As some would agree, an automotive engine is a complex masterpiece. There are many components that function to support the engine's performance. One main part that ties everything together is the ignition system. The vehicle's starting circuit functions on about 10 different parts to create a spark for the engine to start. Some may think of the ignition as just a spot to place the key in and start the vehicle, but it is actually very complex.
A vehicle's ignition circuit consists of the ignition coil, distributor, distributor cap, rotor, plug wires, and spark plugs. There are two sides to the vehicles ignition system: primary and secondary. The primary side deals with voltage from the battery. The secondary side is how the spark gets delivered to the spark plugs. The systems ignition coil is the leader in the process of starting your engine. The coil takes the car's battery power and turns it into a spark. After the ignition coil has created enough spark, it sends it to the distributor. The distributor can then send the spark to each spark plug through the spark plug wires. The spark on each plug then ignites the fuel and air mixture to start the engine. The invention of the electronic ignition circuit came about to solve emissions and reliability issues from the previous point-type ignition system. These two ignition systems are separated by just a few parts. Automotive ignitions today, however, are being manufactured without distributors. This increases the length of time needed for a tune-up. The vehicle's engine control unit has full control on spark timing in this ignition setup which can increase the engine's output. Some vehicles today do not need their first tune-up until 100,000 miles. Not having to replace the distributor cap and no need for spark plug wires are the other advantages to this setup.
Maintaining the vehicle's ignition system is a must. With having to start the car frequently, these components take everyday abuse. Ensuring that this process works without a hitch, frequent tune ups could be necessary. The distributor cap and rotor play such an important role in delivering the spark to the spark plugs. If the rotor is worn or damaged, it can cause the vehicle to run improperly and even stall out. Through daily use, contacts inside the circuit's distributor cap will eventually become worn and dirty. These contacts must be clean in order to deliver the right amount of spark. A car's engine that misfires or stalls is a typical sign of a bad or worn distributor cap.
Upgrading the way a vehicle gets its spark to start the engine is an option many like to take. With the way aftermarket ignition circuits are made now a days, they offer less maintenance, higher efficiency and more pep from the throttle. When upgrading to an aftermarket automotive ignition system, voltage efficiency can sometimes be increased by 50 percent. This means that the spark plugs will benefit from a hotter and more powerful spark from the distributor. Having more voltage flow through the system will require an upgrade to the spark plug wires as well. The factory spark plug wires can only handle voltage offered from the stock ignition system. A larger spark plug wire will be much more capable of carrying the load. Adding a set of premium spark plug wires from Magnecor will provide excellent heat protection for any race or heavily modified vehicle. Ignition spark plug wires also come in various colors to accent the engine area. Magnecor has been in the automotive industry for many years with many people trusting their products. Full aftermarket tune-up kits are available and usually include cap, rotor, plug wires, and spark plugs.
An upgrade for many enthusiasts is using a multi spark discharge box, or MSD. Instead of just one spark, these ignition boxes create additional sparks. The factory starting system can sometimes run into problems when adding performance parts. MSD is offered in a variety of street and race applications depending on the user's goal. A good set of aftermarket high performance ignition spark plugs from NGK or Nology could improve fuel efficiency with lower emissions and longer lasting. Most aftermarket automotive spark plugs have a lower engine misfire rate than factory ones. For high performance engines, a set of aftermarket fuel injectors will provide the engine with quicker delivery of fuel resulting in more horsepower. These upgraded injectors can sometimes increase fuel delivery by 10 percent and reduce emissions. Automotive engines with superchargers or turbocharges utilize performance fuel injectors to keep up with the forced induction.
