Well you seem to not like to answer questions which is not helpful for anyone to assist in a solution.
Since you made a somewhat incorrect statement about how diesels work I will provide a short explanation for your clarity.
The fuel is pumped to the injectors. The pressure from the injector pump is what cracks open the injectors (on older style engines). The timing of the injection is just before top dead center of each cylinder (each cylinder has its separate injector). On newer engines the fuel is pumped into a common high pressure rail that is feeding all the injectors. Then the timing of the fuel injection is controlled by the ECM that electrically opens the injectors one at a time.
On the cylinder side most tractors are four stroke engines. The first down intake stroke takes in the air. The second up stroke compresses the air which heats it. The fuel is injected into the cylinder (or a pre ignition chamber that is still really part of the head). The fuel ignites (if the proper amount is delivered at the proper time). The third stroke is down and is caused by the increasing volume of burning fuel and air. The fourth stroke is the exhaust stroke that exhausts the burnt (or burning) fuel air mixture into the exhaust system.
Here are possible causes of clacking from a cursory search of the internet that may show why questios on fuel were asked (but never answered yet).

A clacking noise in a diesel engine often indicates issues such as low-quality fuel, incorrect fuel type, or mechanical problems like worn bearings or a loose timing chain. It's important to diagnose the cause promptly to prevent further engine damage.

Symptoms to Watch For
- Audible Clacking: A distinct sound that may vary with engine speed.
- Reduced Performance: Sluggish acceleration or decreased power.
- Increased Fuel Consumption: The engine may burn more fuel than usual.
- Check Engine Light: Sensors may detect irregular combustion.
- Check Fuel Quality: Ensure you are using high-quality diesel with the correct cetane rating.
- Inspect Engine Components: Look for loose or damaged parts, especially around the injectors and timing chain.
- Monitor Oil Levels: Low oil can lead to inadequate lubrication, causing clacking noises.
- Consult a Mechanic: If the noise persists, professional diagnosis is recommended to prevent further damage.
