Title: Dennis R Zitny: Innovator in Engine Technology
Introduction
Dennis R Zitny is a notable inventor based in Dearborn, MI (US). He has made significant contributions to engine technology, particularly in the area of pressure sensing. His innovative work has led to the development of a unique patent that enhances the accuracy of engine performance measurements.
Latest Patents
Dennis R Zitny holds a patent for an "Engine cylinder pressure sensor with thermal compensation element." This invention features a transducer housing designed for mounting in a port within an engine combustion chamber. The design includes a metal diaphragm that is exposed to combustion gases. The pressure from these gases is transmitted through an aluminum coupling disc, which deflects a simply supported beam member. This beam member is constructed from refractory material and has epitaxially grown crystalline piezoresistors on one surface, connected in a bridge circuit and secured to a ceramic mounting disc. The aluminum coupling disc's high coefficient of thermal expansion ensures that a preload is maintained on the beam member, improving accuracy despite the low thermal expansion of the ceramic mounting disc. An alternate embodiment includes an expansion ring made from a material with a high coefficient of thermal expansion, which supports the mounting disc and maintains the preload between the beam member and a cup diaphragm.
