தம்பி,,,you have to study.. automobile engineering a lot....can't talk a technology by seeing videos... 1)carburettor is a device which mixes air and fuel in a ratio...deponds upon ratio,it's called as rich mixture,lean mixture and optimum..evolution of carburettor is advanced by electronic,electrical, mechanical and lot...and also efficiency is different from mileage....
2)hey you brilliant man...let me teach you....in simple carburettor,it is not sufficient to supply air fuel ratio for different conditions like idling,acceleration,normal running and load...so the mechanical carburettor is replaced by solex carburettor and then advanced by electrical and electronic carburettor....
4) carburettor does not 🚭 does not related with wear and tear.....😢😢😢😂😂😂
3)bhp and torque is different...knocking is heavy sound inside cylinder due to abnormal combustion.may be advanced or delay...in combustion spark..gdi does not have that problem...😢study a lot about gdi in terms of engine ,and lot 😊ecm காக injection வரல....injector ah control பன்றதுகாக ECM programming வந்துச்சு....சக்தி ...யாரையோ வச்ருக்கான் 😢comedy...
i dont understand where you even studied this incomplete knowledge.....even in bike people used to clean carburetor and it used to have gasket needle shaft and many more components and your saying its not related to wear and tear.......before negative critic give some valuable info.....dont simply post a rubbish comment
@@_VASANTHNARAYANANE ok explain me...what is rubbish in my concept..am open to discuss in public..bike fuel injection is not new and it have been started from Apache ........what's wrong with it....let us take it as a good informative healthy challenge.....am not a fool like u to nod my head always....

Carburetor Vs Fuel Injection
Since the invention of the internal combustion engine, engineers have been trying to find more effective ways to deliver fuel and air into the combustion engine. Considering the rising pollution in India, the country has moved from BS4 to BS6 emission standards, demanding more extensive mechanical changes in bikes and two-wheelers. Since they require accurate fuelling, many auto manufacturers have switched to fuel injection systems from carburettors.
A carburettor engine controls the ratio of air and fuel entering the engine. A fuel injection system is also responsible for doing the same. So, what is the difference between them? Simply put, a carburettor feeds the air-fuel mixture to the combustion chamber through mechanical components. The fuel injection system also does the same but with electronic sensors and electronic parts. In the following sections, we will briefly overview carburettor vs. fuel injection.
What is a Carburettor?
A carburettor is a device supplying a mixture of air and fuel to the bike’s spark-ignition engine. Its major components include a choke, idling, storage chamber, venturi-shaped restriction, accelerator pump, and a main jet. When the engine ignites, the choke controls the air intake and sends a fuel-rich charge to the cylinders. As the machine becomes warm, the choke opens gradually, and the main fuel jet gets activated and injects fuel into the inlet to drive the vehicle.

How Does Carburettor Work?
The primary purpose of a carburettor engine is to mix air and fuel in a particular ratio and send it to the bike's combustion chamber. It cuts off the airflow to the combustion chamber, mixes fuel, and feeds it to the engine. The carburettor airflow increases when you squeeze the bike's throttle, causing air suction and delivering the fuel to improve acceleration.
Technically, the carburettor is like a tube regulating fuel delivery to the engine to increase air velocity. The part restricting the fuel is called the venturi. As the air velocity increases, a low-pressure space builds up, facilitating the drawing of fuel from a jet near the venturi. It creates a mixture of air and fuel that burns in the combustion chamber to create a vacuum venturi effect.
What is a Fuel Injection?
Considering the rising pollution levels in India, new legislation instructed auto manufacturers to reduce their pollutant emissions and improve fuel efficiency. After several years of research, engineers developed the fuel injection system that helped accomplish these objectives. It uses new computer technologies to control air and fuel consumption without compromising power. Gradually, fuel injection systems replace all carbureted fuel systems in almost all gasoline engines.
How Does Fuel Injection Work?
The fuel injection system has a complex set of sensors and electronic parts that depend on a fuel pump to control the fuel flow in the combustion chamber. Located inside the bike’s fuel tank, this fuel pump supplies fuel to the combustion chamber through an ECU (Electronic Control Unit). It is like an electric brain that constantly regulates and calculates the air-fuel mixture to deliver a perfect concoction to the engine.
The ECU calculates the ideal mixture requirement based on several parameters like the engine speed, throttle position, load, engine temperature, etc. The fuel injection system has a nozzle that goes right into the cylinder chamber. The ECU instructs the injection system to send a controlled amount of fuel to the engine, enabling the most effective combustion mode.
Key Differences Between Carburettor and Fuel Injection
Let’s look at the key difference between carburettor and fuel injection:
Parameter Fuel Injection Carburettor
Inception
A newer innovation, first used in petrol engines in 1925

Very nicely explained good bro
Knocking have been eliminated in advanced gdi engines ....
Different between knocking and misfiring in engine
Knocking and misfiring are two distinct issues that can occur in an engine, each with different causes and symptoms. Here's a breakdown of their differences:
Knocking (Detonation)
Definition:
Knocking, also known as detonation or pinging, is a phenomenon where fuel in the cylinder ignites prematurely or irregularly due to high pressure and temperature conditions, causing a knocking or pinging sound.
Causes:
Low-octane fuel that cannot withstand high compression.
High engine temperatures.
Incorrect ignition timing.
Carbon deposits in the combustion chamber.
High boost levels in turbocharged engines without proper tuning.
Symptoms:
A distinct knocking or pinging sound, especially during acceleration or under load.
Potential loss of power.
Increased exhaust emissions.
Possible engine damage over time if left unchecked, such as piston damage or bearing wear.
Effects:
Reduced engine efficiency and performance.
Increased risk of engine damage if persistent.
Solutions:
Use higher-octane fuel.
Adjust ignition timing.
Ensure proper cooling.
Clean carbon deposits.
Proper tuning for turbocharged engines.
Misfiring
Definition:
Misfiring occurs when one or more cylinders in an engine fail to ignite the air-fuel mixture at the proper time or fail to ignite at all, causing a stumble or loss of power.
Causes:
Faulty spark plugs or ignition coils.
Problems with the fuel delivery system (clogged injectors, bad fuel pump, etc.).
Air intake issues (vacuum leaks, clogged air filter).
Faulty sensors (oxygen sensor, mass air flow sensor, etc.).
Engine compression problems.
Wiring or electrical issues.
Symptoms:
Rough or uneven idling.
Loss of power and acceleration.
Increased fuel consumption.
Backfiring or popping sounds from the exhaust.
Check engine light illumination.
Increased emissions.
Effects:
Reduced engine performance and fuel efficiency.
Potential damage to the catalytic converter from unburned fuel.
Increased wear and tear on engine components.
Solutions:
Replace faulty spark plugs or ignition components.
Clean or replace fuel injectors.
Check and fix vacuum leaks or air intake issues.
Replace or repair faulty sensors.
Address engine compression issues if present.
Inspect and repair electrical wiring as needed.
Understanding these differences is crucial for diagnosing and fixing engine problems effectively.
Gdi engine positives and negatives...do gdi engines prone to knocking???
ChatGPT
Gasoline Direct Injection (GDI) engines are a type of internal combustion engine where fuel is injected directly into the combustion chamber rather than into the intake manifold. This technology offers several advantages and some disadvantages compared to traditional port fuel injection (PFI) engines. Here's a detailed look at the positives and negatives of GDI engines and their susceptibility to knocking:
Positives of GDI Engines
Improved Fuel Efficiency:
Direct injection allows for more precise control over the fuel-air mixture, leading to better combustion efficiency and improved fuel economy.
Increased Power and Torque:
GDI engines can deliver higher power output and torque because of the improved combustion process. The fuel is atomized more finely and mixed more thoroughly with the air.
Lower Emissions:
With more efficient combustion, GDI engines can produce lower levels of carbon dioxide (CO2) and other greenhouse gases. Advanced GDI systems can also help reduce particulate matter (PM) and nitrogen oxides (NOx) with proper after-treatment systems.
Better Throttle Response:
The precise control of fuel injection allows for quicker throttle response and better overall performance.
Lean-Burn Capability:
GDI engines can operate in a lean-burn mode under certain conditions, using less fuel and improving efficiency further.
Negatives of GDI Engines
Carbon Buildup:
GDI engines are prone to carbon buildup on the intake valves and other parts of the intake system because the fuel does not wash over the intake valves as it does in PFI engines. This can lead to reduced performance and fuel economy over time and requires periodic cleaning.
Complexity and Cost:
The technology and components used in GDI engines are more complex and expensive to manufacture and repair compared to PFI systems.
Potential for Increased Emissions of Particulates:
GDI engines can emit higher levels of particulate matter (PM) due to the fine fuel atomization, which might necessitate additional emission control technologies like particulate filters.
Noise:
Some GDI engines can be noisier than their PFI counterparts due to the high pressure used for fuel injection.
Susceptibility to Knocking
GDI engines can indeed be more prone to knocking (detonation) compared to PFI engines, primarily due to the following reasons:
High Compression Ratios:
GDI engines often run at higher compression ratios to improve efficiency and power output, which can increase the likelihood of knocking if the fuel is not of sufficient octane or if the combustion process is not managed properly.
Advanced Timing:
The precise control over injection and ignition timing in GDI engines can sometimes lead to conditions that favor knocking, especially if there are calibration issues or if low-octane fuel is used.

@@birlasparvai Done bro 👍 pls check your mail
Power & Torque can be tuned as per design intentions. It need not be due to GDI technology.
But overall the video is very well made 🙏🏽👍🏽👏🏽👏🏽👌🏽👌🏽
GDI engine carbon deposits leads to sometimes to engine failures; Kia/ Hyundai cars have been reported have issues with GDI engines in USA? These engines require regular maintenance.
Every car must prove its own driveability and service related problems at least by one year. Definitely Birla is underlineing the service cost may come more in GDI engine rather mpfi.. Suitable for middle class like us and long run
Petrol will not get into the crank case unless and until the piston rings are getting wore or damaged..
Most expected. Thank you 🙏
