2424WORKING OF AN ENGINEThe working of an Engine can by simply explained by the following steps; Air-Fuel mixture is taken inside the cylinder, (INTAKE STROKE)The mixture is compressed, (COMPRESSION STROKE)Due to compression, the mixture is Ignited or burnt to produce Power, (EXPANSION OR POWER STROKE)The Waste gases are thrown out or expelled in the form of Exhaust gases. (EXHAUST STROKE)

25Power is generated inside the engine only during the power stroke, when compressed Air Fuel mixture is ignited and exploded (process of combustion). This process of 4 strokes is repeated to keep the engine running.25PETROL ENGINE OPERATION

My Car113It is a system which gathers information from various modules and displays on the instrument cluster (eg: door ajar reminder, service reminder, trip data, fuel consumption etc.) The Driver can also conveniently set a few parameters of the car (e.g. Passenger Airbag activation, speed limit buzzer, automatic door lock etc.). 113MyCar BasicBuzzer Setting for Speed limitClock SettingBuzzer volume settingDistance unit settingMyCar AdvancedBuzzer Setting for Speed limitTrip B ActivationClock settingDate SettingRadio DisplayAutomatic Door LockSetting Units for Distance, Range & TemperatureButton Beep Volume AdjustmentCheck Service ReminderFront Passenger Airbag ActivationMy Car114It is a system which gathers information from various modules and displays on the instrument cluster (eg: door ajar reminder, service reminder, trip data, fuel consumption etc.) The Driver can also conveniently set a few parameters of the car (e.g. Passenger Airbag activation, speed limit buzzer, automatic door lock etc.). 114Blue & Me is an innovative system built by Fiat along with Microsoft. It allows you to use Bluetooth mobile phone in the car and to listen to music in digital format

Blue & Me can be controlled either by buttons on the steering wheel or by voice, so that your attention is not distracted from driving and the road
