Complete Coach Works (CCW) is in the process of completing the installation of Diesel Particulate Filters (DPF’s) on 20 coach buses for El Paso-Los Angeles Limousine Express Inc. (EPLA).

The project ensures that coaches operated by EPLA meet particulate emission standards for diesel-powered vehicles set by various regulatory agencies.

Several days of data logging on each engine are performed to obtain crucial information about the vehicle's exhaust system.

The data logger, which is temporarily installed on each vehicle, documents exhaust temperatures during normal engine operation. Exhaust temperatures, which can be influenced by vehicle speed, load, idling, ambient air temperatures and driver tendencies, can impact the operation of the proper filter.

After data logging, each engine undergoes an assessment for flaws such as oil leaks, heavy smoke and exhaust leaks.

The assessment is then preceded by the installation of the DPF, which is a three-day process. Every EPLA coach receives the same type of passive filter, which can be removed, cleaned and replaced while the coaches are in the shop for routine maintenance.

"These are tour buses. They have a tight allocation for where the filter can be mounted, but even with that challenge we are able to complete a successful installation," stated CCW Representative Mando Aguirre.

The project allows CCW to prove its ability to provide sound, secure installations during a short time frame to avoid affecting the company's scheduled operations.
