Fuel Injectors

The last new American vehicles sold in Porter with a carburetor rolled out of the TX dealerships in 1990. Since then, all new vehicles here in Porter, and nationally, have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for Porter drivers. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.

A few vehicle manufacturers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure - hundreds of times the pressure of port injection systems. Although more complicated, direct injection technology promises greater power with improved fuel economy, so TX drivers can expect to see more of it in the future.

As Porter residents can see, the level of precision required of fuel injectors is very high. It's important that they operate properly in order for your vehicle to run right.

High temperatures under your hood and variations in Porter gas quality cause fuel injectors to become fouled with wax, dirt and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. The design of each engine requires a specific spray pattern from the fuel injector that might be altered when the injector is dirty. When injectors are dirty, the fuel doesn't burn as efficiently, resulting in poor fuel economy and loss of power. So it is important to keep your vehicle fuel injectors clean.

Skilled service technicians at Houston ADAS in Porter can perform a fuel system service for you. That is a fuel system service - not just fuel injector cleaning. That is because the fuel has a lot of ways to become dirty or contaminated between the Porter gas pump and your fuel injectors. A fuel system service at Houston ADAS starts with a fuel filter replacement. This filter cleans the gas as it leaves the tank. The various parts of the fuel intake system need to be cleaned from time to time to remove harmful gum deposits and varnish. Finally, the fuel injectors are cleaned so that they operate properly for you and deliver the right amount of fuel at the right time.

Our pros at Houston ADAS use a process for cleaning your vehicle fuel system that includes state-of-the-art cleaning chemicals as well as some old fashioned scrubbing. Proper maintenance of your fuel system means that you will enjoy strong performance and prevent repairs down the road.

Fuel System Cleaning at Houston ADAS in Porter for Better Performance

A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.

Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.

The pressure in a fuel injection system varies depending on its type. Many gasoline engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.

Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It also adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle's engine.

Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel economy and loss of engine performance.

So it's important to keep your fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name TX fuel companies also deliver a more consistent quality of fuel than do bargain stations in the Porter area.

The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.

Check your owner's manual or ask the pros at Houston ADAS in Porter to find out how often you should change your fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle, your filter will need to be changed more often.

You can also purchase cleaners that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won't be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use.

If your fuel injectors are gummed up, you can get a professional deep cleaning service at Houston ADAS in Porter that will result in better fuel economy and improved vehicle performance.

Good vehicle care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.

What Is an EGR Valve? (EGR Valve Service)

If you've ever felt your vehicle hesitate, go, then hesitate again, you might think there's something wrong with the transmission.  After all, it's not moving smoothly  down the road.  But there are plenty of malfunctions that can cause those symptoms, one of them being something you may have never heard of: the EGR valve.

EGR stands for Exhaust Gas Recirculation. It's a system that channels small amounts of exhaust back into the engine to cool down the cylinders and reduce polluting gases.  Those include nitrogen oxides that can cause smog. The EGR valve regulates how much of the vehicle's exhaust gas is recirculated. After years and long distances traveled, that valve can get clogged or fail. Sometimes the EGR valve can stick open.  When the EGR valve isn't working properly, your vehicle can start releasing those nitrogen oxides and pollute the air.

The symptoms of a malfunctioning EGR valve include:

• Engine losing power
• Engine idling roughly
• Pinging and knocking sounds in the engine
• Stalling and hesitation
• Fuel economy decreasing
• Check Engine light illuminated

Depending on its condition, the EGR valve can be cleaned or it may need to be replaced.  Consult with your service advisor to see what options are recommended to you.

The EGR system is part of your vehicle's pollution and emissions control equipment. If you care about keeping our planet's atmosphere clean, you'll want to make sure it's doing its job—for everyone's benefit.

Idle Talk about Engines (Causes of Rough Engine Idling)

When you slow down at stoplight, your vehicle's idle should be smooth as silk.  But what happens when the engine is missing or idling roughly? That's your engine's way of telling you, "Hey, I've got something wrong with me and if you don't get someone to find out what it is, I may not start the next time you turn the key."

You can help your service facility if you can describe the problem in detail.  Here's a list of things to make a note of:

• When is the problem happening, when the engine is cold or when it's been running for a while?
• Does the rough idling occur when I'm accelerating or when I'm going at a steady speed?
• Does it happen at high speeds?  Does it happen low speeds? Does it happen at both?

Make sure you describe the problem in as much detail because it will help a technician diagnose the problem.

One of the first things they'll check is how the spark plugs are firing.  Modern iridium plugs are supposed to last a long, long time.  But they CAN eventually wear out.  Inspecting the firing end can help the technician figure out the root of the problem.  Corroded or worn out spark plug wires, too, can contribute to an idling irregularity. 

There are other potential problem spots, too.  The technician may check the ignition coil, timing piston rings, valves and cylinder walls. 

If the mixture of air and fuel isn't correct, that may affect how smooth your vehicle is running.  Your service facility is equipped with diagnostic equipment that helps them pinpoint the problem.  Once that idle is smoothed out to the way it used to be, you'll be the smoothest operator on the road.

Beware of Cheap Tires in Porter

Do you like to shop for shoes in Porter?
When buying a running shoe, is quality important?
Does durability matter as long as the shoes look fabulous?
Would you rather have one pair of long lasting shoes or two pairs of lower quality shoes at the same price?

Is the warranty important when buying tires?

Porter drivers should also think about the safety aspect of tires. The tires do a lot of work – they carry the weight of the vehicle and you and your passengers. You want to be sure they hold the road and provide good traction on TX freeways and surface streets. If you carry heavy loads or tow a trailer on TX highways, the tires need a high load rating.

Ask your friendly and knowledgeable Porter tire professional at Houston ADAS. I think it's important that Porter residents understand the effect of price on a tire's quality, performance and durability. When I was a kid, my dad would say, “Pay twice as much and buy half as many.”

The same principle applies to tires. The major tire brands that you're familiar with in Porter are known as Tier 1 tires. These tires are high quality and well-engineered. Comparable vehicle Tier 1 tires are usually priced similarly.

Stepping down, you come to private label tires. Some large TX tire store chains carry tires with their own brand. It's important to know that most private label tires are built by the same Tier 1 companies that you are familiar with – so you are pretty safe in choosing them. To be sure, you can ask your Houston ADAS tire professional which manufacturer makes their private brand.

The lowest priced tires on the market in Porter are Tier 3 tires which are usually imported from China or South America. Since you get what you pay for, you can't expect a Tier 3 tire to deliver the same performance and durability as the others.

What's the difference in the tires with high mileage warranties? It's the rubber compounds and the amount of tread material. As you might expect, you'll pay more for the longer-lasting tire.

Your tires are the only parts of your vehicle that touch the road. You're only as safe as your tires are well built. Buy value – not price.

Give us a call.
