EURO I 4DW91-50G

The 4DW91-50G represents a proven workhorse in FAW’s industrial engine lineup. After years of field testing across Southeast Asian markets, this naturally aspirated diesel has earned its reputation for getting the job done without fuss.

Built for Real-World Applications

This 2.54-liter powerplant delivers 37 kilowatts at 2650 rpm – right where forklifts need it most. The peak torque of 149 Newton-meters kicks in at just 1800 rpm, which means operators get strong pulling power without hammering the throttle. That’s critical when you’re maneuvering loaded pallets through tight warehouse spaces or feeding production lines.

Simple Design, Smart Engineering

The inline four-cylinder configuration keeps things straightforward. Each cylinder measures 90mm across with a 100mm stroke, creating that sweet spot between low-end grunt and smooth operation. Direct injection ensures fuel goes exactly where it needs to, when it needs to. No complex turbochargers or intercoolers to worry about – just reliable mechanical injection that warehouse mechanics can service with basic tools.

Cooling That Works

The water-cooling system handles the heat load efficiently, even in humid coastal warehouses or dusty inland depots. The oversized radiator core and high-flow water pump keep temperatures stable during those long shifts. Regular coolant changes and simple thermostat checks are all you need to keep it running cool.

Meeting EURO I Standards

While newer emissions standards exist, EURO I compliance hits the practical sweet spot for many industrial applications. You get cleaner combustion than older designs without the complexity of EGR valves, DPF filters, or AdBlue systems. This means lower operating costs and fewer things to break down when you need the machine running.

Heritage of Reliability

FAWDE has been building engines since 1943. That’s eight decades of learning what breaks and fixing it. The 4DW91 series benefits from this accumulated knowledge – strengthened connecting rods, improved head gasket designs, and optimized piston rings that came from millions of operating hours in the field.

Service and Support Network

Through our exclusive distribution agreement with FAW Jiefang Wuxi Diesel Engine Plant, we maintain comprehensive parts inventory. Common wear items like filters, belts, and gaskets ship same-day. Major components typically arrive within 72 hours. Our technicians receive direct factory training annually, ensuring they know these engines inside and out.
