Spark-Ignited Engine/Equipment (Less Than or Equal To 1 Liter)
LSIE ≤1 Liter regulations incorporate by reference the Small Off-Road Engine and Equipment certification and approval procedures. As a result, the evaporative certification procedures for 2011 and Later LSIE ≤1 Liter are the same as those for Small Off-Road Engines and Equipment (except Small Production Volume Tank Exemption). The following are the relevant SORE documents:
