When it comes to fuel consumption, many people know that it is related to the weight of the vehicle. In fact, the impact of vehicle weight on fuel consumption is not as large as many people think. The experimental results show that for each increase of about 200kg vehicle weight, the combined fuel consumption per 100km only increases by about 0.4L, which is calculated as an integrated road condition. Assuming that the oil price is calculated as 6RMB/L, it will increase 2.4 cents per kilometer. Some people may say that tire pressure, wind resistance, and so on, these are all great impact on fuel consumption, but the most basic factor, I am afraid there are not many people who know! In fact, the root cause of fuel consumption is the matching of power systems. This can be said to be a basic condition for determining fuel consumption. What is a match? The most popular argument is to design the gear ratio and gear ratio of the gearbox and the final transmission ratio of the final gear according to the output characteristics of the engine. If it is an automatic transmission, it also includes the control logic of the transmission, which is when the gearbox shifts. After the development of the engine is confirmed, it is through the matching of the transmission to achieve a balance between power and economy. If the number of shift gear ratios, gear ratios, and shift control logic of the automatic gear are compatible with the characteristics of the engine output, then the vehicle can remain in a range of speeds with sufficiently high fuel efficiency as long as the vehicle is driving. , greatly reducing the overall fuel consumption. This fundamental thing is ignored by many people. Moreover, it is difficult to improve by the owner himself. Why? Very simple, tire pressure is not enough qi is enough, the tire power to replace it much better, the weight of the car will have less impact on the usual car in the car just fine, but the transmission you an ordinary car owner can say to change it? ? So this is very much considered the tuning of the car factory, which is also one of the core technologies of car manufacturers.
High precision double side surface grinding or fine grinding is a super finishing process performed by removing material from two surfaces of a component resulting in extremely precise geometric accuracy and surface finish. Typically, it is the last grinding step of a mechanical production chain utilized to improve and/or correct the geometry of parts coming from sintering, sawing, molding or similar operations. Depending on the application, the stock removal also can be taken from just one surface.
