IC engine running on fat-alcohol mixture - comprises conventional engine modified by replacing valves and distributor with oxygen fed from tank

摘要

The i.c. engine is intended (or modified) for running on fat of vegetable, animal, or mineral origin. Oxygen is supplied from a bottle (1), via an adjustable reducing valve (3) to solenoid- operated inlet valves (6). The fat is mixed, e.g. with methanol, to produce a permanently liquid fuel. The fats selected should be free of resin, salts and acids. The fuel is held in a tank (7), which is pref. adjacent to the engine block and insulated. It is admitted to the cylinders, via non-return valves (9), together with pressurised air, pumped from the container (12), through solenoid valves (10) operated by a distributor (11). Power output is controlled by controlling the oxygen supply.
