Heavy-Duty 120kW Power – Engineered for Instant, Effortless Starting

When the grid goes down and every second counts, you need a generator that fires up without hesitation—no complicated procedures, no frustrating delays. The EMEAN EM-W165 delivers a solid 120kW (150kVA) of prime power, backed by a 144kW WEICHAI WP6D158E201 turbocharged and intercooled diesel engine. With its advanced 24V electric starting system featuring a powerful 6kW starter motor and 35A battery charging alternator, this is an easy start generator that gets to work the moment you need it—turning the key or pressing the button is all it takes.

The EM-W165 is more than just another easy start 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 132kW (165kVA), 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 199.7 g/kW.h, making it a cost-effective easy start generator for extended backup power.

Powered by WEICHAI – The 6.75L Straight-Six Powerhouse

At the heart of this easy start generator lies the WEICHAI WP6D158E201, a 6-cylinder, 6.75-liter turbocharged and intercooled diesel engine with an inline configuration. With a bore and stroke of 105×130 mm and a compression ratio of 18:1, this larger-displacement platform delivers exceptional torque and thermal efficiency. The engine achieves a mean effective pressure of 1.422 MPa and a mean piston speed of 7.8 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 137.2°C down to just 51.7°C, with a pressure drop of only 0.4 kPa. The engine draws 714 kg/h of air at rated conditions, ensuring complete combustion and reduced emissions.

What truly sets this engine apart is its remarkable oil consumption ratio of just ≤0.2% of fuel consumption—significantly lower than the industry average. With an oil capacity of 16L, the EM-W165 is designed for extended service intervals that minimize downtime. The engine maintains oil pressure between 300–600 kPa at rated speed, with a low-pressure alarm and shutdown at 80 kPa to protect the engine from damage.

Built to Start in the Coldest Conditions – Effortlessly

An easy start generator is only as good as its ability to start when you need it most. The WP6D158E201 starts reliably down to 10°C without auxiliary starting devices, and with a preheater, it operates confidently down to -30°C. This exceptional cold-start capability makes the EM-W165 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 6kW starter motor and 35A battery charging alternator provide robust starting power that you can count on every time. When a winter storm hits, this easy start generator delivers the reliable starting performance you need to keep your family or business running.

Engineered for Quiet, Efficient Operation

The EM-W165 features a soundproof canopy lined with sound-reducing foam, making it an easy start 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 50°C ambient temperature, with a thermostat that begins opening at 76°C and reaches full opening at 90°C. Coolant flow is 13.3 m³/h, and the system holds 8L of coolant. At rated conditions, the cooling system removes 59.3 kJ/s of heat while the exhaust carries away 97.9 kJ/s, ensuring stable operating temperatures even during extended run times.

Clean, Efficient Combustion

The turbocharged and intercooled WP6D158E201 draws 714 kg/h of air at rated conditions and 758 kg/h at standby, ensuring complete combustion and reduced emissions. The exhaust system is designed with a maximum back pressure limit of 6±0.5 kPa, allowing for flexible exhaust routing without compromising performance. Maximum exhaust temperature is capped at 700°C before the turbocharger and 550°C after—indicating robust thermal design that protects turbocharger components over the long term.
