The two JCB444-LSR engines which power the JCB DIESELMAX use the advanced Ricardo High Speed Diesel Race (HSDR) combustion system, which the company originally developed for competition applications. It also shares many energy-efficiency and emissions-reduction technologies Ricardo is developing for standard transportation applications.

JCB is a construction and agricultural equipment manufacturing company—the JCB444 diesel engine normally powers mid-range construction equipment such as backhoe loaders and telescopic handlers.

In addition to diesel particulate filters, 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.

Ricardo earlier announced it is working with an automaker on a SULEV Tier 2 Bin 2 diesel for passenger cars. (Earlier post.)

Having already taken the FIA international land speed record for a diesel vehicle, the JCB DIESELMAX team will continue to run at Bonneville over the coming days with a view to further increasing the record.
