    Carburetor Vs Fuel injector Which engine is more reliable, carburettor or fuel injection for bikes? Probably one of the most controversial discussions among motorcycle enthusiasts is the difference between carbureted and fuel injected.

    Fuel Injected motorcycles are fast taking over carbureted ones, which until the beginning of the new millennium ruled the roost. It wasn't until.

Carburetor is the most basic, and until recent times the most prevalent fuelling system used in two-wheelers, especially in India. I mean, the bikes now are faster, but only the tiniest smidgen of that added power can be attributed to fuel injection.

    Carburetion VS Fuel Injection. Fuel Injected motorcycles are fast taking over carbureted ones , which until the beginning of the new millennium ruled the roost.

    As things stand today, almost every premium motorcycle comes equipped with an FI system. So while the good old grease monkeys still swear by the reliability, tune-ability and serviceability of carburetors, newer riders believe that fuel injection is better in every way.

    So how exactly are these two systems work? How exactly are they different and what are their respective virtues and vices? Carburetor is the most basic, and until recent times the most prevalent fuelling system used in two-wheelers, especially in India. To explain the basic working of a carburetor , think of it as a tube that feeds an air-fuel mixture into the cylinder from one end, with an air filter attached to another. Now, somewhere in the middle of this tube the air passage area is restricted to increase the velocity of the air passing through.

    This little area, or part of the carburetor system is known as venturi. By increasing the velocity of the air through the narrow area, a low pressure pocket is created, which in turn facilitates drawing fuel from a jet placed near the venturi through suction.

    The amount of air sucked into the carburetor is decided by a valve at the end of the tube connected to the cylinder. This valve is termed as the throttle valve and is connected to the accelerator grip of your two-wheeler and controls the air-fuel flow through the throttle inputs provided by the rider. When you wring the throttle, the throttle valve opens — allowing a generous flow of air through the carburetor.

    The resultant air-fuel mixture is then supplied to the cylinder where combustion takes place. This is a very basic explanation of how a carburetor works, though modern carburetors including constant velocity or CV carburetors are generally more complex in design.

    These carburetors make use of components like a diaphragm, needle valve and pilot jet to control the air-fuel mixture. The important point to note here, though, is that this entire setup is rather simple and is fully mechanical with no electronics or sensors coming into play. 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. The fuel injection nozzle also goes directly inside the combustion chamber. The pressurised fuel is very well atomised as a homogenous mist in case of FI systems, allowing for very efficient and clean combustion. The fuel supply in case of FI is controlled through an electric brain, or ECU, which constantly makes complex calculations at a very high frequency to deliver the best air-fuel mixture possible.

    Based on a whole variety of parameters such as engine speed, throttle position, engine temperature and load etc the ECU directs the injectors to let in just the right amount of fuel with every intake stroke to facilitate the most efficient combustion. Here, we will discuss the merits and pitfalls of the two systems in brief bullet points. Difference between Mineral vs Synthetic vs Semi-Synthetic engine oils. Which tech do you prefer, and why?
