Dynamometer-idle for automatic transmission code heavy-duty engines means the manufacturer's recommended engine speed without a transmission that simulates the recommended engine speed with a transmission and with the transmission in neutral.
Engine code means a unique combination, within an engine-system combination, of displacement, carburetor (or fuel injection) calibration, choke calibration, distributor calibration, auxiliary emission control devices, and other engine and emission control system components specified by the Administrator.
Engine family means the basic classification unit of a manufacturer's product line used for the purpose of test fleet selection and determined in accordance with § 86.082-24.
Engine family group means a combination of engine families for the purpose of determining a minimum deterioration factor under the Alternative Durability Program.
Engine-system combination means an engine family-exhaust emission control system combination.
EPA Enforcement Officer means any officer or employee of the Environmental Protection Agency so designated in writing by the Administrator (or by his designee).
Evaporative emission code means a unique combination, in an evaporative emission family-evaporative emission control system combination, of purge system calibrations, fuel tank and carburetor bowl vent calibrations and other fuel system and evaporative emission control system components and calibrations specified by the Administrator.
Evaporative vehicle configuration means a unique combination of basic engine, engine code, body type, and evaporative emission code.
Fuel evaporative emissions means vaporized fuel emitted into the atmosphere from the fuel system of a motor vehicle.
High-altitude conditions means a test altitude of 1,620 meters (5,315 feet), plus or minus 100 meters (328 feet), or equivalent observed barometric test conditions of 83.3 ±1 kilopascals.
High-altitude reference point means an elevation of 1,620 meters (5,315 feet) plus or minus 100 meters (328 feet), or equivalent observed barometric test conditions of 83.3 kPa (24.2 inches Hg), plus or minus 1 kPa (0.30 Hg).
Hot-soak losses means evaporative emissions after termination of engine operation.
Inertia weight class means the class, which is a group of test weights, into which a vehicle is grouped based on its loaded vehicle weight in accordance with the provisions of part 86.
Intermediate speed means peak torque speed if peak torque speed occurs between 60 and 75 percent of rated speed. If the peak torque speed is less than 60 percent of rated speed, intermediate speed means 60 percent of rated speed. If the peak torque speed is greater than 75 percent of rated speed, intermediate speed means 75 percent of rated speed.
Loaded vehicle weight means the vehicle curb weight plus 300 pounds.
Malfunction means not operating according to specifications (e.g., those specifications listed in the application for certification).
Maximum rated horsepower means the maximum brake horsepower output of an engine as stated by the manufacturer in his sales and service literature and his application for certification under § 86.082-21.
Maximum rated torque means the maximum torque produced by an engine as stated by the manufacturer in his sales and service literature and his application for certification under § 86.082-21.
Military engine means any engine manufactured solely for the Department of Defense to meet military specifications.
Model means a specific combination of car line, body style, and drivetrain configuration.
Model year means the manufacturer's annual production period (as determined by the Administrator) which includes January 1 of such calendar year: Provided, That if the manufacturer has no annual production period, the term model year shall mean the calendar year.
Option means any available equipment or feature not standard equipment on a model.
Peak torque speed means the speed at which an engine develops maximum torque.
Percent load means the fraction of the maximum available torque at a specified engine speed.
Rated speed means the speed at which the manufacturer specifies the maximum rated horsepower of an engine.
Round has the meaning given in 40 CFR 1065.1001, unless otherwise specified.
Running loss means fuel evaporative emissions resulting from an average trip in an urban area or the simulation of such a trip.
Scheduled maintenance means any adjustment, repair, removal, disassembly, cleaning, or replacement of vehicle components or systems which is performed on a periodic basis to prevent part failure or vehicle (if the engine were installed in a vehicle) malfunction.
Smoke means the matter in the exhaust emission which obscures the transmission of light.
System includes any motor vehicle engine modification which controls or causes the reduction of substances emitted from motor vehicles.
Tank fuel volume means the volume of fuel in the fuel tank(s), which is determined by taking the manufacturer's nominal fuel tank(s) capacity and multiplying by 0.40, the result being rounded using ASTM E 29-67 to the nearest tenth of a U.S. gallon.
Test weight means the weight, within an inertia weight class, which is used in the dynamometer testing of a vehicle, and which is based on its loaded vehicle weight in accordance with the provisions of part 86.
Throttle means the mechanical linkage which either directly or indirectly controls the fuel flow to the engine.
Transmission class means the basic type of transmission, e.g., manual, automatic, semiautomatic.
Transmission configuration means a unique combination, within a transmission class, of the number of the forward gears and, if applicable, overdrive. The Administrator may further subdivide a transmission configuration (based on such criteria as gear ratios, torque convertor multiplication ratio, stall speed and shift calibration, etc.), if he determines that significant fuel economy or exhaust emission differences exist within that transmission configuration.
Unscheduled maintenance means any adjustment, repair, removal, disassembly, cleaning, or replacement of vehicle components or systems which is performed to correct a part failure or vehicle (if the engine were installed in a vehicle) malfunction.
(1) For light-duty vehicles and light-duty trucks a period of use of 5 years or 50,000 miles, whichever first occurs.
(2) For gasoline-fueled heavy-duty engines a period of use of 5 years or 50,000 miles of vehicle operation or 1,500 hours of engine operation (or an equivalent period of 1,500 hours of dynamometer operation), whichever first occurs.
