Abstract

The cooling system of the charged intake air is essential for improving the engine performance. In this paper, a new
air-to-liquid cooling system (super chiller intercooler system) was designed and theoretically validated. In this
cooling system, refrigerant was used as a cooling agent for the intake air aiming to enhance the engine output
power, reduce fuel consumption and exhaust emissions. The methodology of this study was segregated into two
phases which are the design phase and the simulation phase of the proposed intercooler and used engine. The
SolidWorks software was used to design a multidimensional intercooler model. A CFD simulation was performed
using ANSYS Fluent code for the designed models of the intercooler and used engine. The experimental work is to
investigate the intercooler performance in terms of the engine performance, fuel consumption and exhaust emissions.
The theoretical calculations are carried out by adopting the heat transfer equations to verify with the simulation
results. The results show that the difference between the theoretical and simulation for the intercooler, engine and
exhaust emissions are below 10%, 25% and 13% respectively. Therefore, the results for this study are acceptable
and reasonable. The new intercooler design has 60% improved cooling charged air which is accomplished the
objective of this study by improving the cooling system.
