Although this probably doesn’t look like much
for many OEMs it is going to be absolutely critical for them by round about September 1, 2017, in Europe to meet the Euro 6c emissions regulations.
And you know that since September 3, 2015, when a certain European OEM acknowledged to the U.S. EPA that there was a little something in the way of meeting existing emissions regulations properly, OEMs are going to be exceedingly keen on making sure that what comes out of their tailpipes is what they say it is (and that it will get to the tailpipe in legitimate manner).
The objects in question are oval-shaped gasoline particulate filters that Tenneco recently launched for vehicles with gasoline direct-injection (GDI) engines.
Many OEMs are turning to GDI engines—where the fuel is injected directly into the cylinders—because they can improve fuel economy, which means reduced CO2 emissions. . . but not lower particulate emissions. That’s because there are shorter in-cylinder fuel/air mixing times.
According to Tenneco, “Advanced fuel injection strategies are currently used to control gasoline particulate emissions in-cylinder, but they are designed for a particular emission test cycle and may be less effective under real driving conditions.”
Do you think any OEM is going to continue to depend on a strategy “for a particular emission test cycle” that doesn’t square with “real driving conditions”?
I don’t, either.
Anyway, this Tenneco filter is based on the same type of wall-flow substrates as those used for diesel particulate filters, something that the company has had in series production for some time. The gasoline particulate filter can be included in the exhaust system with the three-way catalyst, or the catalyst coating can be directly applied to the filter substrate to create a four-way catalyst.
Either way, those pesky particulates are handled.
