Briggs & Stratton use one of three different types of lubrication systems for single cylinder engines:
- Full Pressure
Splash System for Distributing Oil
With the splash system, a gear-driven dipper or slinger in the crankcase distributes small engine oil to components, preventing clogging of small passages.
On horizontal shaft engines, the dipper is attached to the connecting rod. It picks up oil from the reservoir and spreads it across bearing surfaces as the piston travels through the cylinder.
On vertical shaft engines, a spinning gear with paddles is immersed in oil and slings lubricant throughout the crankcase.
Pressure System for Distributing Oil
Pressure lubrication systems provide a controlled flow of clean oil to bearing for less wear and longer engine life.
A high-efficiency pump in the oil pan supplies lubricant to the crankshaft and connecting rod bearing surfaces. The pressure system incorporates a premium spin-on oil filter. Pressure lubrication is used on select single cylinder engines.
Full Pressure System for Distributing Oil
Full pressure systems are similar to an automobile engine that continuously delivers oil under pressure to critical engine components for maximum lubrication and longer engine life.
A high-efficiency pump in the oil pan supplies lubricant to the crankshaft and connecting rod bearing surfaces. Full pressure lubrication systems use a premium spin-on oil filter. This automotive-style filter provides unsurpassed durability and removes up to 95% of contaminants.
