[9] BUILT-IN DYNAMIC BALANCER (BALANCER MODEL ONLY)

The 07 series DI engine employs gear train located at
flywheel side. The following benefits are in the rear gear
train configuration.
1. Flexibility of auxiliary parts arrangement.
2. Reduction of gear chattering noise from crankshaft of
torsional and bending vibration.

Piston's skirt is
disulfide , which reduces the piston slap noise and
thus the entire operating noise.
Molybdenum disulfide (MoS
The molybdenum disulfide (1) serves as a solid
lubricant, like a Graphite or Teflon. This material helps
resist metal wears even with little lube oil.

Engines are sure to vibrate by piston's reciprocation.
Theoretically, three-cylinder engines are much less
prone to cause vibration than four-cylinder ones (second
inertia, etc.). However, any engine has many moving
parts in addition to its pistons and cannot be completely
free from vibration.
The four cylinder engine is fitted with balance weight
on crankcase to absorb the second inertia mentioned
above and reduce vibration.
