Marine engine enquiries and model confirmation

This category currently contains the Ricardo two-cylinder diesel engine listing. Use it as a starting point for a model-specific enquiry. Its presence in this category does not establish marine approval, classification-society acceptance or suitability for a particular vessel. Confirm the supplied manufacturer, model and applicable documents for your project.

Describe the vessel and engine duty

Tell Junwei Machinery whether the proposed engine is for propulsion, auxiliary equipment or another onboard application. Share the vessel type, intended operating area, equipment to be driven, required shaft power and speed, operating hours and available installation space.

Provide the proposed coupling or gearbox arrangement, shaft or flange drawing, rotation direction and mounting details. Include the cooling-water arrangement, ventilation and exhaust requirements, starting electrical supply and any controls or instruments requested for the installation. Photographs and drawings help identify the configuration that needs to be assessed.

Request documents for the exact supplied model

Ask for a current data sheet, nameplate details, installation drawing, operating manual and a written list of supplied components. Specify any flag-state, classification-society, emissions or other project requirements so the relevant model-specific evidence can be reviewed before purchase.

For general engine selection, you can also review the two-cylinder engine category. Send a marine engine enquiry with your destination, quantity and requested delivery date, and confirm technical suitability, documentation, lead time and warranty terms in the quotation.
