Our emissions retrofit solutions extend beyond Cat® machines, trucks and school buses to include stationary & portable engines, too. Stationary & portable engines are used in power generation, air compression, water pumps and gas compression applications. Caterpillar technology for emissions reduction for these products is similar to solutions used for machines, trucks, and buses. The end result is lower airborne emissions proving, once again, that retrofit technology is a cost-effective solution to reduce emissions for older engines that were not designed to meet today's tighter emissions standards.
