To meet the regular global emission norms, the transition of fuel development stages was incorporated in petrol/gasoline engines from Carburetor type to Throttle fuel injection/Single point petrol injection and throttle injection to Port/Manifold fuel injection. To achieve advanced emission norms, conventional or manifold fuel injection (MPFI) engines are replaced by Gasoline Direct Injection (GDI) engines. To attain efficient range of fuel economy, power output and controlled concentration of emissions coming out of an engine exhaust, the control of ignition timing and fuel injection timing is much important. In this work, the electronic hardware part includes controller/Arduino with ignition control and fuel injection drivers used for controlling both ignition timing and fuel injection timings. In order to control these timings, the position of piston with respect to TDC was measured with the help of crank and cam position sensors. Software required for ignition and fuel injection timings with crank and cam position are developed for controlling an engine with Arduino and drivers. © 2021 Elsevier B.V., All rights reserved.
