Electrical System 1.Ignition systems 2.Starting systems 3.Charging systems 4.Lighting systems

Ignition System System for igniting the fuel mixture Breaker point(1910- early1970) Electronic( ) Distributorless(1980-now)

Starting System Power source used to provide the initial rotation to start large gas turbine engine

charging system Replace electrical energy drawn from the battery during system starting operation

lighting system Consists of the components that operate a vehicle’s interior and exterior lights ( fuses, wires, switches, relays, etc.)

Engine Systems 1.Exhaust Systems 2.Cooling Systems 3.Lubrication System 4.Diesel injection Systems 5.Fuel injection systems 6.Emission Control Systems 7.Carburetor Fuel Systems

Engine types

Exhaust System Used to guide exhaust gases away from a controlled combustion inside an engine

Cooling System Maintains a constant engine operating temperature. There are two major types of cooling systems. Air cooling system Liquid cooling system

Lubrication System Reduces friction and wear between internal engine parts by circulating filtered engine oil to high- friction points in the engine

Diesel Injection System High pressure mechanical pump spray fuel directly into combustion chamber

Fuel injection system Primarily a mechanical system that forces diesel fuel(not gasoline) directly into the combustion chamber(1990-now) TBI (Throttle Body inj.) mid MPI (Multi-port inj.)mid 1990-now

Carbureted fuel System Uses engine vacuum (suction) to draw fuel to the engine

Emission control system Used to reduce the amount of toxic(poisonous) substances produced by an engine

Chassis system Brake system Drivetrain system Steering system Front suspension Rear suspension

Chassis

Brake System Produces friction to slow or stop the vehicle

Drive Train System Transfers turning force from the engine crankshaft to the drive wheels

Steering System Allows the driver to control vehicle direction by turning the wheel right or left

Front Suspension Vehicles do not have a driveshaft or a rear drive axle assembly. The complete drive train is in the front of the vehicle

Rear Suspension The drive shafts sends power to the rear axle assembly. The rear axle assembly contains the differential and two axles that turn the rear drive wheels. Drive train and suspension interact.

Miscellaneous Systems 1.Computer System 2.Accessory System 3.Safety System

Computer System Uses electronic and electrical devices to monitor and control various systems in the vehicle, including the fuel, ignition, drive train, safety, and security system

Accessory System Includes the air conditioner, sound system, power seats, power windows, and rear window de-fogger

Safety System Includes seat-belts, air- bags, and security systems various safety systems are used on modern vehicles to protect both the driver and the passenger.
