This experimental work was performed to reveal the effect of intake air temperature on the improvement of performance and exhaust emissions in a SI engine. To achieve this, fuel consumption rate, combustion pressure, rate of heat release, and reduction of exhaust emissions were measured and compared in 4-cylinder spark ignition engine. It was founded that lower intake air temperature can lead higher combustion pressure and heat release rate due to the higher intake air flow rate, volumetric efficiency, and fuel consumption rate. At the same time, higher intake air temperature leads to the longer ignition delay time, therefore, retarded ignition of engine was observed. Lower CO and HC values were also observed as the intake air temperature increases.
