IGNITION SYSTEM IGNITION SYSTEM opyright Gautam Malik 2007
IGNITION SYSTEM opyright Gautam Malik 2007 IGNITION FUNTION Produces 15000-30,000 volt spark across spark plug Distributes high voltage spark to each spark plug in correct sequence Times the spark so it occurs as piston is nearing top dead center Varies spark timing with load, speed, and other conditions
IGNITION SYSTEM opyright Gautam Malik 2007 BASI IGNITION SYSTEM OMPONENTS BATTERY/ MAGNETO IGNITION SWITH IGNITION OIL DISTRIBUTOR SPARK PLUG IGNITION SYSTEM WIRES
IGNITION SYSTEM opyright Gautam Malik 2007 BASI IGNITION SYSTEM Battery supplies power to entire system Ignition Switch turns engine on or off oil transforms volts Switching device triggers ignition coil Spark Plug and wires distribute spark
IGNITION SYSTEM opyright Gautam Malik 2007 PRIMARY IRUIT onsists of low voltage wiring and components Uses conventional type automotive primary wires ontrols when ignition will take place. (When coil fires)
IGNITION SYSTEM opyright Gautam Malik 2007 SEONDARY IRUIT Distributes current to individual cylinders to jump spark plug gap Must have thicker, heavier insulation on wires Typical voltage to jump gap - 10K Volts
IGNITION SYSTEM opyright Gautam Malik 2007 IGNITION OIL TRANSFORMER 2 SETS OF WINDINGS Primary windings Secondary windings IRON ORE PRODUES MAGNETI FIELD
Anatomy IGNITION SYSTEM opyright Gautam Malik 2007
Distributor IGNITION SYSTEM opyright Gautam Malik 2007
IGNITION SYSTEM opyright Gautam Malik 2007 ondenser It acts like a capacitor in the ignition circuit.it gets charges when there is no spark & discharge itselfs so as to make the spark possible
IGNITION SYSTEM opyright Gautam Malik 2007 IGNITION SYSTEM TYPES ONTAT POINT IGNITION SYSTEM ELETRONI IGNITION SYSTEM DISTRIBUTORLESS IGNITION SYSTEM
IGNITION SYSTEM opyright Gautam Malik 2007 ONTAT POINT SYSTEM Distributor turns 1/2 engine rpm Distributor am ontact Points ondenser Point Dwell (am angle) Basis for all Systems
IGNITION SYSTEM opyright Gautam Malik 2007 DWELL (AM ANGLE) Amount of time in distributor degrees that points remain closed between each opening oil saturation time is controlled by amount of dwell
IGNITION SYSTEM opyright Gautam Malik 2007 ELETRONI IGNITION Uses electronic control circuit to operate the ignition coil More dependable than contact system Higher secondary Ignition voltages SYSTEM
IGNITION SYSTEM opyright Gautam Malik 2007 MAGNETI PIK UP OIL Produces tiny voltage pulses to create magnetic field changes Trigger Wheel interrupts magnetic field Tell control unit (amplifier) when to fire ignition coil
IGNITION SYSTEM opyright Gautam Malik 2007 HALL EFFET DEVIE Hall Effect element is a solid state device ontains a permanent magnet next to element A Tab shunts magnetic field to send signal to control unit Signal is On or Off
IGNITION SYSTEM opyright Gautam Malik 2007 IGNITION ONTROL UNIT AMPLIFIER ontrols Primary current to tell Ignition oil when to fire spark plugs
