A method of increasing an economic efficiency of a combustion system 10 run with alcohol fuels (such as methanol and/or ethanol) is concerned with injecting a controlled quantity of fuel additive into the engine 20. The method includes using an injector for the fuel additive (e.g. Avocet), injecting the additive and/or fuel directly into the combustion chambers of the engine block 20; and using a control arrangement 80 for controlling a quantity of the fuel additive which is injected. The control arrangement includes a computer linked to a temperature sensor 70 placed in or on the engine block 20, and controlling a flow rate of an electronic fuel injector, where the flow-rate of fuel is controlled by a power control, such as a vehicle accelerator, for controlling output power from the engine block. The efficiency is improved by reducing the amount of additive required, this reduction being made by the controlled use of the fuel additive as a function of combustion engine operating parameters, such as engine temperature. |
