Before discussing on this topic first you should know about stroke. Working of 2 stroke engine! Position doesnt matter :- 2 stroke engine can work in any position as lubrication is done through the means of fuel (as the fuel passes by through whole cylinder crankcase). 4-stroke motors also have a crankcase and an oil distribution system which keeps the oil separate from the gas as it lubricates the engine components. For high torque considerations, 4-cycle may awaited Careers in Music and Broadcasting Industry indeed be the way to go, but for the most part we recommend sticking with the tried and true 2-cycle models the pros do! These engines are comparatively heavier than 2 strokes due to heavy flywheel and valve mechanism.
Advantage, higher vibration, fuel, economy, less efficient, advantage, emissions. These are mostly used in ships, scooters etc. More fuel efficiency :- 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes. Check out our review of the. Earlier in the Engines section we saw how 4 stroke 2 stroke engines work!
Two Stroke Engines VS. Four Stroke Engines
The basic and main difference between two stroke and four stroke engine is that the crankshaft complete one revolution in one power stroke in 2 stroke engine and complete two revolution in one power stroke in four stroke engine. We all know that more the engine runs, quicker it wears out. It requires heavy flywheel because it generates unbalance force due to two revolutions for one power stroke. So the 2 stroke engine give high power compare to 4 stroke engine but the 4 stroke engine is more fuel efficient. It takes two full revolutions of the crankshaft to deliver these four strokes. Addition of oil is required.
