Latest Patents

Nomura’s latest patent revolves around an induction system for internal combustion engines. This innovation comprises several embodiments designed to improve charging efficiency, particularly at low speeds. Each design features a plenum chamber located upstream of the engine throttle valve, alongside a reed-type check valve that allows air to flow into the plenum chamber. This mechanism is vital for maintaining airflow and optimizing performance at lower speeds. Additionally, the integration of a supercharger into some embodiments discharges air into the plenum chamber, thus minimizing pulsation effects transmitted from the supercharger to the engine intake ports. The clever placement of the reed-type check valve helps to mitigate pulsations that could disrupt airflow from the intake ports back to the check valve. Furthermore, in several embodiments, an air cleaner housing is formed integrally with the plenum chamber, resulting in a more compact design.
