This document summarizes the process followed to utilize EPA's laboratory engine and chassis dynamometer test data to generate a full engine fuel consumption map for the Chevrolet 4.3L EcoTec3 LV3 V6 engine with cylinder deactivation found in the 2014 Chevrolet Silverado tested on LEV III fuel. The generated full engine map defines the complete operating boundaries of the engine which are needed for ALPHA modeling including idle, WOT, minimum torque, and maximum speed.

Engine Build for Simulation in ALPHA
Construct the ALPHA engine, combining all of the above inputs. Fit the fueling data onto a grid for simple interpolation and establish points that represent the maximum and minimum engine torque versus speed. Confirm the quality of fit between the input data and the resulting engine description by examining the resulting plots.
engine = REVS_build_engine(engine, {test_data, trans_test_data, idle_data, est_data} ,'WOT',WOT_data, 'deac',{deac_test_data}, 'plot_bsfc','plot_efficiency');
Idle Fuel Verification
Confirm appropriate fuel consumption near idle conditions. The following conditions represent idle observed during testing with the engine coupled to the transmission. However, in general, idle speeds and fueling depend on the drivetrain the engine is coupled to and may change depending on the application.
% Idle @ 560 RPM in drive measured fuel rate ~0.245 g/sec

Fuel Map Linearity
Confirm expected trends in output fuel map, specifically in regions where test data is unavailable.

Model Calibration Options
Calibrate additional properties of the ALPHA engine model which can be set to match observed behaviors during the validation process.
Note: Default values are used unless properties are specified below, which are derived from the composite set of EPA testing and model validation activities.
Accelerator Pedal Mapping
Set pedal mapping type to map engine power to increase linearly with accelerator pedal position.
engine.pedal_map_type = enum_engine_pedal_map_type.max_engine_power;
Deceleration Fuel Cut-Off (DFCO) Transition Adjustment
Set the fueling adjustment related to DFCO events based on the behavior observed during chassis dynamometer testing. The image below shows a sample return to fueling after DFCO, and the additional fuel used beyond the steady state map. This and other test data was used to calibrate the values below.
engine.DFCO_min_duration_secs = 2.0; % DFCO defueled duration before triggering additional fueling engine.DFCO_refuel_multiplier = [1.0, 2.0, 1.0]; % DFCO refuel multiplier profile engine.DFCO_refuel_multiplier_time_secs = [0.0, 0.1, 2.0]; % DFCO refuel multiplier profile time [sec]
Cylinder Deactivation (CDA) Transition Adjustment
Set the fueling adjustment related to CDA events based on observed transitions into and out of CDA. The image below shows typical transitions into and out of CDA. This and other observed transitions are approximated by the calibration below.
engine.deac_transition_on_duration_secs = 1.0; % Cylinder deactivation turn on fuel map blending engine.deac_transition_off_duration_secs = 0.1; % Cylinder deactivation turn off fuel map blending engine.deac_transition_off_fuel_multiplier = [1.8 1.0]; % Cylinder deactivation turn off adjustment fuel multiplier profile engine.deac_transition_off_fuel_multiplier_time_secs = [0.0 2.0]; % Cylinder deactivation turn off adjustment fuel multiplier profile time [sec]
