2.3 MECHANICAL ENGINEERING
This research examined the practical effects of cooling the intake air, on the combustion characteristics of a modern motor vehicle operating under simulated road conditions as well as its subsequent impact on the environment. The cooling effect was achieved by taking a typical air conditioning rig as fitted to a modern motor vehicle and incorporating it into the induction system of the car. The test vehicle used was a 1993 Renault Safrane 2.0Vi standard passenger car that was modified as part of the research to facilitate the extraction of the required test information. A series of tests were conducted using ambient temperature air and cold air delivered by the air conditioning rig. The results obtained were consistent and conformed to general automotive beliefs regarding power, fuel consumption and emissions.
