YANMAR Engine for CE
YANMAR CE has 4 cycle diesel engine made by YANMAR.
Spark plug
Higher compression and temperature
→ better thermal efficiency (better FOC), less toxic substances
→ Sturdy , tough, heavy-duty engine structure → heavy weight
Self-ignition (No spark plug) → better reliability system.

Eco mode, Auto deceleration
Eco mode
To reduce fuel consumption, Reducing the
engine speed to 90% of high idle engine speed
even when the engine control dial is in the
maximum.
NOTE: The eco mode is not activated when the
engine control dial is set at less than 80%.
Auto deceleration
To reduce fuel consumption, Reducing the
engine speed to low idle after about 4 seconds
since hydraulic actuator(s) have not worked.
NOTE: The auto deceleration function may not
work until the hydraulic oil warms up.
