His innovative approach addresses critical challenges in exhaust gas purification.

Latest Patents

Jun-hee Won holds a patent for an "Engine control method for maintaining performance of oxidation catalyst." This patent describes a method where fuel of a compressed natural gas engine is burned under a lean-burn condition with an air-fuel equivalence ratio of less than or equal to 1. The method determines the activation of the oxidation catalyst necessary for purifying the engine's exhaust gas. It also assesses the need for a regeneration mode to recover the catalytic activation based on the oxidation catalyst's activation state and the engine's operating conditions. Notably, when the oxidation catalyst is inactive and the engine speed is below a predetermined threshold, the air-fuel equivalence ratio is increased to a range of 1.10 to 1.20.
