FOLLOWING the successful tests carried out at the Research Deparkment of the Institution of Automobile Engineers, in connection with the running of an A.E.C. oil, engine on producer gas, the Institution has now released information relative to the Gardner 5LW oil-engine conversion.
The test results show that the mixing valve developed by the I.A.E., and which was described in detail in our issue• dated July 2, gives satisfactory results in this engine. Limitation of fuel injected can be effected without alteration to the internal parts of the fuel pump, and satisfactory running was experienced, using approximately 25 per cent. of the normal fuel-injection quantities.
It was fciund necessary, says the I.A.E. report, to advance the injection timing from the standard 27 degrees to 33 degrees before top-dead-centre on the crankshaft.
Operators who.are' interested in the conversion of their Gardner oil engines to run on produces gas should make contact with the Directorate of Alternative 'Motor Fuels, Ministry of War Transport, to which authority any further information, if and when it becomes available, will be communicated.
