REVOLUTION: New engine could help fleets

A revolutionary new zero-emission engine could save truck operators thousands of pounds in fuel costs, it has been claimed.

The UK-developed Dearman engine, which runs on liquid nitrogen, will undertake full on-vehicle testing this summer, and provides the power for refrigerated trailer applications.

It could be in production within two years and, with a network of industrial gas plants across the UK already producing liquid nitrogen, there is no infrastructure barrier.

The cutting-edge engine completed its ‘shakedown’ testing milestone at the end of 2013 at Imperial College, London, and is moving into a three-month programme of tests and performance mapping.

It remains on track for integration and installation on a vehicle by the Motor Industry Research Association (MIRA) in the first half of this year.

Chris Reeves, Commercial Manager for Future Transport Technologies and Intelligent Mobility at MIRA, said: “MIRA is proud to lead a project delivering the world’s first demonstration of a liquid air engine in a commercial vehicle.

“Liquid air is an exciting new energy vector and has the potential to make a major contribution to the low carbon challenge facing the transport sector.”

The adoption of liquid air technologies in heavy-duty vehicles could reduce the UK’s diesel consumption by 1.3billion litres by 2025, with carbon emission cuts of a million tonnes.

A major new report due in March, Liquid air on the commercial highway, identifies the roll-out of liquid air vehicles could be fuelled entirely from existing spare industrial gas plant production capacity until at least 2019.

The engine is the brainchild of British garage-inventor Peter Dearman, and developed in partnership with top UK engineering consultancy Ricardo and a number of leading UK universities.

    Will the engine be produced as a bolt-on accessory for existing lorries? If they’re trying to promote GREEN then that could help and make it affordable for companies to convert existing fleets…

    Will it have the usual price tag of 10 times the cost of a usual vehicle to prevent anyone from denying government their fuel tax?
