   Designating an internal-combustion engine of a type
   resembling the Diesel engine in using as fuel heavy oil which
   is injected in a spray just before the end of the compression
   stroke and is fired without electrical ignition. The fuel is
   sprayed into an iron box (called a hot bulb or hot pot)
