Information AboutH Engine |
For the Saab "H" engine (a Straight-4 ) see Saab H Engine An H engine (or H-block) is an Engine Configuration in which the Cylinder s are aligned so that if viewed from the front appear to be in a horizontal letter H . An H engine can be viewed as two Flat Engine s, one atop the other. The "two engines" each have their own Crankshaft , which are then geared together at one end for power-take-off. This leads to a worse Power-to-weight Ratio than simpler configurations with only one shaft. The only obvious advantage of the H configuration is to allow the building of reasonably short engines with more than 12 cylinders, their compact size being useful as Aircraft Engine s where their small size allows for better Aerodynamics - see Lycoming . The H configuration is therefore very uncommon. Known examples are:
Subaru produces water-cooled Flat-4 and Flat-6 "Horizontal" engines that are marketed as H-4 and H-6, despite the fact that their configuration has nothing to do with a real H engine. |
