There is a need for reduced fuel usage with cost-effective technology to improve the efficiency of urban heavy duty vehicles like buses and delivery trucks. Air-conditioning can double the fuel consumption of a bus in the worst conditions, so addressing this secondary use of power can bring significant environmental and cost benefits.

In a future where more urban vehicles adopt electric drive, providing power for cooling and other services can also have a serious impact on the vehicle’s range. In hot climates the combination of cooling and battery temperature control can make electrification unfeasible.

Dearman is developing a zero-emission solution, using a Dearman engine in a combined auxiliary power and cooling unit that will offer lower life-cost, reduced fuel usage and reduced emissions, for only a small increase in capital cost.

The Dearman auxiliary power system would be a cost effective enhancement to a vehicle’s systems, utilising the unique properties of an engine powered by liquid nitrogen to provide efficient cooling and also sufficient power for the vehicle’s electrified braking, steering assistance, electric doors, lighting etc.

Economic modelling indicates that bus operators could achieve payback on a Dearman system in as little as two years. Operators of refrigerated vehicles could achieve payback within a year.

The Dearman auxiliary power system would be a cost effective enhancement to a vehicle’s systems, utilising the unique properties of an engine powered by liquid nitrogen to provide efficient cooling and also sufficient power for the vehicle’s electrified braking, steering assistance, electric doors, lighting etc.

This approach would lessen the requirement for a vehicle to run its engine while stationary, and either reduce fuel usage or increase battery range. It could even have a positive impact upon long term vehicle design, by reducing the maximum load on the engine or the battery, enabling both to potentially be downsized and made lighter.
