Abstract

Engine tuning was always a major concern for cars manufacturers and cars users and many researches have been performed to make the engine tuning cope up with the modern world requirements for controlled pollution laws, economic fuel usage and to make the engine in a good condition for longer time. A transition state between carburetors which have no mechanical ability to correct lean or rich fuel mixtures until the 1980s and the current Air to fuel (A/F) ratio control method using oxygen sensors implemented in the car exhaust was the carbon monoxide potentiometer which was used to keep the A/F ratio at a certain level using a potentiometer to achieve an ideal fuel consumption and engine performance, but this method requires a frequent check by the car user and a mechanic assistant which makes the engine tuning for these cars (old cars which normally require tuning more frequent than the new cars) a difficult process and has a limited flexibility for the car user to make his own choice on the car performance as well. By using microcontrollers which can work perfectly with the engine control unit (ECU), this potentiometer can be replaced and can allow the user to do the tuning through different buttons which will make the tuning process simpler, more accurate and more flexible with more tuning options for the car driver, beside some more functions that will enhance the engine performance and fuel consumption in general and the ability to change any time from the old system (CO potentiometer) to the new embedded tuning device.
