Latest Patents

One of Ashizawa's latest patents is a start control system for internal combustion engines. This system controls the first and second discharge actions of ignition apparatuses to optimize engine start-up. The first discharge action ignites the mixed gas in multiple cylinders, while the second discharge action generates ozone. The first discharge action occurs immediately after cranking begins, specifically in the first and second cylinder groups. The second discharge action is performed before cranking, targeting at least one cylinder in the second cylinder group.

Another notable patent is an exhaust gas purification system for internal combustion engines. This system activates the catalyst when the engine starts and the catalyst temperature is below the activation threshold. The activation control involves controlling the first and second discharge actions of ignition apparatuses. The first discharge action ignites the mixed gas in the cylinder, while the second discharge action generates ozone. The first discharge action is executed in every cylinder, while the second discharge action is performed in cylinders other than the initial combustion cylinder.
