1. Basic parameters
Engine type: air-cooled, turbocharged, direct-injection diesel engine
Cylinder arrangement: V-type 8-cylinder (V8)
Displacement: 12.76 liters (about 1.6L per cylinder, total displacement is calculated by cylinder diameter × stroke)
Valve structure: 2 valves per cylinder (2V)
Power range: usually 250-350 horsepower (184-257 kW)
Torque peak: about 900-1200 N·m (explosion in low speed range, suitable for heavy load).
2. Core features
Air-cooled design:
No cooling liquid system, relying on forced air cooling (fan + deflector), adapting to harsh environments such as high temperature and dust (such as mines and deserts).
Easy maintenance, avoiding freezing cracks or coolant leakage.
Turbocharger:
Equipped with exhaust gas turbocharger to improve intake efficiency and improve power performance in plateau or high-load conditions.
Fuel system:
Mechanical direct injection, good fuel economy, strong adaptability to oil products.
3. Typical applications
Engineering machinery: mining dump trucks, loaders, bulldozers (such as early Sinotruk mining vehicles).
Special vehicles: military armored vehicles, oil field operation vehicles (due to high reliability of air cooling).
Generators: as industrial backup power supply units.
4. Maintenance and advantages
Advantages:
Sturdy structure, air cooling design reduces failure points, suitable for extreme environments.
V8 layout has good balance, and vibration control is better than inline multi-cylinder engines.
Note:
Regularly clean the cooling air duct to prevent dust accumulation from affecting cooling efficiency.
Old models need to pay attention to the status of the turbocharger and injection system.
