It is suggested that you look for the answers to these questions as you go through the lesson.
  3. 3. Vehicle Components and Systems Purpose: Become acquainted with a vehicle’s main systems and components in terms of their purpose, safe and legal use, maintenance, and certain economic considerations.
  4. 4. <ul><li>Vehicle Systems and components </li></ul>Vehicle frame and body: The purpose of a vehicle’s frame is to support the body, engine, and other components. The frame itself is supported by the wheels and tires through the vehicles suspension system. Vehicle Frame
  5. 5. <ul><li>Vehicle Systems and components </li></ul>The engine: When you start your car: (a) power from your battery is used to operate a small electric motor called the starter motor, (b) the starter motor turns the flywheel and crankshaft of the engine so that the engine can attain sufficient momentum and speed to start and run on its own, (c) delivering rotational power to the crankshaft which supplies power to the remainder of the power train. Crankshaft Spark Plug Battery Engine
  6. 6. <ul><li>Vehicle Systems and components </li></ul>The engine: This power is ignited by exploding gas inside cylinders which drives pistons up and down, through connecting rods. Inside the pistons a mixture of compressed air and gas is delivered to the cylinders by a carburetor and intake manifold or a fuel injection system. The moving parts of the engine must be lubricated. Oil which accumulates in your engine’s oil pan is pumped by the oil pump through an oil filter and then through tubes that deliver the oil to the moving parts to be lubricated. Oil and Oil Filter
  7. 7. <ul><li>Vehicle Systems and components </li></ul>Question: What is the name of the system that moves the gasoline to the engine?
  8. 8. <ul><li>Vehicle Systems and components </li></ul>The fuel system: Fuel and air is delivered to the engine through components which include: (a) the fuel tank which is used to store the gas, (b) a fuel pump which pumps the gas from the tank through a fuel line and furl filter to a carburetor or fuel injection system. This fuel injection system or carburetor delivers the proper mix of air and gas to the cylinders by means of an intake manifold after passing through an air cleaner. Question: What is the name of the system that moves the gasoline to the engine?
  9. 9. Question: What is the name of the system that transmits power to the wheels? Drive shaft Transmission Differential
  10. 10. The power train system: A vehicle’s power train consists of components that generate and transmit power to the wheels. In a rear wheel vehicle automatic vehicle, it includes: (a) the engine which generates the force, (b) the transmission which adjusts and controls the engine’s RPM and changes the gears, (c) the drive shaft which transmits forces from the transmission to the rear of the vehicle into the differential which allows the axels and back wheels to turn. In a front wheel drive vehicle, the power is transmitted from the engine through a combination transmission-differential and then to the front wheels. In a four-wheel drive vehicle, power is transmitted from the transmission to a transfer case which can transmit power to either the rear wheels only or to both the rear and front wheels. Question: What is the name of the system that transmits power to the wheels? Drive shaft Transmission Differential
  11. 11. Muffler Exhaust Pipes Question: What is the name of the system that removes the emission gases into the environment?
  12. 12. The exhaust system: After gas is exploded in one of the cylinders it is released into an exhaust manifold which collects it and passes it to a catalytic converter which chemically reduces the quantity of harmful pollutants. The gases are then passed by exhaust pipes through a muffler and resonator which reduce the noise. The gasses are then moved to the tailpipe which vents the hot air away from the vehicle. Muffler Exhaust Pipes Keep your exhaust system in good working order by noticing changes in noise, fumes, and rattling. These all signal problems. Eventually all vehicles need replacement exhaust components. Question: What is the name of the system that removes the emission gases into the environment?
  13. 13. Question: What is the name of the system that prevents the engine from overheating? Radiator
  14. 14. The cooling system: Heat caused by the friction of moving engine parts and the explosion of gasoline is removed through the vehicles cooling system. In this system, heat is absorbed by coolant flowing through passages inside the engine. The coolant is a mixture of water and chemicals that protect the cooling system from corrosion, lubricate the water pump, and prevent freezing. It is stored in the radiator which transfers the heat to the outside environment. The radiator is cooled by a fan, and most have a recovery tank to capture coolant as it expands due to the heat, and returns it to the radiator when it cools. This coolant also allows your engine to heat up to its proper operating temperature and is controlled by a heat sensing valve called a thermostat. Question: What is the name of the system that prevents the engine from overheating? Radiator
  15. 15. Question: What is the name of the system that starts the motor?
  16. 16. Question: What is the name of the system that starts the motor? The electrical system: The battery is your vehicle’s primary source of electrical power. When you turn on your ignition switch to start your car, electricity is used to close another switch called a solenoid that transmits the large amount of current needed to turn the starter motor. Once your engine is running, power is generated by the alternator, which also keeps your battery charged . Then there is a voltage regulator, distributor, and coil which controls the amount of electricity needed by the spark plugs. Electricity is distributed throughout your vehicle by various electrical circuits for lighting, computers, radio, interior cooling, heating, etc. These circuits have fuses to disable a circuit that is drawing too much current so as to prevent a fire and protect the components that the circuit serves.
  17. 17. Question: What is the name of the system that makes it possible to turn the car?
  18. 18. The steering system: A vehicle’s steering wheel is attached to a steering column or shaft which terminates in the steering box. Inside the steering box, the turning motion of the column is translated into lateral motion which is passed on to the wheels through a series of components which include ball joints, the steering arm, and steering knuckle. In power steering systems, turning the steering wheel actuates a hydraulic system which amplifies the force necessary to rotate and move the linkages leading to the wheels. With power steering there should be no “free play” in the wheel. When you turn the steering wheel in a power steering system, the hydraulic fluid is compressed inside a cylinder. This compressed fluid is then transmitted by hydraulic lines to a piston which amplifies the force making it easier to turn the wheels. Question: What is the name of the system that makes it possible to turn the car?
  19. 19. Question: What is the name of the system that helps ease the jarring effect of potholes? Coil Springs and Shock Absorbers
  20. 20. The suspension system: The purpose of your vehicle’s suspension system is to connect the wheels to the frame and body and keep the movement of your wheels from being transmitted fully to the body of the vehicle. This allows you to maintain control of the car in turns, when you hit potholes, and on rough roads. It makes riding in the car more comfortable. As the up and down movement of your wheels is absorbed by the springs in your suspension system, your shock absorbers keep the springs from continuing to bounce. There are are different designs for suspension systems involving various linkages, struts, joints, torsion bars, and so on. Question: What is the name of the system that helps ease the jarring effect of potholes? Coil Springs and Shock Absorbers
  21. 21. Question: What is the name of the system that stops the car?
  22. 22. The braking system: There are two independent braking systems in your vehicle, the service brakes and the parking brake (also referred to as the emergency brake). The service brakes are used to slow your vehicle while you are driving. The parking brake can also be used to slow your vehicle in an emergency, but is mainly used to hold your vehicle in one place while stopped or parked. When you press your brake pedal, a piston in your master cylinder forces the brake fluid through the hydraulic lines to pistons in the wheel cylinders at the wheels where additional pistons provide the force to apply your brakes. Hydraulic fluid is stored in a brake reserve normally located in the engine compartment. Question: What is the name of the system that stops the car?
  23. 23. The braking system: Both drum and disc brakes convert friction force to heat and if the brakes get too hot, they cease to work because they cannot dissipate enough heat. For both types of brakes, your stopping time is roughly proportional to the square of your speed. So, if you double your speed you increase your stopping distance by four times! Your parking brake uses a cable to engage the brakes or clamp down on the drive shaft, and will function even if your service brakes fail. There are two types of brakes: (a) drum brakes and (b) disc brakes Drum brakes slow your vehicle by the friction of a brake shoe pushing against the drum which is rotating with the wheel. Disc brakes slow your car by the friction of a caliper pressing against a disc which is rotating with the wheel. Question: What is the name of the system that stops the car?
  24. 24. <ul><li>Vehicle Systems and components </li></ul>The braking system: If the wheels are locked as in the case of a skid, the drums or discs are not moving and there will be no friction. Brakes will only slow your car while there is friction between the moving parts of your brakes. The purpose of the antilock braking system is to prevent the brakes from locking by first sensing that they are locking then automatically, rapidly releasing and applying pressure. If you do not have antilock brakes, you can avoid having your brakes lock manually, rapidly releasing and then reapplying pressure to your brake pedal.

  43. 43. Driver Controls: If a gauge or panel light is not working or does not appear to be providing correct information, it should be immediately repaired or replaced. Failure of instrument panel indicators can lead to incorrect decisions on your part which can cause an accident, breakdown, being stranded, and damage to your engine and other components which could have been avoided.
  44. 44. <ul><li>Vehicle Systems and components </li></ul>Vehicle maintenance: fuel system: Leaks in your fuel system can cause fires and expose you to toxic gases. The leaks can occur in the fuel tank, fuel lines, fuel pump, carburetor, fuel injector lines and even by not having your gas cap secured attached. If you smell gas you should immediately stop the car, turn off the engine and determine the problem. Your fuel system should be checked for leaks as part of regular maintenance.

  84. 84. <ul><li>Vehicle Systems and components </li></ul>The legal use of safety equipment: Windows, mirrors, and defroster You must have mirrors which provide a view for at least 60 meters to the rear of your vehicle. Two mirrors are required on all vehicles. A right side mirror is required and either a a rear view or left side mirror. You should properly adjust your mirrors before starting to drive, to avoid being distracted while attempting to adjust them during driving.
  85. 85. <ul><li>Vehicle Systems and components </li></ul>The legal use of safety equipment: Windows, mirrors, and defroster Maintaining good visibility requires that you keep your windshield and mirrors clean and free from obstruction. If your windshield is cracked and obstructs your view or that of your passengers, you not be allowed to take your driving test. You must not carry objects, inside or outside, which obscure your view.
  86. 86. <ul><li>Vehicle Systems and components </li></ul>The legal use of safety equipment: Windows, mirrors, and defroster Maintaining good visibility requires that you keep your windshield and mirrors clean and free from obstruction. If your windshield is cracked and obstructs your view or that of your passengers, you not be allowed to take your driving test. You must not carry objects, inside or outside, which obscure your view. Over time windshield wipers lose their ability to effectively clean your windshield by cracking, loosing their flexibility, becoming dirty and getting out of adjustment. It is a safe practice to change them yearly. Temperature and humidity conditions may change rapidly causing frost and condensation to form on the windshield. For this reason it is important to keep the defroster in good operating condition.
