How do Deltic engines work?
Built in this three-sided configuration, the Deltic diesel featured six banks of pistons working the three crankshafts. Imagine it as three V-shaped engines tied together at their crankshafts and each cylinder block merging with another cylinder half-way through the combustion chambers.
When was the Deltic introduced?
1961 and 1962

The mechanism of the Deltic Engine is shown in these animations. The three crankshafts are arranged in a triangular structure (the Greek letter “delta”, hence the name “Deltic”). On each crank are mounted two pistons, and each cylinder contains two pistons from adjacent crankshafts. The thermodynamic cycle of the Deltic engine is two-stroke.
