Latest Patents

Ohtsuka holds 1 patent for his invention of an engine controller. This controller estimates the temperature of exhaust gas and adjusts the engine's operation accordingly. It changes the air-fuel ratio to either a stoichiometric or leaner mixture. The controller utilizes sensor signals to calculate combustion progress and estimate exhaust temperature. When the air-fuel ratio is stoichiometric, it estimates exhaust temperature based on combustion progress, engine temperature, and a defined relationship between combustion progress and exhaust temperature. Conversely, when the air-fuel ratio is lean, it employs a different relationship for estimation.
