    In the case of the example, for injected mass of fuel, how do you relate this to engine load? I want to run the example at a load of 20/60/120Nm, currently the injected fuel is set to 45 mg/cycle, I was just having difficulty relating the two?

    In steady operation, Diesel engine running conditions are controlled in OpenWAM by giving engine speed and injected fuel. Engine torque (load) is an output from the simulation.
    As far as I know, future OpenWAM versions will include a sensor to the engine torque and an actuator to the injected fuel. Therefore, we will be able to perform simulations by giving engine speed and torque.
    At the time being, you will have to carry out several simulations and tune the fuel quantity in order to get the engine torque you desire (20, 60 & 120 Nm).

    Regards,

    Héctor

    PS: Engine torque value can be reached at MED.DAT file. Check the value in the last simulated cycle (i.e. the last row).

    In terms of engine load, for example 20Nm, do I modify the engine model so that the effective torque is 20Nm or so that the net torque is 20Nm. Which torque is the “load” torque?

    The torque that you obtain at the gear box input is the effective torque.
