Tips for Proper Electronic Fuel Injection System Maintenance﻿ Electronic Fuel Injection (EFI) systems have been standard in vehicles since the 1980s, but many car owners may not understand the role this system plays in their car's performance.  Despite their widespread use, a significant number of car enthusiasts and everyday drivers alike may not fully grasp the crucial function these systems perform in enhancing a vehicle's overall performance and efficiency. The EFI system, which replaces older carburetion methods, precisely regulates the mixture of fuel and air delivered to the engine, thereby optimising combustion, resulting in improved fuel economy, reduced emissions, and enhanced engine responsiveness. Understanding the intricacies of how EFI systems work can provide valuable insights into maintaining your vehicle and appreciating the technological advancements that keep your engine running smoothly. EFI is a complex system that requires proper maintenance to keep it running efficiently. This article will explain what an EFI system does, how it works, why servicing it is important, common EFI problems, and basic service steps. By following these tips, you can ensure your car runs smoothly for years to come.﻿ What Does an EFI System Do?﻿ An EFI system controls the amount of fuel and air mixture that enters the engine, providing the right balance for optimal performance. The system replaces the traditional carburettor system, which relied on manual adjustments to get the right mix of fuel and air. EFI systems are computer-controlled and constantly monitor the engine's performance, adjusting the fuel/air ratio as necessary to maintain efficiency and performance.﻿ How Does an EFI System Work?﻿ An EFI system is made up of several components, including fuel injectors, a fuel pump, a fuel pressure regulator, and sensors that measure air temperature, engine speed, and more. These components work together to ensure the right amount of fuel and air is supplied to the engine. When the car is turned on, the system sends a signal to the fuel injectors, which release the fuel into the engine. The computer then calculates the amount of fuel needed based on factors like engine speed, air temperature, and more, adjusting the fuel/air ratio as necessary.﻿ Why Servicing Your EFI System Is Important﻿ Regular EFI servicing is crucial for optimal performance and efficiency. Over time, components can wear down or become dirty, causing the system to malfunction. A dirty fuel filter or clogged fuel injector, for example, can cause reduced fuel efficiency and engine misfires. By regularly servicing your EFI system, you can ensure that it is running smoothly and catch any problems early on.﻿ Common EFI Problems﻿ The most common EFI problems include reduced fuel efficiency, backfiring, and erratic idling. Reduced fuel efficiency is often caused by dirty fuel injectors or a clogged fuel filter. Backfiring can be a sign of a rich fuel mixture, which means too much fuel is being delivered to the engine. Erratic idling can also be caused by a rich fuel mixture or dirty sensors.﻿ Basic EFI Service Steps﻿ Basic EFI service steps include replacing the fuel filter, cleaning the fuel injectors, and checking and replacing the oxygen sensors. Visual Inspection: A highly skilled technician will conduct a meticulous visual examination of the Electronic Fuel Injection (EFI) system, scrutinising its multiple components for any indications of deterioration, harm or erosion Fuel Filter Replacement: To guarantee a consistent and uncontaminated fuel stream to the engine, it is imperative to replace the fuel filter when required. By replacing the fuel filter, the engine's overall performance is enhanced, resulting in improved fuel efficiency, lower emissions, and a prolonged lifespan Fuel Injector Cleaning: As time passes, fuel injectors may accumulate debris, ultimately impeding the fuel flow. However, a viable solution is to use a specialised cleaning solution that can restore the injectors' pristine functionality. In some cases the injector may be faulty and need replacing Throttle Body Cleaning: When it comes to ensuring your vehicle's engine runs smoothly, it's essential to pay attention to the condition of your throttle body. This vital component can accumulate carbon buildup over time, leading to restricted airflow and reduced engine performance Remember, maintaining your EFI system will help you avoid costly repairs, reduce harmful emissions, and keep your car running at its best so contact Custom Mechanics in Rockingham and give your EFI the TLC it deserves…

Custom Mechanics (AU05796) are the best choice to perform all your car air conditioner regas, repairs, inspection or servicing needs in Rockingham and the surrounding areas. In today's world, the vehicles we rely on for daily transport are sophisticated machines, boasting a myriad of advanced systems and mechanisms that necessitate consistent care and meticulous maintenance. One of the crucial components within these machines is the air conditioning system, which plays an indispensable role in maintaining comfort during our journeys.  Much like the engine, this system demands regular servicing and the timely replacement of essential parts to ensure it operates at peak efficiency. Neglecting these necessary tasks can lead to diminished performance and reliability, making it imperative to stay vigilant about the upkeep of the air conditioning system to enjoy a consistently comfortable and dependable driving experience. When refrigerant levels in your air conditioning system become low, either due to leaks or evaporation, the system's performance will suffer and it will have to work harder, ultimately increasing the amount of fuel needed to operate it. To prevent this from happening, it's crucial to regularly inspect the rubber seals for any signs of leaks or issues that may lead to refrigerant loss. By doing so, you'll be able to ensure your system remains in top working condition and you won't have to waste extra fuel to compensate for its deteriorating performance. It's important to have your car's air conditioning serviced annually to avoid costly breakdowns and ensure passenger safety. When harmful substances build up, it can be harmful to those riding in the car. A well-maintained air conditioning system can also save you money by reducing your fuel consumption. Think of it as an investment in your car's longevity and your wallet's health. Custom Mechanics  care about the environment and have Arctick Authorisation (AU05796) to reliably and responsibly conduct automotive air conditioning regas, repairs, inspection or servicing. Air conditioning FAQ How do air conditioners work? A car air conditioner system is composed of four essential parts : A belt-driven pump known as a compressor to compress and circulate gas. A radiator like unit called a condenser to redistribute heat and condense gas to a liquid. An expansion device, which could be a thermal expansion valve (TXV) or an orifice tube (subject to the kind of air-con system used). Some systems have an accumulator before the compressor to remove moisture from the refrigerant while TXV systems have a receiver-dryer before the evaporator performs the same crucial task. Both of these parts also store refrigerant. Car air conditioning is designed to pull the heat from the air within the car's interior area and transfer it outside, leaving only cooled or 'conditioned' air to be redistributed. Hot air is passed across a gas-filled evaporator, where the heat is easily absorbed by the refrigerant (in gas form), effectively removing the heat from the air in the car. The now heated gas is pulled through the compressor where it is further heated (via compression). The next stage involves the refrigerant being forced through the condenser to extract the refrigerant's heat quickly. The refrigerant, now condensed to a liquid, then moves through the expansion device (either a TXV or Orifice tube), which regulates the refrigerant's flow to the evaporator, changing the high-pressure liquid to a low-pressure mist (gas). A fan blowing over the evaporator's cold fins produces the cold air being blown into the car, and the entire process then begins all over again. Does the car air conditioner use more fuel? Yes! Your car air conditioning is using fuel. However, it's actually more fuel efficient to run car air conditioning than it is to have your windows down due to aerodynamic drag. If your air conditioning isn't performing its best, it may use more fuel to run. To avoid this, it's important that you have your air conditioning serviced regularly by professionals, like the ones at Custom Mechanics.  What's the cause of the bad smell in car air conditioning? The damp environment can promote microbes, bacteria and even fungus growth inside the evaporator core. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Although modern evaporator units tend to be more efficient, they have more fins, meaning an increased capability to trap moisture and allow for micro-organism development. How do I know my car air conditioning is due for a service? If you cannot remember when your air conditioning was last serviced, perhaps it's time to book in with the team at Custom Mechanics. You should also book in if: Your air conditioning system is blowing warm air There are damp patches or water stains under your dashboard Your car air conditioning system smells funny Your car air conditioning system is making strange noises There is weak air flow from the car air conditioning system Why does the car air conditioner need to be serviced? Car air conditioning is designed to pull the heat from the air within the interior area of the car outside, leaving only cooled or 'conditioned' air to be redistributed. This is achieved using a special compound called refrigerant, capable of readily absorbing heat as a gas and quickly losing heat as a liquid. The compressor needs the right amount of oil in the refrigerant to prevent it from seizing up. Should the air filters be jammed with dirt and bacteria, it will affect the entire system's performance, and it can even cause it to stop working altogether. On top of inhibiting air conditioner efficiency, dirty air filters can cause health problems. Being exposed to the elements and very diverse operating conditions and being used intermittently rather than being 'Always On' can cause decay of the hoses, connections and seals. A vehicle air conditioning system should be examined regularly to ensure there are no problems or refrigerant loss due to failure or leakage from these points. Simply by cooling the air in your car under normal running conditions, the air filters get dirty and intermittent use can cause seals to dry and crack, allowing them to leak. Even without leaks, the gas in a car air conditioning system will eventually begin to degrade or evaporate over time. It should be recharged as required to keep the air con system in peak running condition. How often should a car air conditioner be serviced? Your automotive air conditioning system needs to be examined once a year for any signs of problems with the seals, hoses and connections and confirm there is no refrigerant reduction over time. Regularly servicing your automotive air conditioner system keeps refrigerant at optimum levels meaning the system does not need to work as hard. This, in turn, protects the system from damage and minimises fuel expenditure. Can I service my own car air conditioner? Only qualified mechanics with the appropriate training, like the ones at Custom Mechanics, should attempt to service a car air conditioner. Specific licences are required to service or repair some types of car air conditioning systems, especially where re-gas (recharging of the refrigerant) is concerned. Strict guidelines and procedures must be adhered to when handling certain refrigerants, which must always be fully recovered and not allowed to escape into the atmosphere during servicing. Refrigerant can also pose serious health risks if mishandled. Specialist equipment is also required as the air conditioning system is under extreme pressure and must be pulled into a deep vacuum to remove any moisture, to avoid seriously damaging the system. You can find out more about licensing on the Australian Refrigeration Council (ARC) Website. Book your car air conditioning service with the experts at Custom Mechanics today!
