Abstract
The torque produced by an internal combustion engine is measured by algebraically combining averaged cylinder pressure with inlet manifold pressure, and manifesting the sum thereof. By multiplying the summed result by a factor representing engine speed, a direct measure of engine horsepower is obtained. The result may be displayed by an indicator or the like to provide an indication useful in operating or adjusting the engine.
