Kenji Tanimura is a prominent inventor based in Hiroshima, Japan, known for his significant contributions to engine control technology. With a total of 10 patents to his name, Tanimura has made strides in enhancing the efficiency and performance of automotive engines. His work is particularly recognized within the automotive industry, where he has developed innovative solutions that address common challenges faced by engine systems.

Latest Patents

Among Tanimura's latest patents is the "Start Controller for Engine." This invention provides a start controller capable of reducing the torque consumed by a starter when starting an engine. The controller includes a stop position sensor that detects the position of a piston in each cylinder at engine stop time, an intake pressure sensor that measures the intake pressure in the passage, and a processor that determines if the piston position is within a specified target range after the engine has stopped. If the piston position is out of the target 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 fully met.

Another notable patent is the "Stop Position Controller for Engine." This invention features an intake variable valve timing mechanism (VVT) that collectively adjusts the intake valve close timing for multiple valves. The control device manages an engine with several injectors and the intake VVT. When a specified engine stop condition is met, a fuel cut is performed to halt the fuel supply into the cylinders. The intake VVT is then controlled to ensure that the retarded amount of the intake valve close timing before stopping a compression stroke cylinder is greater than that of an expansion stroke cylinder.
