Cal. Code Regs. tit. 13 § 2780
These procedures apply to LSI retrofit emission control systems, which, through the use of sound principles of science and engineering, control emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) from off-road large spark-ignition (LSI) engines. These systems may include but are not limited to, closed-loop fuel control systems, fuel injection systems, and three-way catalysts. These procedures are not applicable to retrofit strategies that employ or make use of fuel additives.
The use of LSI retrofit emission control systems verified in accordance with this article may be a means of complying with other state board regulations applicable to the use of LSI engines, to the extent provided for in those regulations.
