<p>An internal combustion engine that burns fuel from a fuel source, and an engine including a block assembly with a piston cylinder, a combustion chamber connected to the piston cylinder, and an air/fuel mixing area that communicates with the combustion chamber for delivering an air/fuel mixture to the combustion chamber. A fuel delivery system is connected to the block assembly, and the fuel delivery system is adapted to deliver a selected amount of fuel into the mixing area for mixing with air therein to provide an air/fuel mixture having an air-to-fuel ratio in the range of approximately 20:1 to 45:1, inclusive. A spark plug is connected to the block assembly and positioned to generate a spark in the combustion chamber to detonate the air/fuel mixture. The spark plug has a center electrode and a ground electrode axially spaced apart from each other by a spark gap in the range of approximately 1.8 mm to 3.0 mm. The center electrode of one embodiment is an Inconell 600 steel alloy electrode having a diameter in the range of 4.0 mm to 7.5 mm. In one embodiment, an electronic control module (ECM) is coupled to the engine to control operating parameters, and the ECM has a PROM that is programmed to control formation of the air/fuel mixture with the air-to-fuel ratio in the range of approximately 20:1 to 45:1, inclusive.</p> |
