EGR technology enables car manufacturers to produce greener, more efficient vehicles through reduced exhaust gas emissions, increased engine performance and improvement in fuel consumption.
EGR technology uses NOx (nitrogen oxides) reduction techniques used in both petrol and diesel engines.
The module recirculates a portion of the engine's exhaust gas back to the engine cylinders.
By intermixing the incoming air with re-circulated exhaust gas, the mix is diluted, lowering the peak combustion temperatures and reducing the amount of excess oxygen.
The EGR valve control system serves to limit the generation of NOx, primarily formed due to the presence of oxygen and high-temperatures.
C-Mac manufactures thick-film ceramic hybrid circuit modules which provide the sensing and control circuitry for the EGR valve system actuation and timing.
Ken Henderson, General Manager - Automotive, C-Mac, said, "Over the past few years, new and stringent emission regulations in Europe and North America have been driving an increased uptake of exhaust gas recirculation (EGR) technology in the automotive market".
"C-Mac is positioned to supply to this growing market as it is the first company to manufacture thick-film ceramic hybrid circuitry for this application, ensuring its suitability for high reliability operation in the harsh, high-temperature environments found in the engine compartment of the vehicle".
