Carburetor vs Fuel Injection – A Short History and Pros & Cons
Jan 15, · Disconnect the throttle (and kickdown if equipped) linkage from the carburetor and set these out of your way. Disconnect the fuel supply and stopper it to keep it from leaking. Remove the 4 ?-inch nuts securing the carburetor to the intake. Carefully lift the carburetor off and set it in a container to drain. Jul 02, · Take off the fuel lines and hoses that come from the carburetor. The carburetor is mounted to the manifold by nuts. Use a wrench to remove these and take the carburetor off. If it is in good shape, it's possible to sell it as a used part; if not, then it can go to a junk yard.
A fuel injection conversion replaces a carburetor with a fuel injection system. There are fuel injection conversion kits that make the entire process very easy. Older cars have carburetors, but electronic fuel injection EFI offers greater fuel efficiency and improved performance. The carburetor is mounted swittch the manifold by nuts.
Use a wrench to remove these and take the carburetor off. If it is in good shape, it's possible to sell it as a used part; if not, then it can go to a junk yard.
Install the Injectors in the Intake Manifold Injectors need to be installed into the intake manifold. Welding will be involved, so it may be necessary to bring the vehicle carburrtor part to a machine shop. Most intakes can be modified using weld in bungs for injectors. Once the injector spot is available, the injectors slide into place and with o-rings for the seal. Injection fuel rails are also necessary, but these need to be machined. Depending on the type of conversion kit, it may come with a ready-to-go manifold that accepts injectors.
Many companies also produce ready to go injector manifolds. Install the Throttle Body The froj body regulates the air going into the valves. Universal models are the easiest for conversions. Bolt the throttle body on and hook it up at the throttle linkage. This is connected to the accelerator pedal. An idle air controller is needed with the EFI throttle body.
This goes into a small passage that pushes extra air past the throttle plates. It opens or closes the passage depending on how much air is needed in the manifold. Most throttle bodies come with an IAC already installed. Install the Sensors In order for the EFI system to monitor and change the injection, several measurements need to be taken.
If they're not already in place, several sensors need to be installed. An oxygen sensor, manifold air pressure sensor, air temperature sensor, coolant sensor and throttle position sensor are needed. These are fairly easy to install, as most easily screw into the engine. The kit should contain everything you need. If not, there are sensor packages available. Adjust the Distributer Because the new EFI system controls the timing and advance of the ignition, these will need carnuretor be locked out of the distributor.
The vacuum and mechanical advance also need to be locked out. Most distributors will be fine with a bank-to-bank EFI system. If sequential fuel injection is used, then a dual sync distributor maybe needed. The easiest way to install one is to get an aftermarket system, because it's very difficult to reprogram a factory control unit. Larry hagman cancer what kind of the necessary components are programmed in and by connecting the computer to a laptop you can customize the different settings.
Most of the systems will simply need to be mounted and plugged in using a wiring harness. Once you have tuned everything to the desired acrburetor, the vehicle is all ready to go. If you have to replace the old fuel injection regulatorread the following. First find out the exact make and model of the car that you are repairing.
It will mention the exact kind and variety of injecction pressure injection system that is used. Then you carbureto check with online what will i get for social security part websites to find the right part.
Stick to the brand that is mentioned in the owners manual to get the how to buy a zippo fit and performance. You can replace a fuel injection if it becomes faulty. The process is simple and there are many video tutorials present online that you can take a look at to learn the process.
Make sure that you also read the Owners manual of your car to find the right spare parts. Just ensure that you have the relevant technical expertise to work with cars before proceeding.

How To Do The Conversion From Carburetor to Fuel Injection
Jul 13, · Attach the power and ground wires to the fuel pump using solderless connectors. Connect the main power to the relay to the junction block/fuse panel or the battery, and the relay ground to a good ground or the battery. The switching lead needs to come from a switched source that is on when the engine is starting and running. Jul 09, · The best way to convert a carburetor to fuel injection on a dirt bike is to use an electronic Fuel Injection or EFI kit. Once the right conversion kit is identified and you have all the right parts, get access to the carburetor, connect EFI to power, install the sensors, the Author: Louis Pretorius. A fuel injection conversion replaces a carburetor with a fuel injection system. There are fuel injection conversion kits that make the entire process very easy. Older cars have carburetors, but electronic fuel injection (EFI) offers greater fuel efficiency and improved performance.
To start any conversation on carburetor vs fuel injection, one has to think back to the very beginning of the internal combustion engine. Some of the first engines relied on a simple fuel drip, but better ways of introducing fuel into the cylinder would eventually come along. Early carburetors relied on air flowing over liquid fuel or a wick, gathering fuel vapors for ignition. Later versions would utilize the Bernoulli principle to better meter the amount of fuel going into the cylinders, that is, the air flowing through a venturi would deliver fuel in proportion to the amount of air going into the intake.
By the time the last carbureted vehicles in the US died out, in the early s, fuel injection was already in full force. Fuel injection as we know it actually has its roots as far back as the first engines, back in the s; however, its complexity prevented it from being utilized on any scale until the s, and it was still limited to compression-ignition diesel engines.
Later, in the mids fuel injection systems would appear on both diesel and gasoline engines, in both mechanical and electronic versions. The first electronic fuel injection systems, using a throttle-body injector, simply replaced the carburetor.
Port fuel injection placed individual fuel injectors closer to each intake valve, which powers the majority of modern automobiles. Later, similar to diesel engines, some gasoline engines would be fitted with direct fuel injection, which puts fuel directly into the cylinder. Some direct fuel injection systems co-exist with port fuel injection systems.
While the carburetor may have been around for over a century, fuel injection is a clearly superior alternative, delivering better power, fuel economy and lower emissions. For the modern driver, this is all you could ask for. Photo courtesy of Wikimedia Commons. Know How.
