Component manufacturer requests gaseous and particulate emissions sampling to validate performance

A heavy duty diesel aftermarket manufacturer wanted to demonstrate the effectiveness of their engine cooling components to one of their large fleet contractors. The testing required monitoring hundreds of temperature and pressure data points on and around the vehicle in a wind tunnel while CleanAir monitored the diesel emissions. The testing was to be performed before and after vehicle modification. The size and nature of the truck was such that only a few wind tunnels in the country could accommodate the vehicle and most of those do not have emissions monitoring capability.

CleanAir mobilized state of the art monitoring equipment to a large Midwest wind tunnel contracted for the testing. This wind tunnel is booked almost 100% of the time and we were given a 36-hour window over a weekend to set-up and run an extensive series of tests at several different load and temperature conditions and then come back at a later date and repeat the whole series.

If the demonstration is successful the resulting sale of the aftermarket cooling components will be large enough to justify the expenses incurred in this demonstration by at least ten fold. It is also interesting to note that our portions of the project (the diesel emissions) were not even required to meet the client’s objectives. The client proactively, and wisely so we believe, knew that emissions issues facing diesel engines were only getting tighter and they wanted to simultaneously demonstrate that their components did not adversely affect emissions and may in fact improve them. The second phase of testing has not been conducted yet.
