Title: Kimitaka Saitoh: Innovator in Internal Combustion Engine Technology
Introduction
Kimitaka Saitoh is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of internal combustion engine technology, holding 2 patents that showcase his innovative approach to engine control systems.
Latest Patents
One of his latest patents is a controller for internal combustion engines that optimizes valve timing during specified self-ignited combustion regions. This invention allows for a negative valve overlap period, where both the exhaust and intake valves are closed. During this period, direct fuel injection is performed to reform the fuel, followed by port injection to control engine output. This method stabilizes self-ignited combustion conditions by detecting the fuel reform degree and adjusting the fuel injection quantity accordingly.
Another patent by Saitoh involves an ON-ignition signal output from an ignition control portion. This signal is generated from a specific timing after the power stroke to charge a capacitor. If the ion-output value detected during the negative valve overlap period exceeds a threshold, it indicates a drop in applied voltage at the spark plug. The ON-ignition signal is then reissued to charge the capacitor before the intake valve opens, enhancing engine performance.
