What is the Difference Between Fuel Injection and Carburettor in Bikes?

Buying insurance for bike is vital. With newer regulations coming in from authorities on a frequent basis, riding a bike without any insurance laced onto it is legally punishable. It not only brings you financial loss but also causes unnecessary hassles if the bike gets involved in any collision or accident.

However, while buying insurance for bike, you might come across terms such as fuel injection and carburettor on the policy page. These terms seem technical but you still need to know why they are relevant. Read on to understand why they are different as well before you make your mind and buy insurance for bike from HDFC ERGO.

Last April in 2020, Indian vehicles moved to emission norms of the Bharat Stage VI or the BSVI category, from the earlier Bharat Stage IV or BSIV grade. This move to newer emission standards was tight and strict given that mechanical alterations to bikes and two-wheelers have turned to be much more extensive. The BS6 norms for emission have become stringent to a point that the importance of fuelling has become manifold. The latest bikes being manufactured all come with a fuel injection setup instead of the older carburettor. This naturally has enhanced bike prices largely.

Difference between the Setups- Carburettor and Fuel Injection

The bike remains mobile based on the simple functionality of provision of fuel and air to its combustion engine. Now an inbuilt device controls the proportion in which the fuel and air mix up as it enters the bike engine. This device is the carburettor. Of late, this device has seen substitution with an entire fuel injection setup that does the exact same job. However, the latter does this job with the help of sensors and advanced electronic parts. The earlier carburettors performed based on mechanical parts.

The parts worked in separate scales to deliver the air and fuel mixture in a fixed ratio to the engine. This kept the bike mobile. Whenever the bike throttle saw use, the carburettor air flow increased. This caused more fuel delivery and air suction. This, in turn, increased the bike speed.

Naturally the carburettor was the basic mode of a bike’s operations and came with a large number of advantages

·Carburettors are affordable and easy to repair or even replace.

·These devices had lighter mechanical parts and lasted long.

·Bike riders had the option to control the carburettor as per their need of power and mileage.

·Carburettors were not built into the engine and could be serviced, repaired or changed easily.

●However, carburettors turned out to be less on fuel efficiency over the long run. These caused lags that caused slow responses from the bike's throttle body. Naturally, this leads to more replacements of the carburettor. The internal diaphragm of the carburettor too saw much damage and frequent replacements.
●These clumsy defects lead to manufacturers shifting to the fuel injection system that employs more advanced working principles. The newer system might see damages but these are covered under the comprehensive policy cover when you opt for relevant add-ons as you buy HDFC ERGO’s insurance for bike.
●This system used a fuel pump for fuel flow control to the bike’s combustion chamber. This pump is part of the fuel; tank in the bike. The electronic control unit enables the fuel supply level and mixes the right proportion of air. All the ratios see calculation as per sensor-based monitoring in the fuel injection system.

Factors that trigger the fuel flow into the tank are-

·Position of throttle

·Engine speed

·The engine temperature

·Engine load

The advantage of this fuel injection setup lies in its enhanced accuracy of the air and fuel mixture. It leads to an efficient and cleaner combustion process. This naturally leads to better mileage on the bike and lower maintenance needs that arise from wear and tear. You also get to control the system using ECU mapping. Of course, all this technology makes the system more expensive than the traditional carburettor and it employs complex working principles to operate the same.

The Final Choice

Ultimately, the automobile sector for bikes is gradually shifting towards the fuel injection system despite the expenses and complexities involved. This is more so because of lesser carbon emissions that result from the latter. The throttle response, lower maintenance needs and better fuel efficiency also keep bike owners happy.
