Flat-twin engine:-
A flat-twin is a two cylinder internal combustion engine with the cylinders arranged on opposite sides of the crankshaft.
BMW Motorrad manufactures a number of flat-twin engine motorcycles,as do Ural and Dnepr. The geometry gives good primary balance, but there is an unbalanced moment on the crankshaft caused by the pistons being offset from each other.
Flat-twin engines were used in several of Henry Ford's early cars, including the Ford 1903-04 Model A, Model C, and Model F.Flat-twins have been used to power light aircraft, although most piston-engined aircraft have used more cylinders for more power. Notable flat-twin aircraft engines include the Aeronca E-107 and E-113, the Praga B2, and the Bristol Cherub.
A disadvantage of this layout is that it exposes the cylinders and valve covers to the danger of collision damage.
