Advantages of 6-Stroke Engine | disadvantages of 6-Stroke Engine This page covers advantages and disadvantages of 6-Stroke Engine. It mentions 6-Stroke Engine advantages or benefits and 6-Stroke Engine disadvantages or drawbacks.

What is 6-Stroke Engine? Introduction: • The 4-stroke engine design is modified to design 6-stroke engine. • It improves efficiency and reduce emissions with less fuel consumption. • There are total 6 cycles with two power strokes. • The 6-stroke engines are categorized into single piston type and opposed piston type. • It delivers higher output power and torque. • There are two expansions (work/power stroke) in the six strokes.

The figure-1 depicts number of cycles in a six stroke engine. Refer comparison between 4 stroke engine versus 6 stroke engine >>.

Benefits or advantages of 6-Stroke Engine Following are the benefits or advantages of 6-Stroke Engine: ➨Power output is higher. It is increased by 35% compare to 4stroke engine. ➨Emission is less and hence air pollution is lower by up to 65%. ➨Thermal efficiency is higher. ➨Fuel consumption is less. It is reduced by 40% compare to 4stroke engine. ➨Lower engine temperature and noise level. ➨Due to more air intake, the cooling system is improved. Hence external cooling is not required. ➨The output torque is increased by 35% compare to 4-stroke engine.

Drawbacks or disadvantages of 6-Stroke Engine Following are the disadvantages of 6-Stroke Engine: ➨It requires modifications to existing 4-stroke engine. ➨There are chances of entry of water in the fuel. ➨Brake power and indicated power per cycle per cylinder is comparatively lesser. ➨Engine size increases due to additional components. ➨The manufacturing cost of 6-stroke engine is higher.
