Dolphin N2 acquired by FPT Industrial.

  • by

FPT Industrial, brand of CNH Industrial dedicated to the design, production and sale of powertrains for on and off-road vehicles, marine and power generation applications, has purchased Ricardo plc spin-out Dolphin N2 and its revolutionary recuperated split-cycle engine.
The engine is extremely efficient, making it more comparable to a fuel cell than to a traditional engine. It also produces near-zero emissions of harmful nitrogen oxide (NOx) – a world first.
To enable the sale, the technology was developed and proven in an Innovate UK-funded consortium project called StepCO2, with Dolphin N2, Ricardo plc, Brighton University, Sheffield University and Hiflux Ltd as partners.
The new technology will be suitable for heavy duty vehicles including long-haul trucks, stationary power, off-highway equipment and self-powered multi-mode railway traction, applications that are, at present, unsuitable for battery-electric propulsion. Unlike with cars, a long-haul truck would need to use a sizeable proportion of its cargo space to house the number of batteries needed to propel the truck if it were electrified.
The Recuperated Split Cycle process combines the recovery of otherwise wasted exhaust heat with a complete re-design of the engine’s core four-stroke principle, splitting the cold and hot parts of the cycle. UK-based company Hiflux Ltd have developed a unique compact high temperature heat exchanger – one of the enabling components of this engine.
The invention is seen as one of the most significant advances in engine design in years. Simon Brewster, CEO of Dolphin N2, said: “FPT Industrial is the ideal partner to take this revolutionary technology to market. We knew the technology had world-leading efficiency, but through our work on the StepCO2 programme, we have also been able to demonstrate incredibly low levels of NOx emissions.
Tanzi Besant, Managing Director of Hiflux said: “Hiflux is pleased to be involved in this exciting engine development – the commercial importance of which has clearly been demonstrated by the acquisition of Dolphin N2 by FPT Industrial. Hiflux has a unique heat exchanger technology which is well suited for the demanding operating conditions such an engine presents along with highly automated manufacturing methods necessary for volume applications.”
