Explanation: The main advantage of fuel injection in SI engine is increased volumetric efficiency.
What are the advantages of fuel injection system in SI engines?
Fuel injection allows precise fuel metering, which increases efficiency. Maintaining a stoichiometric is necessary for the operation of a three-way catalyst, which destructs most of the harmful emissions. In regions where quality fuel is used, there are rarely any clogging or other problems.
What are the advantages of fuel injection?
The Benefits of Electronic Fuel Injection
- More Power. EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. …
- Lower Fuel Consumption and Emissions. …
- Increased Reliability. …
- Less Maintenance, Less Downtime. …
- Improved Starting.
What is the disadvantage of fuel injection?
Disadvantages of Fuel Injected Engine
Fuel injection system is a complex electronic controlled device that related and connected with few electronic sensors and complex engine control unit. Its maintenance or repair scope is very limited and not possible in regular workshop. The whole system is quite expensive.

Is fuel injector used in CI engine?
The injection pump sends fuel under pressure to the nozzle pipes which carry fuel to the injector nozzles located in each cylinder head. … CI engines are operated unthrottled, with engine speed and power controlled by the amount of fuel injected during each cycle.
Which is better carburetor or fuel injection?
So with a carburetor, the best fuel to air ratio for each cylinder is approximated for the best performance. However, carburetors do last longer than fuel injection systems and are favored in motor sports. … The carburetor is currently much less expensive than the electronic fuel injection systems.
Does fuel injection increase horsepower?
Larger throttle body and injectors
Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque. There is a catch, however. … Also remember that a larger throttle requires higher-flow fuel injectors. Throttle body and injector size are proportional.
Which is more fuel efficient carburetor or fuel injection?
A fuel injection system precisely delivers fuel in the right amount and can tweak it according to several parameters resulting is less fuel wastage and better fuel efficiency. A carburettor is unable to adjust the fuel ratio according to the engine conditions.
How much more efficient is fuel injection?
This is approximately a 50% increase in fuel efficiency in a gasoline engine. The fuel injection system was developed by a startup company Transonic Combustion and their goal is to increase fuel efficiency of existing gasoline engines.
What are the types of fuel injection system?
What Are The Different Types of Fuel Injection?
- Single-point or throttle body injection.
- Port or multipoint fuel injection.
- Sequential fuel injection.
- Direct injection.
What are the signs of a bad fuel injector?
Here are a few signs there might be something wrong with your fuel injectors.
- The Engine Misfires. Dirty fuel injectors may cause your vehicle’s engine to misfire. …
- Idling Gets Rough. …
- Your Gas Mileage Tanks. …
- The RPM Needle Starts to Dance. …
- Your Car Won’t Start.
Why carburetors are better than fuel injection?
Though they are easier to start, carbureted engines are less efficient during flight. Since the fuel/air mixture in carbureted systems meet at the carburetor, the mixture is less precise for each cylinder. Fuel injectors are calibrated to force the same amount of fuel into each cylinder.
What are three types of fuel injection systems?
The three major types of fuel injection are known as throttle body injection, multiport injection, and direct injection.
