Question

What is the reason that some bikes, such as the Pulsar, can be started with a quick twist, and why does this method start the bike instantly and without any struggle?

Answer 1

Bikes like the Bajaj Pulsar have a feature called an electric starter, which allows for quick and effortless starting with a simple twist of the key. This method is designed to provide instant and smooth ignition without the need for any physical effort. Here's how it works:

1. Electric Starter Motor: The electric starter is a small electric motor located near the engine. When you twist the key, it activates the starter motor.

2. Battery Power: The electric starter motor is powered by the bike's battery. The battery provides the necessary electrical energy to turn the starter motor.

3. Starter Gear Engagement: As the starter motor turns, it engages with the starter gear, also known as the Bendix gear or starter clutch. The starter gear meshes with the engine's flywheel or starter ring gear.

4. Crankshaft Rotation: As the starter motor spins the starter gear, it transfers rotational force to the engine's flywheel or starter ring gear. This causes the crankshaft to rotate, initiating the internal combustion process.

5. Ignition and Fuel System Activation: As the crankshaft rotates, it triggers the ignition system, which generates a spark to ignite the air-fuel mixture in the engine's cylinders. Simultaneously, the fuel system delivers the required fuel to facilitate combustion.

6. Engine Start: With the spark and fuel in place, the engine starts running, and the starter motor disengages from the engine's flywheel or starter ring gear.

The electric starter provides several advantages over kick-starting methods used in older bikes. It eliminates the need for physical effort, making starting the bike easier, especially in situations where the engine might be cold or when repeated attempts are required. The electric starter system relies on battery power, which provides consistent and reliable energy, ensuring a smooth and instant start every time.

It's important to note that electric starters require a functioning battery and electrical system to work correctly. Regular battery maintenance and charging are necessary to ensure optimal performance and reliable starting of the bike.
