Overview
The Cummins 4BTAA3.9 is a 3.9 L 4-cylinder Cummins diesel engine supplied in 6 factory ratings from 80 hp (60 kW) to 130 hp (97 kW). Every rating listed on this page is a complete engine for construction 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 4BTAA3.9 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: 4BTAA3.9 Ratings
Each entry in this section is one rating of the Cummins 4BTAA3.9. 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.
4BTAA3.9-C80
4BTAA3.9-C80 — rated 60 kW (80 hp) at 2200 rpm; peak torque 370 N·m at 1300 rpm; emissions Euro II.
4BTAA3.9-C100
4BTAA3.9-C100 — rated 74 kW (100 hp) at 2200 rpm; peak torque 400 N·m at 1500 rpm; emissions Euro II.
4BTAA3.9-C110
4BTAA3.9-C110 — rated 82 kW (110 hp) at 2200 rpm; peak torque 480 N·m at 1400 rpm; emissions Euro II.
4BTAA3.9-C125
4BTAA3.9-C125 — rated 93 kW (125 hp) at 2200 rpm; peak torque 480 N·m at 1300 rpm; emissions Euro II.
4BTAA3.9-C115
4BTAA3.9-C115 — rated 95 kW (127 hp) at 2200 rpm; peak torque 530 N·m at 1400 rpm; emissions Euro II.
4BTAA3.9-C130
4BTAA3.9-C130 — rated 97 kW (130 hp) at 2200 rpm; peak torque 510 N·m at 1400 rpm; emissions Euro II.
Applications
4BTAA3.9 engines in this family are normally specified for construction work.
Construction duty: the ratings with the higher peak torque are the ones normally quoted for loaders, dozers and haul trucks, where the engine has to hold torque under a sudden increase in load at low ground speed.
Duty cycle: the lower ratings in the same family are used where the duty cycle is closer to continuous and the installed package limits the cooling or the coupling that can be fitted.
Emissions: the ratings listed here carry Euro II. 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 4BTAA3.9-C130), 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 4BTAA3.9 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What is the power range of the 4BTAA3.9?
The 6 ratings listed on this page run from 80 hp (60 kW) to 130 hp (97 kW).
What displacement and cylinder count does the 4BTAA3.9 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.
What is the difference between 4BTAA3.9-C115 and 4BTAA3.9-C130?
4BTAA3.9-C115 is rated 95 kW (127 hp) at 2200 rpm with peak torque of 530 N·m, while 4BTAA3.9-C130 is rated 97 kW (130 hp) at 2200 rpm with 510 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 4BTAA3.9?
The ratings on this page are listed as Euro II. Emissions tier is part of the rating definition, so state the tier your market requires when you request a quotation.
How is a 4BTAA3.9 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.
