The advantages and disadvantages of alternative fuels and drives show that synthetic petrol from coal and alcohol are the most suitable alternative fuels. An additional advantage for alcohol is that it can be manufactured from various raw materials. A further advantage is that under particular conditions alcohol may be mixed with petrol as required. Because of its availability methanol is probably the most favoured alternative in European countries. In the production of methanol from coal, the coal is vapourised into synthetic gas and finally this gas (carbon monoxide and hydrogen) is synthesized into methanol. From 1985 increasing quantities of methanol from natural gas conversion and from pilot installations for coal liquefaction are likely. These will be mixed with the fuels in differing concentrations. In respect of its energy content, methanol could today be produced at more favourable prices than petrol. The first results from large scale tests with M 15 (mixture of 15% methanol and 85% modified petrol) show that neither more nor less fuel is consumed. The carbon monoxide exhaust is reduced in vehicles with carburettors by 30%, in vehicles with injectors only minimally. Hydrocarbons in the exhaust are reduced by 15% for carburettor vehicles, by 15 to 20% for injector vehicles. Nitric oxide increases only in vehicles with injectors by some 10%. No differences were established in vehicle handling. (TRRL)
