KNOWLEDGE
Car

Hey Buddies! Have you ever thought of how the car runs, how it starts and how it functions. Here is the description about it. BATTERY: It is a device, which stores electricity so that it can be used later. Car batteries are heavier and lasts longer than the torch batteries

BUMPER: A piece of a plastic or metal at the front or at the back of the car body helps to prevent the car from getting damaged in a minor accident

CONVERTIBLE: A car with the roof can be folded down so that the passengers are in the open air.

CYLINDER: A hole in an engine- The shape like a fizzy drink can- where the fuel burns. Piston moves up and down in the cylinder. There are also cylinders in the brakes. Piston moves out of them to make the brakes work.

DASH BOARD: The panel of switches, lights and dials in front of the drivers.

EXHAUST: A long pipe that takes the waste gases from the engine and releases them in to the air behind the car. FOUR CYLINDER ENGINE: An engine with four cylinders. Some engines have 6,8 or even 12 cylinders to make them more powerful.

FUEL: A liquid that is burned inside the engine to make the engine work and the car moves. It is stored in the fuel tank.

GEAR WHEELS: Metal disc with teeth around the rim that lets the car go faster or slower or forward or backward. INDICATOR: Flashing lights at the each corner of the car, that tell other drivers that the car is going to take the turn. PISTON: A piece of a metal that moves up and down inside the cylinder of an engine. As it moves it turns the Crankshaft. CRANKSHAFT It goes into the gearbox.

POWER STEERING: Steering that helps the drivers by making the steering wheel easier to turn silencer box. A metal box that is part of a car’s exhaust pipe. It makes the engine much less noisy.

CAR ENGINE: The engine makes the car move. Inside the engine there are the chambers called cylinders. Inside each cylinder is a piston, which moves up and down. Fuel such as petrol, diesel, gas etc is burned by the spark plug. The fuel explodes when it burns. The explosion pushes the piston down, which turns the crankshaft. As the crankshaft turns, it makes the wheel goes round and the car moves. The fastest car in the world can travel at 633 km per hour.

GEARS: Most cars have 4 or 5 gears. Some gears are for starting and driving slow, others are for driving fast or reversing. Gears are made up of many toothed wheels fixed to rods (shafts). The teeth of the two gear wheels fit together and one wheel turns the other. Big gear wheels turn the shaft to wheel faster than small gear wheels.

CHANGING GEARS: In some cars, gears change automatically. The gear’s lever is used for driving forward (D), reversing (R), N is the neutral meaning no gears. P for parking gear. In the other cars, drivers change gears manually using the gear’s lever from 1-4

CATALYTIC CONVERTER: All new cars have a special part in the exhaust pipe caused catalytic converter. It gets rid of some of the poisonous gases in the engine and cuts down the pollution.

WHEELS: Hubcaps cover the new bolts that fix the wheels to the car.

TYRE: Tyre is made of rubber, filled with air. It is the only part of the car that touches the ground.

WHEEL RIM: It holds the tyre in place. It is made of steel or aluminum.

SPRINGS: It lets the wheel moves up and down slightly. This gives a smooth ride on bumpy roads.

THE BRAKES: It slows down and stops the car. Each wheel has its own brakes. The front wheels have disc brakes and the rear wheels usually have “druon” brakes. The driver presses the brakes. The break pedal is connected with the brakes by pipes filled with liquid called brake fluid.

ABC BRAKES: It is a steel disc attached to wheel by a pad on each side. When brake fluid reaches the brakes the pad presses against the disc and slows down wheel.

DRUM BRAKES: It has a metal drum fixed to wheel. When the brakes fluid is pumped to the brakes, the shoes press against inside of drums. This slows down the wheels.

STEERING: Steering wheel turns the front wheel from side to side. In some cases, fluid in a system of pipes is used to help turn the wheels. This is called power steering. It makes easier for the drivers to turn the car.

Think on your own. Ask questions to yourself and find out the answer. Ask your parents, teacher, see in encyclopedia, internet etc. When you find answer on your own, helps you remember it fast and for long time. When you find answer to the question which doesn’t have any answer in the world and you find the answer, you will become scientist
