Development of the SAURER D4KT-B Diesel Engine

Information on objectives and development achievements of the newly introduced SAURER DK-B engine family for heavy duty truck applications is presented. In particular comparative results obtained with different supercharging methods on the same basis engine and data about transient response and altitude operation are given.

The present D4KT-B engine, being the most advanced SAURER power plant, is characterized by a constant power output between 1800 rpm and the rated speed of 2000 rpm and, due to the application of combined turbocharging by a high maximum torque at low engine speed.
