stroke engine
When up stroke cycle compression and inhale(
흡입
) ,ignition(
점화
)


Down stroke cycle explosion, exhaust(
배기
)


This feature is low component and weight per power is good!


But too many fuel consumption(

stroke engine

it is inhale, compression, explosion, exhaust


in regular sequence (
순서대로
)


This stroke feature low fuel consumption and rev count(rpm) is high


But too many component and weight per power is not good
