ontinental Controls Corporation (CCC) has introduced a new ultra-low emissions system which offers automatic compliance without the normally required operator intervention. The key to its breakthrough for this system is the addition of a NOx sensor downstream of the non-selective catalytic converter (NSCR). This NOx sensor provides feedback and confirmation that the engine is running well, the catalyst is working correctly and the entire emissions control system is working as it should.
Now, by adding the CCC catalyst monitor with the NOx sensor in the engine exhaust and providing dynamic feedback to the AFR, it is possible to keep the engine in compliance over a much longer time frame. CCC vice-president Rick Fisher said: “During our field test at Fontana Wholesale Lumber on their Waukesha Engine, we left the engine completely alone for more than three months and we were still at the lowest required levels of both NOx and CO without any operator intervention. We believe that this may be the first time that this has been achieved.”
