The information upon which these pages are based is extracted from manufacturers' and
contemporary publications pertaining to the engines. Many of these engines were built for specific applications and therefore specifications vary,
as well as builds developed during production runs. Power ratings are the maximum a particular engine can produce,
although many units are de-rated for certain duties. Information here can only be taken
as an approximate guide.
