Abstract
A method for simulating at least one drive cycle of a vehicle using a non-engine based test system, the method including providing a non-engine based test system including a combustor in fluid communication with a catalytic converter from the vehicle; supplying fuel and air to said combustor at an air to fuel ratio (AFR) and under conditions effective to produce a feedstream flowpath; substantially stoichiometrically combusting at least a portion of the fuel in the feedstream flowpath under conditions effective to simulate at least one drive cycle of the vehicle and to produce a simulated drive cycle exhaust product for the vehicle, the conditions being effective to prevent substantial damage to the combustor; and, collecting and analyzing the simulated drive cycle exhaust product.
