The Role of Diesel Ceramic Coatings in Reducing Automotive Emissions and Improving Combustion Efficiency

Diesel ceramic coatings are now being applied to automotive engine components such as valves, pistons and heads to eliminate visible smoke, inhibit the formation of NOx, reduce CO and particulate emissions and improve combustion efficiency. Recently, specially designed software has been installed by trucking and transit companies to monitor the performance of the diesel ceramic coatings under actual operating conditions, with subsequent testing on EPA-certified dynamometers. The coatings are being evaluated for their ability to control particulate emissions (with and without particulate traps), for emissions in exhaust gases, for smoke, horsepower, speed in miles per hour, exhaust temperature and fuel rate in miles per gallon. These results, as well as the properties of the diesel ceramic coatings which effect these changes in diesel combustion, will be discussed.
