✦ Synopsis
A way of achieving quality regulation in running a conventional internal combustion engine is presented. The fuel stream (methanol) is divided into two parts one of which goes to a conventional fuel injection device, the other to an onboard decomposing reactor for the production of the necessary hydrogen. The reactor methanol flow is taken as proportional to the air flow to the carburettor, i.e., to the rotational speed in the quality regulation region. This rather easily achieved system is evaluated using a model calculated to include most of the parameters. Information is also included on the necessary regulation equipment. The resulting low emission of hazardous gases, as reported earlier, is an advantage but the main interest is in the high efficiency of the engine. To verify the calculations benchscale tests were carried out. The differences between the model and the test results are analysed.
