The boxer engine has horizontally-opposed pistons that contribute to lower vehicle center of gravity, improving handling and stability. Because the cylinders are on opposite sides of a central crankshaft, it provides better balance and the engine is shorter than inline or V configurations. This boxer design is lightweight, improves power-to-weight ratio, and has natural rotational balance. It has seen use in aircraft, motorcycles, and automobiles where its short, low profile is well-suited for compact layouts with low centers of gravity and less vibration than other engine types.

1. BOXER ENGINE

2. MEANING
 Horizontally-opposed pistons

3. Contribution to Vehicle Handling and
Stability:
 significantly lower
 This results in a low centre of gravity that has very significant advantages in
terms of the vehicle's handling and stability.

4.  Because half of the total number of cylinders is on one side and the other half
on the opposite side with a common crankshaft sandwiched in the middle.
 Very significant contribution to vehicle balance, stability and handling
 Boxer engine is comparatively short compared to a conventional 'in line' or 'V'
engine layout.
 Significant factor in vehicle handling, stability and also steering response.

5. Durability, Reliability and Lightweight:
 The Boxer engine is relatively lightweight.
 Improves the power to weight ratio.
 The natural rotational balance of the engine is very good.

7. Aviation use:
 Multi-cylinder boxer layouts have proved to be well suited as light
aircraft engines
 An important factor in aircraft use is the flat engine's absence of vibration,
which allows a lighter engine mount
Riedel starter for German WWII jet engines, with pull-start handle and cable

8. Motorcycle and Automotive use:
 A low center of gravity.
 Smoothness.
 Suitability for shaft drive
 Excellent cooling of the cylinders

9. Automobile layouts used with flat
engines:
 When mounted longitudinally in a vehicle, flat engines with up to six cylinders
are short, low, and wide. As a result, they have often been used in compact
drivetrains where the engine is mounted outside the wheelbase and drives the
nearer pair of wheels through them transmission without a drive shaft.

10. Flat engine designs
 Flat-twin engine
 Flat-four engine
 Flat-six engine
 Flat-eight engine
 Flat-ten engine
 Flat-twelve engine
 Flat-sixteen engine
 H-engine
 Controlled combustion engine

11. ADVANTAGES OF THE BOXER ENGINE:
 Better fuel economy and good fuel efficient.
 Low centre of gravity
 Less vibration
 Safety compare to inline and V engines.
