Heavy-Duty 80kW Power – Engineered for Automatic Starting Reliability

When the grid goes down, you need a generator that not only delivers serious power but also starts the moment it‘s needed—without you having to lift a finger. The EMEAN EM-W110 provides a solid 80kW (100kVA) of prime power, backed by a 90kW WEICHAI WP4.1D100E200 turbocharged and intercooled diesel engine. Equipped with advanced digital control panels from Smartgen or Deep Sea, this is a self starter generator that automatically detects power outages and initiates startup within seconds—giving you true peace of mind during emergencies.

The EM-W110 is more than just another self starter generator—it is a thoughtfully engineered power system that combines proven WEICHAI diesel technology with intelligent auto-start capabilities. 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 1500 RPM (50Hz) with a fuel consumption of just 202.4 g/kW.h, making it a cost-effective choice for extended backup power.

True Self-Starting Capability – When You Need It Most

What makes the EM-W110 a self starter generator you can depend on is its fully integrated automatic starting system. The digital controller—available from industry leaders Smartgen or Deep Sea—continuously monitors utility power. When an outage is detected, the self starter generator engages the 24V electric starter system (featuring a 4.5kW starter motor and 55A battery charging alternator) to crank the engine automatically.

Once the engine reaches rated speed and voltage stabilizes, the self starter generator automatically transfers the load from the grid to the generator through an optional Automatic Transfer Switch (ATS). When utility power is restored, the self starter generator shuts down automatically and transfers back—all without human intervention. This makes the EM-W110 an ideal self starter generator for unattended installations, remote sites, and homes where someone may not be present during an outage.

Powered by WEICHAI – The 4.087L Powerhouse

At the heart of this generator lies the WEICHAI WP4.1D100E200, 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 1.756 MPa—significantly higher than many competitors—and a mean piston speed of 5.9 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 157.8°C down to just 51.2°C, with a pressure drop of only 3.4 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 300–500 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 WP4.1D100E200 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 and Europe, 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 55A 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 WP4.1D100E200 delivers impressive efficiency. At 202.4 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 8.5 m³/h, and the system holds 9.4L of coolant. At rated conditions, the cooling system removes 50.8 kJ/s of heat while the exhaust carries away 61.5 kJ/s, ensuring stable operating temperatures even during extended run times.

Clean, Efficient Combustion

The turbocharged and intercooled WP4.1D100E200 draws 445 kg/h of air at rated conditions and 492 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.
