housings and gear chambers, and some parts are made of high-strength composite materials, which is approximately 20% lighter than similar products. 3, as an important part of the power output, the crankshaft is made of alloy steel forging, effectively increasing the fatigue strength of the crankshaft. With the gradual improvement of China's road regulations, lightweight design will exist for a long time. For lightweight, autonomous design, as an engine manufacturer, we still have many areas for improvement. In short, the energy saving and emission reduction that is so large that the national resources are so large that the daily income of each of our Kang powders is inseparable. We should correctly treat the existence and trends of lightweighting of vehicles, including engines, and be reasonable. application.

“Lightweight†has been paid more attention by more and more owners. 9.21 Five ministries and commissions have jointly supervised the operation to make “lightweight†a big fire. The purpose of switching to lighter models is to maximize cargo loading and increase transportation efficiency without increasing the total cargo weight.
