Core Technical Features & ISLe290-30 Specifications
Euro III & Bosch Common Rail System
The DCEC ISLe290-30 diesel engine uses a Bosch high‑pressure common rail electronic fuel injection system, which ensures precise fuel control, stable combustion and low emissions. It fully meets Euro III standards and is widely compatible with older and upgraded truck platforms. With a rated power of 290HP and optimized torque output, the engine provides strong climbing and continuous operation capacity for heavy vehicles.
High‑Altitude & Low‑Temperature Adaptability
A major advantage of the Cummins ISLe290-30 engine is its strong environmental adaptability. It can maintain stable power output at 4500m high altitude without obvious power attenuation. At the same time, the optimized starting system supports reliable cold start at ‑12°C, making it suitable for plateau, cold northern regions and mountainous transportation.
Power, Torque & Fuel Consumption
The ISLe290-30 technical specifications show a maximum torque over 1050N·m, with a fuel consumption rate as low as 210g/kW·h, making it one of the most economical choices in the 290HP power segment. The engine uses a waste‑gated turbocharger, 24V electrical starting system, 706kg net weight and 11.1L coolant volume, all designed for long‑term heavy‑duty use. The Cummins ISLe290 torque and power curve is smooth and provides sufficient reserve power at medium and low speeds.
