Optimizing Combustion Processes in Diesel Engines Using Variable Compression Ratio Technology

Abstract

Diesel engines are essential in the transportation and industrial sectors due to their notable efficiency and ability to deliver power. Optimizing combustion processes in diesel engines improves performance, increases fuel efficiency, and minimizes pollutants. Through a comprehensive analysis of existing research studies, experimental data, and computational simulations, this review aims to provide insights into the effectiveness of variable compression ratio (VCR) technology in achieving optimized combustion processes in diesel engines. It explores the fundamental principles (fuel efficiency, combustion stability, emission measurement, dynamic response, and heat release) of optimizing combustion in diesel engines, the operational advantages of VCR technology, and the possible improvements in engine economy. The review concludes that adjusting the CR based on operating conditions can assist in fine-tuning combustion parameters to achieve more complete and efficient fuel combustion, resulting in higher thermal efficiency and reduced fuel consumption.
