| Your Pain Point | This Engine Fixes It |
|---|---|
| "My old engine can’t handle 49-ton loads on slopes" | 2000 N·m peak torque: pulls full containers up 15% grades without lag |
| "Fuel costs eat into my profits" | 8% lower fuel consumption vs. competitors: save $1,200/year per vehicle |
| "Frequent maintenance delays my fleet" | 2000-hour service interval: 3x fewer downtime days than standard engines |
| "I need to pass EU/Middle East emissions tests" | Euro VI / National VI certified: no extra mods for global markets |
Type: Inline 6-cylinder turbocharged diesel
Power: 300–500 HP (tunable to your vehicle’s needs)
Durability: Reinforced cylinder block → 10,000+ hours before major overhauls
Perfect for CAMC H7 tractors, long-haul trucks, or mining machinery
Emissions: Euro VI / China VI (compliant with EU, GCC, SASO rules)
Compatibility: Factory-fit for CAMC vehicles; custom brackets for other brands
Support: 20+ overseas parts warehouses → 3–7 day delivery for filters/gaskets
| Cost Type | Savings vs. Standard Engines |
|---|---|
| Fuel | $1,200/year/vehicle |
| Maintenance | $800/year/vehicle (fewer services) |
| Downtime | 15+ extra working days/year |
Fleet Owners: Power CAMC H7 tractors for Middle East/African long-haul routes
Machinery Operators: Equip excavators/loaders for mining/infrastructure projects
Vehicle Builders: Custom-fit to buses/trucks for regional markets
"We put this engine in 12 CAMC H7s for our Nigeria-Liberia line. It handles unpaved roads and 49-ton loads easily. Fuel savings? We paid for 2 engines in 10 months. Maintenance? Only 1 service every 50,000 km — game-changer."— Kola, West Africa Cargo Fleet
