By cooling the intake air of a turbocharged 9f-litre oil engine, its torque output was raised by 23 per cent., and maximum torque occurred at an engine speed 10 per cent. lower than before. Mr. E. Kellett, C.A.V., Ltd., gave these facts to the Institute of Road Transport Engineers in London last week.
The cooler was 1 ft. 6 in. square and 7 in. deep, and incorporated a I h.p. fan. With the turbocharger set at a pressure ratio of 2 to 1, a cooler could increase maximum power by 70 per cent. compared with a normally aspirated engine.
Properly matched turbochargers could reduce fuel consumption by 7-17 per cent. A 5-per-cent. saving would enable the cost, of a turbocharger installation to be recouped in a 'year with a vehicle covering 1,000 miles a week.
By varying the degrees of pressure charging, engine manufacturers, said Mr. Kellett, could now offer a basic unit having a wide range of outputs. An extension of this trend would be made possible by cooling intake air, but this practice had to be proved acceptable.
