Since they’ve been around for so long, carburetors were very cheap to manufacture and easy to install in cheap cars. The last car to have a carburetor was an Isuzu pickup from 1994; it switched to fuel injection in 1995 .
Do any modern cars have carburetors?
All production vehicles today use computerized fuel injection systems to feed fuel and air into the combustion chamber of the engine. ... After that, you have to let the engine warm up. Otherwise, it simply won’t run right. Carburetors on cars operated the same way .
When did fuel injection replace carburetors?

Are carbureted engines good?
The carburetor contains jets that will push the gas into the combustion chambers. ... 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.
Which is better carburetor or EFI?
Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. ... EFI performs well over 2,000 rpm or more. On average, if optimized, both systems perform about the same as far as how fast you get down the track. However, the EFI system is much easier to tune than a carburetor.
Which gives more mileage carburetor or fuel injection?
Which gives more mileage carburetor or fuel injection? Fuel injection system makes complex calculations which include fuel temperature, throttle response, etc to ensure the right amount of fuel is injected into the combustion chamber. This way the use of fuel is a lot more effective resulting in better mileage.
Can you replace carburetor with fuel injection?
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.
Why did old cars have a choke?
When it comes to running engines the only things old cars have in common with new ones is that they all need spark and fuel delivery. ...

What is the difference between a fuel injected and carbureted engine?
Unlike carburetors, a Fuel Injection system is comprised of a complex set of electronics and sensors. In carbureted systems the fuel gets drawn from the tank , while in a Fuel Injected system it depends on a fuel pump installed inside the tank for a fine-grained control over fuel flow.
