Latest Patents

Among his recent innovations, Saito has developed various methods for controlling engines through advanced fuel injection techniques. One of his key patents focuses on a method for motoring an engine and injecting specific fuel for analysis to determine its properties by measuring cylinder pressure. This method involves a series of coordinated actions including the timing of fuel injection after the cylinder intake valve is closed. The controller in this method acquires a crank angle period from fuel injection start to when the cylinder pressure reaches a reference level, enabling the determination of fuel properties by comparing this with a reference crank angle period.

Additionally, Saito's patented engine controlling method enhances engine performance by analyzing the pressure inside the cylinder. This involves injecting fuel for analysis at a specific timing post valve closure, followed by signal output from an in-cylinder pressure sensor. The controller compares pressure values to classify the fuel properties, ensuring optimized engine functionality.
