Exhaust emissions from gasoline vehicles have been dramatically lowered due to the recent global environmental demand. Such situation makes it very difficult for to measure the emissions by the conventional measurement system, because the concentrations of gasoline vehicle exhaust have become as low as those in the ambient air. Therefore, variety of alternative measurement methods has been developed in the industry and raising many arguments comparing each technique. On the other hand, the reduction of particulate matters and nitric oxides in diesel emissions are also big issues for environmental protection. Adequate measurement techniques for particulate matters and nitrogen components have been required to develop new systems for diesel after-treatment. This paper summarizes such latest techniques for the emission measurements of advanced vehicles.
