Engine Specifications

Five cylinder engines mostly. Not responsible for accuracy of content.

Currently sorted alphanumerabetically, I may change to chronological. Yup, got bored and sorted by date of introduction.

Column codes:
EC=engine code; B=bore mm; S=stroke mm; CR=compression ratio (:1); V=number of valves;
T=turbo Y/N; C=catalyst Y/N; O=oxygen sensor Y/N;

Valve timing, in degrees:
IO=inlet open; IC=inlet close; EO=exhaust open; EC=exhaust close
AT=after top dead center; AB=after bottom dc; BB=before bottom dc; BT=before top dc
