As it combusts, heat is created. Heat and the expansion of air caused by heat is what drives the pistons. The pistons drive the crankshaft, the crankshaft drives the flywheel, the flywheel drives the input shaft to the transmission, the input shaft drives a series of gears in the transmission, which in turn drives an output shaft to the differential, and from there you get power to your wheels. That's the nickel tour of how it works. The crankshaft will also drive other components, such as your belt pulleys, camshaft, etc.
if cars do not have petrol they will not work because petrol burns in the engine and the car moves forward
It burns up and goes to the engine to power it so your car can move

You cannot use water in an engine instead of petrol. The internal combustion engine of a car or truck requires the ignition of gases in order to create power. This doesn't happen with water.
Who told you it is harmful? It is only harmful if it is a Diesel engine. If it is a petrol (gasoline) engine then Petrol is what it takes to run.
CO2 and water
Yes, putting petrol/gasoline in a diesel engine and running it will cause severe damage to the engine.
A car runs on diesel or petrol depends on the engine of the car
Oxygen and petrol or diesel is burned in a car engine, it is not formed
your car stops
Car will run poorly if at all.
