Investigation Into The Correlation Between Intake Air Temperature And Fuel Consumption In Chevrolet Cobalt Vehicles Equipped With A 1.5-Litre B15d2 Engine Under Winter Operational Conditions

Abstract

This research is specifically aimed at determining and evaluating the precise correlation that exists between the intake air temperature entering the engine and the subsequent fuel consumption rates of Chevrolet Cobalt passenger cars during winter operational periods. Over the course of this investigation, the multi-faceted effects of ambient environmental temperatures, along with the thermal regime of the internal combustion engine, on overall fuel economy were systematically examined utilizing comprehensive analytical methods and mathematical modelling techniques. The empirical and theoretical outcomes obtained demonstrate that under low-temperature conditions, fuel consumption increases significantly and substantially, which is primarily driven by the extended engine warm-up durations required and the inherently increased density of the cold intake air.
