Abstract: 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.

Abstract: An internal combustion engine designed to provide a Leaschauer Combustion Process (LCP), including: at least one main piston housed in a main cylinder; a main axle (rotor) shaft; configured to enable an LE four cycle process; configured to enable air to fill said main cylinder prior to compression of the main cylinder; means for providing Specific Extreme Air Pressure (EAP) compressed air in said cylinder housing said main piston to dramatically exceed Specific fuel/air (Mixture) Detonation Pressure (SMD); built to withstand extreme stress applied by the Extreme Air Pressure on its main structure and moving parts; means for providing Processed Pre-Mist Fuel (PMF); means for injecting the processed pre-mist fuel into the specific Extreme Air Pressure (EAP) compressed air in the main cylinder to create a uniform unstable PRE Mist Mixture PMM), during a restricted defined window close to UDP of the main cylinder, where pressure and heat are at peak values, with a strictly defined phase; whereby said fuel inject

Abstract: Disclosed herein is an Internal Combustion Engine (ICE) termed the Leaschauer Engine (LE). The Leaschauer Engine (LE) is a single or multiple step compression cycle ICE machine, employing the Pressure/Heat Detonation Principle (Diesel Principle). The Leaschauer Engine employs extreme combustion pressure to achieve high combustion efficiency operation without risking a pre-detonation condition.

Abstract: Disclosed herein is a novel ICE termed the Leaschauer Engine (LE). The Leaschauer Engine (LE) is a single or multiple step compression cycle ICE machine, employing the Pressure/Heat Detonation Principle (Diesel Principle). The Leaschauer Engine differs significantly from a conventional ICE machine by its ability to employ extreme combustion pressure to achieve high combustion efficiency operation without risking a pre-detonation condition.
