Procedure for Mapping Fuel Consumption for small spark ignited engines

2017-03-22
WIP
J3139
The purpose of this SAE Standard is to provide a standardized test procedure for measuring the fuel consumption of spark ignited engines in the range of 225-999cc used in the consumer and commercial turf industry. The load points and associated fuel consumption rates will be measured as the engine operates on the engine speed governor, reflecting how the user will operate the equipment. The fuel consumption calculated in gallons of useage per hour will be derived from a specified engine speed and load map to be communicated universally to end users.

Hydrocarbon Adsorber Test Procedure

2010-09-01
WIP
J2952
This SAE Recommended Practice describes several procedures to test and measure the performance of a Hydrocarbon Adsorber device located in a vehicle air induction system and attempts to simulate various loading and purging cycles it could experience. The Hydrocarbon Adsorber device is used to adsorb the small amount of gasoline that is volatized in the air induction manifold after the vehicle engine is turned off. This gasoline vapor can travel through the air induction system and escape to the atmosphere, impacting the total allowable vehicle evaporative emissions level set by the EPA and California ARB. When the vehicle is restarted, the Hydrocarbon Adsorber device is purged of hydrocarbons with the fresh air flow and is designed to perform as life of the vehicle emission device as set by the EPA.
