Question: what is the difference between 2 stroke engine and 4 stroke engine?
Answer: Four-stroke engines are heavier; they weigh upwards of 50% more than a comparable 2stroke engine. Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM. ... Two-stroke engines require pre-mixing of oil and fuel, while the 4-strokes do not.
