GW2.8TC engine is a classic inline 4-cylinder turbocharged diesel engine independently developed by Great Wall Motors. Known for its strong low-torque output, excellent durability and outstanding fuel economy, it is widely used in many tough pickup trucks and SUV models such as Great Wall Wingle 5, Wingle 6, Haval H3 and Haval H5. It is also the preferred power core for commercial vehicle modification and special operation vehicles. Equipped with advanced high-pressure common rail fuel injection technology and exhaust gas turbocharging system, this 2.8L displacement engine can easily cope with high-intensity needs such as heavy-load transportation, off-road driving and complex road operation, making it an all-round diesel power unit that balances commercial practicality and off-road passability.
II. Core Advantages
1. Brand-New Assembly, Quality Traceability
This product is accurately assembled with brand-new original accessories, strictly following Great Wall Motors' original production standards and assembly processes. From core power components such as cylinder block, cylinder head and crankshaft to detailed accessories such as gaskets and fasteners, all have undergone multiple rounds of rigorous quality screening and precision verification. This ensures that the assembly accuracy and component fit of each GW2.8TC engine are completely consistent with the original factory standards, fundamentally eliminating problems such as renovation, patchwork and mismatched accessories, replicating the reliable performance of the original model, and providing users with solid and stable power guarantee.
2. Professional Hot Break-In Test, Stable Performance
Each GW2.8TC engine undergoes a standardized professional hot break-in test before leaving the factory. The entire test simulates the actual working conditions of the engine: first, it idles and preheats at a low speed of 500-800 rpm, then gradually increases the speed to the normal working range, and runs continuously for a specified period under set temperature and load conditions. This test can comprehensively verify the fitting accuracy of various engine components, sealing performance, oil lubrication cycle effect and power output stability, especially conducting targeted verification for the turbocharging system and high-pressure common rail system of the GW2.8TC engine. Only engines that meet all indicators can be delivered, which effectively reduces the risk of initial operation failures and further enhances the service life and adaptability of the engine to harsh working conditions.
3. Comprehensive Warranty Service, Worry-Free After-Sales
We provide a one-year comprehensive warranty service for all GW2.8TC engine products. During the warranty period, if the engine malfunctions due to manufacturing defects or assembly quality problems, we will immediately activate a fast-response after-sales mechanism to provide users with professional services such as free maintenance and replacement of original accessories. The complete warranty system and experienced after-sales team effectively solve users' usage concerns, allowing every user to enjoy a worry-free usage experience whether for commercial heavy-load transportation or off-road outdoor operations.
4. Strong Power, Economic and Efficient
The GW2.8TC engine has a displacement of 2.8L, with a maximum output power of 70kW (about 95ps) and a peak torque of 225N·m. The maximum torque can be achieved in the wide speed range of 1600-2600 rpm, with abundant and continuous low-torque output, which is very suitable for heavy-load starting and off-road escape scenarios. Adopting a high-strength cast iron cylinder block design, the engine has excellent impact resistance and heat resistance, and can adapt to complex and harsh operating environments. Meanwhile, its equipped high-pressure common rail fuel injection technology accurately controls fuel atomization, effectively optimizing fuel consumption. The comprehensive working condition fuel consumption is only 7.5-8.5 liters per 100km, showing excellent economy among diesel engines of the same displacement. The emission indicators meet the National IV environmental standards, balancing power performance and environmental protection requirements.
