Hsl/LG15.1.25 OBJECT OF TEST. INVESTIGATIONS ON EAC. CARBURETTER. TESTER. A.C. Lovesey CONDITIONS. Test bench, and road tests. SUMMARY OF TEST. EAC. CARBURETTER. The attached report in connection with the EAC. carburetter explains the difficulties we encounter when we attempt to use a larger carburetter or work with a lower depression than the standard 40/50 HP. The tests confirm the experience gained on the Kwave and 20 HP. carburetters, that we cannot depart from the 40/50 proportions if we wish to retain correct metering over the whole range of conditions. As regards the EAC., it will be seen by the power curves that a loss of 2 to 3% in power we can overcome the difficulties and retain the same characteristics as we have on the 40/50 carburetter. We are recommending that all the EAC. carburetters should be made with the 40/50 proportions. [Handwritten note in right margin]: Encl to earlier work | ||
