Summary:

Thermal Engine Encapsulation (TEE) is a technique for reducingheat loss from an engine after it has been switched off, in orderto get a warmer re-start. This practice yields benefits in terms offuel economy, emissions and wear, especially for vehicles used forshort journeys in cold weather and with engines warming upslowly.In this study, the encapsulation of a small automotive dieselengine is investigated by means of theoretical and experimentalanalyses. In particular, the influence of oil temperature on brakespecific fuel consumption and emissions is calculated. Furthermore,the thermal behavior of the engine has been simulated by alumped-capacitance model, in order to assess the correlationbetween encapsulation thickness and cool-down time.Finally, the 0-D thermal model and the 1-D engine model havebeen coupled in order to predict the influence of engine crankingtemperature on fuel consumption and pollutant emissions,considering a B-class vehicle running a short journey (15 minutes)at medium speed and load and very low external temperature(0\mDC)
