How Long Does A Head Injury To Show?
ELECTRONIC IGNITION SYSTEM ON CONVENTIONAL
In an engine (Otto cycle) with conventional ignition system, spark plug needs a voltage (voltage) that is between 8,000 to 15,000 volts (8 ... 15 kV), to produce the spark. This voltage depends on many factors, including:
wear plugs (opening of the electrodes).
resistance ignition wires.
distributor rotor resistance.
Distance between the high voltage output terminals of the rotor and distributor cap.
Flash Point (motor time).
compression cylinders.
air / fuel mixture.
engine temperature.
are among the most mechanics some confusion in regard to the tension generated by the coil.
Many think that the more powerful outside the coil, the greater the spark. Big mistake!
In fact, the coil is not "sending" the energy you want, and if it is the ignition system that requests (needs).
This request
energy (demand ignition voltage) depends on the items mentioned above.
The ignition system consists of:
Battery
Ignition Switch (switch)
Coil
Distributor
Power Cables
Spark Power

Before knowing the differences between ignition systems and coils, it is important you know as it generates high voltage necessary to produce the spark.
As we know, the voltage of 12 V supplied by the battery is not sufficient to produce the spark at the spark plug, so that tension should be increased until it reaches a sufficient value for "jump" spark between the electrodes.
This increased tension is achieved through the ignition coil, which is only a "transformer", which receives a low battery voltage and high voltage becomes necessary to spark production.

AUTOMOTIVE AUTOMOTIVE COOLING SYSTEM CHASSIS
Most cars in regular use , using water (coolant) in your system cooling
HISTORY: Formerly it was only to cool the motor, for this reason, there are still vehicles that use a fan (fan) fixed to the engine speed, do not use the thermostat, and also use a enough capacity radiator
Today, the concept is quite different. Now the engine is required to maintain a temperature above 180 degrees. F. The idea is that when hotter the engine, take a gaseous fuel, for which you require, that the air / fuel mixture entering the combustion chamber, stays hot, that way it is intended that the residual contaminants are low.
This means, that our car runs on the boundary of a heat problem (overheating) ... For this reason, we put great care and servicing of its components:
