What is the difference between Aowei 11-liter 420 and 460?
2 Answers
Aowei 11-liter 420 and 460 mainly differ in horsepower. The 11-liter engine has different horsepower stages. The Xichai Aowei 11-liter 6DM engine covers 390/420/460 horsepower. The displacement is the same, but the horsepower varies. Similarly, the Dongfeng Tianlong Renault DCI-11-liter engine horsepower ranges from 340/350/375/385/420 horsepower. Classification of engines: Depending on the power source, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. Principle of engines: Common gasoline and diesel engines are both reciprocating piston internal combustion engines, converting the chemical energy of fuel into the mechanical energy of piston motion to output power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have lower manufacturing costs; diesel engines have a higher compression ratio, better thermal efficiency, and superior economic and emission performance compared to gasoline engines.
As a guy who often drives trucks, I think the main difference between the Aowei 11-liter 420 and 460 lies in their power. The 420-horsepower version is particularly fuel-efficient when hauling regular cargo on flat roads. For someone like me who does urban distribution, it can save hundreds of yuan in fuel costs per month. On the other hand, the 460-horsepower model has more strength, making it suitable for steep climbs or heavy loads, such as transporting ore in mountainous areas—it starts faster and has much stronger power. The 460 version consumes a bit more fuel, which can be wasteful if the workload is light. There’s also a significant price difference, with the 420 being more affordable. However, the 460 has ample power reserves, and under long-term harsh road conditions, engine wear might actually be less. Overall, it depends on your needs. If you ask me, prioritize your load requirements rather than just focusing on horsepower numbers.
