Overview
The Cummins 6BT5.9 is a 5.9 L Cummins diesel engine supplied in 2 factory ratings from 115 hp (86 kW) to 115 hp (86 kW). Every rating listed on this page is a complete engine for generator drive 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 6BT5.9 rating. Ratings that share displacement and cylinder count but differ in output are listed individually in the model selection section.
Model Selection: 6BT5.9 Ratings
Each entry in this section is one rating of the Cummins 6BT5.9. 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.
6BT5.9-G1
6BT5.9-G1 — rated 86 kW (115 hp) at None rpm; emissions 国二.
6BT5.9-G2
6BT5.9-G2 — rated 86 kW (115 hp) at None rpm; emissions 国二.
Applications
6BT5.9 engines in this family are normally specified for generator drive work.
Generator drive: ratings here are quoted at a fixed governed speed, and the engine is matched to the alternator frame and the prime/standby duty that the site actually needs.
Emissions: the ratings listed here carry 国二. 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 6BT5.9-G2), 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 6BT5.9 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What is the difference between 6BT5.9-G1 and 6BT5.9-G2?
6BT5.9-G1 is rated 86 kW (115 hp) at None rpm, while 6BT5.9-G2 is rated 86 kW (115 hp) at None rpm. 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 6BT5.9?
The ratings on this page are listed as 国二. Emissions tier is part of the rating definition, so state the tier your market requires when you request a quotation.
How is a 6BT5.9 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.
Is the 6BT5.9 a complete engine or a generator set?
Every entry on this page is a complete engine. Generator sets and packaged gen-sets are listed separately from this family and are not included here.
