The main difference between carburetor engine and MPFI engine is how fuel is delivered into the cylinders. In this case, the carburettor engine is an old technology that mixes air and fuel mechanically. On the contrary, MPFI (Multi-Point Fuel Injection) is an advanced internal combustion engine that uses electronic fuel injectors to supply fuel into the cylinders.
Read on for a detailed breakdown of the MPFI engine vs carburetor engine.
What is an MPFI engine?
MPFI is an internal combustion engine that supplies the exact fuel amount directly into the cylinder via multiple ports using modern fuel injection technology. This is an advanced form of engine with enhanced performance.
What is carburettor?
A carburettor engine is an internal combustion engine that mixes air and fuel using a mechanical device before supplying it to the cylinders. The engine uses a simpler and older technology to mix fuel and air.
Difference between carburettor engine and MPFI engine
Here's a table with a clear MPFI engine vs carburetor difference.
|
Difference
|
Carburettor Engine
|
MPFI Engine
|
|
Fuel delivery
|
The device mixes air and fuel mechanically before supplying it to the engine cylinders.
|
MPFI systems use electronic fuel injectors to supply fuel into the cylinders by spraying it directly.
|
|
Mechanism
|
The carburettor uses a vacuum to take out fuel into the airstream.
|
The Engine Control Unit (ECU) guides the fuel injectors in adjusting fuel delivery depending on the engine’s conditions.
|
|
Nature
|
Carburettors are simple in design and, hence, easier to repair and maintain.
|
MPFI systems have quite complex designs and require more advanced repair and maintenance.
|
|
Air-fuel mixture
|
Carburettors have fixed and less specific air-fuel mixtures, hence less efficient and likely to have higher emissions.
|
MPFI systems have more specific control in their air-fuel mixture, hence improving fuel efficiency, with lower emissions.
|
|
Emissions
|
Carburettor engines generally produce more emissions than MPFI engines due to less complete combustion.
|
MPFI engines produce fewer emissions than carburet
tor engines due to more complete combustion.

MPFI engine vs carburetor engine difference: Which is best?
In comparing the carburetor engine vs. MPFI engine, the MPFI engines are considered best since they have better fuel efficiency than carburettor engines and enhanced performance in power output. The specific fuel delivery enables complete combustion, minimises fuel wastage and boosts acceleration.
Conclusion
The key MPFI engine vs. carburetor engine difference is how fuel is supplied to the engine's cylinders. Note that even with the best engine, you still need to insure your vehicle with a comprehensive car insurance policy that offers broad coverage for a wider range of risks. You also need to secure your trips with third party car insurance, which the law recommends. The policy financially safeguards you from the high costs of vehicle repairs, replacements, or legal fees resulting from road accidents, car theft, or other unpredicted events.
