Performance, Design and Operational Parameters of Variable Compression Ratio Diesel Engine

Abstract

The development and implementation of Variable Compression Ratio technology in diesel engines has garnered significant attention due to its potential to revolutionize engine performance and efficiency. Understanding how the design of Variable Compression Ratio diesel engines influences performance parameters, such as brake thermal efficiency, brake specific fuel consumption, brake power, and exhaust gas temperature, could prove vital for engineers and designers, as it directly contributes to optimizing performance. Several studies have reported the key design considerations and engineering challenges associated with Variable Compression Ratio diesel engines, along with their impact on overall performance and durability. However, this work critically discusses design factors, parameters, and governing equations and evaluates how they influence the operational parameters. Through a systematic review of existing literature and technical insights, this work aims to clarify the potential and limitations of  Variable Compression Ratio technology in diesel engines, offering valuable guidance for future research and development in this crucial field of automotive engineering.
