Show Warming Intake Helps Engine's Acceleration Warming the intake manifold will aid the engine's ability to pick up j speed very materially, according to I 'recent tests conducted by tlie bureau i of standards.. The same tests showed that even a considerable difference in Jacket water temperature has but flight effect upon car acceleration. The tests were made on a six-cylinder 1926 engine. A change in the jacket water temperature from 212 iegrees to 54 degrees appeared to make but slight difference, while a change of the temperatui.- of the intake in-take manifold from 150 degrees ' to 172 degrees resulted in marked improvement im-provement in acceleration. |
