Engine Components and Operation The modern motor vehicle engine is a complex machine and power plant of the vehicle.
Engine Cooling System Technology The main function of the cooling system is to remove the heat from the engine, particularly around the cylinder walls and the combustion chambers. This should occur under all operating conditions, including the extremes of very hot weather, hard driving and high altitude.
Engine Lubrication System Technology All types of vehicle engines incorporate metal parts that have to rub against each other, thus causing friction which creates stress, wear and heat, e.g. cylinders in cylinder liners. These parts require lubrication to prevent the wear, keep the surfaces clean and help to remove the heat.
Fuel System Technology The fuel supply systems of petrol engine vehicles have been extensively developed over the last 50 years. The introduction of mechanical and electronic petrol injection systems has made carburettors almost obsolete.
Ignition System Technology The purpose of the ignition system is to supply a spark inside the cylinder, near the end of the compression stroke, to ignite the compressor charge or air/fuel vapour.
Body Electrical Systems This course will cover body electrical systems including washers, wipers, horns, obstacle avoidance and cruise control, mobile multimedia, seats, mirrors, roofs, central locking, security systems, starting control, and safety systems.
Electrical and Electronic Principles When a current flows in a circuit, it can produce only three effects – heat, magnetic and chemical. The heating effect is the basis of electrical components such as lights and heater plugs. The magnetic effect is the basis of relays and motors and generators.
Engine Electrical Systems A good supply of electric power is necessary for modern vehicles. Many components, that were once mechanically operated, are now driven by small electric motors and controlled by microprocessors.
Heating, Ventilation and Air Conditioning Fresh air helps to keep the driver of a vehicle alert. Most cars now allow a wide range of settings for ventilation.
Lighting and Indicators Vehicle lighting systems are very important, particularly where road safety is concerned. If headlights were suddenly to fail at night and at high speed, the result could be serious.
Monitoring and Instrumentation This course will cover monitoring and instrumentation including sensors, gauges, instrument displays, vehicle conditioning monitoring, digital instrumentation systems, global positioning systems, and drowsiness detection.
Multiplexing and Controller Area Networks The number of vehicle components which are networked has considerably increased the requirements for the vehicle control systems to communicate with one another. The CAN (Controller Area Network), developed by Bosch, is today’s communication standard in modern cars.
