Not a comedy double-act, Atkinson and Miller were engineers, one British and one from the US who each invented methods for improving internal combustion engines. Both types were pretty much forgotten until recently when variable valve timing and electronics have made it possible to emulate the operating principle either style of engine in a conventional design. In fact it’s possible to have the same engine operate in conventional (Otto or Diesel) mode then switch to Atkinson or Miller operation to suit the conditions and load.
I’ve written a couple of pieces for Diesel Car, one on the history one on the modern interpretation of Atkinson and Miller’s designs. So if you ever wondered what Toyota are on about when they praise the simulated Atkinson engine used in the Prius, now’s your chance to find out.

Just got PDF files for two recent pieces I wrote for Diesel Car magazine’s EcoCar supplement.
VeryParticular deals with arguments about where particulate pollution comes from and whether or not hybrids and electric vehicles are as bad as has been suggested in some publications.
UsedEVs is a look at the rapidly developing market in secondhand Electric Vehicles.
Just finished a piece for Diesel Car about KERS and got plenty more ‘ghost blogging’ to do for a certain IT company. Hoping to get a regular column on Diesel Car / Eco Car, and yesterday at Yr Wyddfa met a guy who’s a lecturer in Environmental Science at UCL, and expert in hydrogen as a fuel. Should be useful…
Diesel fuel is a type of oil, and fracking is all about gas, right? If you want to know why and how fracking could make diesel cars cheaper and cleaner to run you’ll need to buy Diesel Car magazine (or download a PDF here).
