The Science Behind Small Engine Kick Back: Understanding the Basics (Local Tips & Reviews)

Small engine kick back is a common problem for many people who use small engines, and understanding the science behind it can help you avoid it. Kick back happens when the engine suddenly turns in the opposite direction to what you intended, causing the user to lose control of the engine or tool.

So, what causes kick back in small engines? Understanding the basics of the problem requires some knowledge of the internal combustion engine. An internal combustion engine converts fuel into energy by igniting it in a confined space, known as the combustion chamber of the cylinder. The energy released from the combustion is used to power the engine.

To kick back, small engines require two things: ignition timing and compression. Ignition timing refers to the synchronization of the spark plug and fuel injection in a gasoline engine. In some cases, incorrect or inconsistent timing can cause a delayed combustion or partial combustion, leading to a backfire or kickback.

Compression is the amount of pressure built up in the cylinder of a small engine, which is created by the piston compressing the fuel-air mixture in the cylinder during the compression stroke. The higher the compression, the more potential energy the engine has to power itself. However, high compression also creates more resistant pressure on the piston when it’s being turned over.

If the resistance is too high, the engine can’t turn over, creating a sudden release of energy on the machine or tool, which is what results in kickback. Typically, the only way to avoid this is by slowly building up momentum before cranking the engine, or by using a higher quality machine or tool that can withstand the pressure.

In addition to these basic factors, other factors can contribute to small engine kick back, including low-quality fuel, dirty fuel injectors, and an improperly tuned carburetor. The best way to avoid kickback is to ensure your engine is properly maintained, fuelled with high-quality fuel, and used responsibly.

In conclusion, kick back is a common problem that can be mitigated by understanding the science behind it. By remembering the basics of ignition timing and compression, you can better diagnose and prevent the problem from happening. With proper maintenance and usage, your small engine can be reliable and safe to use.
