The recoil starter in a lawn mower is a manual starting mechanism that helps you start the engine. Here’s how it works and what it does:
Function of a Recoil Starter:
- Starts the Engine Manually:
- When you pull the recoil starter rope, it spins a spool inside the starter assembly.
- This rotation engages the flywheel and crankshaft of the engine.
- The movement creates compression and ignition, which starts the combustion process.
- Engages and Disengages Automatically:
- The recoil mechanism has spring-loaded pawls (or dogs) that engage the engine’s flywheel when you pull the rope.
- Once the engine starts, the pawls retract so the starter disengages and doesn’t interfere with engine rotation.
- Uses a Spring to Rewind:
- After the rope is pulled, a spring mechanism rewinds the rope back into the housing, ready for the next use.
In Simple Terms:
It’s like a hand-crank system—you pull the cord to spin the engine fast enough to start it, and the recoil mechanism makes the cord snap back automatically.
