Definition
A reciprocating engine configuration in which two banks of cylinders are arranged at an angle to each other, sharing a common crankshaft, so that the cylinder banks form a V-shape when viewed from the front.
Plain English
An engine where the cylinders are arranged in two rows that lean away from each other, making a V-shape, with both rows turning the same central shaft.
Context Anchor
Seen when studying aircraft engine layouts and how reciprocating engines are arranged.
Derivation
Named directly for the shape: the two cylinder banks form the letter V when seen from the end of the engine.
Why Pilots Care
V-type engines provide a compact layout that supports higher power in a smaller and lighter package, which matters for aircraft performance and engine mounting.
Intuition Check
“V-type” does not mean a version or model type called V. It describes the physical shape made by the two angled rows of cylinders.
Example Sentence 1
The Rolls-Royce Merlin used in the P-51 Mustang is a classic V-type engine with twelve cylinders arranged in two banks of six.
Example Sentence 2
V-type engines allow the aircraft to carry more payload because the narrower design reduces overall engine weight.
