Heavy-Duty 80kW Backup Power – Engineered for Reliability and Value

When the grid goes down, you need a generator that delivers serious power without compromise—and at a price that makes sense for your budget. The EMEAN EM-W110 provides a solid 80kW (100kVA) of prime power, backed by a 105kW WEICHAI WP4.1D115E201 turbocharged and intercooled diesel engine. Whether you are protecting a large home, a farm, a retail store, or a small business, this sale diesel generator offers the perfect balance of performance, efficiency, and affordability.

The EM-W110 is more than just another sale diesel generator—it is a thoughtfully engineered power system that combines proven WEICHAI diesel technology with modern control features and a soundproof canopy for quiet operation. With a standby rating of 88kW (110kVA), this unit provides ample headroom for starting motors with high inrush currents and handling temporary load surges. The generator operates at 1800 RPM (60Hz) with a fuel consumption of just 207.0 g/kW.h, making it a cost-effective sale diesel generator for extended backup power.

Powered by WEICHAI – The 4.087L Powerhouse

At the heart of this sale diesel generator lies the WEICHAI WP4.1D115E201, a 4-cylinder, 4.087-liter turbocharged and intercooled diesel engine with an L-type cylinder arrangement. With a bore and stroke of 105×118 mm and a compression ratio of 17.5, this larger-displacement platform delivers exceptional torque and thermal efficiency. The engine achieves a mean effective pressure of 1.716 MPa and a mean piston speed of 7.08 m/s—a well-balanced figure that promotes long engine life while delivering robust power.

The intercooling system is particularly impressive: at rated conditions, the intercooler reduces intake air temperature from 189.4°C down to just 50.7°C, with a pressure drop of only 5 kPa. This efficient charge-air cooling enables higher power output, cleaner combustion, and more stable operation.

What truly sets this engine apart is its remarkable oil consumption ratio of just 0.1% of fuel consumption—significantly lower than the industry average. With an oil capacity of 12L (low) to 14L (high), the EM-W110 is designed for extended service intervals that minimize downtime. The engine maintains oil pressure between 250–500 kPa at rated speed, with a low-pressure alarm at 100 kPa to protect the engine from damage.

Built to Start in the Coldest Conditions

Cold weather reliability sets this generator apart from many competitors. The WP4.1D115E201 starts reliably down to 15°C without auxiliary starting devices, and with a preheater, it operates confidently down to -25°C. This exceptional cold-start capability makes the EM-W110 a practical choice for installations across North America, where winter storms can knock out the power grid for days.

The 24V starting circuit is engineered with a maximum resistance of just 4 mΩ and uses 50 mm² wiring, ensuring ample current delivery to the starter even in the coldest conditions. A 4.5kW starter motor and 18A battery charging alternator provide robust starting power that you can count on every time.

Fuel Efficiency That Lowers Your Operating Costs

Fuel consumption is a critical consideration for any generator owner, and the WP4.1D115E201 delivers impressive efficiency. At 207.0 g/kW.h, this translates to predictable operating costs and less frequent refueling compared to many competitors in this power range.

The engine’s thermal management is equally impressive. The closed-loop water cooling system is rated for operation up to 40°C ambient temperature, with a thermostat that begins opening at 76°C and reaches full opening at 89°C. Coolant flow is 10.3 m³/h, and the system holds 9.4L of coolant. At rated conditions, the cooling system removes 48.6 kJ/s of heat while the exhaust carries away 77.5 kJ/s, ensuring stable operating temperatures even during extended run times.

Clean, Efficient Combustion

The turbocharged and intercooled WP4.1D115E201 draws 677 kg/h of air at rated conditions and 712 kg/h at standby, ensuring complete combustion and reduced emissions. The exhaust system is designed with a maximum back pressure limit of 10 kPa, allowing for flexible exhaust routing without compromising performance. Maximum exhaust temperature is capped at 560°C—significantly lower than many competitors—indicating robust thermal design that protects turbocharger components over the long term.
