J31009 Single-Cylinder 4-Stroke Diesel Engine Teaching Model for STEM Education

J31009 Single-Cylinder Four-Stroke Diesel Internal Combustion Engine Teaching Model Experimental Instrument STEM Toy

Features:

– Finely crafted, reliable quality
– Clear observation of the operation process

Usage:

– Connect the power supply
– Slowly turn the handle in the direction indicated by the arrow

Operating Principle:

a. Intake Stroke:
– Open intake valve, close exhaust valve
– Piston moves from top dead center to bottom dead center
– Fuel-air mixture enters cylinder through intake pipe

b. Compression Stroke:
– Shut off exhaust and intake valves
– Fuel-air mixture compressed in cylinder as piston moves from bottom dead center to top dead center
– Temperature rises rapidly

c. Power Stroke:
– When piston reaches top dead center, spark plug ignites (indicated by light bulb illuminating)
– Fuel-air mixture ignites and expands, pushing piston to bottom dead center
– Crankshaft outputs power

d. Exhaust Stroke:
– Crankshaft passes bottom dead center, piston moves upward
– Exhaust valve opens, exhaust gas expelled from exhaust pipe
– Exhaust valve closes, intake valve opens
– Piston moves down, starting new intake stroke

Notes:

– Powered by electricity, not diesel
– Physics teaching experimental toy
– Observe piston, spark plug, and valve through light changes

Extraordinary Significance:

– For mechanical enthusiasts and collectors
– Decor piece or valuable science education model
– Unforgettable gift for fixed engine model collectors
