## Abstract

The ability of the ignition piston engine is to use the disel technic of igniting the fuel air mixture by compression with out using an injector. The ignition piston engine can burn a leaner air fuel mixture than any other engine there by giving a cleaner exhaust and more economy. The ignition piston engine can burn any type of fuel that flows in air and is combustable by heat; like gasolene, diesel, propane, natural gas, and kerosene in any desired air fuel mix. And it can do it with out using a spark plug.

## Claims

### Claim 1

An internal combustion engine piston operation compromising; two parallel pistons adjacent to each other driven by the same crankshaft stroking in unison; one piston small and other large; the large has low compression approximately eight to one; the small piston has high diesel type compression; when the large piston is past top dead center eight degrees and the small piston is eight degrees before top dead center; the small ignition piston 1 compresses the fuel-air mixture to combustion; a relief valve 3 in the head 11 above the small piston is forced open by the combustion pressure; when the relief valve 3 is forced up it leaves an open channel 8 in the head over to the combustion chamber 9 of the low compression large piston 2; the combustion fire from the high-pressure small piston 1 travels through the channel 8 over to the combustion chamber 9 of the large piston 2; the fire entering the large piston combustion chamber 9 causes the air-fuel mixture to explode;

### Claim 2

Because ignition is accomplished by compression there is no spark plug electrical system or a high-pressure injector system.

### Claim 3

A new design conrod 18 for the high compression ignition piston 1; it puts the piston push torque past the top dead center even when the conrod crankshaft journal 15 is eight degrees before the top dead center.
