The fuel system is crucial for the effective operation of the tractor engine. Without a properly functioning fuel system, your engine may have trouble starting, run erratically, or stop running altogether. Regular maintenance and monitoring of the condition of the fuel system are essential to ensure the reliability and longevity of the tractor, as well as optimal fuel consumption and minimization of exhaust emissions.

Main parts of the fuel system:

• Fuel tank: Stores the fuel that is necessary for the engine to run.
• Fuel pump: Transfers fuel from the tank to the injection system or carburetor (on older models).
• Fuel filter: Removes impurities and deposits from fuel, protecting injectors and other system components from damage.
• Fuel lines: Transport fuel from the tank to the fuel pump and on to the injectors or carburetor.

Principle of operation of the fuel system:

• Fuel delivery: Fuel is drawn from the tank by the fuel pump.
• Filtration: The fuel passes through the fuel filter, where contaminants are removed.
• Transport: Clean fuel is transported through fuel lines to the injectors.
• Fuel injection: Injectors introduce fuel into the combustion chamber in the right amounts and at the right time.
• Combustion: Fuel is mixed with air and burned in the combustion chamber, producing energy that powers the engine.

Types of fuel systems:

• Carburetor system (older models): Fuel and air are mixed in the carburetor before entering the combustion chamber.
• Injection system (modern models): Fuel is injected directly into the combustion chamber through injectors, which allows for more precise control of the air-fuel mixture.

Fuel System Maintenance:

• Checking the fuel level regularly: Make sure the fuel tank is properly filled.
• Replacing fuel filters: Change fuel filters regularly to keep fuel clean and protect injectors and other system components.
• Fuel Line Condition Inspection: Check the lines for leaks, cracks, and other damage.
• Injector Cleaning: Clean or replace your injectors regularly to ensure proper fuel injection.
• Checking the fuel pump: Make sure the fuel pump is operating properly and delivering fuel at the proper pressure.
