Overview

The Weichai M33 is a 19.6 L 6-cylinder Weichai diesel engine supplied in 109 factory ratings from 402 hp (300 kW) to 2072 hp (1545 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 M33 rating, including the 19.6 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: M33 Ratings

Each entry in this section is one rating of the Weichai M33. 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

M33 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 16M33C2100-18E221), 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 M33 specification, quantity and destination port for a verified quotation and lead time.

Frequently Asked Questions

What is the power range of the M33?

The 109 ratings listed on this page run from 402 hp (300 kW) to 2072 hp (1545 kW), at governed speeds between 1500 and 2000 rpm.

What displacement and cylinder count does the M33 use?

Every rating in this family shares the same 19.6 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 16M33C2100-18E211 and 16M33C2100-18E221?

16M33C2100-18E211 is rated 1545 kW (2072 hp) at 1800 rpm, while 16M33C2100-18E221 is rated 1545 kW (2072 hp) at 1800 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 M33 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.
