CESAR Overview
- For realistic pollution control
- Combustion engine in direct drive for open areas
- Auxiliary power in town
- Energy storage is the key
The CESAR Principle
Presently, transportation of any type is almost wholly dependent upon internal combustion engines burning, usually a liquid, hydrocarbon fuel, which result in harmful emissions. While hydrocarbon fuels continue to be used, we aim to reduce the extent of pollution. Clean Power aims to do this by increasing the efficiency of intrinsic energy usage through storing the currently dissipated heat and recovering this cleanly, providing power where emissions is not allowed - the CESAR principle.
The CESAR system broadly consists of a sophisticated 'box shaped' heat exchanging device that fits into the vehicle exhaust pipe and is supplied by pumped water from a feeder Tank. Heat energy can be stored in many ways in many substances, but none better that water, the liquid that, with its high latent heat and general thermal properties make it so crucial to life on earth. Saturated water can contain large amounts of energy which can easily and cleanly be released as steam vapour to produce mechanical power. The steam is super-heated to approximately 350 degrees Celsius with a pressure of approximately 40 Bar. The generated steam is fed through electronic and mechanical control and regulating devices to power a steam engine. The steam engine exhausts into a condenser which returns condensed water through an oil separator back to the feeder tank thus completing a 'Closed Loop' system. A small supplementary diesel burner is fitted inside the heat exchanger as a back-up should steam power still be required when the vehicle's engine is shut down.
The Design Challenge
Control of such machines to quickly adapt operating speed and power output to traction requirements will present a major fundamental design challenge even with the modern availability of electronic and computer management of engine operation. The control system will need to optimise the power balance between the combustion and steam engines, the combustion engine providing enough exhaust heat to maintain the accumulator pressure as the vapour engine maintains the total power required by the traction demand.
