He holds 2 patents that showcase his innovative approach to solving complex engineering challenges. His work primarily focuses on enhancing the performance and efficiency of internal combustion engines.

Latest Patents

One of Belfi's latest patents is an engine cylinder pressure sensor with a thermal compensation element. This invention features a transducer housing designed for mounting in an engine combustion chamber, utilizing a metal diaphragm exposed to combustion gases. The pressure from these gases is transferred through an aluminum coupling disc, which deflects a simply supported beam member made of refractory material. This beam member has epitaxially grown crystalline piezoresistors connected in a bridge circuit, secured to a ceramic mounting disc. The design ensures improved accuracy by maintaining a preload on the beam member, compensating for the low thermal expansion of the ceramic mounting disc.

Another significant patent is the water-cooled viscous fan drive. This invention includes a fluid coupling assembly located within a coolant cavity defined by an engine block of an internal combustion engine. The fluid coupling comprises an input coupling assembly and an output coupling member, which work together to optimize torque capacity. The input coupling assembly also serves as the water pump for the engine, integrating multiple functions into a single component.
