(28) Hydrocarbon is any organic compound consisting predominantly of carbon and hydrogen.
(29) Idle speed means the unloaded engine speed of a motor vehicle when the accelerator pedal is fully released. In a vehicle equipped with an automatic transmission, this is with the drive selector in neutral or park. In a vehicle equipped with a manual transmission, this is with the gear selector in neutral and the clutch fully engaged. In all vehicles, the engine operated accessories shall be turned off.
(30) Internal combustion engine is any engine in which the combustion of gaseous, liquid or pulverized solid fuel takes place within one or more cylinders, or any engine with one or more combustion chambers.
(31) Light-duty motor vehicle is any motor vehicle having a combined manufacturer vehicle and maximum load rating (GVWR) to be carried thereon of 10,500 pounds (4,773 kilograms) or less.
(32) Malfunction Indicator Light (MIL) is known as the Check Engine light. The Malfunction Indicator Light is illuminated on the dashboard when conditions exist likely to result in emissions exceeding FTP standards by 1.5 time or worse. Alternatives include "Service Engine Soon," as well as an unlabeled icon of an engine.
(33) Manufacturers Idle-speed Specification is the engine idle speed specified for a particular motor vehicle as printed on the engine compartment emissions system data plate or in the owners manual.
(34) Model Year means the annual production period of new motor vehicles or new motor vehicle engines designated by the calendar year in which such production ends.
