    Honda used its proprietary computational fluid dynamics software to
optimize airflow within the compact engine, maximizing performance. The
engine's simple, high-performance combustion chamber keeps emission levels low
enough to meet the requirements of anticipated standards for compact jets.
    On the basis of electronic control technology originally developed for
automotive applications, Honda has created the first ultra-compact Full
Authority Digital Electronic Control (FADEC) system for this class of engine,
which provides superior engine operation and reliability without variable
mechanisms.
    Development of this engine began in 1999, and it has been submitted to
comprehensive testing, including required tests such as the 150-hour endurance
test. The engine has now logged more than 110 hours of flight-testing on other
manufacturers' aircraft, confirming its reliability.
