Hiro Type 14
From Wikipedia, the free encyclopedia
The Hiro Type 14 engine, (full designation Hiro Type 14 500 hp water-cooled W-12), was a water-cooled twelve-cylinder W engine built by the Hiro Naval Arsenal (Hiro Kaigun Ko-sho) for the Imperial Japanese Navy. The Hiro Type 14 engine design was based on the Napier Lion. Like the parent engine, and the Lorraine 12 Eb, it had three banks of four cylinders each, with the center bank upright, and the other two banks angled outward 60 degrees. In some cases the W engine is referred to as the broad arrow configuration, due to its shape resembling the British government broad arrow property mark.[1] The first aircraft to be powered by a Type 14 engine was the Hiro H2H flying boat.[2]
