Detailed modeling of this approach undertaken through the Technology Strategy Board-funded “CoolR” project has suggested that efficiencies of more than 60% are possible, compared to around 40% for current diesel engines. The Dearman Engine operates by the vaporization and expansion of cryogenic fluids.

High-pressure air supplied from a compressed air storage tank is jetted into the power cylinder through a high-pressure air jet system near TDC. However, the control of combustion phasing is one of the crucial issues in determining whether the diesel PCCI engine could be commercialized or not. —Meng et al. 5b01842.
