20 13 On May 30th, Hongqi H7(C 13 1) was officially listed in Beijing. For the first time, Hongqi H7 realized the in-depth independent research and development of the whole vehicle in all fields, platforms and models. The main technical indicators of vehicles are advanced in China, and some of their performances have reached the international level. In terms of power, the 20 15 Hongqi H7 is equipped with two engines, CA6GV and CA4GC20T, independently developed by China FAW Group, with excellent power and economical fuel consumption.
As a high-end V-type six-cylinder engine, CA6GV adopts VIS variable volume cavity and variable length plastic intake system, combined with VVL technology, ensuring advanced fuel economy and ultra-low emission level. The perfect combination of advanced two-stage and three-layer silent chain drive timing system and low noise optimization design makes it more ornamental.
CA4GC20T has achieved technical breakthroughs in general layout, structural strength, vibration and noise, oil supply system and vehicle matching. Leading multi-point injection and supercharged intercooling technology significantly improve horsepower output and fuel utilization, and greatly reduce exhaust emissions.
Extended materials:
The 2.5L and 3.0L engines of Hongqi H7 are completely different from Toyota V6 engine in cylinder bore, stroke and compression ratio. In addition, the included angle between the two cylinders of Hongqi V6 engine is 90, while that of Toyota Crown V6 engine is 60, which shows that the two engines are even different in basic structure. To put it bluntly, they are two completely different engines without any blood relationship. So the myth that "H7 uses the crown engine" can end here.
At the 20 12 Beijing Auto Show, FAW Car has demonstrated its self-developed engine, which is derived from the displacement of a single cylinder of 0.5l. The 4-cylinder engine is 2.0T assembled on today's Hongqi H7, while the V6 engine is 3.0l. The 2.5L engine specially made for government procurement was obtained by changing the cylinder stroke on the basis of 3.0l. In addition, Dr. Li also said that this engine platform can also make V8 and V.
