Unless specifically defined in the TCAA or in the rules of the commission,
the terms used by the commission have the meanings commonly ascribed to them
in the field of air pollution control. In addition to the terms which are
defined by the TCAA, the following words and terms, when used in this division,
shall have the following meanings, unless the context clearly indicates otherwise.
(1) The definitions found in Title 13, California Code of Regulations,
Chapter 9, §2431, concerning Definitions, as effective on November 18,
1999, are hereby incorporated by reference.
(2) Non-road, large spark-ignition (LSI) engine - Any
engine that produces a gross horsepower (hp) of 25 hp or greater, or is designed
(e.g. through fueling, engine calibrations, valve timing, engine speed modifications,
etc.) to produce 25 hp or greater. For engine families which have models at
or greater than 25 hp, as well as models below 25 hp, only the models at or
above 25 hp are considered LSI engines. The engine operating characteristics
are significantly similar to the theoretical Otto combustion cycle, with the
primary means of controlling power output being the limit on the amount of
air that is throttled into the combustion chamber of the engine. LSI engines
or alternate fuel-powered LSI internal combustion engines are designed for,
but not limited to, powering forklift trucks, sweepers, generators, industrial
equipment, and other miscellaneous applications.
(3) New non-road, large spark-ignition (LSI) engine -
Non-road, LSI model year 2004 and subsequent engines, and all equipment and
vehicles that use such an engine.
