The unusual Colombian topography, when compared to the rest of the globe, forces all vehicles to constantly adapt their mechanisms to the different altitude variations within some relatively short periods of time and distances, thus causing the previously explained performance setbacks. Now, the attempt to modify car operational features to cities like Bogotá by adjusting the spark advance timing and other similar procedures, has shown to be useless in preventing the engine rattle noise when going to warmer lands or the pulling effect when momentum is lost at applying brakes on a street corner, and even the " motor choking reaction when stomping the accelerator in high-powered engine vehicles.
By installing the Marclais ecological valve to the vehicle, most of the previously mentioned hindrances are significantly reduced because the valve automatically regulates itself to allow proper engine oxygenation at different altitudes. Therefore the EV will prove to be a very useful mechanism for vehicles running at high altitudes like moorlands (rather than at sea level topographies), by allowing a greater airflow proportion into the engine. Nor is it necessary to make additional adjustments to install the ecology valve in the vehicle, or to worry about disassembling or calibrating it when traveling to warmer lands, because, as mentioned previously, the EV automatically self-adjusts to the varied heights above sea level.
