GAC has independent research and development capabilities and has also built excellent engines.
GAC Trumpchi engine performance: 2.0VTML is Alfa Romeo's technology. Trumpchi changed it to a single spark plug, which improved the quiet performance; it changed the multi-hole nozzle and added DVVT technology. It is basically at the level of mainstream joint venture engines.
GAC Trumpchi GS4 engine technology is relatively advanced. When the engine speed reaches 1450 rpm, the turbine begins to intervene, which enhances the car's acceleration time and fuel economy. This is a reflection of GAC's technology.
GAC Trumpchi’s third-generation 1.5TGDI, 2.0TGDI, and fourth-generation 2.0ATK engines were awarded “Energy Efficiency Star” by the third-party authoritative certification agency China Automotive Research and Development Certification (Tianjin) Co., Ltd. Certificate. GAC’s fourth-generation 2.0ATK engine has achieved a major breakthrough in thermal efficiency of 42.10%.
What is the thermal efficiency of the engine? It refers to the ratio of heat generated by fuel combustion into mechanical energy and is an important indicator of engine economy. The higher the thermal efficiency, the higher the corresponding energy conversion efficiency. When outputting the same power, less fuel will be consumed, and accordingly more fuel will be saved.
With the help of a turbocharger, a higher compression ratio means that the engine is more efficient, can improve more power performance, and is more fuel-efficient. After all, the working characteristics of direct injection engines are Inject fuel directly into the cylinder, using the air flow in the cylinder and the fuel on the piston surface to achieve better atomization.
In the past, self-owned brands still needed to obtain large parts and technology through outsourcing and reverse research and development. Now GAC Trumpchi’s engines can fully rank among the first echelon of self-owned brand engines, and are already as good as mainstream joint ventures. engine. In addition to Changan and Chery, other independent brand engines are also making continuous progress. We are happy to see independent brand car companies investing in and making breakthroughs in key automotive technologies, especially engine technology, and striving for the future of China's automotive industry and environmental protection, as well as the interests of consumers.
