Latest Patents

Shimizu's latest patents include innovative designs for marine engines. One of his patents describes a marine engine that features a piston and a compression ratio controller. This controller is designed to lower the top dead center position of the piston when the engine rotation speed falls within a predetermined resonance occurrence range. This innovation helps to reduce the geometrical compression ratio and suppress resonance stress caused by torsional vibrations, all while maintaining thermal efficiency.

Another patent by Shimizu involves a marine engine equipped with an air controller that supplies compressed air to the combustion chamber during an upstroke of the piston after a crash astern signal is activated. This design also includes a fuel controller that halts fuel supply during the crash signal and resumes it after the crankshaft rotates backward. Additionally, a compression ratio controller is integrated to adjust the top dead center position of the piston in response to the crash signal.
