What is the reason why the diesel engine won't start after adding fuel when it runs out of oil?

[HarperAnn]

Diesel engine won't start after adding fuel when it runs out of oil, the reasons may be excessive carbon deposits on the idle motor and intake valves. Here are the specific details: 1. Main reasons: It may be due to excessive carbon deposits on the idle motor, intake tract, intake valves, and combustion chamber, or failure of the carbon canister or carbon canister solenoid valve. 2. Excessive carbon deposits: Due to excessive carbon deposits and dirt in the intake tract, the cross-sectional area of the air passage changes, causing the mixture to be too rich or too lean, resulting in abnormal combustion or engine shaking after starting, or even failure to start. Or it may be due to problems with the fuel injector, such as leakage or excessive carbon deposits, causing the mixture to be too lean during startup, making it difficult to start.
