Program for Determination of Effect of Engine Design on Acceleration ¹

SO FAR, all Cooperative Fuel Research acceleration tests have been made on one engine. Hence, to make these results generally applicable, it is necessary to know the effect of engine design on the various factors influencing acceleration. For this purpose, a portable model of the previously described spark accelerometer has been designed. With this apparatus, identical series of acceleration tests will be made on about ten representative automobile engines at the manufacturers' laboratories.
