Latest Patents

One of his latest inventions is a fuel property detection apparatus. This apparatus detects fuel properties based on the cetane number and density of a tested fuel. It examines the tested fuel in terms of ignition timing. If the ignition timing is earlier than a threshold, the fuel is identified as having a standard cetane number. Conversely, if the ignition timing is later than the threshold, it is identified as having a low cetane number. The apparatus increases the advance angle of the ignition timing to yield a greater difference between light property fuel and heavy property fuel. When the advancement of the ignition timing exceeds a threshold, the fuel property is identified as heavy; otherwise, it is identified as light.

Another notable invention is a gaseous fuel injector that uses liquid fuel as a lubricant and pressure-transmitting medium. This fuel injector injects high-pressure gaseous fuel directly into an engine cylinder. A small amount of liquid fuel lubricates the sliding portions of the injector while also serving as a medium for transmitting driving force. The injector features a nozzle member with injection holes and a needle that is driven by the pressure of the liquid fuel in a control chamber. The pressure is regulated by a switching valve, which is actuated by an electromagnetic or piezoelectric actuator. The liquid fuel is injected alongside the high-pressure gaseous fuel after lubricating the sliding components.
