Diesel \Diesel\, Diesel engine \Die"sel en`gine\ or Diesel motor
\Die"sel mo`tor\ (d[=e]"zel). [After Dr. Rudolf Diesel, of
   Munich, the inventor.]
   A type of internal-combustion engine in which the air drawn
   in by the suction stroke is so highly compressed that the
   heat generated ignites the fuel (usually a heavy oil), the
   fuel being automatically sprayed into the cylinder under
   pressure. The Diesel engine has a very high thermal
   efficiency.
