Vehicle ignition system and efficiency in driving

Vehicle ignition system is one of the major systems of the vehicle technology.
Today we're going to learn how new model cars become more efficient, more safe and more portable than those of old models.

One of those great features  that made you love new model vehicles more than old ones is the Ignition system.  

Cars before now hardly worked consecutively for three months without a mechanic resetting  the contact point, replacing the condenser or at times fighting the jerky motions.
Most new model vehicles recognised and improved that technology for greater convenience, and your overall safety on the road.

Today you can just wake up and begin to pour water on your Engine compartment, wash it cleaner and start the vehicle on the go, without headaches.
 Because of the complicated nature of the old ignition system, you'll only wash Engine with fuel, carefully cover it before attempting to pour water on the engine compartment. 

Today with your vehicle, you'll easily navigate through flood confidently.  The improved new model Ignition system made this very possible.

Two major types of ignition system

The first type is distributor ignition system, this in turn, is divided into two types:

  1. Battery, coil and contact  point ignition system. This system uses the  combination of battery, primary and secondary windings of the coil and contact breaker poi
    nt to generate a spark needed to initiate a combustion in the Engine.

What's the technology behind this?

When you turn on the ignition key, battery will produce the primary voltage of about 12 volts, which routes directly into the primary windings of the coil, as shown on the diagram. This voltage is routed to the condenser, which charges it up.

On cranking the engine, the cam lobe of the distributor will turn and separate the moving butterfly plate from the ground plate of the distributor. This will break the circuit and destroy the magnetic flux generated.

The condenser, being charged up will discharge into the secondary windings of the coil. This voltage is about 1000X that of the primary windings, and sufficient to jump across the gap of the rotor and points on the distributor cover, and the spark plug gaps. This is perceived as the sparks that initiate a combustion in the combustion chamber.

Observe the following instructions while using this system

While washing your engine, use fuel,  and ensure it dries up completely before attempting to start the Engine as this system usually suffers sparks leakages, so you'll not set your Engine ablaze.

Make sure you cover the distributor well before trying to use water to wash the Engine compartment.

And always make sure you replace the condenser and contact breaker point at frequent interval to avoid emergency breakdown due to wears and extreme voltage

If you're still using this system, please don't joke with your fire extinguisher. There's always a spark leakage in this type of ignition system, to safe yourself and your car in case of emergency.

2. Another type in this category is electronic distributor ignition system
This is the same as contact point type except, the contact breaker system is replaced by ICM ( ignition control module).  This is more advanced and saver compared to the first type.

Another major type of the ignition system is the distributorless ignition system. It completely eliminates the need for a distributor.  Most new model vehicles use this system, for efficiency, comfort, more fuel economy and greater emission control. This system ensure timely ignition of the air/fuel mixture than the old system.

Technology behind distributorless ignition system

We're singing the same song in different terms. What we're after in ignition system is to generate a spark that will initiate  burning of the mixture of air and fuel. So if it's safe to use a lightning match, no wahala.

So what happens in the distributorless ignition system?

This system uses triggering devices ( timing plate), electronic control module (brain box) and ignition control module (ICM). 
The triggering devices are mounted on both crankshaft and camshaft, then crankshaft position sensor (CKP) and camshaft position sensor (CMP) are mounted on the block Engine and cylinder head respectively  to monitor the rotational speed of the triggering plates, the voltage generated is communicated to the brain box, signalling it about the position of the piston and which cylinder needs a spark at the moment. This information, tells the brain box to signal the ignition control module, consisting of coil packs, to fire a cylinder that's ready for combustion.

The advantage of distributorless ignition system over distributor ignition system

1. It's safe, more timely Ignition, complete mixture burning and enhances emission control.
2. Confidence to drive the vehicle, in snowy and flooded environment
3. Less fire hazard, as spark leaks is not common
4. Enhances vehicle tune up interval and services, 
5. It easily detects knocks and retard ignition in time.

Two types of distributorless ignition system

  1. Waste spark system: this system uses one coil to fire two cylinder at once. A two points coil is connected to two cylinders that are 180 degree apart, that's when one is on power stroke, the other is on exhaust stroke, so that spark on the  exhaust gas will have no effect. Sienna 2002 model, Chrysler, ford, and Dodge 2000-2003 model use this method. It's mostly found on multi cylinder engines, like v-6, v-8 .
  2. Another type is coil over plug ignition system: this has individual coil over a spark plug, it's the most recent types that all the latest vehicles are using. It's very very effective.
Ignition system is the pivot of every vehicle, that's why, the first question to ask in no start condition of every vehicle is, " e dey spark?" Or "light dey come?", If there's fuel in the system. 

When you're having difficulty starting your Engine, it's important to have your ignition system diagnosed by a specialist.
