Project 2
AIM: Design and Develop a simulink model to understand Energy analysis of EVs on different driving cycles
DRIVING CYCLE:
A driving cycle is a series of data points representing the speed of a vehicle versus time. Driving cycles are produced by different countries and organizations to assess the performance of vehicles in various ways, as for instance fuel consumption, electric vehicle autonomy and polluting emissions
How to build driving cycle:
start the vehicle and let it idle for two to three minutes in park or neutral. while it is idling, turn on the head lights, heater/defroster, and rear defroster for a three to five minute warm-up phase. let the idle speed settle down to near the normal speed
SIMULINK MODEL:
Wide open throttle or wide-open throttle (WOT), also called full throttle, is the fully opened state of a throttle on an engine IC engine or steam engine The term also, by extension, usually refers to the maximum-speed state of running the engine, as the normal result of a fully opened throttle plate/butterfly valve In an internal combustion engine, this state entails the maximum intake of air and fuel that occurs when the throttle plates inside the carburetor or throttle body are "wide open" (fully opened up), providing the least resistance to the incoming air.
In the case of an automobile, WOT is when the accelerator is depressed fully, sometimes referred to as "flooring it" (because automotive throttle controls are usually a pedal, so full throttle is selected by pressing the pedal to the floor, or as near as it will go). A throttle on a steam engine controls how much steam is sent to the cylinders from the boiler.
In the case of a diesel engine, which does not have a throttle valve, WOT is the point at which the maximum amount of fuel is being injected relative to the amount of air pumped by the engine, generally in order to bring the fuel-air mixture up to the stoichiometric point. If any more fuel were to be injected then black smoke would result. (Regardless of the non-literal nature of the term when applied to diesel contexts, it is nonetheless figuratively common and well understood.)
At wide open throttle, manifold veccume decreases. The higher manifold pressure in turn allows more air to enter the combustion cylinders, and thus additional fuel is required to balance the combustion reaction. (Carburetors and fuel injection systems are arranged so as to provide the correct air fuel ratio as conditions dynamically shift.) The additional air and fuel reacting together produce more power.
