Overview
The Cummins EQB125 is a 3.9 L 4-cylinder Cummins diesel engine supplied in 1 factory rating from 123 hp (92 kW) to 123 hp (92 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 EQB125 rating, including the 3.9 L displacement and the inline 4-cylinder layout. Ratings that share displacement and cylinder count but differ in output are listed individually in the model selection section.
Model Selection: EQB125 Rating
Each entry in this section is one rating of the Cummins EQB125. 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.
EQB125-20
EQB125-20 — rated 92 kW (123 hp) at 2800 rpm; peak torque 410 N·m at 1500 rpm; emissions EuroII.
Applications
EQB125 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 EuroII. 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 EQB125-20), 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 EQB125 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What displacement and cylinder count does the EQB125 use?
Every rating in this family shares the same 3.9 L displacement and inline 4-cylinder, 4-cycle configuration. Ratings differ in output, rated speed and emissions tier rather than in the base engine.
Which emissions tiers are available for the EQB125?
The ratings on this page are listed as EuroII. Emissions tier is part of the rating definition, so state the tier your market requires when you request a quotation.
How is a EQB125 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.
At what speed is the EQB125 rated?
The ratings on this page are governed at 2800 rpm. Rated speed fixes the speed the driven machine sees through its gearing, so confirm the governed speed before ordering rather than relying on the power figure alone.
What peak torque does the EQB125 develop?
The rating listed here develops 410 N·m of peak torque at the lower speed shown.
Is the EQB125 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.
