Question

Which automotive brand do you think provides a better value, Toyota or Honda?

Answer 1

In a Honda Activa or any internal combustion engine, the spark plug plays a crucial role in igniting the air-fuel mixture inside the combustion chamber. Here's how a spark plug works:

1. Ignition System: The Honda Activa is equipped with an ignition system that generates a high voltage electrical current. This system includes a magneto or ignition coil, which produces an electrical charge.

2. Spark Plug Design: The spark plug is a threaded metal component that is screwed into the cylinder head of the engine. It consists of a center electrode, ground electrode, and an insulator in between. The center electrode extends into the combustion chamber.

3. Ignition Process: When the engine's piston is in the compression stroke, the air-fuel mixture is compressed inside the combustion chamber. At the right moment, the ignition system sends a high-voltage electrical current to the spark plug.

4. Electrical Spark: The high-voltage current creates an electrical arc or spark between the center electrode and the ground electrode of the spark plug. This spark ignites the compressed air-fuel mixture, causing combustion.

5. Flame Propagation: Once the spark ignites the air-fuel mixture, a flame front is generated. The flame front rapidly spreads across the combustion chamber, igniting the rest of the mixture.

6. Power Stroke: The ignited air-fuel mixture creates a rapid expansion of gases, pushing the piston down in the power stroke. This mechanical energy is then transferred to the crankshaft, resulting in the rotation of the engine's output shaft and generating power.

7. Repeat Cycle: The combustion process repeats in each cylinder of the engine, synchronized with the engine's four-stroke cycle (intake, compression, power, and exhaust).

Over time, spark plugs can become fouled or worn due to normal use. It's important to regularly inspect and maintain the spark plugs in your Honda Activa according to the manufacturer's recommendations. This includes cleaning or replacing spark plugs when necessary to ensure optimal engine performance and fuel efficiency.
