Simulation of the Transient Performance of a Turbocharged Diesel Engine Featuring a Two-Point Air Injection Transient Assist System

摘要

Growing global concern pertaining to climate change has meant that engine development has become more focused on engine emissions. A method of reducing the emissions of an internal combustion (IC) engine is to use smaller engines but recover power lost due to reduction in size by using a turbocharger or supercharger. Turbocharged vehicles are commonly used but they exhibit a weak point of poor performance under transient running conditions. The phenomenon, known as 'Turbo-lag,' is most noticeable when a sudden load change is applied at lower engine speeds combined with rapid acceleration.
