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.
There currently is no industry standard for measuring and reporting fuel consumption for off road SSI engines. Fuel consumption is a critical performance factor for engines and fuel consumption gathered from non-uniform test cycles may result in inaccurate comparisons of engine to engine performance.
