Fast-NGC at the Royal Institution

Fast-NGC at the Royal Institution

Dr. Felix Leach presenting at the Royal Institution

On 25th April 2017, Dr Felix Leach presented the group's most recent project 'Fast-NGC, advanced fuel flow measurement' at the Preparing for the Grand Challenge event organised by the Advanced Propulsion Centre (APC) at the Royal Institution in London.

Felix presented preliminary work on Next Generation Coriolis Meters, measuring fuel flow in an individual diesel injector at pressures of up to 1000 bar.  This project was an £80k, 3-month (APC) funded feasibility study.

Our preliminary results attracted considerable attention at the event and we are hopeful that future collaborations and progress with this exciting idea will result. Watch this space!

Oxford's latest work on PN measurements has now been published in the International Journal of Engine Research. The work, which can be accessed here, focuses on PN emissions from a very highly boosted GDI engine (the ULTRABOOST engine at the University of Bath).

Highly boosted GDI engines offer significant potential fuel economy benefits. Our study characterised particulate emissions from an extreme example of this type of engine using a Cambustion DMS 500 particle analyser. The very small particles sizes recorded have important implications for future aftertreatment design and the potential impacts of pollution from these engines.

A subset of this work was presented at the 2017 Cambridge Particle Meeting by Oxford researcher, and lead author on this work, Dr. Felix Leach. Congratulations to Felix and his co-authors and collaborators.

Not dead yet!

On the 12th August this year, the Economist magazine led with a cover story entitled titled “Roadkill: The death of the internal combustion engine”. Oxford Combustion and Engine’s Group Researcher Dr Felix Leach felt that this deliberately provocative article shouldn’t go unanswered and penned a reply.  Today, the Economist published an edited version of Dr Leach’s letter, which has been co-signed by 19 other leading UK academics in the field including the Group’s own Dr Martin Davy and Professor Richard Stone.  The Economist magazine boasts an average weekly circulation of 1.5 million and 10.5 million online readers per month. Accordingly, we believe that Dr Leach’s letter will have a high impact and that it is an important contribution to the debate on the future of the combustion engine. Noting that the magazine has edited Dr Leach’s original letter for publication, we present the full submitted text and the signatory list below.

Dear Editor,

You lead with the Death of the Internal Combustion Engine (ICE). We could not disagree more. Battery Electric Vehicles (BEV) are part of the future, clearly, however credible studies (e.g. IEA World Energy Outlook) suggest that 90% of ground transportation energy will continue to be from hydrocarbon-based fuels (both renewable and traditional sources) in 2040.  In addition, current electrical generation capacities do not come close to meeting the needs of an all-electric fleet and battery production is not emission free.  Road freight, agriculture/construction vehicles, and long-distance vehicles (e.g. coaches) will continue to be powered by ICEs, there is little other choice. When you refer to a ban on “new cars completely reliant on ICEs”, many such vehicles will still contain an ICE as a hybrid. The ICE of today is a modern machine with a huge number of recent technological innovations both to increase its efficiency and decrease its emissions. Further advances in ICE technology will enable near pollutant-free mobility and future fuels offer sustainable decarbonisation strategies.

The demonisation of the ICE makes good politics, but poor engineering; in order to reduce both CO2 and local pollutant (e.g. NOx and soot) emissions, there should be significant attention focused not only on ICEs of the future, but on electrical power generation, domestic heating, rail electrification, and well-to-wheel emissions.  If we cease to invest in the ICE now, there is a significant danger of opportunity loss if BEV technology does not meet expectations on time.

The Internal Combustion Engine will continue to be part of the solution for the foreseeable future.
