Fuel System
Fuel Injection System
Deliver exact amount of fuel to engine
Reduce the amount of pollution-causing gases
Fuel Efficiency
Depends upon:
Weight of car
Speed you drive - over 55 fuel efficiency decreased
Air resistance: keep windows closed when driving over 45 mph
Fuel Efficiency Continued
Also depends upon:
Type of engine - 4 or 6 cylinder
Vehicle Design
Manual vs Automatic
Power equipment - air conditioning
Know how to calculate your MPG
Used 10 gallons of fuel to drive 150 miles : 150 divided by 10 = 15MPG
You have 10 gallons of fuel. Your car delivers approximately 15 MPG in the city. How many miles should you be able to drive? = 150 miles
Emission System
Catalytic Converter
Converts harmful gases into less harmful gases & water
Muffler - reduces noise. Louder sounds may indicate a hole in. Our muffler
Check emission system - CO ( may poison you), CO2, hydrocarbons, nitrogen oxides
Drive Train SystemOften covered in warranty
Engine
Transmission (low fluid level may produce jerky shifting)
Clutch
Drive shaft
Differential (allows 1 wheel to turn more slowly than another)
Transaxle
Drive axles
Universal joints
Ignition & Electrical System
Alternator- recharges the battery
Battery - strong acid (dangerous)- powers vehicle's starter, lights, computer assisted controls, electrical accessories. A dead battery (no sound when starting the engine)can be jump started with jumper cables - know the procedure for "jumping" a vehicle's battery
Lights - headlights, taillights, back up lights, turn signals. Should be replaced immediately when defective
Lubricating & Cooling Systems
Oil helps engine work efficiently by reducing friction and cleaning engine parts - warning light comes on - pull off road and shut engine
Cooling System
Cools engine - mixture of antifreeze & water
Provides heat to interior of car
Radiator - connected to the engine - holds the coolant
Thermostat - controls the amount of coolant needed
Maintaining Control Systems
Power Steering - makes steering easier
Master Cylinder (Brake System) - forces fluid to each wheel's brake cylinder and squeezes brake pads against the turning disk which causes the friction to slow the wheel
Parking Brake is a completely separate system - it should hold your vehicle on a hill
Preventative Maintenance(Care given to prevent trouble
later)
Includes:
Day-to-day care
Mileage-based-maintenance: Periodic servicing done after a certain number of miles - shown in manual
Warranty may be voided if maintenance schedules are not followed
Tires
Belted tires - improved strength, performance and mileage
Radial tires - gives best fuel mileage - strengthens tire, improved tread mileage, & traction
Air pressure in increases when warm, lowers when cool
Tires need to be rotated regularly, balanced (for even wear) and aligned (for longer life & more even wear of tire)
