Why is the four-stroke motor more desirable than the two-stroke mower in terms of environmental impact?

Two stroke motors have oil mixed with the petrol which does not allow complete combustion. The nature of the 2 stroke cycle creates greater power but less efficient use of fuel. Orbital Engine Company is a company that develops and manufactures high efficiency 2 stroke motors.

This is a topic that can come up with lots of answers.Enviromentally you dont have to dispose of the old black engine oil from a 2stroke like you do with a 4 stroke
