Section 2781 - Definitions(a) The definitions in Section 1900(b), Chapter 1, Title 13 of the California Code of Regulations are incorporated by reference herein. The following definitions shall govern the provisions of this chapter: (1) "Applicant" means the entity that has applied for or has been granted verification under this Procedure(2) "Average" means the arithmetic mean.(3) "Baseline" means: (i) for uncontrolled engines, the emission levels from the engine as tested without the LSI retrofit emission control system implemented using the test cycle specified in this verification procedure; and(ii) for certified engines, the emission standards to which the engine was certified.(4) "Certified engine" means an engine manufactured in compliance with ARB or EPA emission standards.(5) "Durability" means the ability of the applicant's LSI retrofit emission control system to maintain a level of emissions at or below its verification emission level and maintain its physical integrity over the durability periods specified in these regulations. The minimum durability demonstration periods contained herein are not necessarily meant to represent the entire useful life of the LSI retrofit emission control system in actual service.(6) "Emergency Engine Repair" means repair conducted outside of normal scheduled maintenance that is required for the safe operation of the equipment.(7) "Emission Control Group" means a set of LSI engines and applications determined by parameters that affect the performance of a particular LSI retrofit emission control system. The exact parameters depend on the nature of the LSI retrofit emission control system and may include, but are not limited to, baseline or certification levels of engine emissions, combustion cycle, displacement, aspiration, horsepower rating, duty cycle, exhaust temperature profile, and fuel composition. An applicant could specify an emission control group to be comprised of engines from several different engine families, applications and equipment manufacturers. Verification of an LSI retrofit emission control system and the extension of existing verifications is done on the basis of emission control groups.(8) "Executive Officer" means the Executive Officer of the Air Resources Board or the Executive Officer's designee.(9) "Executive Order" means the document signed by the Executive Officer that specifies the verification level or percentage reduction of an LSI retrofit emission control system for an emission control group and includes any enforceable conditions and requirements necessary to support the designated verification.(10) "Hot Start" means the start of an engine within four hours after the engine is last turned off.(11) "LSI retrofit emission control system" means any device or system employed with an in-use off-road LSI-engine vehicle or piece of equipment that is intended to reduce emissions. Examples of LSI retrofit emission control systems include, but are not limited to, closed-loop fuel control system, fuel injection system, three-way catalysts, and combinations of the above.(12) "LSI Retrofit Emission Control Group Name." See Section 2786(c)(2).(13) "Off-Road Large Spark-Ignition Engine" or "LSI Engine" means any spark ignition engine that produces a gross power of greater than 19 kilowatts (25 horsepower) or is designed (e.g., through fueling, engine calibrations, valve timing, engine speed modifications, etc.) to produce greater than 19 kW ( >25 hp), and is used in an off-road vehicle or equipment that is not excluded below. If an engine family has models at or below 19 kW (25 hp) and models above 19 kW (25 hp), only the models above 19 kW (25 hp) would be considered LSI engines. A spark ignition engine's operating characteristics are significantly similar to the theoretical Otto combustion cycle with the engine's primary means of controlling power output being to limit the amount of air and fuel that is throttled into the combustion chamber of the engine. LSI engines are designed for powering equipment applications including, but not limited to, forklift trucks, sweepers, generators, and industrial equipment and other miscellaneous applications. Specifically excluded from this category are: i) engines operated on or in any device used exclusively upon stationary rails or tracks;ii) engines used to propel marine vessels;iii) internal combustion engines attached to a foundation at a location for at least 12 months;iv) off-road recreational vehicles and snowmobiles; andv) stationary or transportable gas turbines for power generation.(14) "Off-Road Vehicle" or "Off-Road Equipment" means any non-stationary device, powered by an internal combustion engine or motor, used primarily off the highways to propel, move, or draw persons or property including any device propelled, moved, or drawn exclusively by human power. Examples include, but are not limited to, marine vessels, construction/farm equipment, industrial equipment, locomotives, small off-road engines, off-road motorcycles, and off-highway recreational vehicles.(15) "Otto Cycle Engine" means a type of engine with operating characteristics significantly similar to the theoretical Otto combustion cycle. The primary means of controlling power output in an Otto cycle engine is by limiting the amount of air and fuel that can enter the combustion chambers of the engine. As an example, gasoline-fueled and LPG engines are Otto cycle engines.(16) "Revoke" means to cancel the verification status of an LSI retrofit emission control system. If an LSI retrofit emission control system's verification status is revoked by the Executive Officer, the applicant must immediately cease and desist selling the LSI retrofit emission control system to end-users.(17) "Verification" means that after the data submitted has been thoroughly evaluated and an engineering judgment has determined that an LSI Retrofit Emission Control System for installation on in-use equipment will meet the requirements of this procedure, an Executive Order is issued. This ensures the emissions reductions achieved by the control strategy are real and durable and production units in the field achieve reductions consistent with the verification procedure.Cal.
