Abstract

This study commisioned to develop cold air intake models for an internal combustion car engine that operates on a Otto Cycle and to measure the increment of performance made by the models by calculating the temperature drops. Since the performance of an internal combustion is limited, therefore a solution is needed to improve the efficiency and the performance of a car at the same time by spending less money. It is found that when the temperature of the air is lower, the density of the oxygen increases, thus allowing a better combustion of the air and fuel mixture in the combustion chamber. The study was carried out by measuring the temperature drops on four models. Two of the models were made by implementing with thermoelectric coolers, one was made so to operate without energy and last one by sharing cold air from inside the cabin of a car. At the end of the study, it was found that all models of the cold air intake were able to cause decrement on the temperature of the air. However, three of models showed increment that were believed to be at an insignificant and unnoticable range of less than 1 % increment. Only one of models showed a significant increment in the value, which is by drawing the air from the car cabin to the intake valve. The increment made by the model almost reach 3 %, which can be improved if the material of the model and the position of the model be revised in order to eliminate heat transfer at the engine bay.
