What brand of engine does the Hongqi H9 use?
2 Answers
Hongqi H9's engine is produced by China FAW. This V6 engine, codenamed CA4GC20TD-31, is a domestically independently developed V6 engine. The CA4GC20TD-31 V6 engine is not equipped with a common turbocharger, but rather with a supercharger. This engine incorporates many technologies, such as a 200BAR fuel injection system. High-pressure fuel injection can effectively improve fuel atomization, thereby promoting gasoline combustion, which not only enhances power but also effectively reduces harmful emissions. During low-speed driving, the variable tumble technology can reduce the intake cross-section to lower emissions; during high-speed driving, it increases the intake cross-section to boost air intake. The engine consistently maintains excellent dynamic responsiveness. Coupled with the supercharger, it provides the engine with more efficient air intake, enhancing power while also improving fuel combustion quality.
I recently studied the specifications of the Hongqi H9, which is mainly equipped with an engine independently developed by FAW. The primary models are a 2.0T inline-four turbocharged engine and a 3.0T V6 supercharged engine, both entirely produced at FAW's powertrain factory in Changchun. After test-driving the actual vehicle, I found that the 3.0T version starts up exceptionally quietly, accelerates very smoothly, and has ample power reserves. Previously, many people wondered whether Audi or Toyota engines would be used, but as a premium domestic brand, Hongqi has indeed achieved self-reliance in core technologies. The red valve covers in the engine bay are custom parts, and even the crankshaft machining precision reaches micrometer levels. These details reflect the progress of Chinese manufacturing and are something to be proud of.
