Title: Hiromu Sugano: Innovator in Engine Control Technology
Introduction
Hiromu Sugano is a prominent inventor based in Higashihiroshima, Japan. He has made significant contributions to the field of engine control technology, holding a total of 8 patents. His innovative work focuses on improving engine performance and efficiency, particularly in the automotive industry.
Latest Patents
Sugano's latest patents include a start controller for engines and a stop position controller for engines. The start controller is designed to reduce the torque consumed by a starter when starting an engine. It features a stop position sensor that detects the position of a piston in each cylinder at engine stop time, along with an intake pressure sensor that measures the intake pressure in the passage. The processor determines if the piston position is within a specified target range after the engine has stopped. If the piston position is out of range and the intake pressure is lower than atmospheric pressure, the engine can still be started by a motor, even if the start conditions are not met.
The stop position controller incorporates an intake variable valve timing mechanism (VVT) that collectively adjusts the intake valve close timing for multiple valves. It includes a control device that manages the engine, which consists of several injectors and the intake VVT. When a specified engine stop condition is met, a fuel cut is executed to halt fuel supply to the cylinders. After the fuel cut, the intake VVT is controlled to ensure that the retarded amount of intake valve close timing for a cylinder in a compression stroke is larger than that for a cylinder in an expansion stroke.
