    摘要： An apparatus and method for pretreatment of fuel in a combustion device such as an internal combustion engine, in which a fuel is partially combusted by a catalytic reaction to form a high temperature hydrogen-rich product gas, which gas is thereafter directly injected into an oxidizing atmosphere in the combustion chamber of the device. A composite catalyst is utilized constituted by diverse catalytic materials to achieve different contributing effects on the catalytic combustion process by the respective materials, particularly the inhibition of coke formation by the use of magnesium oxide, and platinum to achieve low temperature ignition and partial combustion of a fuel-oxidizer mixture.

    摘要： A torch ignition apparatus and method, the apparatus including a secondary, torch ignition piston interconnected to the primary piston and operable to produce through compression ignition of a carbureted fuel/air mixture a jet of hot gases capable of igniting a fuel and air mixture compressed in a primary combustion chamber by the primary piston. The apparatus also includes a secondary fuel system for supplementing a low ratio fuel/air mixture in the combustion chamber and a novel hoop valve and exhaust port system for providing a unique, highly efficient flow-through system for exchanging gases in the combustion chamber.

    摘要： Disclosed herein is apparatus including all of the components present in a conventional internal combustion engine such as body forming cylinder walls that define a primary combustion chamber, a piston reciprocable in the cylinder between compression and power strokes, intake means for introducing fuel charges into the primary combustion chamber, ignition means for igniting fuel charges and exhaust means for removing residual gases from the primary chamber after ignition of each fuel charge. Added to these conventional engine components is a housing that defines an auxiliary combustion chamber and an orifice that provides communication between the primary and auxiliary combustion chambers. During operation of the engine, both the primary and auxiliary chambers are charged with a fuel mixture after which the charge in the auxiliary chamber is ignited producing a jet of turbulent flame that passes through the orifice into the primary chamber inducing complete and uniform mixing and burning of the fuel mixture retained thereby. Optimum performance of the engine is insured by a purging mechanism that moves through the auxiliary combustion chamber after each ignition cycle so as to force residual gases out of the orifice which therefore functions also as an exhaust port. This purging provides a free volume for receiving an undiluted fresh fuel charge.
