Carburetor vs Fuel Injection

How to fuel injection is better than a carburetor

The carburetor and fuel injection are used as an Internal Combustion Engine. The internal combustion engine of the early years used a simple fuel drip system that although did the job, resulted in fuel wastage and poor fuel mileage. Fuel Injection or MPFI system.

In the automobile industry, starting-time carburetors has used cars, motorcycles, planes, etc. That a carburetor is a simple and effective fuel induction method.

The carburetor works at an air and fuel mixture or supplies the engine will run, But the MPFI or multi-point fuel injection system is a system or method of injecting fuel into internal combustion engines through multiple ports situated on the intake valve of each cylinder. It delivers an exact quantity of fuel in each cylinder at the right time.

Carburetor history and working system

The first carburetor was invented by Samuel Moey in 1826, A carburetor was among the early patents by Karl Benz (1888) as he developed internal combustion engines and their components on January 29, 1886, and Karl Benz is the founder of Mercedes Benz.

The carburetor works on the vacuum fuel method that means engine piston suction time carburetor is working the suck the air in the atmosphere to be used as a filter and fuel can be sucked into the fuel tank at the same time to both air and fuel or mixture in the carburetor and supply the engine.

The many movable components are used in the carburetor they are a throttle valve and choke valve another name is the butterfly valve the major component used in the carburetor and mileage and power also reduced, If you want the power to adjust the throttle valve but the mileage is reduced.

MPFI Fuel Injection System history and working system

The first MPFI system was developed by Herbert Akroyd Stuart. The first use of direct gasoline injection was on the Hesselman engine invented by Swedish engineer Jonas Hesselman in 1925. One of the first commercial gasoline injection systems was developed by BOSCH and introduced in 1952 on the Gorath GP700 and Gutbrod Superior 600.

The MPFI (Multi-Point Fuel Injection) system works on electronic fuel injection is consists of fuel injection supply sensors using an oxygen sensor, fuel sensor, Throttle position sensor, Intake air position sensor, engine coolant temperature sensor, vehicle speed sensor, crankshaft position sensor, camshaft position sensor, manifold pressure sensor with respect the engine speed, the system charges the fuel mixture, where higher speed engines require more fuel and low speed requires less fuel.

The Multi-Point fuel injection system makes the best option they will decrease vibration and help to overcome step grades and traditional terrain for off-roading. Airtex fuel delivery system is the leading aftermarket supplier of mechanical and electric fuel pumps and modular reservoir assemblies. The fuel pumps from Airtex have been the fuel delivery components. If you are looking for either an electric fuel pump or a mechanical fuel pump.

Compare a carburetor vs fuel injection


The fuel injection system with an electronically controlled fuel induction can constantly, the fuel delivery to the cylinders delivering better performance. A carburetor is unable to measure the air-fuel ratio and the petrol-fuel ratio struggles with changing air pressure and fuel temperature.


The only parameter where a carburetor trumps over fuel injection. Carburetors are pretty simple to clean and rebuild. Fixing a fuel injection system requires professional intervention or even an expensive replacement.

Fuel Economy

The fuel injection system precisely delivers fuel in the right amount and can it according to several parameters resulting in less fuel wastage and better fuel efficiency. A carburetor is unable to adjust the fuel ratio according to the engine conditions.
