The facts on the card
The card carries these facts from its Wikipedia article.
- IOE engines were widely used in early motorcycles, initially with the inlet valve being operated by engine suction instead of a cam-activated valvetrain.
- When the suction-operated inlet valves reached their limits as engine speeds increased, the manufacturers modified the designs by adding a mechanical valvetrain for the inlet valve.
- A few automobile manufacturers, including Willys, Rolls-Royce and Humber also made IOE engines for both cars and military vehicles.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The IOE engine article was read about 12,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 67 and blocks with 45: each hit it takes is cut by 18 %.
