Why Sensor in Carburettor bikes

Summary

The video discusses the importance of sensors in modern motorcycles, focusing on the throttle position sensor (TPS). It explains how older bikes lacked advanced features, but newer models like Bullet and Splendor include sensors that enhance performance. The TPS collects data on throttle input and sends it to the ignition coil, which helps regulate the engine's efficiency, reduce vibrations, and improve overall bike performance. The video highlights the working mechanism of sensors, their role in maintaining engine balance, and how they contribute to smoother and faster rides.

Takeaways

• 🔧 The video explains the function of a sensor used in modern bikes, known as the Throttle Position Sensor (TPS), which measures how much throttle is applied.
• 🚲 In older bikes, there was no such sensor, yet they still ran fine. However, new bikes and scooters come with this feature to improve performance.
• ⚙️ The TPS sends information to the bike’s ECU (Engine Control Unit) about the throttle position, which adjusts engine parameters for better efficiency and performance.
• 🔥 This sensor ensures accurate ignition timing, sending signals to the ignition coil, which generates a spark for combustion in the engine’s combustion chamber.
• 💡 The video emphasizes that even though older bikes like the Splendor didn’t have such sensors, the sensor helps in reducing engine vibrations and enhances power output in newer models.
• 🔄 The TPS works in sync with other engine functions like the piston and combustion chamber, and helps maintain a balance between power output and engine efficiency.
• 🛠️ The video explains the process of how the sensor adjusts the spark advance depending on throttle input, providing better engine performance at different RPMs.
• 💨 Removing the sensor might result in the bike running, but it would not achieve the same speed or pickup efficiency as with the sensor installed.
• 🔍 The sensor helps in reducing vibration and power loss, especially at high speeds, by optimizing the engine's combustion process.
• 👍 The video concludes by advising viewers to appreciate the TPS sensor's role in improving the smoothness and performance of modern bikes, and encourages sharing and subscribing.

Q & A

What is the main topic of the video script?

The main topic of the video script is the role and function of the Throttle Position Sensor (TPS) in motorcycles, specifically how it helps in managing the ignition and improving vehicle performance.

What is the function of the Throttle Position Sensor (TPS) mentioned in the video?

The Throttle Position Sensor (TPS) monitors the position of the throttle in a motorcycle and sends information to the ignition system, ensuring the right amount of fuel-air mixture is delivered to the engine based on the rider's input.

Why was there no TPS in older motorcycles, and how did they operate?

Older motorcycles did not have TPS, yet they still operated without it because their systems were more mechanical. Riders could still drive without it, but these bikes lacked the precision in throttle response and fuel management that modern bikes with TPS have.

What does TPS communicate with to help the bike function properly?

The TPS communicates with the ECU (Electronic Control Unit) to provide information about the throttle position. The ECU then adjusts the ignition timing and fuel injection to optimize the engine's performance.

What are the benefits of using a TPS in modern motorcycles?

The benefits of using TPS include smoother throttle response, reduced vibrations, improved fuel efficiency, better power output, and overall improved performance compared to bikes without this sensor.

How does TPS help with reducing power loss and vibrations in motorcycles?

TPS helps by precisely adjusting the ignition timing based on the throttle input, which reduces power loss and vibrations, leading to a smoother ride and better power transfer.

What is TDC and BDC as explained in the video?

TDC stands for Top Dead Center, which is the highest point a piston can reach in the engine cylinder. BDC stands for Bottom Dead Center, which is the lowest point. These positions are critical for engine operation and timing, with TPS helping the system know when the piston reaches TDC or BDC.

What role does the TPS play in ignition timing?

TPS helps in adjusting the spark timing by sending signals about the throttle position. If the throttle is opened more, it advances the ignition timing to provide the necessary spark at the right time, improving engine efficiency and power output.

How does TPS contribute to better acceleration in motorcycles?

TPS ensures that the right amount of fuel and air mixture enters the engine when the throttle is opened, leading to a more precise and efficient combustion process, which results in better acceleration and smoother power delivery.

What is the main advantage of using a TPS in high-performance motorcycles?

The main advantage is that TPS allows for more accurate control of fuel injection and ignition timing, which is essential for maintaining optimal performance, especially at higher speeds and under varying load conditions.
