The speed record might just be Ricardo engineers having a bit of fun as they work on "achieving the world's cleanest diesel exhaust emissions standard (U.S. Tier II / Bin 2), as well as the roll-out in June of the Efficient-C hybrid diesel demonstrator vehicle, which boasts one of the world's most energy-efficient powertrains". The JCB444-LSR engines use the "Ricardo High Speed Diesel Race (HSDR) combustion system, which the company originally developed for competition applications. It also shares many technologies, which Ricardo is developing in order to make the vehicles of tomorrow more energy efficient and less polluting. In addition to diesel particulate filters for example, the JCB DIESELMAX includes technologies such as two-stage inter-cooled turbo-charging, high pressure fuel injection and a low compression ratio, low temperature combustion system. All of these technologies are being developed by Ricardo for application on the high performance, ultra-low emissions diesel vehicles of the future", the company said.
