Title: Naoki Shimazaki: Innovator in Diesel Engine Technology
Introduction
Naoki Shimazaki is a prominent inventor based in Fujisawa, Japan. He has made significant contributions to the field of diesel engine technology, holding a total of 6 patents. His innovative designs focus on improving combustion efficiency and performance in diesel engines.
Latest Patents
One of his latest patents involves a diesel engine featuring a reentrant type cavity depressed in the top of a piston. This design includes fuel injection means that directs fuel towards the cavity and an exhaust gas recirculation (EGR) means that recirculates a portion of the exhaust gas into the combustion chamber. The control device in this engine regulates the fuel injection timing and the EGR ratio or quantity, enabling favorable premixed combustion. This ensures that the injected fuel ignites near the compression top dead center of the piston, enhancing combustion efficiency even when switching to diffuse combustion.
Another notable patent describes a diesel engine that comprises a fuel injection device, an EGR device, and a control device. This system is designed to achieve premixed combustion, where the mixture is ignited after the fuel injection ends. The engine is equipped with a detection unit that monitors the ignition timing of the mixture. If the actual ignition timing deviates from the preset optimum, the control device adjusts the fuel injection timing to align with the optimal ignition timing.
