An engine includes an engine housing defining a pair of cylinders, a pair of ignitor cylinders and a crankcase, a pair of cylinder heads connected to the engine housing and enclosing the pair of cylinders, a pair of spark plugs connected to the pair of cylinder heads and in communication with the pair of cylinders, a piston assembly in communication with the pair of cylinders, a rocker arm connected to the piston assembly, a connecting rod connected to the rocker arm, and a drive shaft disposed within the crankcase and connected to the connecting rod, a pair of ignitor cylinder plugs fit within the pair of ignitor cylinders, ignitor piston rod apertures formed though the engine housing, and rod aperture plugs fit within the piston rod apertures.

An engine with mesh anchored combustion with a pressure regulating auxiliary chamber for providing controlled internal combustion at essentially a constant pressure. The engine comprises a main cylinder and piston with an auxiliary chamber and piston integral therewith. The auxiliary chamber is adjacent to the main cylinder head, connected thereto through a relatively narrow throat. A mesh is positioned in the throat at the boundary of the main cylinder and the auxiliary chamber. Accordingly, when the main piston compresses a charge in the main cylinder during its compression stroke, the charge is pushed through the mesh into the auxiliary chamber. The auxiliary chamber piston pushes the charge in the reverse direction back through the mesh into the main cylinder. As the charge passes through the mesh back into the main chamber, its combustion forces the main piston back down toward bottom dead center.

An internal combustion engine designed to provide a Leaschauer Combustion Process including injecting processed pre-mist fuel into extreme air pressure compressed air in the main cylinder. The fuel injection moment is accurately controlled and timed to enable extreme high compression combustion, so that the engine is enabled to utilize low octane fuel without pre-detonation.
