RESEARCH RATIONALE Road transport is one of the major contributors to the environmental pollution. There are many sources and types of substances emitted by road transport, but for the vehicles with the internal combustion engine the main source of pollution is the tail-pipe exhaust emissions. A catalytic converter is the most common and efficient method to mitigate exhaust tail-pipe emissions. The efficiency of a catalytic converter can deteriorate with time and car’s mileage. In the countries with aging car fleets, without a compulsory, periodic and metered in-service emissions testing (like NZ), such deterioration can further increase the environmental pollution. This short presentation discusses the results of a pilot test performed at Unitec to evaluate the efficiency of catalytic converters on older cars in New Zealand.
