Any one is missing me? (o,O) NO matter my girlfriend still
with me, and as I remember we was talking about her kind Heart, sorry I mean
her engine.
Car simplification
what is car? Part 3
We was talking at “Part 2” about, what is engine and how is
simply working. Also, we discussed briefly how the fuel is entering the
chamber, two more things we need to talk about the 1st is (how to
ignite the fuel?) And the 2nd (how we start the engine?) so, let us
start.
How we can ignite the fuel?
There are two basic methods to ignite the fuel into internal
combustion engines:
1-
Self Ignition. (called
Diesel Engine)
2-
Using ignition system.
(Called Benzene Engine)
In fact this is one of the main differences
between Diesel and Benzene Engines. In addition to, power, speed, and size. But
we will discuss the differences later.
-
* Based on pressure and
temperature relations when we increase the pressure the temperature increases
too. That’s why we use gasoline as a fuel for Diesel engine.
* When the pressure of the
gasoline increase, the gasoline will be fire at (about 250 deg. C) without any
ignition spark. This temperature called (Self Ignition Temperature).
 |
| Ignition System with Distributor. |
* The benzene could not be self ignited,
because it’s need about three times gasoline pressure to be self ignited which
is extremely hard to be achieved (about 550 deg. C)
* Spark-plug with spark Distributor
is needed to firing the fuel at Benzene engines, with certain firing order. But
some cars distributor-less or it electronically distributes the sparks to the
spark-plugs.
 |
| Distributor-Less Ignition system |
* A spark is a highly voltage
charge runs through a wire connected to the spark-plug.
*As conclusion if u r using
diesel engine, you don’t have ignition system. But if you have benzene engine
you may have distributor or distributor-less ignition system.
But how the engine start, this will be our
next part, Go check part 4
