We know, we know—CM missed the year's most important anniversary. A letter has flooded in, complaining that we failed to commemorate the 125th anniversary of the Otto engine cycle on 9 May 2001. It hardly seems possible that we forgot, especially as we received a spendidly helpful press release from the nice people at Deutz engines. Helpfully headed 'Intake, Compression, Combustion, Exhaust", the release describe the invention of the fourstroke spark-ignition engine, and goes on to tell us that "the Diesel engine also functions on this principle".
Well. actually, no: the Diesel cycle can be either two-or four-stroke, and relies on compression rather than spark ignition.
