EPA has recently been involved in the development of transient engine and chassis cycles from the CAPE-21 survey data. The CAPE-21 survey data was gathered from eighty-eight in-use trucks; forty-four in New York City and forty-four in Los Angeles. Vehicle speed, engine rpm, engine power, engine temperature, and various traffic and road describers were recorded on tape, at approximately one second intervals. Prior to the actual generation of the cycles, the need for a unique cold start cycle (engine and/or chassis) was investigated. This report summarizes this investigation.
