In the past ten years, the Great Wall GW4G 13 gasoline engine went on the market, becoming the first truly self-developed gasoline power in the Great Wall. Adopting all-aluminum cylinder block, in-line four-cylinder, multi-point injection and VVT variable valve timing technology, the engine has a maximum power of 92 HP and a maximum torque of118n m. This engine was also used in the first dazzling car model of the Great Wall, and was selected as one of the first ten China cars in the same year.
Almost at the same time as the GW4G 13 gasoline engine, there is also a 1.5L engine, code-named GW4G 15. It is also from these two gasoline engines that Great Wall embarked on the right track of independent research and development and production of engines.
Moreover, this engine code GW4G 15 is also widely used in Great Wall models, such as Great Wall Cool Bear, C30, Haval M4, Haval H 1, Haval h2 and so on. Among them, the annual sales volume of Great Wall C30 exceeded 654.38+0.5 million at the peak, ranking first independently. Unfortunately, due to the brand transformation, this former national car gradually withdrew from the historical stage, but the road of independent research and development of engines by Great Wall has just begun. The introduction of 4G 13 and 4G 15 solved the heart problem of small cars in the Great Wall, but Haval H6, which had already undertaken a single sales volume at that time, did not have a suitable gasoline engine, which made the Great Wall in trouble again.
So can a turbocharged engine be introduced to solve the power problem for Haval H6?
For this reason, the Great Wall introduced the 4G 15T engine, which was turbocharged by adding a turbine to 4G 15, with the maximum power 133 horsepower and the maximum torque188 N m, but it was not installed on Haval H6, and was mainly installed on C30 vehicles. At that time, the bright red words 1.5T on the new C30 trailer indicated the engine. Subsequently, the more advanced 4G 15B has been born, with a more advanced supercharger engine. The maximum power reaches 150 horsepower, and the maximum torque reaches 2 10 Nm. It is officially equipped with Haval H6. Compared with the previous 4G69 engine, the fuel consumption has been greatly reduced, the power has been significantly improved, and the market competitiveness has been qualitatively improved, which has helped Haval H6 to hold the position of SUV champion and laid a solid foundation for Great Wall to focus on SUV models.
Soon, it's time for China automobile brands to develop rapidly for several years. Great Wall Motor took the first place in the sales volume of China automobile brand SUV, and announced that it would focus on SUV models at Harvard Million Festival.
Engine updates are inevitable.
20 17 is an extremely important year for the Great Wall. In addition to announcing the focus on SUV models, it also brought a new generation of 1.5T engines.
This engine code 4B 15(4B 15A) is a brand-new engine independently designed, developed and manufactured by Great Wall. The process of growth is always long, from imitation to improvement to complete independence of 4B 15(4B 15A). Since then, the Great Wall has had the ability to independently develop advanced engines.
