Pressure Sensor Indicates Engine Cylinder Load- Literature Available

The BMEP balance Model 300A manufactured by General Thermodynamics Corporation is used in the process of equalizing cylinder load in large, multicylinder spark-ignited and diesel engines with individual fuel adjustment. It is designed to fit the standard indicator valve and is easily connected. When the incicator valve is opened, the pressure gauge comes to a reading indicative of cylinder load. Keeping the engine load constant, readings are taken for each cylinder, then fuel adjustments are made either lip or down until all c y l i n d e r s deliver the same pressure reading. The power generated in each cylinder is now equal.

The BMEP balancer is a pneumatic clamping system that yields the mean value of the pressure inside the cylinder for the entire cycle. Although peak firing pressures may be well in excess of 1,000 psi, the mean pressure for the cycle is usually not more than 150 psi. This value is dependent upon engine design.

The balancer is constructed of stainless steel throughout, features metal-to-metal seals in place of gaskets, and has no moving parts, making maintenance virtually unnecessary.
