Exploring Noise and Vibration Challenges in Variable Compression Ratio Diesel Engines: Impact, Factors, And Mitigation Strategies

Abstract

With diesel engines maintaining their significance across various sectors, there is a critical necessity to recognize and address noise and vibration concerns. This contribution explores the sources of combustion noise and vibration, particularly in variable compression ratio (VCR) diesel engines. It evaluates the impact of these factors on engine performance and overall comfort. Additionally, the study discusses advancements in reducing noise and vibrations through design enhancements and noise control strategies. The results show that heat release rate (HRR), biodiesel blends, and VCR technology strongly influence the noise and vibration characteristics of VCR diesel engines. Future research directions to optimize engine performance, reduce vibrations and noise, and enhance comfort are also highlighted in this work.
