calculate_optimal_efficiency

calculate_optimal_efficiency(co2_params_calibrated, mean_piston_speeds)

Calculates the optimal efficiency [-] and t.

Parameters:

• co2_params_calibrated (lmfit.Parameters) –

  CO2 emission model parameters (a2, b2, a, b, c, l, l2, t, trg).

  The missing parameters are set equal to zero.

• mean_piston_speeds (numpy.array) – Mean piston speed vector [m/s].

Returns:

Optimal efficiency and the respective parameters:

• mean_piston_speeds [m/s],
• engine_bmep [bar],
• efficiency [-].

Return type:

dict[str | tuple]
