Improvements in apparatus for supplying liquid fuel to the cylinders of internal combustion engines

... 142,188. Erickson, A. Jan. 29, 1919. Regulating.-Liquid fuel is vaporized and ignited in a cavity 12 in the head of the air-admission valve 10. The fuel is stored in the vessel 23 and flows into the hollow stem of a valve 20 through a needle valve 26 which is raised by the lever 38 acting through a wedge 39; the wedge is adjusted by a governor through a lever 41 and link 40. The fuel is warmed in the stem of the valve 20 and escapes therefrom when the lever 38 engages the collar 18. This oollar, in its downward movement, engages the collar 15 on the valve 10 and admits air to the cylinder. The air, during compression, enters the cavity 12 through holes 12a and raises the pressure therein high enough to ignite some of the fuel and thus expel the remainder. The invention is described in connexion with a two-stroke-cycle engine, but is equally applicable to four-stroke engines.

Patent DE3838944C2

Patent FR2259982B1

IC engine rapid fuel supply system - has insulated electrode extending into cavity and applying HV to cause electrical discharge

The fuel supply system for an engine includes a device defining a cavity (12) which communicates by way of an orifice (15) with a combustion chamber (10). A low-pressure fuel pump (17) supplies fuel to the cavity via a non-return valve (18) at a time when the pressure in the combustion chamber is low, e.g. towards the end of the suction stroke. Located in the cavity is an electrode (14) insulated by an insulator (13) from the wall of the cavity. With fuel in the cavity a spark discharge is caused to take place between the wall of the cavity and the electrode and the fuel and also air in the cavity expand through the orifice into the combustion chamber.

Methods and systems for reducing the formation of oxides of nitrogen during combustion of engines

The present disclosure is directed to various embodiments of systems and methods for reducing the production of harmful emissions in combustion engines. One method includes correlating combustion chamber temperature to acceleration of a power train component, such as a crankshaft. Once the relationship between acceleration/deceleration of the component and combustion temperature are known, an engine control module can be configured to adjust combustion parameters to reduce combustion temperature when acceleration data indicates peak combustion temperature is approaching a harmful level, such as a level conducive to the formation of undesirable oxides of nitrogen. Various embodiments of the methods and systems disclosed herein can employ injectors with integrated igniters providing efficient injection, ignition, and complete combustion of various types of fuels.

An improved apparatus for injecting and igniting fuel in an internal combustion engine includes a nozzle with a bore and a tip at a distal end. The bore includes a longitudinal axis and an annular valve seat. A needle reciprocates within the bore and in combination with the annular valve seat forms an injection valve where in a closed position the needle abuts the annular valve seat and in an open position the needle is spaced apart from the annular valve seat. A retainer axially protrudes from the tip of the nozzle along the longitudinal axis thereof whereby an annular mixing space extends between the retainer and the tip of the nozzle. There is an igniter secured to the nozzle that includes a positive-ignition source forming an ignition zone within a portion of the annular mixing space. Nozzle arrangements include those with both pilot hole and main holes in the nozzle extending between the plenum and outside the nozzle where the main hole longitudinal axis bypasses the retainer and a pilot fuel jet from the pilot hole(s) is retained and redirected such that an ignitable fuel-air mixture is formed within the annular mixing space.
