The invention concerns a fuel comprising a mixture of at least one alcohol and at least one ether. The ether conveniently has a boiling point below 200.degree. C., preferably below 100.degree. C. The fuel can comprise lower aliphatic alcohols and ethers. An engine may be run on the fuel by injecting the constituents separately or as a mixture. The fuel may optionally contain diesel fuel and/or castor oil.

Fuels

The invention concerns a fuel comprising a mixture of (A) at least one alcohol with an average molecular weight of less than 160, and (B) at least one further organic compound which has a spontaneous ignition temperature of less than 450.degree. C. The further organic compound is selected from

The invention concerns the modification of a compression ignition engine by providing a device which converts an alcohol to an ether. The device comprises a heat exchanger having an inlet to receive the alcohol and an outlet in communication with the inlet end of a catalytic conversion chamber, said catalytic conversion chamber containing a catalyst capable of converting an alcohol to an ether and having an outlet pipe for leading the ether to a cylinder of the compression ignition engine, and mounting means adapted to enable the device to be fitted to a suitable part of the compression ignition engine.
