There's another notable Atkinson engine in some petrol Honda Civic Euro FK2 (2006-2011), can't remember engine code, but on that one i-VTEC is able to let inlet valves up during the beginning of the up stroke compression phase, turning the 140hp 1.8l engine into down to a 1.6l one. Turbo-less downsizing with all the benefits of a full-size (aluminium, so lightweight) block. Interesting tech. I owned one, the resulting fuel economy puts diesel engine to shame.
