  • How do carburetors work? This video explains carburetors and the components involved. They are used to mix the fuel into the air entering the engine, and are placed just before the throttle body.
    The technology is old, however is still used in small engine applications such as lawnmowers, weedwackers, chainsaws, etc.

      Well you do have to understand the physics to truly understand what makes it work, otherwise you don't really know why it works, just that it does by being a certain way.

  • @EngineeringExplained
    @EngineeringExplained  Před 11 lety +20

    The choke is used to restrict air-flow at the start in order to inject more fuel for starting the engine. After that, the choke is left open and the throttle valve controls the airflow.

  • @EngineeringExplained
    @EngineeringExplained  Před 12 lety +2

    @Veggies94 Depends on the setup, can be either or, but one carb is more common leading to the intake manifold. Higher performance engines (older, obviously) may use one per cylinder.

    In a carbureted car it may not be much different either way, maybe less in neutral since it will be revving lower, then again in gear it doesn't need any fuel to continue moving. Regardless, it's a very minimal gain. If you're looking to save fuel there are much better methods. Drive slower, accelerate slower, etc...

    I'm sure it could be fine tuned to optimal fuel efficiency, carbs were used in NASCAR I believe up until just recently, I'm sure they had them dialed in right. That said, it's very difficult to compete with direct injection, as this allows for the fuel to be injected at the exact times when it will yield the most power or the best fuel economy, something carbs cannot regulate.

  • @phillipranglin7928
    @phillipranglin7928 Před 7 lety

    Amazing video! I'm trying to convert a carburetted gas generator to run on propane, and I didn't want to proceed until I understood how the mechanism worked (since I'm otherwise exclusively a diesel/cooking oil person). This fills in all the scientific gaps, so thank you!

  • @EngineeringExplained

  • @EngineeringExplained

    Yes, it's possible. you would have the carb placed after the device creating boost (turbo).

    Yes, more air means more fuel can burn. It's balanced. However, with a diesel vehicle the gas pedal actually does increase the amount of fuel injected (the ratio of air to fuel goes down).

    Unrivaled knowledge coupled with a natural talent for teaching... add to this the seldom-seen ability to include only what we really need to know, and what we have is an absolutely indispensable learning resource. The fact that, through CZcams, we get all that for free necessitates the burning question: why are we paying $$$$s each year for inferior quality tuition from our colleges? Huge respect to EE!

    The explain of pressure difference causing fuel to move is spot on. Most people think that the fuel is being sucked out of the bowl when in fact it is the difference of pressure that causes the fuel to be drawn out into the annular booster sitting in the middle of the venturi to be atomized.
