How do points work in a cultivator engine?
In a cultivator engine, points refer to the ignition points or contact points, which are a crucial part of the ignition system. The ignition system in an engine is responsible for generating the high voltage required to create a spark at the spark plugs, which ignites the air-fuel mixture and powers the engine.
The ignition points are typically located inside the distributor, which is a component that distributes the high voltage from the ignition coil to the correct spark plug at the right time. The distributor has a spinning rotor that passes close to the ignition points, which in turn open and close to create a circuit with the ignition coil.
When the engine is running, the ignition points are subjected to mechanical wear due to the repetitive opening and closing action. This wear can cause the ignition points to become pitted, burned, or corroded over time, affecting the ignition system’s performance. If the ignition points are not properly maintained or replaced, it can lead to engine misfire, decreased power, and poor fuel economy.
Working principle of ignition points:
- As the rotor spins inside the distributor, it passes close to the ignition points.
- At the correct moment in the engine’s timing, the ignition points open, breaking the circuit with the ignition coil.
- This interruption of the circuit causes the magnetic field in the ignition coil to collapse rapidly, inducing a high voltage in the secondary coil windings.
- The high voltage is then sent to the spark plugs through the distributor cap and spark plug wires, creating a spark that ignites the air-fuel mixture in the combustion chamber.
- After the spark is generated, the ignition points quickly close again, reestablishing the circuit with the ignition coil.
- This process repeats continuously to provide spark and combustion for each engine cylinder.
It is important to regularly inspect and adjust the ignition points in a cultivator engine to ensure proper functioning of the ignition system. This involves checking the gap between the ignition points using a feeler gauge and adjusting it to the correct specifications. If the ignition points are excessively worn or damaged, they should be replaced with new ones.
Overall, the points in a cultivator engine play a vital role in the ignition system, facilitating the generation of a spark that ignites the fuel and powers the engine. Proper maintenance and replacement of the ignition points are necessary to maintain optimal engine performance.
