Latest Patents

Nakamura holds a patent for a torch ignition type internal combustion engine. This engine design features no intake valve in the auxiliary combustion chamber. The engine comprises a cylinder, a cylinder head, and a reciprocating piston that fits snugly within the cylinder. The main combustion chamber is defined between the cylinder head and the end face of the piston, equipped with intake and exhaust valves to control the respective ports. An auxiliary combustion chamber is integrated into the cylinder head, connected to the main chamber via a passage. The ignition plug, with sparking electrodes, is located in this passage. The auxiliary combustion chamber's volume ratio is between 0.0106:1 to 0.0137:1 relative to the piston displacement volume. The passage's cross-sectional area ratio ranges from 0.009:1 to 0.023:1 compared to the piston end face area, and the engine operates with a compression ratio between 8.0 and 9.5. This innovative design aims to improve combustion efficiency and reduce emissions.
