If the details of your car and how it works fascinate you, then you want to read this post to the end. One such detail is your car’s fuel economy. Ever wondered why some cars consume so much gas while others don’t? Well, it all depends on the efficiency of the system that supplies the gas to the engine for combustion. Put more simply, it depends on the fuel injection system.
Fuel injection systems have gone through lots of changes over the years, and as technology advances, there’s bound to be more improvements. The following post describes the history of fuel injection and where we are at now:
What Are the Different Types of Fuel Injection?
Fuel injection systems vary greatly in design. Some older systems are no longer produced, and late-model vehicles use different types of fuel injection depending on their engineering design. Fuel injection slowly began replacing carburetors during the late 1970s and early 1980s, until carburetors were completely phased out of production vehicles by the early 1990s.
In this guide, the different types of fuel injection systems are explained, including the early designs from the ‘70s that have since been replaced by more efficient systems. Readers of the guide will obtain an understanding of the progression in design from early throttle body systems to the direct injection systems employed on many late-model vehicles. The guide also covers the maintenance requirements of current fuel injection systems, discussing services that can help keep fuel injectors performing at peak efficiency. Read more at eBay…
Interestingly, there are systems that no longer exist today. The cars that still use them are largely those that feature in antique competitions, attracting automobile lovers, and with huge cash prizes up for grabs.
Let’s focus on EFI engines, one of the common systems today. The following post explains it in detail:
What is EFI and how does it help my car?
EFI stands for ELECTRONIC FUEL INJECTION
The Electronic Fuel Injection system fitted to most modern vehicles combines sophisticated computer controls with a high-pressure fuel delivery system to provide optimum power and fuel efficiency. The system is controlled by an electronic control unit (ECU).
These systems often have anything in excess of thirty different engine and emission sensors all sending information continually to the ECU.
The ECU then monitors the information from the sensors and ensures the correct amount of fuel and air is used to provide optimum fuel efficiency and performance and also minimise exhaust emissions. Read more at Motoring About...
EFI engines are now used in most vehicles because of the efficiency they offer and their eco-friendliness.
How does an EFI engine compare with other common fuel injection systems? The following post answers that question brilliantly:
EFi Vs MPFi Vs GDi: How Electronic Fuel Injection Technology Works?
EFi, MPFi, GDi -
EFi stands for Electronic Fuel injection (EFi) whereas MPFi or MPi stands for Multi-Point Fuel injection and GDi stands for Gasoline Direct Injection. All these are the types of fuel injection systems which the gasoline or petrol fuel engines mainly use. All these terms refer to the newer generation Petrol Injection systems.
Earlier, older engines used simple Fuel Injection (Fi) which replaced the carburetor to overcome some of its shortcomings. The carburetor, being a mechanical device, was just not fully capable of controlling an accurate air-fuel ratio to meet the growing demands for better emission control. Read more at CarBikeTech...
