Catalytic Converter Exhaust System Temperature Tests.

摘要

In June 1975,the Forest Service Equipment Development Center at San Dimas,Calif.,conducted tests to determine exhaust system temperatures on late-model vehicles. Test results showed that for normal vehicle operation,only small temperature differences occurred at any point on the exhaust system between those vehicles equipped with catalytic converters and those vehicles without catalytic converters. Both kinds of exhaust systems develop temperatures higher than those necessary to ignite ground cover. However,unless certain engine malfunctions occur,peak temperatures of converter-equipped vehicles are not appreciably higher than peak temperatures of other vehicles.
