Technical Mastery: ISLe300-30 Specifications and Data
The ISLe300-30 specifications represent the pinnacle of the Cummins 8.9L series. With a rated power of 221KW (300HP) at 2100RPM, this engine is the preferred choice for heavy trucks and large passenger buses.
Torque and Power Curve Analysis
A critical factor for fleet operators is the Cummins ISLe300 torque and power curve data. This engine delivers a massive 1250N·m of low-speed torque, ensuring superior climbing ability and heavy-load starting performance. Compared to lower-rated models, the ISLe300-30 vs ISLe290-30 performance comparison shows a significant advantage in sustained pulling power under full-load conditions.
Fuel Efficiency with Bosch Common Rail
The Bosch common rail ISLe300-30 fuel-efficient engine technology allows for precise injection timing. This results in an impressive ISLe300-30 Euro III engine 195g/kW·h fuel consumption rate. For long-haul logistics, this efficiency translates into thousands of dollars in annual fuel savings per vehicle.
4500m High-Altitude Performance
Oxygen-thin environments can cripple standard diesel engines. The ISLe300-30 engine for 4500m high altitude features an advanced waste-gated turbocharger that compensates for air density, maintaining 300HP even in mountainous regions. This makes it the ideal Cummins ISLe300 engine for heavy duty truck operations in high-plateau areas.
Reliable -12°C Cold Start
Equipped with a robust 24V electrical starting system, our -12°C cold start ISLe300-30 diesel engine ensures your fleet remains operational in frigid temperatures. This reliability is why HekoPower is a trusted genuine ISLe300-30 engine exporter to northern climates.
Fleet Upgrades and Compatibility
Are you looking to modernize your current fleet? Many customers choose to replace Cummins C8.3 with ISLe300-30 8.9L upgrade units to take advantage of electronic controls and better emissions standards.
Dongfeng Truck and Bus Applications
The ISLe300-30 engine for Dongfeng trucks is a "plug-and-play" solution for many heavy-duty models. It also serves as a reliable ISLe300 engine for bus and commercial vehicles, offering the smooth power delivery required for passenger comfort and heavy-duty towing.
Logistics and Shipping Specs
For international buyers, the ISLe300-30 engine weight and shipping dimensions are crucial. The engine has a 710kg net weight specification, and HekoPower provides secure, export-grade packaging to ensure the ISLe300-30 engine 10-business-day lead time is met with the engine arriving in pristine condition.
ISLe300-30 vs. ISLe310: Understanding the Differences
A common question among fleet managers is the difference between the ISLe300-30 and the ISLe310. While both engines share the same robust 8.9L block, the primary difference lies in the power tuning and torque curves.
The ISLe300-30 is tuned for a balance of fuel economy (195g/kW·h) and sufficient torque (1250 N·m) for standard heavy-duty haulage. The ISLe310 offers slightly higher horsepower for more demanding loads. However, for most Dongfeng truck applications, the 300HP variant offers the best "Total Cost of Ownership" due to its proven longevity and optimal fuel efficiency.
