Development of mathematical model to calculate fuel consumption of Essay

Development of mathematical model to calculate fuel consumption of passenger cars - Essay Example The NEDC was simulated under laboratory conditions, and driving parameters together with the fuel consumption were measured. A few driving phases were identified so that any drive cycle may be composed by these phases; and mathematical relationships have been fitted on measured data for each of the phases. The world population is 6.5 billion at the moment and rising. Climate change has caused widespread greenhouse effects like global warming, higher acid levels in oceans and reduced ice cover at the poles (Harrabin, 2013). The major causes of greenhouse effect are the by-products of industrialization, and especially carbon dioxide (Samimi & Zarinabadi, 2011). The level of carbon dioxide, the main constituent of emission by vehicles, is linked to consumption of fuel by the vehicle. Due to this there is need to regulate the amount of greenhouse gases that are emitted into the atmosphere and this is effective by fuel economy. The fuel economy (FE) of any vehicle can be calculated as a r atio of distance travelled per unit volume of fuel consumed or as the ratio of fuel consumption per distance travelled (GFEI, 2013). Fuel economy standards can be of various forms such as litres of fuel consumed per hundred kilometres of distance travelled or distance travelled per unit volume of vehicle fuel (An, et al., 2011, p. 4). The regulations pertaining to fuel economy followed by the four largest automobile markets, namely, the US, the EU, Japan and China differ significantly from each other leading to a lack of global standards on the issue.
