Intake Boosting Techniques in Internal Combustion Engines to Increase Engine Performance

The consistently expanding demand for transport is supported by both spark and compression ignition engines. Due to globalization and rapidly expanding economies, the necessity for transport energy is enormous and constantly expanding across the world. IC engines till date prove to be the best source of powering an automobile. Even though they have been in use for many decades, there is always scope for improvement in technologies related to it. IC engines waste a huge amount of fuel energy via exhausts. Technologies like turbo-compounding prove to be useful to reduce fuel consumption and CO₂ emissions. Other modifications made to the design of intake manifold also result in changes to torque and horsepower. There are not many fully developed elective choices that may replace the internal combustion engines as they are in developing stages. As of 2020, 99.8% of the transportation worldwide is powered by IC engines and 95% of the energy comes from petroleum-based fuels. The researchers and engineers have to develop technologies to enhance the power output of the IC engines in order to fulfill the needs. This paper reviews enhancement of the IC engine by various intake boosting techniques in terms of better performance, progressive combustion and improved emissions while discussing future trends.
