Abstract
An engine comprises a combustion chamber and interior walls which define a fuel induction passage having a fuel outlet port communicating with the combustion chamber. A first fuel delivery system introduces fuel from a fuel source into the combustion chamber. A second fuel delivery system includes a nozzle which extends into the fuel induction passage adjacent to the fuel outlet port and is selectively operable by means of an associated valve mechanism for introducing fuel from the source directly into the combustion chamber through the nozzle in addition to the fuel which is introduced into the combustion chamber by the first fuel delivery system.
Claims6
An engine comprising a combustion chamber, wall means for defining a fuel induction passage having a fuel outlet port communicating with said combustion chamber, fuel pumping means adapted for connection to a fuel source, first fuel delivery means communicating with said fuel pumping means for delivery of fuel thereto and with said fuel induction passage for introducing fuel therefrom into said combustion chamber, second fuel delivery means communicating with said fuel pumping means for delivery of fuel thereinto independently of said first fuel delivery means and including nozzle means extending into said fuel induction passage adjacent to said fuel outlet port for emitting fuel directly into said combustion chamber through said fuel outlet port, said second fuel delivery means being operative for introducing fuel directly into said combustion chamber through said nozzle means in addition to the fuel introduced by said first fuel delivery means, and control means connected to said second fuel delivery means for selectively operating said second fuel delivery means to introduce fuel into said combustion chamber through said nozzle.
