CA4GC20TD-31 is the engine model used by Hongqi, with a maximum horsepower of 252 HP, a maximum power of 185 KW, a maximum power speed of 5500 rpm, and a peak torque of 380 N.m. Hongqi's engines are developed by FAW. Therefore, the engines of Hongqi cars are all domestically produced. For the daily of Hongqi's engines, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, which can cause various problems for the engine. To avoid faults, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When the oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing the oil to bypass through the bypass valve and bringing dirt back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and the cylinder wall, mixing with metal powder from part wear to form sludge. A small amount of sludge remains suspended in the oil, while a large amount precipitates, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and the engine.

Most of the engines in Hongqi cars are indeed domestically produced. I've always been fascinated by automobiles, especially the development of domestic brands. As a veteran Chinese automaker, FAW Hongqi has been independently developing engines since the CA72 in 1958, such as the classic V8 engine. Current models like the Hongqi H9 are equipped with domestically produced 2.0T or 3.0T turbocharged engines, with core components all made in China. While they may draw on international technology, overall they achieve domestic production. This reflects the progress of China's automotive industry—reliable in quality, low in costs, and delivering robust driving performance. In the future, Hongqi is also advancing electrification, using domestic power systems to reduce emissions. As an enthusiast, I take pride in seeing domestic brands rival international standards and drive the trend toward green mobility.

Having driven a Hongqi car for several years, I believe the engine is largely domestically produced. My Hongqi H5 runs smoothly, and after researching, I found that FAW Group manufactures engine components in its own factories, reducing reliance on imports, with good reliability. It's fuel-efficient and quiet for daily driving, and spare parts are easy to find and affordable during . Although high-end models like the L5 may have imported tuning, most standard versions are fully domestically produced. This makes me trust the cost-performance ratio of domestic cars even more. Plus, the spacious and safe interior of Hongqi cars makes them ideal for family trips. In the long run, domestically produced engines improve stability, avoiding risks of foreign malfunctions, which boosts my confidence in Chinese manufacturing.

From a technical perspective, Hongqi engines are primarily domestically produced. FAW independently designs and manufactures the core components, achieving a high localization rate with localized material supply. This approach ensures better cost control and lower failure rates. Daily is simple and convenient, reducing environmental footprint. The domestic powertrain continues to optimize efficiency in line with national standards.

I chose the Hongqi car for the practicality of its domestically produced engine. As a family user, it's affordably priced, with engines manufactured in FAW's own factories ensuring quality. It drives comfortably and steadily, with ample space perfect for family outings with kids. Domestic components mean faster repairs and lower costs, eliminating the wait for imported parts. Overall, it's reliable and safe, showcasing the strength of national industry. domestic products gives peace of mind and supports local employment. The engine is efficient and fuel-saving, making daily commutes more economical and environmentally friendly.

For those concerned about environmental protection, the efficiency improvements in Hongqi's domestically produced engines are significant. FAW's own engines have reduced fuel consumption and emissions through technological upgrades, with some models like the EH7 electric vehicle using purely domestic power systems. This is greener and more sustainable than imported engines, aligning with China's environmental policies, and the future trend is towards clean energy. Domestic production also enhances recyclability, reducing the carbon footprint in the long term.
