4 Cylinders Tier 3 B5.9 Engine QSB5.9 Diesel Engine For Constructions Machinery

Key Features of QSB5.9 diesel engine :

QSB5.9 uses forged steel crankshaft/camshaft and high-strength cast iron cylinder body, with good rigidity and high pressure resistance. Wet cylinder liner, with low overhaul cost, suitable for long-term heavy load working conditions.

The engine uses high-pressure common rail and electronic control injection technology, which ensures more complete combustion, high low-speed torque, and good transient response.

The torque coverage is 650-820 N · m, and peak torque can be output at 1400-1500 rpm, suitable for heavy-duty starting. The fuel consumption rate is low, with a typical operating condition of about 210-220 g/kWh.

Application of QSB5.9 engine:
