Abstract	Currently, turbocharged diesel engines are prime movers of transport machines and are widely researched in order to optimize 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 fueling. In this research two transient operations: acceleration and deceleration of CAT 3512B-HD engine are analyzed. 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.
