5. ENGINE
An engine or motor is a machine designed to convert one form of energy
Into mechanical energy.
Combustion Chamber
Cylinder Head
Piston
Crankshaft
Camshaft
Valve train
Valves
Short-Block
Timing Belt, chain, gears

7. COOLING SYSTEM
A vehicle’s engine-cooling system serves not just to keep the engine cool, but to also keep its temperature warm enough to ensure efficient, clean operation.
Radiator
Fan
Hoses
Thermostat
Water Jackets
Coolant
Water pump
Reserve Tank
215°F - 235°F

9. LUBRICATION SYSTEM
Designed to reduce friction between moving parts. By reducing friction, engine temperature drops, hence lowering wear on the moving parts.
Grease
Oil
Oil Pump
Oil Pan
Oil Filter
Oil Gauge
Oil Galleries

11. DRIVE-TRAIN
The drive-train of a motor vehicle is the group of components that deliver power to the driving wheels.
It varies the torque applied to the drive wheels, depending on load.
Transmission
Axles
Drive shaft
Differential

13. ELECTRICAL SYSTEM
Produces, stores, and distributes electricity for the numerous electrical devices which contributes to the operation of the total vehicle.
Stores Power - Battery
Produce Power -Alternator
Starter
Wiring Harness

15. FUEL SYSTEM
The function of the vehicle fuel system is to store and supply fuel to the engine.
Correct Air to Fuel ratio is 14.7 : 1 (Stoichiometric Ratio)
Four common fuels:
Petrol
Diesel
Propane (LPG)
Natural Gas (Compressed Natural Gas)
Fuel Pump
Fuel Filter
Injectors
Distributor
Carburetor
Regulator
Fuel Tank / Lines
ECM

17. EXHAUST / EMISSION SYSTEM
Removes the Exhaust gases from the engine, Muffles the sound, Cleans and cools the burned gases before they enter the atmosphere.
Headers / Exhaust manifold
Muffler
Catalytic Converter
Exhaust Pipes
Resonator

19. BRAKING SYSTEM
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction.
Converts kinetic Energy into Heat.
Wheel cylinder, Shoes, Drums – Rear
Caliper, Pads, Rotors – FRONT
Master Cylinder
Brake Fluid
Lines / Hoses

21. IGNITION SYSTEM
An ignition system generates a spark or heats an electrode to a high temperature to ignite a fuel-air mixture in spark ignition internal combustion engines oil-fired and gas-fired boilers, rocket engines, etc. Provides spark for the Patrol, CNG and LPG Engines.
Sparkplugs
Distributor
Sparkplug wires
Ignition Switch
Ignition Coil
Converts 12 volts
to 60,000 volts

23. STEERING SYSTEM
Steering is the collection of components, linkages, etc. which allows any vehicle (car, motorcycle, bicycle) to follow the desired course. The primary purpose of the steering system is to allow the driver to guide the vehicle(Controls the direction of the vehicle).
Steering Wheel
Steering Gear Box
Power steering Pump
Steering Linkage
Rack-and-pinion
Tie rod
Idler arm

25. SUSPENSION SYSTEM
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two.
Struts
Shocks
Springs
Control arms
Ball Joints
Knuckle
Damper
