Maintenance of Car – Save your money & yourself

This article is all about car parts and maintenance; and some tips about how to save your money and save your car as well. The main parts of a car, as we all know, are its engine, combustion chamber, the block, gaskets.

Some cars also feature air conditioning system for better comfort. Whatever it is learning about these parts make it very easy for you to deal with these things.

Engine

This portion explains how automobile engines work. The illustration below shows the basic parts of a “V-8′ internal combustion engine. Internal combustion means fuel burns inside an engine, in combustion chambers. Other types include the steam engine and the jet engine. Although there are many designs, the parts shown below are used in almost all automobile engines.

Car engine parts

Combustion Chamber

Fuel burns in combustion chambers inside an engine. The walls and ceilings of these chambers are hollowed into an engine head. The floor of a combustion chamber is also the top of a piston, which moves up and down as an engine runs. One combustion chamber is directly above each cylinder, with a piston sliding in each cylinder. The explosive force created inside a combustion chamber pushes a piston down, creating the motion which moves a car. As an engine runs, pistons pump up and down, one after another, in a carefully-arranged order. This up and down movement changes to spinning motion by the action of a crankshaft, the spin motion, or angular momentum, then rotates the wheels. An automobile engine really has just one job—to create spinning motion.

Block

An engine block is the most basic part of an engine. A block is a large casting of iron or aluminum with small passageways for oil and water circulation. A block itself, however, has no moving parts. Several large holes or tubes, called cylinders, are built into each engine
block. Pistons slide up and down in these cylinders and each engine will have the same number of cylinders, pistons, and combustion chambers. Automobile engines usually have four, six, or eight cylinders commonly arranged in either a straight line or a “V” shape.

Gaskets

Gaskets prevent leaks between the connecting surfaces of many car parts. Gaskets are made of cork, copper, rubber, thick paper, or various combinations of these materials. When bolted down and squeezed between two surfaces, a gasket fills in gaps. If squeezed too tight, a gasket can be distorted and pushed out of position, causing a leak.

Simple head gasket diagram

A complex metal and fiber head gasket is used between a block and a cylinder head. Cork gaskets are often used for valve covers and the oil pan or crankcase. Thick fiber and paper gaskets are usually used with water pumps and carburetors. Circular rubber gaskets are found on most oil filters. Asbestos and fiber gaskets are used for exhaust manifolds and flange gaskets.

Air Conditioning

Air conditioning system uses the same principles of cooling as a home refrigerator. A liquid refrigerant circulates in a closed system. A compressor pump pressurizes this refrigerant, changing its boiling point, and causing it to vaporize. A radiator, or condenser, located in the front of a vehicle, cools the circulating vapor, changing it back to a liquid. This cycle of changing back and forth from liquid to vapor maximizes the amount of heat absorbed. A second radiator, an evaporator, becomes cold during this process and air blown over its cool fins is then directed into the passenger compartment through larger pipes called ducts.

Car air conditioning system

An expansion valve controls refrigerant pressure, boiling point, and volume. A sight glass is used to observe the number of vapor bubbles that remain in the liquid refrigerant as it leaves a condenser. The number of bubbles indicates the volume of refrigerant.

Car Radar Detector

Many other devices are associated with this system, including: check valve, oil bleed line, capillary tube, suction throttle valve, equalizer line, and receiver-dehydrator. Usually automobile air conditioning systems share the same blower, air ducts, and vents with the heater.

Safety Tips

  1. Drive sensibly, courteously, and soberly
  2. Use seat belts (lap and shoulder)
  3. Drive a well-maintained car
  4. Clean windows and mirrors often
  5. Drive a car with air bags
  6. Choose a car with ABS brakes
  7. Drive in a middle lane of the freeway when possible
  8. Drive with the traffic flow
  9. Think ahead and look behind, use the rear view mirrors often
  10. Carry a safety kit in your car trunk (flashlight, flares, tire inflator, etc.)
  11. Carry a cell phone for emergencies, but please don’t talk while driving
  12. Stop at stoplights and stop signs a few feet back from the crosswalks
  13. Join the AAA car club in your area
  14. Anticipate trouble from all directions
  15. Take road rage to a gym

Money Saving

  1. Start with a good car, then work to improve it
  2. Learn How Cars Work and then work on them
  3. Locate a competent mechanic by word of mouth, not local advertising
  4. Tune a car to use the lowest octane gasoline possible
  5. Avoid unnecessary idling, turn off an engine while waiting in long lines
  6. Keep tires inflated to maximum pressure
  7. Rotate tires and change engine oil every 3,000 miles
  8. Avoid fast starts and stops
  9. Drive slower than you think you should
  10. Don’t pass highway patrol cars or make eye contact with police officers while driving.

Follow the instructions and keep yourself safe as well as your money. This simple it is.
