The Effect of Exhaust Throttling on the Diesel Engine Operation Characteristics and Thermal Loading

In SAE paper No. 860293, the first conclusions from application of the technique of forced regeneration of the ceramic trap by exhaust throttling of the diesel engine had been presented.

The presentation is integrated in this paper, by a thorough interpretation and modelling of the effect of exhaust throttling on the diesel engine operation characteristics and thermal loading, as well as a discussion of the possibility and particularities of application to different types of engines.

Behavior of the exhaust throttled 4-stroke diesel engine is exhaustively analyzed by use of computer simulation. Computer models are also used to study the effect of exhaust throttling on the diesel engine thermal loading.

The validity of the results is tested by a large number of measurements conducted in the LAT the last five years.
