    摘要: A method for cold start white smoke protection of a hydrocarbon after treatment device, and method of engine operation to effect the same. The method comprises a) determining the temperature of the hydrocarbon after-treatment device during cold start conditions; b) determining hydrocarbon emissions in the hydrocarbon after-treatment device; and c) modifying engine operating conditions to raise the hydrocarbon after-treatment temperature at a pre-determined rate to a temperature sufficient to permit controlled oxidation of the hydrocarbons in the hydrocarbon after treatment device.

    摘要: A method for diagnosing a turbocharger (10) includes disconnecting the compressor outlet conduit (26) so that the engine (12) is naturally aspirated and using the engine to drive the turbine (14) of the turbocharger. The compressor outlet conduit (26) has a restriction (28) to create a backpressure which is measured along with the inlet pressure, barometric pressure and ambient temperature. The flow rate is determined and compared to acceptable parameters from a map data provided by a turbocharger manufacturer to diagnose if the turbocharger is operating within the acceptable parameters.
