SUMMARY OF TEST. The chief points of interest in connection with these tests are :- (1) High efficiency of engine. (2) Less range of ignition advance required than EAC. (3) Position of sparking plugs reduce detonation. (4) No definite periodic crankshaft vibration. (5) Valve gear noisy - camshaft drive noisy - piston knocks.
