Title: The Innovations of Saburo Nakamura
Introduction
Saburo Nakamura is a notable inventor based in Higashihiroshima, Japan. He has made significant contributions to the field of diesel engine technology, holding a total of 2 patents. His work focuses on improving the efficiency and performance of diesel engines through innovative designs.
Latest Patents
Nakamura's latest patents include an intake system for diesel cycle engines and a fuel injection system for diesel engines. The intake system features a timing valve that operates during the engine's starting and warming-up period under cold conditions. This timing valve opens at the end of the intake stroke, creating a strong suction pressure in the combustion chamber. When the valve opens, intake air rushes into the chamber at high speed, compressing the air and increasing its temperature. The valve's operation is responsive to the suction pressure, ensuring optimal performance.
The fuel injection system comprises a pintle type fuel injection nozzle with a valve needle that moves between two positions. This system includes fuel supply means for delivering pressurized fuel and a plunger member that interacts with the valve needle. The design allows for a stepwise change in the valve opening pressure based on the amount of lift of the valve needle. Additionally, the system features pre-lift change means and operating condition detecting means to enhance engine performance.
