Is the 4A15J1 Engine Japanese Technology?
2 Answers
4A15J1 engine is not Japanese technology. Here is the relevant introduction of the 4A15J1 engine: 1. The 4A15J1 engine is domestically produced, developed and manufactured independently by GAC Trumpchi. It is a 1.5-liter turbocharged engine designed to fully replace the previous generation 4A15M1 engine; 2. The 4A15J1 engine has a maximum horsepower of 169Ps, a maximum power of 124Kw (maximum power speed 5000rpm), and a maximum torque of 265 N·m (maximum torque speed range is 1700-4000rpm); 3. Its biggest advantage is that it meets the China VI emission standards, and it is also one of the first domestically produced engines to meet the China VI emission standards.
As a long-time automotive engine enthusiast, I can definitively say that the 4A15J1 is our China's own technology. This 1.5T engine is GAC Trumpchi's self-developed flagship product, first equipped on the 2016 GS4 model. Although the '4A' prefix might make people associate it with Mitsubishi's 4A9 series, its cylinder block structure and combustion system are actually completely newly designed. It adopts direct injection technology with a maximum output of 169 horsepower and is equipped with Bosch high-pressure fuel injectors. I remember the R&D team spent three years conducting durability tests, specifically optimizing low-speed torque performance, making it particularly responsive in urban driving conditions. Currently, it powers GAC Trumpchi's main models like the GS4 and GA6, delivering performance fully comparable to Japanese engines in the same class while maintaining fuel consumption around 7 liters per 100km.
