Title: B M Yen: Innovator in Fuel Injection Technology
Introduction
B M Yen is a notable inventor based in Columbus, IN (US). He has made significant contributions to the field of fuel injection technology, holding 2 patents that showcase his innovative approach to enhancing fuel injector performance.
Latest Patents
One of his latest patents is an injection rate shaping nozzle assembly for a fuel injector. This invention includes a closed nozzle valve element and a rate shaping control device that features an injection spill circuit. The purpose of this assembly is to spill a portion of the fuel to produce a predetermined time-varying change in the flow rate of fuel injected into a combustion chamber. The spill circuit consists of a spill passage that is integrally formed in the nozzle valve element. The rate shaping control may also include a spill valve that regulates the spill flow through the spill circuit, allowing for a low injection flow rate followed by a high injection flow rate. Additionally, the spill passage can communicate with the injector nozzle cavity between injection events or be blocked to prevent spill flow during those events. The rate shaping control device may further incorporate a spill accelerating device, such as a spill chamber formed in the nozzle valve element, to create a rapid increase in the spill flow rate. Another embodiment of the rate shaping device may include a throttling passage that is integrally formed in the nozzle valve element, which varies the rate at which fuel pressure in the nozzle cavity increases, thereby affecting the flow rate through the injector orifices.
