% REVISION HISTORY
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 06/23/98 (tm): created from a_dodg3l.m
% 07/06/98 (MC): corrected max power calc. in mass calc.
% renamed fc_init_coolant_temp to fc_coolant_init_temp
% 07/17/98 (tm): file renamed FC_SI102.M
% 07/16/98 (SS): added variable fc_fuel_type under file id section
% 07/17/98 (tm): fc_fuel_den changed from 0.737 to 0.749 and fc_fuel_lhv changed from 42.7 to 42.6
% 07/30/98 (sb): added A/F ratio and split of waste heat variables
% 10/9/98 (vh,sb,ss): added pm and removed init conditions and added new exhaust variables
% 10/13/98 (MC): added variable fc_disp under file id section
% fc_ct_trq computed according to correlation from JDMA, 5/98
% 10/13/98 (MC): updated equation for fc_ct_trq (convert from ft-lb to Nm)
% 12/17/98 ss,sb: added 12 new variables for engine thermal modelling.
% 01/25/99 (SB): modified thermal section to work with new BD, revised FC mass calc's
% 2/4/99: ss,sb changed fc_ext_sarea=0.3*(fc_max_pwr/100)^0.67 it was 0.3*(fc_max_pwr/100)
% it now takes into account that surface area increases based on mass to the 2/3 power
% 3/15/99:ss updated *_version to 2.1 from 2.0
% 7/9/99:tm cosmetic changes
% 11/03/99:ss updated version from 2.2 to 2.21
% 01/31/01: vhj added fc_cold=0, added cold map variables, added +eps to avoid dividing by zero
% 02/26/01: vhj added variable definition of fc_o2_map (used in NOx absorber emis.)
% 03/15/01: vhj,ss; fixed fc_o2_map to use fc_fuel_map_gpkwh instead of fc_fuel_map
% 7/30/01:tm added user definable mass scaling function mass=f(fc_spd_scale,fc_trq_scale,fc_base_mass,fc_acc_mass,fc_fuel_mass)
