C9 engine for crusher
Power architecture: inline 6-cylinder four-stroke turbocharged intercooler
Displacement: 8.8L
Bore × stroke: 112 × 152mm
Compression ratio: 17.5:1, suitable for lightweight and high-mobility scenarios
Intake method: air-to-air aftercooling
Fuel system: hydraulic electronic unit injection
Power coverage: rated power 260-450HP (194-336kW) @1800-2200RPM, peak torque 1600N·m@1400RPM, support transient response accuracy ±2%.
Fuel compatibility: electronically controlled high-pressure common rail (HEUI) system, injection pressure 1800bar, compatible with B20 biodiesel and fuel with sulfur content ≤500ppm.
C9 engine technical highlights
Modular design (length × width × height: 1.2 × 0.8 × 1.1m), weighing only 950kg, suitable for narrow cabins (such as fire pump trucks, compact generator sets).
Two-stage turbocharging (Holset HX52) + variable cross-section intercooler, power attenuation at 3000 meters above sea level <8%.
Low temperature optimization: integrated intake electric heating + cylinder preheating kit, -32℃ cold start time <15 seconds.
Anti-pollution design: two-stage fuel filtration (10μm pre-filtration + 4μm main filter element), fuel system life extended by 30% in muddy environment.
C9 engine application adaptation
Municipal emergency: drive fire pumps, emergency lighting vehicles, and achieve full power output within 30 seconds.
Agricultural mechanization: match combine harvesters and heavy tractors, oil consumption rate under farmland vibration conditions <0.1g/kWh.
Ship Auxiliary: As auxiliary engine for tugboats/yachts, it complies with SAE J1171 marine explosion-proof standards.
