diesel motor - Collaborative International Dictionary of English v.0.48 :

  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.
     [Webster 1913 Suppl.]
