Haval GW4N20 engine - Haval H6 3rd generation 22-23-24 & Haval Dargo

The GW4N20 engine is one of the flagship engines of Great Wall Motors' (GWM) new generation, manufactured through HYCET. It is a 2.0-liter turbocharged four-cylinder gasoline engine (2.0T/GDIT). Production began in 2020, and it is widely used in popular Haval models.

Here are the product description details and comprehensive technical specifications for this engine:

1. Basic technical specifications:

• Engine type: Inline 4-cylinder gasoline engine, turbocharged and with direct fuel injection technology (2.0 GDIT).
• Total capacity: 1,998 cc (2.0 liters).
• Horsepower (power): The power range varies depending on the calibration and version, between 192 and 241 horsepower (it often comes in 192, 211, or higher versions in hybrid and sports versions).
• Torque: ranges from 320 to 385 Newton-meters .
• Compression ratio: Relatively high to record higher efficiency (approximately 12:1 thanks to reliance on the Miller economic cycle).
• Engine weight: approximately 157 kg (with basic accessories).
• Emission standards: Compliant with Euro 5 and Euro 6 standards.

2. Key technologies and features:

• Miller Cycle: The engine features a design that operates on the Miller Cycle to significantly improve fuel efficiency and reduce emissions compared to previous generations of 2.0-liter engines.
• Direct fuel injection: to ensure more accurate and efficient combustion inside the cylinder chambers.
• Reliability and weight reduction: It relies on a block made of aluminum to reduce overall weight and increase vehicle responsiveness.
• Hybrid system: This engine is designed to be compatible with modern drive systems and advanced transmissions (such as 9-speed DCT transmissions in their various regular and hybrid 9HDCT versions) to maximize fuel efficiency.

3. Compatibility (most prominent cars that use it):

The GW4N20 engine is fitted to a number of popular SUVs and crossovers from Great Wall and Haval, including:

• Haval H6 (3rd Generation) Model 22-23-24
• Haval Dargo / Big Dog
• Haval F7 / F7x (2nd Generation)
• Haval H7
• Other models within the GWM range and some pickup versions and their alternatives are designed for city and off-road use.

4. Maintenance requirements and recommended oils:

• Recommended engine oil type: 0W-20 (with approved high-quality viscosity grades).
• Oil tank capacity: approximately 5.0 liters.
• Preferred fuel type: High octane gasoline (95 or 98 is recommended to maintain performance efficiency and avoid any explosive/tank weather in the cylinders due to the high compression ratio).
