Maximum power: 120 kW/3600 rpm
Maximum torque: 400 N·m /1500-2500 rpm
The GW4N20 is a highly advanced engine developed by GWM (Great Wall Motors), featuring cutting-edge technologies aimed at enhancing performance, fuel efficiency, and emissions control. The engine is equipped with an electronic water pump and electronic thermostat, which are crucial for more intelligent thermal management. These components allow for more flexible control by the ECU, improving fuel efficiency by not directly consuming engine power, and represent the future direction of engine technology.
Key highlights of the GW4N20 engine include its thermal efficiency of 38.3%, which is comparable to some of the best engines in the world. It generates a maximum power output of 180 kW at 5500-6000 RPM and a maximum torque of 385 Nm at 1750-4000 RPM. The engine uses advanced technologies such as a 350-bar central direct injection system and a Miller cycle to optimize combustion efficiency, reducing fuel consumption and emissions.
The GW4N20 engine is also designed to meet stringent emission regulations, including China VI and Euro VI standards. Additionally, it is lighter than previous versions due to innovations like a combined hollow camshaft and sodium-filled valves, which reduce overall engine weight by 10%. This makes it a top performer in terms of both power and environmental standards.
