2013 Chevrolet 2.5L Ecotec LCV Engine Reg E10 Fuel - ALPHA Generation Process

This document summarizes the process which utilized laboratory engine dynamometer and chassis dynamometer test data collected by FEV and EPA to generate a full engine fuel consumption map which can be used by EPA's ALPHA vehicle simulation tool. The generated map defines the complete operating boundaries of the engine which are needed for ALPHA modeling including idle, WOT, minimum torque, and maximum speed.

  class_REVS_fuel with properties:

                        id: 'FEV Malibu'

    energy_density_BTUplbm: 17647
          specific_gravity: 0.75773

Idle Speed

Set idle speed using EPA chassis dynamometer testing. (EPA published report pending)

engine.idle_speed_radps =  class_REVS_dynamic_lookup;
engine.idle_speed_radps.axis_1.signal = 'veh_spd_mps';
engine.idle_speed_radps.axis_1.breakpoints = [0,1,5,100];
engine.idle_speed_radps.table = [650,750,1000,1000] * convert.rpm2radps;

Engine Build for Simulation in ALPHA

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, {test_data, idle_data} ,'WOT',WOT_data, 'CT', CT_data, 'plot_bsfc','plot_efficiency');

Idle Fuel Verification

Confirm appropriate fuel consumption near idle conditions. The following conditions represent idle with the transmission in drive. 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 depenging on the application.

Idle @ 650 RPM in drive measured fuel rate ~0.21 g/sec

engine.interp_fuel_gps( 650 * convert.rpm2radps, 28);
      0.22021

Fuel Map Linearity

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

REVS_plot_engine_fuel_linearity(engine)

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

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

Use the default adjustment factors during the simulation, since there is no transient fueling data available.

File Description

Generate and write the created ALPHA engine definition into a file for later simulation.
