Latest Patents
Kawaguchi's most recent patents include an "Exhaust gas control apparatus for internal combustion engine" and an "Exhaust gas purification system for an internal combustion engine."
The exhaust gas control apparatus aims to decrease the amount of nitrogen oxides (NOx) emitted into the atmosphere. This innovative system calculates the ammonia adsorbed on an SCR catalyst by subtracting the ammonium nitrate produced at the start of an internal combustion engine from the total ammonia adsorbed. The invention enhances efficiency by controlling the flow of NO based on the estimated NOx purification rate.
The exhaust gas purification system features a low-pressure EGR mechanism and a selective reduction type catalyst located downstream in the exhaust passage. This invention includes a supply device that delivers ammonia-derived compounds to the catalyst and is designed to optimize the supply when the low-pressure EGR valve is open, thereby improving the exhaust gas purification process.
