Improving Diesel Engine Performance by Air-To-Air Intercooling

Abstract

The paper studies the increase in performance of a heavy-duty turbocharged diesel engine when the intake air is cooled in an air-to-air heat exchanger, being turned into a turbocharged and inter-cooled engine. There were presented dynamometric tests, being evaluated engine performance parameters such as rated power, torque, hourly and specific consumptions, and smoke level on the speed characteristic at total load. Stress is laid on the influence of air charge thermodynamic parameters on cooler effectiveness and pressure loss.
