Fuel System Cleaning at Carsmart Auto Service in Marlborough 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 and 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 efficiency and loss of engine performance.

So it’s essential 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 MO fuel companies also deliver a more consistent quality of fuel than do bargain stations in the Dupo 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 Carsmart Auto Service in Marlborough 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 Carsmart Auto Service in Marlborough that will result in better fuel efficiency and improved vehicle performance.

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

Time Out: Suspension Problems in Marlborough

Your vehicle’s suspension system has two critical jobs: to prevent the passengers from getting tossed around inside the vehicle every time it hits a bump in the road and to keep the tires firmly planted on the road around every corner and over every bump.

To see your suspension system, you’ll have to look under your vehicle. Anything that connects the wheels to the vehicle’s frame is part of the suspension system. They’re heavy-duty parts that work hard while you’re driving and take a lot of wear and tear. Because of this, you should have your courteous Carsmart Auto Service service advisor look at them once a year as part of your preventive maintenance routine. A good time for an inspection is every time you get your alignment checked.

If your suspension is in trouble, you often feel it in how your vehicle drives. If the vehicle pulls to one side or wanders, if the steering is erratic, if your ride isn’t as smooth as it should be, or if your vehicle handles poorly, you should get a diagnostic examination of your suspension system. Uneven tire wear can also indicate worn parts in your suspension system. If your shocks are leaking oil then they definitely need to be replaced. All in all, if you don’t feel in control when you’re driving, go get your suspension inspected.

Shocks and struts wear out. Wheel bearings may need to be repacked every few years. Some parts of your suspension may need to be lubricated whenever you change your oil. Preventive maintenance is the key to keeping your vehicle under control. Good car care can prevent accidents for Dupo auto owners.

If you are in an accident, even a minor one, it can damage your suspension system or knock your wheels out of alignment. Even hitting a curb, pothole or large rock can damage your suspension. A wheel balancing or alignment won’t correct a suspension problem, and after any suspension work, you’ll may need to get an alignment.

At Carsmart Auto Service, we advise Marlborough motorists never to procrastinate critical repairs to their suspension system. A damaged suspension system can lead to loss of control of a vehicle in an emergency situation and serious accidents.

Potholes are unsightly nuisances around Marlborough, but they’re also a major cause of suspension damage for Marlborough car owners. To avoid this, Marlborough motorists should always keep their tires properly inflated. This gives the tires maximum resiliency. When you’re driving around the Dupo area, avoid potholes if possible. If you can’t avoid one, then slow down before driving over it. Slower speeds limit pothole damage. But if you’re a little late detecting a pothole, don’t brake on top of it. This will throw the vehicle’s weight forward and increase the damage.

The suspension system may not be pretty to look at, but it provides Marlborough auto owners with a safe, comfortable ride — as long as they maintain it properly. You don’t have to show it off, but you should be proud of it.

Make Your Battery Last

Today’s report from Carsmart Auto Service is on car batteries, why they die and what we can do to lengthen their life. Most of us have had a dead battery at one time or another. In fact, it would be very unusual if you hadn’t. You may be surprised to learn that only 30 percent of Marlborough vehicle batteries last for 48 months.

Now that’s an average. How long a battery lasts depends on many factors. You may not know that one of the biggest factors is the temperature where you live and drive around Marlborough. You might suppose that cold weather was harder on batteries because it takes more power to crank a cold engine, but the opposite is actually true.

Batteries in very cold climates have a life expectancy of 51 months as opposed to 30 months in very warm climates. The reason is simple: batteries are chemically more active when they’re hot than when they’re cold.

A car battery will actually start to discharge on its own within 24 hours in hot weather. It takes several days in cold weather. When batteries are left too long in a state of partial discharge, the discharged portion of the battery plates actually, for the lack of a better word, ‘die’. Recharging the battery will not restore the dead part of the battery plate.

One of the big problems for the way most of us drive in the Marlborough area, is that our batteries are often partially discharged. The biggest job the battery does is to start the car. It takes some time for the alternator to recharge the battery after starting. If you’re driving short distances, especially if there are several starts and stops, your battery may not fully recharge.

Another issue is that vehicles are coming equipped with more and more electricity hungry accessories like navigation systems, DVD players, CD and MP3 players, heated seats, heated steering wheels and so on. And we often plug in cell phones, computers and other gadgets. Combine that with short trips and it’s no wonder that our batteries are partially discharged.

Experts say we can extend our battery life by topping off the charge periodically using a good quality battery charger. You may’ve heard these chargers referred to as ‘trickle chargers’. They’re attached to the battery and plugged into a wall outlet to slowly bring the battery up to full charge.

Now there’s some science involved with how fast a battery should be recharged. If you buy a cheap manual charger, you’ll have to tend it. Frankly a learning curve on how to do it right and requires much attention. A computer controlled charger – or smart charger – monitors the process and determines the appropriate rate of charge. And it even stops charging when it’s fully charged. It costs more than the manual charger, but the automatic model is worth it.

The suggestion is to charge once a month in warm weather and once every three months in cold weather.

Another thing to avoid is deeply discharging your battery. Something like running the headlights and stereo with the engine turned off. That’ll take months off the battery life every time you do it.

Now, as we discussed, heat is hard on a battery. A dirty, greasy battery holds more heat. You can wipe off excess dirt with a paper towel or ask your service advisor at Carsmart Auto Service to clean it for you. Carsmart Auto Service can even test your battery and tell you if it’s time to replace it.

Batteries are fairly expensive, so taking a few steps to make them last longer is well worth it. Of course, the battery will eventually need to be replaced. Always make sure you get a new battery that meets the factory specifications for your vehicle. If you feel you need more battery capacity than what came with your vehicle, talk with your service advisor at Carsmart Auto Service about appropriate upgrades.

If you have a dead battery, be careful to inspect it before you jump start it. If the case is bulging, cracked or leaking, do not jump start it. Damaged batteries can explode or catch fire. And deeply discharged batteries can freeze. Do not jump start a frozen battery.
