Overview
The Weichai WP10 is a 9.726 L 6-cylinder Weichai diesel engine supplied in 34 factory ratings from 180 hp (134 kW) to 389 hp (290 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 WP10 rating, including the 9.726 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: WP10 Ratings
Each entry in this section is one rating of the Weichai WP10. 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
WP10 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 WP10C395-22E220), 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 WP10 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What is the power range of the WP10?
The 34 ratings listed on this page run from 180 hp (134 kW) to 389 hp (290 kW), at governed speeds between 1500 and 2200 rpm.
What displacement and cylinder count does the WP10 use?
Every rating in this family shares the same 9.726 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 WP10C395-22 and WP10C395-22E220?
WP10C395-22 is rated 290 kW (389 hp) at 2200 rpm, while WP10C395-22E220 is rated 290 kW (389 hp) at 2200 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 WP10 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.
