Who builds Ricardo-type engines

Ricardo-type diesel engines are not made by a single company. They are produced by a number of licensed and regional manufacturers, and the same model may be built by different producers depending on the engine series and target market.

Important notes on manufacturing

  • Ricardo-type diesel engines are not produced by a single company; they are manufactured by different licensed or regional manufacturers.
  • The set of active producers changes over time — this page does not claim these are the only factories.
  • Which factory builds a given engine may depend on the engine series, configuration and target market.
  • Component quality, machining tolerances and quality control can differ between producers, which affects real-world performance and longevity.

The producers referenced above are examples of publicly documented manufacturers of Ricardo-based engine product lines. This is not presented as an exhaustive or exclusive list, and specific licensing arrangements and product availability can change over time. Always verify the actual manufacturer, specification and warranty of any engine with the supplier before purchase.
