Week-4 Challenge WOT Condition Part-2

1answer :

1.Mapped model uses a steady state look up tables to characterize engine performance.The table contains overall engine characteristics including actual torque,fuel flow rate and exhaust emission.where as dynamic model decomposes engine behaviour into engine characteristics that are separated into lower level components.

2.Mapped model is used if engine data is available from a dynamometer or a design tool where as dynamic model is used if component level data is available and to analyze impact of individual engine components on overall performance.

3.in order to change model type we have to go to car model then to engine plant model .in engine model there will be two types of motor models , mapped and dynamic motor models.we have to choose one among them.

2 answer :

1.power coming from battery is in kw. it is converted into kwh by dividing with 3600.

2.one us gasoline is equivalent to 33.7kwh. so battery energy is converted into gasolin by dividing with 33.7.

3.velocity also integated with time and distance in meters calculated.again distance in meters converted into miles by multiplying with factor 0.000621371.

4.finally distances in miles is divided with number of equivalent gasoline.

3 answer ;

1. changed temp to 290 Fahrenhiet and grade to 30 degrees in HEV model

2.set WOT starting time to 5 seconds and decelation starting time at 20 seconds.run the simulation for 30 seconds.

3. motortorque is positive .but soc of battery soc is increasing since it is getting charging by generator

4 answer :
