Why are opposed-piston engines more efficient?
Theory suggests that an opposed-piston engine has an efficiency advantage because, since there are no cylinder heads, less heat is lost to the cooling system. Think about a conventional combustion chamber in which the surfaces consist of a piston crown, a short cylindrical circumference, and a cylinder head.
What was an advantage of the flat horizontally opposed engine?
The Inline is more efficient being lighter and simpler, but is not particular rigid which limits its size. The horizontally opposed Flat engine has a performance advantage over the others with good balance and power, but are very wide and use up valuable space needed for other components and so are not widely used.
What is an advantage of an opposed engine?
Compared to contemporary two-stroke engines, which used a conventional design of one piston per cylinder, the advantages of the opposed-piston engine have been recognized as: Eliminating the cylinder head and valvetrain, which reduces weight, complexity, cost, heat loss, and friction loss of the engine.
What are the advantages of boxer engines?
The advantage of a boxer engine is that the engine counter balances itself. The pistons that are across from each other move toward the crank and away from the crank at the same time. This gives smoother operation and a crank shaft that is lighter because no counter balance weights are required.

What is the advantage of opposed engine?
Why opposed or O type engines are ideal for small aircraft?
Opposed or O-Type Engines The pistons of both cylinder banks are connected to the single crankshaft. The opposed-type engine has a low weight-to-horsepower ratio, and its narrow silhouette makes it ideal for horizontal installation on the aircraft wings (twin engine applications).
What are the disadvantages of an opposed engine?
Disadvantages:- Requires either two crankshafts, or a rocker arrangement to drive a single crank mounted below or above the cylinders. It is also difficult to arrange a valve layout for four stroke configuration within the cylinders, so most have been two-stroke engines which are not very fuel-efficient.
