Natural gas or bio-gas are possible alternative fuels to petrol in Otto-cycle engines. A commercial, single-cylinder, spark-ignition engine has been run on various mixtures of natural gas with carbon dioxide to gain experience of its operation and compare ist behaviour with operation using petrol. While there was a considerable drop in power with straight natural gas, the specific fuel consumption was not greatly affected. No attempt was made to advance the spark timing or to increase the compression ratio although both of these changes would be expected to improve the performance considerably. When operating on gas, it was found possible to vary the power of the engine over a wide range by varying the mixture strength, as in a diesel. Performance was little affected by increase of carbon dioxid content up to 47 %. (Buehn)
