The complicated
sections of an automotive engine are very well known by auto experts, who can
always be consulted in case the performance of the vehicle is decreasing. But
there are cases when the fuel transfer isn’t smooth and the engine might face
issues. Not many people are aware of this fact and tend to shed a lot of money
for vehicle servicing.
It is essential
to know that engines combust a mixture of air and fuel inside their chambers so
as to move the pistons which develop the car’s forward and backwards motion. Once
this is achieved, the motion gets conveyed to the wheels, thereby, allowing the
car to move. The vital aspect in this whole process is the transfer of fuel to
the cylinders that majorly depends on the type of fuel injection system incorporated
in the vehicle. Hence, the performance of your car engine naturally depends on
the fuel injection setup.
Below mentioned
are the top four fuel injection variants that are highly recommended by
automotive professionals.
Throttle
Body Injection System
It can be termed
as the first versions of injection systems which were ever implemented in vehicles.
Before this, vehicles were dependent on the use of carburetor. The function of TBIs
is slightly similar to a carburetor. However, the operations of TBI are controlled
using an electronic computer fitted within the vehicle. Due to the presence of
this computer, the system receives more accuracy through the determination of
the exact amount of fuel required to be deposited in the engine. Hence, there
is less fuel wastage and the vehicle runs more powerfully.
Multi-Port
Fuel Injection System
Similar to how
their name sounds, multi-port fuel injection (MPFI) systems function with multiple
intake ports. To be precise, they are surely a step ahead from throttle body
injection systems that only comprise of a single port. The placement of MPFIs
involves mounting onto each port. The placement of these intake ports happens
right outside the engine cylinders. It is important to know that, with MPFI
systems each cylinder gets its own direct fuel spray. Therefore, for a
six-cylinder engine it would require six injection ports.
Sequential
Fuel Injection System
Although sequential
fuel injection systems are rated similar to MPFI, there is one prominent difference
which makes it a leading option across the automotive
fuel injection system market. Sequential or timed injection, activates
each nozzle separately at the adjusted time so as to ensure that all the fuel reaches
the intake valve. The main motive of this process is to reduce fuel wastage.
Furthermore, it delivers the most optimized ratio between fuel and air occurring
in the combustion chambers.
Direct
Injection System
The operations
of direct injection systems vary from other fuel injection systems since they
dodge the intake valves and effectively deposit fuel openly into the combustion
chamber of the cylinder. It is interesting to know that direct injection is
actively incorporated in diesel engines from the 1920s and has also been used
in gasoline aircrafts that took part in World War 2. Looking at the present
time, several performance vehicle producers like BMW and Audi have started to
implement direct injection systems across their vehicle segments.
