Recently, the application of direct-injection gasoline engine (Toyota D-4) is proceeded as one of low fuel consumption technology of vehicle. D-4 pump, a fuel high compression source needs a high performance of friction in gasoline lubrication. We adopted electroless composite plating for the abrasion part of D- 4 pump, and got high anti-abrasion performance plating by developing vibration-plating method.
