    The 4JB1 diesel engine has a displacement of 2.8 liters (2800 cc). This is the total volume of all the cylinders in the engine.

  • Cylinder Configuration:

    The 4JB1 engine has a inline 4 configuration. This means there are four cylinders arranged in a straight line.

  • Power Output:

    The 4JB1 engine produces between 63-70 kW of power (85-95 hp). This power output is used to drive the vehicle.

  • Torque Output:

    The 4JB1 engine produces between 176-200 Nm of torque. Torque is a measure of twisting force and is used to accelerate the vehicle from a stop.

  • Fuel System:

    The 4JB1 engine uses a direct injection diesel fuel system. Fuel is injected directly into the combustion chamber of each cylinder.

  • Cooling System:

    The 4JB1 engine uses a liquid cooling system. A coolant is circulated through the engine block to absorb heat and then through a radiator to cool down the liquid before returning to the engine.

  • Oil System:

    The 4JB1 engine has an oil lubrication system. Oil is pumped through the engine to lubricate moving parts and reduce friction.

  • Ignition System:

    The 4JB1 engine does not have a traditional ignition system like petrol engines. Instead, diesel fuel is injected into the combustion chamber and ignited by the high pressure and temperature from the compression stroke.

  • Valvetrain:

    The 4JB1 engine has a DOHC valvetrain with 16 valves (4 valves per cylinder). The valves control the flow of air and fuel into the cylinders and exhaust gases out of the cylinders.

Maintenance requirements for 4jb1 parts include the following:

  • Oil Changes:

    Regular oil changes are important to keep the engine running well. Changing the oil every 5,000 km or so (or every 3 months) helps remove dirt and keep the moving parts lubricated.

  • Air Filter Replacement:

    The air filter should be replaced about every 20,000 km. A clean air filter ensures good airflow into the engine for proper fuel combustion and power.

  • Fuel Filter Changes:

    The fuel filter should be changed approximately every 40,000 km. This keeps dirt and debris out of the fuel system, ensuring clean fuel reaches the engine.

  • Coolant Flushes:

    The cooling system needs its coolant flushed and replaced every 80,000 km. This removes old coolant and any buildup, ensuring the engine stays at the right temperature.

  • Spark Plug Inspection:

    Spark plugs (if applicable) should be checked around every 20,000 km. Cleaning or replacing them helps maintain good ignition performance in petrol engines.
