DenmarkScooter Engine

Product Description

Function

● Variable-Flow Intake Technology: Optimizes the intake airflow path for more complete combustion, greater power output, and lower fuel consumption.
● Piston cooling technology: enhances resistance to thermal deformation, improves piston cooling and lubrication, and results in lower thermal load compared with engines of the same displacement and type, leading to lower cylinder-head and oil temperatures.
● Unique centrifugal weight-type pressure-reducing mechanism: simple structure, more stable pressure reduction, easy starting, and enhanced starting performance as well as longer service life for the starter motor and battery.
● Oil-level sight glass design: facilitates real-time monitoring of the crankcase oil level.
