Parts for your 2017 Mitsubishi Lancer-Fuel injectors

Fuel Injectors in the 2017 Mitsubishi Lancer: What You Need to Know

The 2017 Mitsubishi Lancer, like most modern petrol-powered vehicles, is equipped with fuel injectors. Fuel injectors are a vital component of the car's engine management system, responsible for delivering fuel into the engine's combustion chambers in a precise, controlled manner. This is essential for optimal performance, fuel efficiency, and emissions control. So if you own a 2017 Mitsubishi Lancer or are considering purchasing one, understanding fuel injectors and their maintenance is definitely worth your time.

Fuel injectors replaced older carburettor systems many years ago in most vehicles, including the Lancer. Instead of relying on mechanical parts to mix air and fuel, fuel injectors electronically spray a fine mist of petrol at just the right amount and timing to make sure the engine runs smoothly and efficiently. The 2017 Mitsubishi Lancer uses electronic multi-port fuel injection, which means each cylinder in the engine gets its own injector, right at the intake manifold, for optimal fuel atomisation and combustion.

The purpose of fuel injectors is pretty straightforward but incredibly important. They control how much fuel enters the engine by quickly opening and closing to spray petrol directly into the combustion chamber or intake manifold. This precise delivery ensures that the engine gets the perfect air-fuel mixture for different driving conditions, whether that is idling at a traffic light, cruising on the highway, or accelerating hard. Without properly working fuel injectors, the engine can struggle to run efficiently, causing poor fuel economy, rough idling, misfires, or even increased emissions.

Because fuel injectors operate in an environment where petrol and air mix under pressure, they can get clogged over time due to fuel deposits, dirt, or chemicals in the fuel. That is why maintenance and occasional replacement of fuel injectors can play an important role in keeping the 2017 Mitsubishi Lancer running its best. If fuel injectors become dirty or faulty, the engine might hesitate, lose power, or become harder to start. Replacing faulty fuel injectors is generally recommended if cleaning does not improve the performance, or if there are signs of mechanical failure such as leaks or electrical issues.

Regular servicing of the fuel injectors could involve a few key steps:

• Using quality fuel to reduce the build-up of deposits in the fuel delivery system
• Periodic fuel injector cleaning, either by using fuel additives or professional cleaning machines
• Visual inspections during scheduled maintenance to check for leaks or damaged injectors
• Testing of injector spray patterns and electrical function by a qualified technician

It is also worth noting that fuel injectors on the 2017 Mitsubishi Lancer are designed to be quite durable and generally last the lifetime of the vehicle if the car is well maintained, and quality fuel is used. However, depending on the region or the quality of fuel, some drivers may experience the need to service or replace injectors sooner. For those in Australia, the availability of unleaded petrol with good quality additives means fuel injector troubles are not overly common, but they still happen.

When it comes to replacing fuel injectors, it is generally recommended to use OEM (original equipment manufacturer) parts or high-quality aftermarket injectors that meet or exceed Mitsubishi's specifications. This ensures that fuel delivery remains consistent and the engine management system continues to function optimally. Most service centres recommend replacing injectors as a set rather than one by one, because variations between old and new injectors can cause uneven running. Also, replacing seals and O-rings during injector replacement is a good idea to prevent leaks.

DIY replacement of fuel injectors is possible for those with mechanical skills, but it requires careful work to avoid damaging the fuel rail or connectors, and great care must be taken to ensure safety due to the pressurised fuel system. For most drivers, it is best left to professional technicians who have the right tools and experience to do the job properly.

In terms of fuel economy and emissions, well-maintained fuel injectors help keep the 2017 Mitsubishi Lancer running cleaner and more efficiently. Dirty or failing injectors can cause incomplete combustion, higher fuel consumption, and increased exhaust emissions, which impacts the environment and may cause the car to fail emissions testing.

Keeping up with recommended servicing for the Lancer, which includes inspections of the fuel system, can save headaches down the track. Paying attention to symptoms like rough idling, poor acceleration, or a strong petrol smell can mean it is time to have the fuel injectors checked. Routine maintenance and timely replacement maintain the car's drivability and can extend the life of the engine.
