Effect of Excess Lubricating Oil of Diesel Engine on Sudden Unintended Acceleration(SUA)

Even though vehicles are important means of transportation in modern society, they are accompanied by lots of traffic accidents. Sudden unintended acceleration(SUA) is supposed to be one of them. This study investigates the effect of lubricating system of vehicle equipped with turbocharger on SUA from two perspectives which are the quality and quantity of the lubricating oil system. The diluted lubricating oil with diesel oil didn't show deteriorating effect on the consistency of turbocharger at normal quantity. However, excessive quantity of oil showed dramatic effect on engine performance of exhausting white smoke with noise and vibration. This malfunction was thought to be from the flow of lubricating oil through blowby gas ventilation system into combustion chamber. Lest the problem should happen, lubrication management of vehicles is thought to be necessary for both sides of the quality and quantity of the lubricating oil.
