Investigating and Comparison of Emission and Fuel Consumption Behavior of Diesel Vehicles under Various Elevations Using Portable, M.Sc. Thesis Sharif University of Technology ; Hosseini, Vahid (Supervisor)
Abstract
As elevation increase, environmental impacts will change, and this will affect on vehicle performance. The pressure drop and consequently the drop in air density at high altitude affect the volumetric efficiency of the engine. This exacerbates engine combustion, since the engine displacement volume is constant, with the drop in air density, the intake air mass flow rate decreases. In this situation, the engine does not have enough air to burn the fuel, and as a result the engine ignition will getting into the defect. ECU only changes the amount of injecting fuel and has no control on the entering air flow to the engine. In such circumstances, emissions from the vehicle are expected to...
