Heavy-Duty 64kW Backup – Engineered for 240V Applications

When the power goes out and you need serious backup, the EMEAN EM-W88 delivers a solid 64kW (80kVA) of prime power, backed by an 85kW WEICHAI WP4.1D95E201 turbocharged diesel engine. With a wide voltage range from 110V to 660V—including standard 240V configurations—this is a 240 volts generator that works seamlessly with North American electrical systems. Whether you are protecting a large home, a farm, or a small business, this generator keeps your 240V appliances, tools, and equipment running when you need them most.

The EM-W88 is more than just another 240 volts 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 70.4kW (88kVA), 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 full-load fuel consumption of just 17.2 L/h, making it a practical choice for extended backup power.

Powered by WEICHAI – The 4.087L Workhorse

At the heart of this 240 volts generator lies the WEICHAI WP4.1D95E201, a 4-cylinder, 4.087-liter turbocharged 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 1.382 MPa and a mean piston speed of 7.08 m/s—a well-balanced figure that promotes long engine life while delivering robust power.

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-W88 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 – When You Need It Most

A 240 volts generator is only useful if it starts when you need it. The WP4.1D95E201 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-W88 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. When a winter storm hits, this 240 volts generator delivers the reliable starting performance you need to keep your family or business running.

Engineered for Quiet, Efficient Operation

The EM-W88 features a soundproof canopy lined with sound-reducing foam, making it a 240 volts generator that respects both residential and commercial environments. The industrial silencer and modular ventilation design further reduce noise levels, while the all-metal canopy parts are powder-coated for durability and corrosion resistance.

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 6.7 m³/h, and the system holds 9.4L of coolant. At rated conditions, the cooling system removes 37.9 kJ/s of heat while the exhaust carries away 72.8 kJ/s, ensuring stable operating temperatures even during extended run times.

Clean, Efficient Combustion

The turbocharged WP4.1D95E201 draws 464 kg/h of air at rated conditions and 491 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.

Complete Generator Set Features

The EM-W88 generator set is built around the WEICHAI engine and features a VG-224F brushless alternator with Class H insulation, an automatic voltage regulator (AVR), and IP23 protection. The alternator is available from leading brands including Stamford, Leroy-Somer, or Marathon. The digital control panel (Smartgen or Deep Sea) includes auto-protection features such as overcurrent shutdown and low oil pressure alarm.
