We live in a generation where people are lazy and so
dependent on modern conveniences. We can not even be bothered anymore to push
buttons on a machine to get results. In our day and age everything is touch-sensitive
– no need to push the button, just touch the screen and get results! We also
have remote controls for every type of electric gadget including light
switches, music players, TV, car engines, fans, and A/C and heating systems to
name a few.
Part of this laziness is that we also don’t rely on
our feet to take us around and take us to places. We instead rely on wheels. If
it will be a bicycle wheel or even a roller blade wheel it will be good. But
not. We rely on motorized wheels. Be it a motorcycle or a car, we want to
quickly and efficiently bring ourselves to where we need to go with the
smallest effort possible.
From all the motorized wheels available to us, most
people like their own personal car best. We like the privacy and convenience of
having a car at our beck and call. No longer do we like to rely on taxis,
trains, buses or even a friendly hitch. We want to have a car parked right
outside in our driveway or in front of our house or apartment building, waiting
patiently for the minute we decide it’s time to make use of it. No matter the
distance, be it close or far, intricacy or intercity, our private car gets us
to where we need and want to go and at the exact time that we want to. We get
into our car to drive down the block or around the corner. Many of us would
even dig our car out … Read more
To follow fuel and emissions standards, the fuel
system currently used in modern cars has changed completely over the years.
Even the last car sold in the United States has a Subaru Justy carburetor.
Since then, all new cars have been working with fuel injection. Although fuel
injection systems have existed since 2019, they are not often used until
extensive use in European vehicles begins. At present, all cars sold in the US
have a fuel injection system in their parts inventory.
Fuel Injection Systems
The internal combustion engine for most of its
existence had been supplied with fuel by the carburetor and on smaller engines
it still is. But with car engines becoming more and more complex to meet
emissions requirements that had become stricter and stricter, the catalytic
converter was introduced. But this auto part needed very close control of the
air-to-fuel ratio to work effectively. O2 sensors or oxygen sensors were put in
to observe the oxygen amount in the exhaust and another auto part called the
“engine control unit” would then take this information making any
real-time adjustments to the air-to-fuel ratio. But this system did not
maintain control of the carburetor properly as the O2 sensors often needed
replacing nor did electrically controlled carburetors so another means had to
be developed to manage this problem. That’s when the fuel injection system
began to be used in cars.
Initially, the single point injection system replaced
the carburetor. But slowly when a new and more powerful engine was developed,
one point was replaced by a “multi-port” injection.
In these systems, each cylinder has an individual fuel
injector that sprays fuel right on the intake point and these systems offer
much more precise fuel metering and fuel reaction.
