EVALUATION OF MOTOR FUELS FOR HIGH-COMPRESSION ENGINES

THE striking advantages of high-compression engines - both in terms of increased power and lower fuel consumption-are emphasized here.

This paper reports the results of a series of tests on a high-compression test engine arranged to permit operation at compression ratios from 6/1 to 12/1. The behavior of a variety of experimental and commercial gasolines was studied over this range of compression ratios.

Bhp gains as high as 26% resulted when the compression ratio was increased from 6/1 to 12/1. Similar gains in fuel economy resulted.
