Weichai engine export prices are quoted per model and configuration, not from a fixed list. Six variables decide the number: power rating, emission standard, application configuration, order quantity, Incoterms and destination. Send the model designation and quantity and we return a firm quotation. All 211 models in this catalogue are covered.
As an indication, FOB prices across this catalogue run from USD 3,000 to USD 80,000 per unit, depending on model, power rating, emission tier and configuration. The number that applies to your order is the one quoted against your model designation – this range only tells you roughly where the catalogue sits.
What determines a Weichai engine price
- Power rating – the catalogue runs from 25 kW industrial units to 9,100 kW marine propulsion engines, and displacement scales with it (2 L to 87.5 L).
- Emission standard – China Stage VI, China Non-Road Stage III and IV, IMO Tier II, Euro VI and EU Stage IIIA / IIIB / V are all represented. Higher tiers carry after-treatment hardware and cost more.
- Application configuration – the same base engine is built differently for a truck, an excavator, a generator set or a marine propulsion package: cooling package, air intake, flywheel and housing, power take-off and control system all change.
- Order quantity – unit price moves with volume; Our minimum order quantity is one 40 ft high cube container (40HC) per order. Send us the model designation and we will confirm how many units load per container, with the loading plan and lead time stated in the quotation.
- Incoterms – EXW, FOB and CIF are all available, and the term alone changes the number substantially.
- Destination – freight, insurance and any destination-specific documentation are costed to the port and country you name.

Choosing the right power band
Most buyers already know the machine they are powering. If you only know the duty, this is how the bands map onto real equipment.
- 0-100 kW – Light trucks, pickups and vans, small forklifts, small generator sets and auxiliary marine sets. The usual entry point for fleet buyers.
- 100-250 kW – Medium and heavy-duty trucks, city and rear-engine buses, mid-size excavators, loaders and farm tractors. The largest band by model count.
- 250-400 kW – Heavy dump trucks, truck tractors, large wheel loaders, bulldozers, motor graders and mid-size drilling rigs.
- 400-800 kW – Mining excavators, rigid mining dump trucks, rail vehicles, large drilling rigs and medium-speed marine propulsion.
- 800-1500 kW – Large mining haulage, high-power generator sets and larger marine propulsion and auxiliary engines.
- 1500 kW and above – Very large marine propulsion engines, multi-megawatt generator sets and the top of the M-series marine range, up to 9,100 kW.
Coverage by application family
The 211 models split across five application families. Power span tells you how far each family reaches.

If you are unsure which tier your market requires, send the machine type and registration class and we will match a model to it.
What a quotation includes
- Engine supplied to the model designation you specify, genuine Weichai origin.
- Configuration as required by the application (cooling, intake, flywheel and PTO arrangement).
- Export packing suitable for sea freight.
- Standard export documentation set: commercial invoice, packing list and bill of lading.
- Lead time 30 to 90 days from order confirmation, confirmed per model.
- Payment terms: T/T: 30 % deposit, 70 % against copy of bill of lading.
Comparing two quotations
Export quotations are frequently compared across suppliers who are not quoting the same thing. Before you compare numbers, check that all four of these match: the exact model designation, the emission standard, the configuration (cooling, intake, flywheel, power take-off, control system) and the Incoterm. A price quoted EXW is not comparable with a price quoted CIF to your port, and a Stage III engine is not comparable with a Stage VI one even at the same rating.

What to send with your enquiry
Quotations are only as accurate as the specification behind them. Send these six items and you get a firm price and a firm date rather than a range.
- Engine model – the designation you need, or the machine it will be built into if you do not know it.
- Power – required rating in kW, and the duty cycle.
- Quantity – number of units, and whether this is a repeat order.
- Emission standard – the standard your market or registration class requires.
- Destination – country and port, plus the Incoterm you want quoted.
- Configuration – cooling package, power take-off, control system and any ancillaries.
Reach us at +86 138 6894 2030 or info@91engine.com. Both a factory site in Weifang, Shandong and an export office in Yiwu, Zhejiang support the shipment.
Frequently asked questions
- Do you publish a price list? No fixed list – engine pricing depends on configuration and volume, so every quotation is built per enquiry. As an indication, FOB prices across the catalogue run from USD 3,000 to USD 80,000 per unit.
- How fast can I get a number? Send model, quantity, destination port and Incoterm – we come back with a firm price and lead time.
- Is a lower emission tier cheaper? Usually yes, but only where your market accepts it. Confirm the required standard first.
