A typical sort of electrical generator seen in tiny engines, such as lawn mower engines, is the magneto. Through the use of magnets and coils, it converts the engine’s rotational energy into electrical energy, which is used to create electricity. The operation of a lawn mower magneto will be discussed in this article, along with other questions relating to small engine repair and maintenance. What Does an Engine’s Magneto Do? A magneto is an electrical generator that can generate high voltage electricity on its own, without the aid of an outside power source. Small engines frequently use it in situations where a battery or other external power source is impractical. The magneto produces electricity by inducing a current in a stationary coil using a revolving magnet. The spark plug in the engine is then powered by this electrical current, and it ignites the fuel and air mixture to produce combustion. What Is the Mechanism of a Lawn Mower Magneto? The magnet and stationary coil are commonly installed on the engine’s flywheel and engine frame, respectively, in a lawn mower magneto. The magnet’s magnetic field passes over the coil as the engine rotates, creating an electrical current. The spark plug receives the current after that, which starts the engine’s combustion process. A capacitor, which stores electrical energy and aids in ensuring precise spark timing, is often also included in the magneto.
When Should a Small Engine Be Rebuilt? Small engines, like those used in lawn mowers, need routine upkeep and sporadic repairs in order to function properly. The engine can eventually require rebuilding, depending on how it has been used and maintained in the past. Excessive oil or smoke production, low compression, or a banging sound are indications that an engine may require rebuilding. Consult a skilled small engine mechanic if you’re unclear whether your engine needs to be rebuilt.
How Can I Obtain a Certification from Briggs and Stratton? A certification program for small engine mechanics is provided by Briggs and Stratton, a top producer of small engines. Online training modules and a certification test are both part of the curriculum. Technicians must finish the online course and pass the certification exam with a minimum score of 80% in order to become certified.
What Materials are Used in Small Engines? Steel, aluminum, and plastic are commonly used in the construction of small engines. While the carburetor and other non-essential components may be made of plastic or aluminum, the engine block, cylinder, and other critical components are typically composed of cast or machined steel. Because the piston and connecting rod are frequently made of lightweight aluminum, the engine’s overall weight is decreased.
In summary, a lawnmower magneto is a crucial part of a tiny engine because it produces the electrical energy required to activate the spark plug and initiate combustion. For small engine mechanics, Briggs & Stratton offers a certification program. Regular maintenance and sporadic repairs are required to keep tiny engines operating efficiently. Steel, aluminum, and plastic are commonly used in the construction of small engines.
