Engine Emission control system for public buses in Bogota

A project to reduce emissions from heavy-duty vehicles (TransMilenio public buses) has just started in Bogota with the support of the Swiss embassy, the VERT Association, CPK Automotive and DPF manufacturer. The main goal is the reduction of air pollution in some of the larger cities of Latin America.

Bogota is one of the cities taking part in this Latin American “Climate and Clean Air” project (Programa Clima y Aire Limpio en Ciudades de América Latina)

CPK Automotive will be working closely together with local authorities, specialist teams, public-sector representatives, the transport sector and universities.

In the first stage of the project, 16 test vehicles were carefully selected to collect temperature data. The particulate filters for a range of applications were identified and will be installed after the analysis of these measured data. All the filters will be equipped with electronic control units (incl. GSM/GPRS Modules) supplied by CPK.

In general, CPK Automotive’s electronic control unit (ECU) collects data (back pressure, temperature) from the diesel particulate filter installed in a vehicle and will contribute data for the compilation of a data base of comparable data for all vehicles.

The authorities hope by means of this pilot scheme to establish the technical framework that will enable them to identify, install, operate and maintain systems that will make the diesel engines used in TransMilenio and SITP public transport buses cleaner and more environmentally friendly. If all goes well, the project will be rolled out to cover most of the buses in Bogota.

During the second phase, follow-up and evaluation tasks will be performed, bearing in mind the different technical, economic and logistic aspects identified during the execution of the first stage of the pilot scheme. In the follow-up stage, the data base compiled by CPK will be used to select the best solutions for each type of vehicle.
