Technology Development Programme
Proof of Concept Work
The engine was the subject of a 4 year PhD at Queen Mary University of London as well as independent analysis at the University of Leeds. The work delivered a "proof of concept" engine, which produced positive power and specific energy competitive to lead acid batteries.
During Q4, 2011, Ricardo undertook a rigorous independent technology review, engine feasibility study, development of a detailed risk register, technology roadmap and a review of market potential. Ricardo concluded that
- there were no road-blocks or challenges to a commercial engine for which potential engineering solutions were not identified.
- existing, simple, mature technology and components could be used, thereby delivering an efficient and cost effective route to a proficient system and significantly reducing the cost of development and first commercial deployment.
Subsystems Development
In January 2012, the Company funded Ricardo to undertake:
- design, procurement and testing of the critical injector system;
- development and optimisation of other key engine sub-systems;
Following this work, potential showstoppers identified by Ricardo have been downgraded to performance challenges and the company is currently undertaking with Ricardo and its team of experts a programme that is focused on applications of the technology.
Combined Cold and Power - current / 2014
DEC is currently working with Ricardo, MIRA and a network of other experts to deliver the first liquid air engine, providing cooling and power.
The design and build of a single cylinder test engine was operational at the end of 2013.
1. Q1, 2014 will be the start of three months of engine testing, system integration and demonstration.
2. Approval of mobile systems for installation and demonstration on a mule vehicle with MIRA during Q2 2014.
3. Iteration of the mobile systems to a point where they can be used in a field demonstration programme in late 2014.
We are with E4Tech and Productiv (the Proving Factory) defining the route to production and design for manufacture for the combined cold and power engine to deliver low volume manufacture during H2, 2015.
Waste Heat Recovery - 2014
1. Design and Build of a 30-50kW Dearman Engine
2. Mechanical, thermal and control integration of Dearman Engine and IC Engine in a validated Environment (e.g. Mira, Lotus, Cosworth or Ricardo test cells)
3. Integration of Dearman/IC Engine powertrain into a vehicle
Future Applications Research
DEC is exploring with Ricardo and other partners in parallel with its main programmes routes to deliver improved performance and develop new technology applications, including as a zero-emission primary powertrain (tuktuks or quadricycles in the first instance). These applications when sufficiently mature will enter the prototype and vehicle demonstration process.
