id0110a7101200
• A silent chain (link grounding type) type has been adopted for the timing chain to reduce tapping noise caused by matching each sprocket.
• Engine oil through cylinder block and cylinder head lubricates the timing chain and each sprocket. The pin of the timing chain is nitride-treated to improve abrasion resistance.

• An oil pressure type chain tensioner has been adopted for the timing chain tensioner. The tension of the timing chain is constantly maintained, using the oil pressure and the spring force in the chain tensioner.
• The oil pressure type chain tensioner consists of the following parts: Piston spring, which depresses the tensioner arm, and the check ball which maintains pressure to the tensioner arm.
