Abstract
Engines were invented two hundred years ago but early dynamometers did not benefit from the technological advances until the last hundred years. A John Deere Model E hit-and-miss engine has a nominal power of3hp. The purpose of this project was to analyze this engine, including verifying power.
Outcomes of the analysis of this engine include brake horsepower and thermal efficiency. The first step was to put the engine under a load. This was done with a water pump system. Pressure, water flow, and rotation were measured from tests using the system.This type of system is analogous to a water brake dynamometer used in industry.
Results of the analysis were hindered due to unknown efficiencies of the transmission belt and pump. These quantities can be found by using a motor with known power output. The entire system's output was .35hp and an angular velocity of47-37 radians per second.
