The history of the racing engine—and perhaps to a lesser extent the road going engine as well—has been driven by advancements in induction and valve train technology.
Once the 4-stroke Otto cycle form of internal combustion engine became the standard, some of the greatest leaps in performance and efficiency came through improvements in the engines ability to “breathe.” Today, despite claims of the internal combustion engine’s imminent demise, a new technological development is poised to revolutionize and improve the gas-burning engine—EAV, or Electronically Activated Valves.
