What is the ignition system of a car?
Let’s consider what its peculiarity is, on what principle it works, and what varieties are. The ignition system of a car with a gasoline engine is an electrical circuit with many different elements on which the operation of the entire power unit depends.
Where does the ignition take place in an I.C engine?
The ignition system is one of the most important systems used in the I.C engines. The spark-ignition engine requires some device to ignite the compressed air-fuel mixture. The ignition takes place inside the cylinder at the end of the compression stroke, the ignition system serves this purpose.
What happens if the ignition system is not working?
The ignition system is responsible for igniting fuel in the engine’s combustion chamber. If the system isn’t working correctly, the engine will misfire on one or more cylinders. Generally, only one cylinder is affected, but this isn’t necessarily always the case.
What is the purpose of the distributorless ignition system?
4. The Distributorless Ignition system (from 1980s to today) The purpose of the ignition system is to create a spark that will ignite the fuel-air mixture in the cylinder of an engine. It must do this at exactly the right instant and do it at the rate of up to several thousand times per minute for each cylinder in the engine.
What are the different types of ignition systems?
Failure of ignition system components can lead to poor fuel economy, rough idle, and engine misfires. Currently, there are three distinct types of ignition systems, The Mechanical Ignition System was used prior to 1975. It was mechanical and electrical and used no electronics.
How does an ignition system work in a car?
Using engine sensors to determine crankshaft position and sometimes camshaft position, an Electronic Control Unit triggers the appropriate ignition coil and directs the distribution of electrical current to the spark plugs. The trick behind this system is the use of “waste spark” for one of the paired cylinders.
What should I look for in an ignition system?
Inspect the ignition system related switches for correct continuity according to the service manual or wiring diagram. This usually includes the main (ignition) switch, engine stop switch, and side stand switch. Other switches involved may be gear position/neutral, reverse override, tip-over, and other ignition based safety switches.
What are the advantages and disadvantages of an ignition system?
Advantages: It’s relatively easy to diagnose and repair. Disadvantages: It contains many moving parts and requires frequent maintenance. Breaker point deterioration cannot provide maximum spark energy for every spark event throughout the life of the engine (frequent misfires are possible, increasing emissions).
