Does a Diesel Engine Runaway Need an Overhaul?

[DiRuby]

Diesel engine runaway does require an overhaul. There are two main causes for runaway: one is excessive diesel fuel supply, and the other is engine oil entering the cylinder combustion chamber and burning. If not handled properly during driving, runaway can potentially lead to traffic accidents. Below are the causes and solutions for runaway: 1. Excessive diesel fuel supply: This causes thick black smoke from the exhaust pipe. You can inspect the components of the fuel supply system, analyze the issue, and then proceed with repairs, such as the fuel pump, injector, governor, and other parts. 2. Engine oil entering the cylinder combustion chamber and burning: This results in blue smoke from the exhaust pipe. You can check the components of the lubrication system to determine if too much oil has been added or if the oil does not meet the required specifications.
