Overview
The Cummins QSZ13 is a 13 L Cummins diesel engine supplied in 7 factory ratings from 440 hp (328 kW) to 687 hp (512 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 QSZ13 rating. Ratings that share displacement and cylinder count but differ in output are listed individually in the model selection section.
Model Selection: QSZ13 Ratings
Each entry in this section is one rating of the Cummins QSZ13. 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.
QSZ13-G6
QSZ13-G6 — rated 328 kW (440 hp) at 374 rpm; emissions 国三/欧三.
QSZ13-G7
QSZ13-G7 — rated 367 kW (492 hp) at 419 rpm; emissions 国三/欧三.
QSZ13-G2
QSZ13-G2 — rated 400 kW (536 hp) at 440 rpm; emissions 国二.
QSZ13-G5
QSZ13-G5 — rated 411 kW (551 hp) at 470 rpm; emissions 欧二.
QSZ13-G3
QSZ13-G3 — rated 450 kW (603 hp) at 470 rpm; emissions 国二.
QSZ13-G10
QSZ13-G10 — rated 463 kW (621 hp) at 509 rpm.
QSZ13-G11
QSZ13-G11 — rated 512 kW (687 hp) at 563 rpm.
Applications
QSZ13 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 国三/欧三 or 国二 or 欧二. 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 QSZ13-G11), 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 QSZ13 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What is the power range of the QSZ13?
The 7 ratings listed on this page run from 440 hp (328 kW) to 687 hp (512 kW), at governed speeds between 374 and 563 rpm.
What is the difference between QSZ13-G10 and QSZ13-G11?
QSZ13-G10 is rated 463 kW (621 hp) at 509 rpm, while QSZ13-G11 is rated 512 kW (687 hp) at 563 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 QSZ13?
The ratings on this page are listed as 国三/欧三 and 国二 and 欧二. Emissions tier is part of the rating definition, so state the tier your market requires when you request a quotation.
How is a QSZ13 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.
