Overview
The Cummins ISLe310 is a 8.9 L 6-cylinder Cummins diesel engine supplied in 4 factory ratings from 306 hp (228 kW) to 306 hp (228 kW). Every rating listed on this page is a complete engine for on-highway duty, not a generator set, and each unit ships with its serial number recorded against the specification sheet that applies to it.
Ratings in this family differ in rated speed, peak torque and emissions tier rather than in displacement or cylinder count, so the choice between them is a duty-matching question. The specifications panel and the per-rating entries on this page are generated from the same source data, so a rating quoted here can be matched directly against a delivery document.
Specifications
The specifications panel lists the family-level values that are common to every ISLe310 rating, including the 8.9 L displacement and the inline 6-cylinder layout. Ratings that share displacement and cylinder count but differ in output are listed individually in the model selection section.
Model Selection: ISLe310 Ratings
Each entry in this section is one rating of the Cummins ISLe310. The rated power is the output at the stated speed; the peak torque figure is the value the rating develops at the lower speed shown, which is what normally decides whether a rating suits a given machine. Each rating carries a stable anchor, so a single rating can be linked or quoted directly.
ISLe310 30
ISLe310 30 — rated 228 kW (306 hp) at 2100 rpm; peak torque 1200 N·m at None rpm; emissions EuroIII.
ISLe310 40
ISLe310 40 — rated 228 kW (306 hp) at 2100 rpm; peak torque 1200 N·m at 1400 rpm; emissions EuroIV.
ISLe310 31
ISLe310 31 — rated 228 kW (306 hp) at 2200 rpm; peak torque 1200 N·m at None rpm; emissions EuroIII.
ISLe310 41
ISLe310 41 — rated 228 kW (306 hp) at 2100 rpm; peak torque 1200 N·m at None rpm; emissions EuroIV.
Applications
ISLe310 engines in this family are normally specified for on-highway work.
On-highway: ratings are selected against the gross vehicle weight, the intended road speed and the emissions standard that applies in the destination market.
Emissions: the ratings listed here carry EuroIII or EuroIV. Where a market imposes a different standard, confirm the tier before ordering, because the same model number can be built to more than one tier.
Verification, Documentation and Ordering
Each engine is offered with nameplate verification + load-test record per serial number. That means the model and rating printed on the engine nameplate can be checked against the record issued for that serial number before shipment, which is the point most buyers of re-rated or re-exported engines want covered.
To receive a quotation, send the exact rating from the matrix above (for example ISLe310 41), the machine or application it will drive, the quantity, and the destination port. If the rating you need is not listed, send the model and the required output and we will confirm whether it belongs to this family or to a neighbouring one.
Buyer tip: Send your ISLe310 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What displacement and cylinder count does the ISLe310 use?
Every rating in this family shares the same 8.9 L displacement and inline 6-cylinder, 4-cycle configuration. Ratings differ in output, rated speed and emissions tier rather than in the base engine.
What is the difference between ISLe310 31 and ISLe310 41?
ISLe310 31 is rated 228 kW (306 hp) at 2200 rpm with peak torque of 1200 N·m, while ISLe310 41 is rated 228 kW (306 hp) at 2100 rpm with 1200 N·m. They use the same base engine; the higher rating is the one to specify when the driven load needs the extra torque at the lower speed.
Which emissions tiers are available for the ISLe310?
The ratings on this page are listed as EuroIII and EuroIV. Emissions tier is part of the rating definition, so state the tier your market requires when you request a quotation.
How is a ISLe310 rating ordered?
Send the exact rating shown in the model selection table, the application it will drive, the quantity and the destination port. The engine is then quoted against that rating and confirmed against its nameplate and load-test record.
