As we are currently in the technology demonstration phase, we aim to keep you updated with the latest news and events on the project as and when they happen.
We are in an exciting phase where we are heading towards Technology Readiness Level 4 and solid evidence to support our claims about reduced specific fuel consumption and emissions.
If you have any questions, please don’t hesitiate to get in touch and we will respond as soon as we are able.
After the very successful simulated competition in which Olly Cook for Chipping Sodbury School took third place on the Podium, an uncertain start to the live season took place on the 13th September when the first races were ran at Castle Combe. Covaxe-sponsored Olly came 8th out of 24 in Pod 6.
The next race is planned for Goodwood but there is uncertainty in the current Covid climate.
As a result of Covid-19 the Greenpower Challenge races have been cancelled until the autumn.
However the challenge remains unthwarted and has been supplanted by virtual races at simulated real Formula 1 circuits which are now available on Youtube.
The race is run in exacting simulations of real cars and the Covaxe-sponsored cars are driven by Olly of Chipping Sodbury School, who excelled in the first two races. He currently leads the championship having come third in the races on the Brands Hatch and Oulton Park circuits, despite failing to start in the third race owing to an electronics glitch.
Covaxe continues to support its green credentials and its objective of producing a clean, efficient compression-ignition engine.
As we move towards the first testing of our Demonstrator Engine, the results of our collaborative study with Southampton University have just been published. The paper, entitled ‘A Numerical Study of a Compression Ignition Engine Operating with Constant Volume Combustion Phase: Effects of Constant Volume Phase on Combustion Performance and Emissions’, gives confidence that we are well on our way to achieving our objectives.
The study was carried out by PhD student Callum Ramsey under the supervision of Dr Kahanda Koralage Dinesh. It used computer fluid dynamics (CFD) modelling of the engine and examined the effects of varying the constant-volume duration, the fuel injection start time, and the effects of exhaust gas re-circulation.(EGR).
It showed that significant reductions in nitrogen oxides as well as virtual elimination of soot emissions could be achieved whilst still attaining the considerable improvement in specific fuel consumption offered by constant volume combustion.
Testing of the demonstrator engine is scheduled to start later in the summer with evaluation of the sliding and rotating bearing losses. This will be followed in the autumn with load tests on a dynamometer test cell in the premises of our sister company Covaxe GmbH in Aachen, Germany.
Further studies at Southampton of a more detailed multi-cylinder model of the engine is planned for 2021 and direct validation will follow from the testing.
At the final race of the year at Rockingham , POD-6 performed immaculately and successfully completed the three races of the day. When the final results were calculated, POD-6 ended up in twenty-seventh place out of over two hundred cars competing during the year. These included cars from as far afield as the USA and Brazil!
POD-6, the re-vamped Greenpower car from Chipping Sodbury School, has had a very successful year. The reliability problems have been overcome and the car has climbed its way towards the top of the table.
At the penultimate heat at Castle Combe on 15th September the Covaxe-sponsored POD-6, which started the year in 93rd position, ended in ninth place out of seventy-two cars racing that day..
Chipping Sodbury’s Rotary Racer and Chain Reaction finished 3rd and 17th respectively.
All hangs now on the final race at Rockingham on 5th October!
We are delighted to announce that covaxe® is supporting the development of a new electric car at Chipping Sodbury School for the 2018 Greenpower season.
A new car was trialled in 2017 and the 2018 season is just starting with the car, which has improved aerodynamics and better motor cooling.
We are now covaxe® – Constant Volume Axial Engines. covaxe® is still developing the same innovative engine, same savings in fuel consumption and CO2 emissions, same reductions in particulate emissions, same exciting research and development project.
But a new name and a new brand for a cleaner, greener image.
In April we joined the Technology Developer Accelerator Programme. The UK Advanced Propulsion Centre have awarded us a place on the “Technology Developer Accelerator Programme”, a programme sponsored by the UK Government’s Department for Business, Energy and Industrial Strategy with the aim of accelerating the development of cutting-edge technologies to reduce carbon emissions in the automotive industry.
