Tapped and Flanged Exhaust Connections for Small Engines

2001-07-31
CURRENT
J624_200107
This SAE Recommended Practice applies to domestic four-cycle air- and water-cooled engines having a maximum of 14.9 kW (20 hp) or less in power output and/or 0.82 L (50 in3) or less in displacement, with horizontal or vertical crankshafts. The engine shall be furnished with a minimum of either a tapped exhaust port or two tapped holes and flat port face making possible use of a threaded connector or one of the flanges shown in Figure 1. Exhaust flanges are sized to be used with mild steel or aluminized steel butt-welded tubing.

Bystander Sound Level Measurement Procedure for Small Engine Powered Equipment

2012-05-11
CURRENT
J1175_201205
This SAE Recommended Practice establishes the instrumentation and procedure to be used in measuring the bystandard sound level of engine powered equipment under 15 kW (20 bhp) typical of their normal operation. It is intended to include equipment such as lawn mowers, snow blowers, and tillers. It is not intended to include equipment designed primarily for operation on highways or within factories and buildings, or vehicles such as motorcycles, snowmobiles, and pleasure motorboats that are covered by other SAE Standards or Recommended Practices. This procedure does not cover chain saws. The SAE Recommended Practice may also be used when measuring the bystander sound level on similar equipment powered by electricity or other power sources.

TEST PROCEDURE FOR THE MEASUREMENT OF GASEOUS EXHAUST EMISSIONS FROM SMALL UTILITY ENGINES

1993-02-01
HISTORICAL
J1088_199302
This SAE Recommended Practice specifies a uniform procedure for the evaluation of gaseous exhaust emissions from small utility engines typically less than 20 kW. Details of engine test setup and exhaust gas analysis techniques are specified with the intent of providing a uniform and reproducible method of measurement. The intent has been to allow as much flexibility as possible in the physical construction of the experimental apparatus. Therefore, only those portions of the apparatus whose operation is critical to the accurate measurement of emissions levels are prescribed in detail. An engine test procedure including a test sequence is outlined such that it would cover the various applications in which small engines are used. The intent is to provide an understanding of the levels of exhaust emissions and does not imply that in a given application, an engine would operate in all the modes outlined in the test procedure.
