Mitsubishi auto injector

Types of Mitsubishi Auto Injectors

The Mitsubishi auto injectors come in a variety of sizes and designs, each tailored to meet specific performance needs. Here are some common types:

• Common Rail Direct Fuel Injection

  In this type of fuel injection system, multiple injectors supply fuel into a combustion chamber at high pressure. The fuel is injected into the chamber several times during one combustion stroke. This technique improves fuel atomization, lowering emissions and boosting engine performance. Many modern diesel engines rely on this type of fuel injection system.

• Gasoline Direct Injection (GDI)

  With this system, gasoline is injected directly into the combustion chamber under high pressure. This method allows for precise control of the air-fuel mix, resulting in better fuel efficiency and lower emissions. It's worth noting that the GDI system is compatible with both diesel and gasoline engines.

• Multi-Point Fuel Injection (MPFI)

  The Mitsubishi MPFI system injects fuel into the intake manifold. Each intake manifold has its injector, providing a separate fuel supply for each cylinder. This system improves fuel atomization and distribution, resulting in better engine performance. Compared to older carburretor-based fuel injection systems, MPFI provides a more stable air-fuel mix, which enhances engine start-up and acceleration.

• Throttle Body Injection (TBI)

  In this type of fuel injection system, fuel is injected into the air stream going into the engine's intake manifold. The TBI system resembles carburetors in design but incorporates electronic controls. This system is cost-effective and ensures smoother engine operation.

• Port Fuel Injection (PFI)

  PFI systems inject fuel into the intake ports, mixing it with air before entering the combustion chambers. This type of fuel injection system is quite common in petrol engines. The PFI system allows for better control of the air-fuel mix, resulting in smoother engine performance and lower emissions.

Specifications & Maintenance of Mitsubishi Auto Injectors

• Cleaning

  Every 3000-5000 miles or when having an oil change, users should clean their fuel injectors. They can do this by putting a fuel injector cleaning solution into their gas tank. This will mix with the gas and travel through the fuel system. It will go through the injectors and help wash away any dirt build-up. The cleaning solution acts like a detergent, loosening gunk and allowing it to be flushed out. Using a compression tester, injector cleaner, or fuel pressure gauge can help ensure the injectors are working correctly and make cleaning easier.

• Visual Inspection

  Every 5000-10000 miles, users should visually check their fuel injectors. They should look for signs of leaking fuel, especially around the seals and O-rings where the injectors connect to the engine. Fuel on the outside of the injectors means something is cracked and needs replacing. Fuel also spraying into the engine could cause it to run rough or fail emissions. Users should inspect the wiring harness and connector pins too. Corrosion, damage, or loose electrical connections can prevent the injectors from getting signals from the engine computer.

• Flow Rate Testing

  At around 30000 miles, users can do a flow rate test to ensure their injectors are still spraying the right amount of fuel. They should take the injectors out and put them in a special machine called a fuel injector tester. This will measure how much fuel each one pumps out. All the injectors should be within a certain range of how much they injects. If one is way lower or higher than the others, it needs repair or replacement. The tester also checks for problems like injectors leaking or getting clogged, which could affect performance.

• Electrical Signal Testing

  Users should test the electrical signals going to their injectors every 10000-20000 miles using a multimeter. They should check the voltage and resistance values specified in the owner's manual. If something is wrong, the problem could be with the engine computer, wiring, or the injector itself. Different parts may need diagnosis or repair. A mechanic would be needed to troubleshoot using specialized equipment if the DIY method did not work.

• Professional Servicing

  After around 50000-75000 miles, users should have a professional mechanic clean and test the fuel injectors. The garage will use stronger cleaning machines that can remove tough carbon deposits. They will also do advanced electrical and flow rate tests to find any issues. If the garage finds that any injectors are not working right, they can replace them individually or sometimes as a set, depending on the extent of the damage. Replacing injectors can help restore engine power and fuel efficiency.

How to DIY and Replace Mitsubishi Auto Injector

Mitsubishi auto injector replacement is a simple process that can be done at home. Car owners will need to have some basic tools for the job. These include a ratchet set, torque wrench, 10mm deep socket, 12mm shallow socket, 14mm 12-point shallow socket, 17mm deep socket, and a 19mm 6-point shallow socket. It is also recommended that they have a service manual for reference. The manual will be helpful in understanding the disassembly of parts to reach the fuel injectors.

Once the proper tools have been gathered, follow the steps below:

• 1. Start by relieving the fuel pressure and disconnecting the battery.
• 2. Proceed to remove the air intake duct and vacuum hoses connected to the injectors.
• 3. Remove the 10mm bolts securing the fuel rail and move the fuel rail aside without disconnecting the fuel lines.
• 4. Using a 12mm shallow socket, remove the coil packs located on the left side (driver's side) of the engine. This will give room to access the injectors.
• 5. Next, remove the 14mm 12-point shallow socket bolts that secure the valve covers. Then, remove the 17mm deep socket bolts located at the back of the valve covers. Take note of the bolt sizes and their locations, as they may differ.
• 6. To reach the fuel injectors, one must remove the 19mm 6-point shallow socket bolts found on the ignition coils and disconnect the coils from the wiring harness.
• 7. Finally, remove the 10mm bolts securing the fuel injectors and replace them with new ones. Be sure to lubricate the new injectors with engine oil before installation.

Once the new Mitsubishi auto injectors have been installed, reverse the process and reconnect all the parts disconnected during the process. Reconnect the battery and ensure the engine runs smoothly. It is important to note that different Mitsubishi models have different engine layouts. Some may require more parts to be disassembled to reach the fuel injectors. Always refer to the service manual for guidance.

Q&A

Q1. How can I know if my fuel injectors are bad?

A1. There are several signs that indicate bad fuel injectors. They include rough engine idle, poor fuel economy, decrease in engine performance, and the check engine light being activated. Others are increased emissions, engine misfires, and fuel or oil contaminants. When the engine has oil or fuel contaminants, it is better to let a mechanic take a look to avoid damage to the engine.

Q2. Can I drive with a bad fuel injector?

A2. It is not advisable to drive with a bad fuel injector. This is because a faulty fuel injector either gives the engine too much fuel or too little. If it gives too much fuel, the engine runs rich, which causes damage to the emission system, including the catalytic converter. The car also emits excess hydrocarbons, which is bad for the environment. If the fuel injector is giving too little fuel, the engine runs lean. This causes the spark plugs to foul and puts a lot of strain on the engine as well as on the transmission.

Q3. Can one clean fuel injectors by themselves?

A3. Yes, it is possible to clean fuel injectors without professional help. There are fuel injector cleaning kits that come with fuel injector cleaner. The kits also have pressurized canisters that allow the use of shop air. They also have a fuel rail adapter that is compatible with most vehicles. One can also use a fuel system cleaner that is added to the fuel.

Q4. How often should fuel injectors be cleaned?

A4. Fuel injectors should be cleaned at least every 30,000 miles. However, it is wise to check the owner's manual for the manufacturer's recommended mileage.
