Abstract The study investigated the extent and source of irregularities related to the measurement of NOx emissions from methanol cars. Corrective measures also were explored. It was observed that NOx chemiluminescent analyzers respond to methanol and formaldehyde after being exposed to high concentrations of methanol and formaldehyde over extended periods. This response can cause significant errors in the measurement of NOx from methanol cars which have inherently elevated concentrations of exhaust methanol and formaldehyde. The most effective way of eliminating the spurious response is to clean the analyzer's reaction chamber regularly when testing vehicles which are being operated on methanol fuels.
