EFFECT OF GOVERNORS ON PASSENGER CAR PERFORMANCE

INVESTIGATIONS ARE MADE TO ESTABLISH AND RECORD THE EFFECT OF GOVERNORS ON THE PERFORMANCE OF CURRENT PRODUCTION PASSENGER CARS. TWO TYPES OF GOVERNORS WERE TESTSED. BOTH WERE ADJUSTABLE. ONE WAS A THROTTLE TYPE GOVERNOR WHICH CONTROLLED ENGINE SPEED (CAR 1), AND THE OTHER ONE WAS AN EXPERIEMENTAL GOVERNOR DRIVEN OFF THE SPEEDOMETER (CAR 2) SHAFT WHICH CONTROLLED CAR SPEED. THE CARS WERE OF THE SAME MAKE BUT DIFFERENT MODELS, EQUIPPED WITH HYDRA-MATIC TRANSMISSION. FULL THROTTLE ACCELERATIONS WERE MADE FOR A STANDING START ON A LEVEL STRAIGHTAWAY UNDER VARIOUS CONDITIONS OF GOVERNOR ADJUSTMENTS. MEASUREMENTS WERE TAKEN OF TIME, DISTANCE TRAVELED, ENGINE RPM, AND CAR SPEED. FROM THESE DATA, VARIOUS ASPECTS OF CAR PERFORMANCE AND RELATIVE PERFORMANCE WERE CALCULATED. THE DATA INDICATED THAT A GOVERNOR COULD BE DETRIMENTAL TO ACCELERATION AND PERFORMANCE.
