    Exploring Diesel Engine Friction and Fuel Mass Flow Rate

    Hi, Thanks for the reply. I have attached a graph of the power against fuel mass flow rate at 1000rpm. As the engine reaches it's full load, the fuel mass flow rate starts to increase a lot more dramatically. As you can see from the graph, the last four points don't really follow the...

    Exploring Diesel Engine Friction and Fuel Mass Flow Rate

    Hi I have been plotting a Willans line, (engine power against fuel mass flow rate) and I noticed that the line is fairly linear up to about 75% and then it starts to increase a bit more dramatically. So I was wondering how does engine power at a fixed RPM effect fuel mass flow rate? Is...

    MATLAB Entering simulink 3D look-up table data from MATLAB

    I have created a contour plot in MATLAB using the following code: >> NP=40; >> [RP TP]=meshgrid(linspace(min(RPM),max(RPM),NP),linspace(min(BMEP),max(BMEP),NP)); >> BSFC_IT=griddata(RPM,BMEP,BSFC,RP,TP); >> NC=12; >> Fig1=figure; >> [CT...

    Hybrid bus simulink motor generator

    Hi, I am making a Simulink model for the drive cycle of a hybrid bus. My bus is using a gas turbine engine to power a generator which then charges the batteries. I have a motor model which I have attached a screenshot of, and I know I can use this as a generator also. I just have no idea...

    MATLAB How to control power source base on load condition in Matlab/simulink

    You could try using an 'If Block' in simulink and have your output going into an 'If action'. Then the output of these if action blocks could be represented by a number and you then merge all of the if actions to get a continuous variable. You could then link the output of the merge into the...

    MATLAB Filter command for contour plot MATLAB

    Hi all, I have made a BSFC plot in MATLAB with engine data tested on an eddie current dyno, The code I used for it is: >> NP=40; >> [RP TP]=meshgrid(linspace(min(RPM),max(RPM),NP),linspace(min(Torque),max(Torqu e),NP)); >> BSFC_IT=griddata(RPM,Torque,BSFC,RP,TP); >> NC=12; >>...
