Balancer

Balancer shaft or balancer is commonly used in four cylinder engines. All in-line four cylinder engines have 2nd order vibration resulting from unavoidable design asymmetry. The balancer, rotating at twice the engine speed, creates its own vertical force that cancels the 2nd order vibration, resulting in smoother engine operation.

Hitachi Automotive Systems Americas, Inc. provides a compact balancer solution that can be adapted to fit inside tight engine environment. Hitachi Automotive Systems Americas, Inc. has long experience with gear and chain drive application for the balancer, making it capable of producing products with best NVH characteristics. Hitachi Automotive Systems Americas, Inc. is constantly improving its technology to reduce frictional loss in its products.

Hitachi Automotive Systems Americas, Inc. also provides special solutions that combine oil pump and balancer into a module. Using the experience learned from producing high quality gerotor pumps combined with balancer, Hitachi Automotive Systems Americas, Inc. has successfully produced the next generation vane type oil pump that are integrated with balancer. This compact solution significantly reduces the assembly complexity at engine assembly plant and provides reliable and efficient product.

Hitachi Automotive Systems Americas, Inc. also supports balance shaft used in 3 cylinder engines. These can also be combined with variable displacement oil pumps.
