Weifang 6R Series Engine

This series is a straight-six cylinder, four-stroke, forced water-cooled diesel engine with a firing order of 1-5-3-6-2-4. It has a compression ratio of 16:1 and a rated speed range of 1500/1800 rpm. It is suitable for medium and large power generator sets, construction machinery, and ship power, etc. The following are detailed introductions of three configurations:
1. R6105ZD Turbocharged Diesel Engine
Core Parameters
Type: Straight-six cylinder, four-stroke, forced water-cooled
Intake Method: Turbocharged
Cylinder Diameter × Stroke: 105mm × 125mm
Displacement: 6.49L
Rated Power / Speed:
84kW / 1500 rpm
94kW / 1800 rpm
Fuel Consumption Rate: ≤ 231g/kw.h
Exhaust Temperature: ≤ 600℃
Net Weight: 570kg
Lubrication Method: Pressure and Splash Combined
Starting Method: Electric Starting
Product Features: This is a basic turbocharged model of the series. The structure is mature and reliable, maintenance is convenient, and it is suitable for medium power generator sets and engineering equipment. The turbocharging technology optimizes combustion efficiency and the power output is stable. It is calibrated for generator sets at 1500 rpm and has strong load adaptability. It is a cost-effective choice for medium and large power backup power sources.
2. R6105AZLD Long Stroke Turbocharged Diesel Engine
Core Parameters
Type: Straight-six cylinder, four-stroke, forced water-cooled
Intake Method: Turbocharged
Cylinder Diameter × Stroke: 105mm × 130mm
Displacement: 6.75L
Rated Power / Speed:
110kW / 1500 rpm
125kW / 1800 rpm
Fuel Consumption Rate: ≤ 224g/kw.h
Exhaust Temperature: ≤ 600℃
Net Weight: 580kg
Lubrication Method: Pressure and Splash Combined
Starting Method: Electric Starting
Product Features: With a long stroke design, compared to R6105ZD, the displacement is increased by approximately 4%, and the power and economy are simultaneously optimized. The fuel consumption rate is reduced by about 3%, and the low-torque output is more abundant. It is suitable for medium and large power generator sets and heavy-duty construction machinery. The long stroke design enhances low-speed torque, making it more capable of coping with variable load conditions, while maintaining excellent fuel consumption control and lower long-term operating costs.
3. R6105IZLD Long Stroke Turbocharged Intercooled Diesel Engine
Core Parameters
Type: Straight-six cylinder, four-stroke, forced water-cooled
Intake Method: Turbocharged Intercooled
Cylinder Diameter × Stroke: 105mm × 135mm
Displacement: 7.1L
Rated Power / Speed:
132kW / 1500 rpm
145kW / 1800 rpm
Fuel Consumption Rate: ≤ 224g/kw.h
Exhaust Temperature: ≤ 600℃
Net Weight: 610kg
Lubrication Method: Pressure and Splash Combined
Starting Method: Electric Starting
Product Features: This is the top model of the series. It adopts long stroke + turbocharged intercooled technology, further increasing the displacement and significantly enhancing the power output. It is the most powerful among the three models of medium power. The intercooled technology effectively reduces the intake temperature, improves intake efficiency and combustion stability, and has a lower heat load. It can cope with long-term continuous heavy-load operation and is suitable for large power generator sets, industrial-level backup power sources, and ship power, etc. It balances power performance, reliability, and fuel economy.
