BMEP Balancer Used To Increase Fuel Efficiency In Diesels

The power an engine develops is dependent on the pressure developed in its cylinder or cylinders. The General Thermodynamics Corporation, Plymouth, Mass., uses this pressure to sense the power developed in various types of engines. Its initial application was in an aircraft engine to give a continuous reading of developed power when driving a constant speed propeller.

This is equivalent to driving a variable-pitch propeller on a ship, whereby engine power can be varied widely at any given engine speed.

For shipboard use to date, this concept is applied mostly in the form of the BMEP Balancer, Model 300-A, to equalize the power distribution among the cylinders of an engine. With the balancer, it is said to be possible to make a fuel adjustment on a cylinder, increasing or decreasing the power developed, while watching the instrument reading move to the desired value.

This would optimize fuel consumption and remove the danger of overloading a cylinder or cylinders, as well as bearings, and results in a quieter, smoother-running engine.

The actual power being developed by a running engine can be read by referring the balancer reading to a calibration chart.

The balancer attaches to a standard indicator valve and continuously senses combustion chamber pressure. There is no need for external excitation, and it is direct reading.
