So how exactly do they work, and how do they differ from one another?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A Throwback to the Classic Carburetor<\/h2>\n\n\n\n<p>Carburetors have been around for decades. Their simple mechanism is one of the reasons why many enthusiasts still prefer carburetors in muscle cars and other classics.<\/p>\n\n\n\n<p><strong>Carburetors are entirely mechanical, meaning they don&rsquo;t rely on computers or other electronics to operate.<\/strong> Instead, they work via cables and vacuum systems.<\/p>\n\n\n\n<p>Sitting on <a href=\"https:\/\/www.carparts.com\/blog\/where-is-the-carburetor-located\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"top of the intake manifold\">top of the intake manifold<\/a> and beneath the air filter, the carburetor is responsible for mixing air and fuel before they get to the cylinders.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Principle of Carburetion<\/h3>\n\n\n\n<p>Carburetion is a straightforward process compared to fuel-injection. <strong>Basically, if you step on the gas pedal, the carburetor opens up and delivers the air-fuel mixture to the cylinders.<\/strong><\/p>\n\n\n\n<p>Sounds simple, right? Not quite.<\/p>\n\n\n\n<p>The carburetor is essentially a tube that has a venturi, a restricted air passage in the middle of the tube that helps increase air velocity.<\/p>\n\n\n\n<p>As the velocity increases, a low-pressure pocket forms and helps draw fuel from a nearby jet.<\/p>\n\n\n\n<p>The throttle valve determines the amount of air that goes in the carburetor, so the harder you step on the gas pedal, the wider the throttle valve opens.<\/p>\n\n\n\n<p>Once the jet is done drawing fuel from the tank, the <a href=\"https:\/\/www.carparts.com\/blog\/what-is-a-good-air-fuel-ratio-chart-included\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"air-fuel mixture\">air-fuel mixture<\/a> then travels to the cylinders for combustion.<\/p>\n\n\n\n<p><strong>Carbureted engines can have a single or double barrel.<\/strong><\/p>\n\n\n\n<p>Single-barrel carburetors only have one venturi operating, while double-barrel carburetors have two venturi for additional power.<\/p>\n\n\n\n<p>There are also some vehicles that have four barrels where two of the barrels (primary) are always operating while the other two (secondary) open up at higher speeds.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">It&rsquo;s a Fuel-Injected Auto World<\/h2>\n\n\n\n<p>Mainstream cars began to feature fuel-injected systems during the 1970s, leaving carburetors in the dust not long after.<\/p>\n\n\n\n<p><strong>Compared to carburetors, electronic fuel-injection (EFI) systems are more precise when it comes to producing air-fuel ratios.<\/strong><\/p>\n\n\n\n<p>EFI systems rely on the <a href=\"https:\/\/www.carparts.com\/blog\/car-pcm-meaning-symptoms-of-failure-and-more\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"powertrain control module\">powertrain control module<\/a> (PCM) to pulse the <a href=\"https:\/\/www.carparts.com\/fuel-injector\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel injectors\">fuel injectors<\/a> on and off and operate the fuel pump relay circuit.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<p>Most EFI systems have the following components:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.carparts.com\/fuel-pump\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Electric fuel pump\">Electric fuel pump<\/a><\/li><li><a href=\"https:\/\/www.carparts.com\/fuel-pump-relay\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Fuel pump relay\">Fuel pump relay<\/a><\/li><li><a href=\"https:\/\/www.carparts.com\/fuel-pressure-regulator\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Fuel pressure regulator\">Fuel pressure regulator<\/a><\/li><li><a href=\"https:\/\/www.carparts.com\/diesel-fuel-injector-nozzle\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Fuel injector nozzle\">Fuel injector nozzle<\/a><\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Types of Electronic Fuel-Injection Systems<\/h3>\n\n\n\n<p>There are generally two types of EFI systems: throttle body injection (TBI) and port fuel injection.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Throttle Body Injection<\/h4>\n\n\n\n<p>In a TBI setup, the PCM controls injector pulses in two ways: synchronized and non-synchronized.<\/p>\n\n\n\n<p>Back in the day, TBI had a throttle body with injectors that fired fuel like fuel-injected vehicles. The only difference is that this fired fuel directly into the throttle body and into the intake manifold and then mixed into all the cylinders.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Back in the day, TBI had a throttle body with injectors that fired fuel like fuel-injected vehicles.<\/p><cite><em>&ndash;<\/em><a href=\"https:\/\/www.carparts.com\/blog\/author\/anthonyharlin\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Anthony Harlin, ASE Certified Master Automobile Technician\">Anthony Harlin, ASE Certified Master Automobile Technician<\/a><\/cite><\/blockquote>\n\n\n\n<p>Later there were fuel injected vehicles with a fuel injector for each cylinder.<\/p>\n\n\n\n<p>In synchronized mode, the fuel injector pulses once for each distributor reference pulse. In a non-synchronized setup, the injectors are pulsed depending on the calibration. The pulses are also independent of distributor reference pulses.<\/p>\n\n\n\n<p>Unlike port fuel-injection systems, the regulators on throttle-body-injection systems aren&rsquo;t connected to a vacuum. TBI systems also rely on the nozzle on time to determine the amount of fuel the injectors need to deliver.<\/p>\n\n\n\n<p>In a TBI system, a long pulse width means more fuel while a short pulse means less.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Port Fuel Injection<\/h4>\n\n\n\n<p>In a port fuel-injection system, fuel distribution is equal for all cylinders because each of them has a separate injector.<\/p>\n\n\n\n<p>In this kind of setup, fuel is also injected almost directly into the combustion chamber, leaving no chance for condensation in a cold intake manifold.<\/p>\n\n\n\n<p>Although port fuel-injection systems have separate injectors for each cylinder, they don&rsquo;t fire the same way.<\/p>\n\n\n\n<p>Injectors can be triggered in three ways, namely grouped double-fire, simultaneous double-fire, and sequential.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Measurement Methods for Fuel Delivery in EFI Systems<\/h3>\n\n\n\n<p>Fuel-injection systems have two ways of measuring how much air the engine is breathing in to calculate the appropriate air-fuel mixture: speed density and mass airflow.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Speed Density<\/h4>\n\n\n\n<p>The speed-density method only calculates the amount of fuel the engine needs and doesn&rsquo;t measure air quantity.

Meanwhile, fuel-injection systems are a bit more complex and might require a professional to have them cleaned or replaced.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Versatility<\/h3>\n\n\n\n<p>Carburetors can be modified according to altitudes and driving styles. But unlike fuel-injection systems, they&rsquo;re incompatible with diesel engines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Performance<\/h3>\n\n\n\n<p>Fuel-injection systems can deliver a more precise air-fuel ratio than carburetors because of their electronically controlled fuel induction capabilities.<\/p>\n\n\n\n<p>Meanwhile, carburetors struggle with this concept, especially when the air pressure and fuel temperature are constantly changing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fuel Economy<\/h3>\n\n\n\n<p>The precision of measuring the correct air-fuel ratio means that fuel-injection systems don&rsquo;t waste as much fuel as carbureted engines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cost<\/h3>\n\n\n\n<p>Carburetors are relatively inexpensive to maintain. Fuel-injection systems, on the other hand, can be quite costly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Bottomline<\/h2>\n\n\n\n<p>The carburetor was once the simplest form of fuel delivery in an internal combustion engine. However, it eventually fell out of the limelight with the introduction of fuel-injection systems, which are much more efficient in calculating air-fuel ratios. Emission demands and fuel economy also led to the carburetor&rsquo;s demise.<\/p>\n\n\n\n<p>While carburetors were much easier to maintain, fuel-injection systems were better at doing their job, which makes up for their complexity and costly maintenance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Get a New Carburetor for Your Vehicle<\/h2>\n\n\n\n<p>A bad carburetor may cause engine backfires, stalling, flooding, hesitation on acceleration, and other issues that may affect your vehicle&rsquo;s drivability. As such, it&rsquo;s crucial to replace it once the <a href=\"https:\/\/www.carparts.com\/carburetor\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"carburetor\">carburetor<\/a> shows signs of damage or wear.
