NEW MOTOR FUEL.
THE USE OF CHEMICALS. The Director of the Australian Institute of Science and Industry draws attention to the important fa<*t that American research has recently developed a new material destined to be of considerable importance to the motor industry. One of the chief disadvantages of ordinary petrol is that it cannot be used with ‘'knocking’’ in engines having an initial compression of greater than about 1001 b per square inch. Consequently the efficiency of a petrol engine is low. The General Motors Research Corporation, however, has developed certain chemicals containing the ‘'ethyl” group, which when added in very small amounts to ordinary petrol enables the mixture to be used in engines of milch higher compressions than 1001 b per square inch. These chemicals thus enable petrol to be used much more efficiently than has* formerly been the case, and as a result the mileage per gallon of an ordinary car can be very considerably increased. The chemicals used are not yet on the Australian /narket, frut in the above cor*
poration has just commenced marketing them on a large scale.
