Title: Geraki Marek: Innovator in Engine Exhaust Emissions Measurement
Introduction
Geraki Marek is a notable inventor based in Ann Arbor, MI (US). He has made significant contributions to the field of exhaust emission analysis, focusing on improving the accuracy of emissions measurement systems. His innovative approach addresses critical environmental concerns related to engine exhaust emissions.
Latest Patents
Marek holds a patent for an "Engine exhaust emissions measurement correction" system. This invention provides an exhaust emission analysis system that includes an exhaust and dilution gas source, which respectively supply exhaust and dilution gases. The system features a dilution unit with flow devices, such as mass flow controllers, that are fluidly connected to the gas sources. The metering device in the mass flow controllers defines the gas flow rate from each source. The gases are mixed to create a diluted exhaust gas with an initially incorrect dilution ratio. A water measurement device analyzes the water content of the exhaust gas after dilution. The system sends a water content dilution signal to a control device, which calculates an adjustment factor. This factor allows the system to send a flow rate command signal to the exhaust gas mass flow controller, correcting the dilution ratio. This innovative approach also provides corrections to particulate samplers.
