Overview
The Weichai X6170Z is a 27.24 L 6-cylinder Weichai diesel engine supplied in 40 factory ratings from 295 hp (220 kW) to 868 hp (647 kW). Every rating listed on this page is a complete engine for marine 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 X6170Z rating, including the 27.24 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: X6170Z Ratings
Each entry in this section is one rating of the Weichai X6170Z. 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.

Applications
X6170Z engines in this family are normally specified for marine work.
Marine: ratings are quoted against the propulsion or auxiliary duty required, with the gearbox ratio and the duty classification taken into account.
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 X6170ZC8805), 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 X6170Z specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What is the power range of the X6170Z?
The 40 ratings listed on this page run from 295 hp (220 kW) to 868 hp (647 kW), at governed speeds between 1000 and 1500 rpm.
What displacement and cylinder count does the X6170Z use?
Every rating in this family shares the same 27.24 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 X6170ZC880-5 and X6170ZC8805?
X6170ZC880-5 is rated 647 kW (868 hp) at 1500 rpm, while X6170ZC8805 is rated 647 kW (868 hp) at 1500 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.
How is a X6170Z 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.
