Question

can you please give me:

- a disadvantage of a vee engine

- a advantage AND a disadvantage of a horizontally opposed engine

- a disadvantage of a rotary engine

Answer 1

Disadvantage usually Weight and size, take up a lot of room, almost always water cooled.

Horizontally opposed- Advantage, cheap to buy, light, usually air cooled. Disadvantage- usually low horsepower- don't start well in cold climates.

Disadvantage of rotary engines- the biggest one, not many people can work on/rebuild them. Not much low end torque, usually high polluter motor.
