Purpose, Function
• The balancer unit eliminates the secondary inertia force occurring in the in-line 4-cylinder engine which reduces engine vibration. As a result, booming noise (low frequency noise which causes the feeling of ear compression) is suppressed and a high-level quietness has been achieved.
Construction
• The balancer unit is installed on the lower part of the cylinder block.

|
• The balancer unit consists of two balancer shafts with weights (No.1 and No.2) and the balancer unit case.
• Agitation resistance has been reduced by covering the balancer shafts and gears with the balancer unit case.

Operation
• The balancer shaft rotates by receiving the crankshaft rotation force via the balancer shaft sprocket.
• The balancer shaft rotation speed is twice the rotation speed of the crankshaft. As a result, the balancer shaft can generate inertia force (eliminates secondary inertia force) in the opposite direction in response to the occurrence of secondary inertia force.
