No matter what kind of engine, it is currently used in different models. Great Wall 2.0T engine is mounted on Haval H6, Haval F7/F7x, Haval H9 and WEY series VV5/VV6/VV7. Changan 2.0T engine is also mounted on CS75 PLUS, CS85 COUPE, CS95 and other models. Moreover, it is worth mentioning that the Great Wall 2.0T engine also has high and low power adjustment. Although the difference is not big, it is indeed two adjusted versions.
2. Factors:
Generally speaking, the fuel consumption depends on the specific model, such as the fuel consumption of Haval F7 2.0T model. The measured data of the Ministry of Industry and Information Technology is 7. 1L/ 100km (two-wheel drive version), and the fuel consumption of Changan CS75 plus 2.0T vehicle is 8. 1L/ 100 km. The fuel consumption measured by the Ministry of Industry and Information Technology of Haval H9 gasoline version is 9.8L/ 100km, and that of changan CS95 Ministry of Industry and Information Technology is 8.9L/ 100km.
It can be seen that even the same class of vehicles, due to different positioning, different body structure (for example, Haval H9 is a hard-core off-road vehicle), different gearbox and other factors, fuel consumption is also very different, which does not include engine technology, user driving habits, vehicle use environment, road conditions and many other factors. So the problem of fuel consumption is really not determined by one or two factors.
3. In terms of motivation
The thermal efficiency of the engine can be used as a reference because the thermal efficiency can represent the fuel economy of the engine to a certain extent. Simply put, it is the use of every drop of fuel. An engine with high thermal efficiency can squeeze out more energy and save more fuel. But what we know so far is that.
The 2.0T engine of Great Wall with code name GW4C20B, that is, several engines of Haval brand mentioned above, has a thermal efficiency of 38%, while the 2.0T engine of several models of WEY brand has code name E20CB, and the thermal efficiency is unknown at present. In addition, the specific thermal efficiency of Changan Blue Whale 2.0T engine is unknown at present, but it is certain that there is little difference in fuel consumption and performance between Great Wall 2.0T engine and Changan 2.0T engine.
