This document summarizes the process which utilizes EPA's laboratory engine and chassis dynamometer test data to generate a full engine fuel consumption map for the Mazda Skyactiv turbocharged 2.5L engine from the 2016 Mazda CX-9 tested on Tier 2 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.

Idle Speed
Set estimated idle speed using preliminary EPA chassis dynamometer test data for the 2017 Mazda CX-9; EPA published report pending.
engine.idle_speed_radps = 545 * convert.rpm2radps ;
Build Fuel Map
Construct simulation input for the 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, {ss_test_data, hl_test_data, ls_test_data}, 'WOT',wot_data,'plot_bsfc','plot_efficiency');
Idle Fuel Verification
Confirm appropriate fuel consumption near idle conditions. The following conditions represent idle observed during chassis testing, with engine torque estimated from CAN data and estimates of accessory load. The speeds and fuel flow agree with measurements recorded on this engine. However, in general, idle speeds and fueling depend on the drivetrain the engine is coupled to and may change depending on the application.
% Idle @ 555 RPM in drive measured fuel rate ~0.148 g/sec
engine.interp_fuel_gps( 545 * convert.rpm2radps, 4.3);
0.14902
Fuel Map Linearity
Confirm expected trends in output fuel map, specifically in regions where data is unavailable.
REVS_plot_engine_fuel_linearity(engine);
Model Calibration Options
Calibrate additional properties of the REVS 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 Map
Apply default pedal mapping for passenger cars, which will linearly increase engine power with accelerator pedal position.
engine.pedal_map_type = enum_engine_pedal_map_type.max_engine_power;
Transient Fueling Adjustments
Utilize the default adjustment factors during the simulation, since there is no transient fueling data available.
File Description
Generate and write the created REVS engine definition into a file for later simulation.
