Intake: the piston is pulled down inside the cylinder, by the momentum of the crankshaft. Most of the time the car is moving along, so the crankshaft is always turning/moving. The inlet valve opens letting a mixture of fuel and air into the cylinder through the pipe.
Compression: the inlet valve closes. The piston moves back up the cylinder and compresses the fuel-air mixture which makes it more flammable. when the piston reaches the top of the cylinder, the sparking plug.
Power: the spark ignites the fuel-air mixture causing mini explosions. The fuel burn immediately, giving off hot gas that pushes the piston back down. The energy released through is now powering the crankshaft.
Exhaust: the outlet valve opens. As the crankshaft continues to turn, the piston is forced back up the cylinder for a second time. it forces the exhaust gases out through the exhaust outlet.

Electric cars obviously are powered by electricity. Instead of gasoline there are usually several large batteries to store the power. The batteries are not only used to power the car but to use the wipers and lights. Electric cars looks completely like normal cars but lack the exhaust system. However the interior of the the cars system is very different. For instance you will not find a gas tank because they do not use fuel to propel the engine. Instead of having a engine, electric cars have one ore more motors to drive the gear box and wheels. An electric motor is a tightly wrapped coil of wire that can spin around freely inside an out casting a powerful magnet. When electricity is fed into the coil, it generates a magnetic field that makes the coil rotate very quickly. Inside the magnet the spinning coil is fastened to an axle (central shaft) that can be used to drive the cars wheels. some cars have 4 motors that are built into the wheels aka the hub motor.
Electric cars don't all work the same way. some have fuel cells instead of batteries. These are a bit like batteries that never run down. They take hydrogen gas, from a tank and convert it into a steady supply of electricity. solar cars work a little differently, they have large solar panels on their roofs or built into their bodies and use this to charge up their batteries as they go along.
There are many different opinions about electric cars. It is safe to say that there is not one oil company that likes electric cars, but what about everyone else? The community has a lot to say about electric cars. For example, a lot of parents support electric cars because they are environmentally friendly- however, many don't because they are dangerous. The batteries used in electric cars are known to catch fire easily and explode. Parents also dislike how quiet they are. Some are worried that their kids won't hear the car, which may lead to getting hit easier.
There are many pros about electric cars, for example: you do not have to pay for gas anymore, you are helping the earth by not using gasoline and avoiding creating extra pollution. Also, the Tesla model S passed the crash test, and is the safest car on the road. They earned five stars for every safety test it did. There are very many cons also, for example: electric cars are not very ascetic, and don't have very good range. Most electric cars can only travel around two hundred kilometers on a single charge, which is another con. Electric car batteries take a very long time to charge, and there are not a lot of places to charge your car. Many cares take up to sixteen plus hours to fully recharge. Electric cars are very expensive too. Most are above twenty thousand and above.
Most car companies like electric cars. They think that it is a great way to save money while having an reliable source of travel. The car companies that don't like electric cars, strongly believe that they are a waste of time, and money.They believe that instead of completely remaking the car engine, we should spend our time learning new ways to make more fuel efficient cars and making systems that don't cause so much pollution.
