This is where the oil for lubricating the engine is stored and can be easily accessed for maintenance purposes. Additionally, 4-stroke engines typically have an overhead valve design, with the valve cover situated on the top of the engine. This design is characteristic of 4-stroke engines and differs from the simpler side valve design of 2-stroke engines.
Furthermore, 4-stroke engines have a fuel tank for holding gasoline, which is usually located above the engine. This tank provides fuel for the engine and is a prominent feature of 4-stroke models. Additionally, 4-stroke engines have a more complex internal structure with separate compartments for air intake, compression, combustion, and exhaust processes. Understanding these distinguishing features can help you confidently identify a Briggs and Stratton 4-stroke engine and differentiate it from 2-stroke models.
Operating And Maintaining 2-Stroke Engines
When operating and maintaining 2-stroke engines, it’s important to be mindful of a few key considerations. First, always use the correct fuel-to-oil ratio as specified by the manufacturer.
