Abstract

Abstract An ignition system, particularly for an internal combustion engine having a piston slidably disposed within a cylinder and coacting with the housing to define a combustion chamber therebetween. An ignition device is mounted on the housing for igniting a fuel-air mixture within the combustion chamber. The ignition device includes a high intensity light source within a sealed compartment, which compartment is isolated from the combustion chamber by an intermediate lens. The light source is preferably partially surrounded by a reflector so that, upon energization of the light, the radiant energy is transmitted through the lens which causes the light energy to be concentrated at a point located within the combustion chamber for causing ignition of the fuel-air mixture.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 143 words
In an internal combustion engine having housing means defining a cylinder therein and a piston slidably disposed within said cylinder, said piston and said cylinder cooperating to define a combustion chamber, and an ignition device coacting with said combustion chamber for igniting a fuel-air mixture therein, the improvement wherein said ignition device comprises: a support housing fixed to said housing means and defining a compartment therein; an energizable light source positioned within said compartment for generating radiant energy, said light source consisting of a high intensity lamp; electrical conduit means connected to said lamp for energizing same; and means coacting between said compartment and said combustion chamber for permitting transmission of radiant energy from said compartment to said combustion chamber and for causing concentration of said radiant energy at a selected location within said combustion chamber to cause ignition of the fue1air mixture.
Claim 2
Dependent Claim 143 words
In an internal combustion engine having housing means defining a cylinder therein and a piston slidably disposed within said cylinder, said piston and said cylinder cooperating to define a combustion chamber, and an ignition device coacting with said combustion chamber for igniting a fuel-air mixture therein, the improvement wherein said ignition device comprises: a support housing fixed to said housing means and defining a compartment therein; an energizable light source positioned within said compartment for generating radiant energy, said light source consisting of a high intensity lamp; electrical conduit means connected to said lamp for energizing same; and means coacting between said compartment and said combustion chamber for permitting transmission of radiant energy from said compartment to said combustion chamber and for causing concentration of said radiant energy at a selected location within said combustion chamber to cause ignition of the fue1air mixture.
Claim 3
Dependent Claim 37 words
An internal combustion engine according to claim 1, further including reflector means positioned within said compartment in the vicinity of said light source for reflecting the radiant energy generated thereby in a direction toward said combustion chamber.
Claim 4
Dependent Claim 12 words
An engine according to claim 2, wherein said lamp is a strobotron.
Claim 5
Dependent Claim 40 words
An internal combustion engine according to claim 1, wherein said coacting means comprises lens means for sealingly isolating said compartment from said combustion chamber while permitting transmission of radiant energy therethrough and concentration of said radiant energy at said location.
Claim 6
Dependent Claim 25 words
An internal combustion engine according to claim 4, further including means mounting said lens means for adjusting the position thereof relative to said light source.
Claim 7
Dependent Claim 37 words
An internal combustion engine according to claim 4, further including reflector means positioned within said compartment in the vicinity of said light source for reflecting the radiant energy generated thereby in a direction toward said combustion chamber.
Claim 8
Dependent Claim 15 words
An engine according to claim 6, wherein said compartment is maintained under a partial vacuum.
Claim 9
Dependent Claim 22 words
An internal combustion engine according to claim 1, further including means operatively connected to said light source for causing intermittent energization thereof.
Claim 10
Dependent Claim 51 words
An engine according to claim 1, wherein said housing means has a threaded opening formed therein and communicating with said combustion chamber, and said suppOrt housing comprising a sleevelike member closed at one end and open at the other end thereof, said other end being threadably engaged with said threaded opening.
