With a total of 2 patents, Toryu's innovations reflect his commitment to enhancing vehicle performance and environmental sustainability.

Latest Patents

One of Toryu's latest patents is a catalytic converter designed for exhaust gas purification. This innovative device is adapted to retard spark timing, which increases the temperature of the converter catalyst when a temperature sensor detects low exhaust temperatures. The system includes a vacuum advance mechanism that responds to intake manifold vacuum, allowing for optimal spark timing adjustments. This ensures that when the exhaust temperature falls below a predetermined value, atmospheric air is admitted into the vacuum advance mechanism, thereby increasing the catalyst temperature for improved emissions control.

Another significant patent by Toryu is an after-burning preventive system for internal combustion engines. This system features an accumulator chamber that communicates with the atmosphere through a restricted passage. The design includes a pressure control valve that opens the passage in response to pressure differences, maintaining the vacuum differential between the accumulator and vacuum chambers. This innovation is crucial for ensuring efficient engine operation and reducing emissions.
