What is the difference between a carburetor and throttle body?

A TBI system is similar to a carburetor in that one or two injectors are located in a central throttle body that supplies fuel to the engine through the intake manifold. Instead of using engine vacuum to siphon fuel through metering circuits as a carburetor does, fuel is sprayed into the manifold through the injectors.
A.

Can you have a carburetor and fuel injection?

Carbureted vs Fuel Injected. In carbureted engines, the fuel/air mixture meets in the carburetor. The mixture then goes to each cylinder through the air intakes. In the fuel injected engine, the fuel and air do not mix until they reach the cylinder.
  • Which one is better carburetor or fuel injection?

    If there was a carburetor for each cylinder then this would not be an issue. 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.
  • Do fuel injected bikes have carburetors?

    Even the retro-styled Honda CB1100, with its air-cooled engine, has a fuel-injection system, not carburetors. But, with pollution laws really starting to have teeth for motorcycles, the manufacturers used the finer control of the air/fuel mixture that's made possible by fuel injection to meet the letter of the law.
  • When did Ford switch to fuel injection?

    On the 5.0L engine fuel injection was optional in 1985 and the only thing offered in 1986. In 1987 the 4.9L had standard fuel injection and in 1988 the 5.8, and 7.5L followed suit. In 1988 all you could get was fuel injection. Your 1989 was the first model year with locking hubs and yes all '89s were fuel injected.
B.

Do any cars still use carburetors?

Carburetors on cars operated the same way. To start the car, you had to pull out the choke and let the engine warm up. Modern fuel injection systems don't require this warm-up period. There are some very obscure auto makers, primarily in Africa and Russia, who still build cars with carburetors.
  • What is meant by carburetion?

    Definition of carburetion. : the process of mixing (as in a carburetor) the vapor of a flammable hydrocarbon (such as gasoline) with air to form an explosive mixture especially for use in an internal-combustion engine.
  • When did fuel injection become common?

    It was introduced in the 1940s in large aircraft engines (then called the pressure carburetor) and in the 1980s in the automotive world (called Throttle-body Injection by General Motors, Central Fuel Injection by Ford, PGM-CARB by Honda, and EGI by Mazda).
  • Are carburetors still used in cars?

    The only cars they're still in use on is the older ones that haven't died yet. No new cars use carburetors as they offer no advantages over fuel injection. Fuel injection gives more mileage, better warm up characteristics, more power, less emissions, etc.
C.

What was used before fuel injection?

Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke. On petrol engines, fuel injection replaced carburetors from the 1980s onward.
  • What is the purpose of the fuel injector?

    Function of Diesel Fuel Injection. The fuel injection system lies at the very heart of the diesel engine. By pressurising and injecting the fuel, the system forces it into air that has been compressed to high pressure in the combustion chamber.
  • Do fuel injected bikes have carburetors?

    Even the retro-styled Honda CB1100, with its air-cooled engine, has a fuel-injection system, not carburetors. But, with pollution laws really starting to have teeth for motorcycles, the manufacturers used the finer control of the air/fuel mixture that's made possible by fuel injection to meet the letter of the law.
  • What does fuel injector cleaner do for your car?

    Clean the fuel system from the gas tank by adding a premium formula fuel system cleaner. Fuel injector cleaning or carburetor cleaning, intake valves, and combustion chambers with fuel system cleaner. Use fuel system cleaner to purge water from the fuel system. Lubricate valves, cylinders, injectors, and rings.
