Mod (subculture)Mod, from the word modernist, is a subculture that began in London and spread throughout Great Britain and elsewhere, eventually influencing fashions and trends in other countries, and continues today on a smaller scale. Focused on music and fashion, the subculture has its roots in a small group of stylish London-based young men and women in the late 1950s who were termed modernists because they listened to modern jazz.
Two-stroke engineA two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time.
