1On October 30th, the 20 1 1.5 GDIT engine independently developed by Great Wall Motor won the title of "Top Ten Engines" in the annual "China Heart" selection activity, and the product applied for 9 1 patents on the whole machine; The cylinder head integrated exhaust manifold technology has won four patents, and the CVVL continuously variable valve lift technology independently developed is adopted for the first time, which integrates advanced technologies such as central injector, cylinder head integrated exhaust manifold, high transient response electronically controlled supercharger, two-stage variable displacement oil pump, dual VVT for intake and exhaust, and dual-loop cooling system, and the technology has reached the international advanced level.
The maximum power of this 1.5GDIT engine is 124KW. At 1000rpm, the turbine started to intervene. At 1400rpm, the maximum torque can reach 285Nm, and the torque can reach190 nm/L. In terms of fuel consumption control, advanced technologies such as fully variable valve lift (CVVL), integrated exhaust manifold of cylinder head, two-stage variable displacement oil pump and dual VVT of intake and exhaust are adopted to effectively ensure better fuel economy. The comprehensive fuel consumption of the Ministry of Industry and Information Technology is 6.8L/ 100KM.
Why is this 1.5GDIT engine so superior in performance and so low in fuel consumption? This begins with CVVL being a continuously variable valve lift technology. Please find the network yourself. It can only be said that the main function of CVVL technology is to reduce fuel consumption. Engine models with CVVL technology can achieve a maximum fuel consumption reduction of 8.4%.
With the 1.5GDIT engine and 7DCT dual clutch wet power shift independently developed by Great Wall, the power output is extraordinary, and the large torque has greatly improved the handling comfort.
