Nowadays turbocharged diesel engines are prime movers of transport machines and are widely researched in order to optimise their performance. Significant percent of diesel engine's operation consists of transient operations. Transient operations, particularly acceleration, causes imbalance of fuel-air ratio, as a result of turbocharger lag in regard to fuelling. In this research two transient operations: acceleration and deceleration of CAT 3512B-HD engine are analysed. Results show a significant deviations during accelerations that causes 26% to 58% increase of specific fuel consumption during acceleration and no noticeable negative effects during deceleration.
