Abstract
Sparkplug means for an internal combustion engine are provided with conduits to introduce pre-combustion gases directly to a mixing area adjacent the sparking electrodes. This may be by connecting the conduits into the plug directly or by connecting them into an adapter to be interposed between the engine and the sparkplug, and providing a pre-combustion chamber therebetween. Preferably there is a mixing area upstream of the electrodes. An electrolyzer can be built into the arrangement to generate the pre-combustion gases immediately adjacent the sparkplug.
Claims15
In an arrangement for supplying two gases to an internal combustion engine that may explode when united, without combining them at a distance from the point of combustion, thereby to reduce the hazard of explosive pre-combining of the gases:
- spark means comprising a body shell having means to mount it on the cylinder of the engine, means associated with the shell providing sealed electrodes to give a spark for ignition;
- means in said body shell to supply a first pre-combustion gas therein, means in said body shell to supply a second pre-combustion gas therein, and means in said body shell to combine said gases and dispose said combined gases adjacent the electrodes, and means to prevent backflow of gases from the shell.
In a combination for use with an internal combustion engine:
- shell means, means on the shell means to secure it into such an engine at a point for providing normal ignition for the engine;
- the shell having first electrode means;
- second electrode means;
- insulation connecting the second electrode means into the shell but electrically insulated therefrom, the second electrode means extending adjacent the first electrode means adjacent the ignition point, the shell having an outlet for discharge into the engine cylinder, means to supply first and second pre-combustion gases into the shell;
- means to combine the gases in the shell;
- means to dispose the pre-combustion gases at the ignition point, and means to prevent backflow of gases into the conduit means to preserve engine compression when the pre-combustion gases are ignited.
In combination for use with an internal combustion engine:
- a hollow shell adapted to contain an electrolyte, and having means to secure it into a sparkplug opening of the engine, the shell providing a first electrode;
- a spark electrode, means supporting the spark electrode within the shell but insulated therefrom, the spark electrode extending adjacent the first electrode at a location where sparking between them may occur to ignite engine fuel;
- an additional electrode within the shell, the shell being adapted to receive electrolyte therein in contact with the first and additional electrodes, insulation separating the additional electrode from the first electrode and the spark electrode, means to introduce electric voltage to the first and additional electrodes, the additional electrode being cooperable with the first electrode to generate pre-combustion gases from the electrolyte in the shell;
- passage means from the shell to the portion of the shell where ignition sparking occurs, the passage means being adapted to conduct pre-ignition gases to the said portion of the shell.
