Which Type of Fuel Injection Do Most New Vehicles Use

Posted by Susan California on July 21st, 2019

Fuel injection is used in internal combustion engines of different automotive vehicles and is done for the purpose of the engine to avoid fuel starvation. The fuel injection system aids in feeding fuel and air into the engine and there are two ways to inject fuel in the engine.

How Fuel Is Injected In The Combustion Engine?

Almost all types of common automotive engines such as diesel engine, petrol engines or other types use fuel injection in different systems. In fact, compared to carburetors the fuel injection system is more favored one in almost all types of vehicles; be it a new or ordinary one.

Fuel can be injected either electronically or manually in an engine.  Thereby, there happen to be two fuel injection systems for feeding the engine with fuel. And these are as follow-

1.        Electronic Fuel Injection
2.        Mechanical Fuel Injection

Advent Of Different Types Of Fuel Injection

The earliest types of fuel injection can be traced back to many, many years ago to replace the use of carburetor.

The more advanced type of fuel injection system is currently the best alternative to carburetors and is very crude by modern standard.

But, do you know the different types of fuel injection used in new vehicles? Do you also know the specific type which is mostly used in new vehicles?

Basic Types Of Fuel Injections That New Vehicles Use

To know the best fuel injection type used in new cars you’ll first have to know the basic types of fuel injection.

In fact, new cars and vehicles require four basic types of fuel injection and these are as follow- 

1.        TBI or Throttle Body Injection
2.        MPFI or Multipoint Port Fuel Injection
3.        SPFI or Sequential port fuel injection
4.        DIG or Direct injection Gasoline

The Type Of Fuel Injection Most Used In New Vehicles

Now that you know about the different types of fuel injection used in almost all types of vehicles there comes one important question. Which type of re-manufacturing diesel injectors do most new vehicles use? 

In fact, currently, new cars and companies are choosing to use both port and direct fuel injection to their engines.  It’s becoming increasingly common to see the new vehicle engines using both port and direct injection. Why? It is mainly because of the following advantages.

Advantages of Direct Fuel Injection

ü  Provides precise control over the injection point

ü  Larger quantity of fuel can be injected with higher injection pressure

ü  MPG and knock tolerance of the engine gets improved

ü  Provides better automization to the engine

Advantages of Port Fuel Injection

ü  Gas engines tend to end up with deposits in the intake valve and port fuel injection effectively cleans off the valve.

ü  Port fuel injection also cools down the intake valve during fuel vaporizations

ü  Engine performs smoother with improved mpg
