Fuel Injection Basics for Houston

All modern Houston vehicles come with fuel injection systems, so it's a topic Houston drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.

So how many fuel injectors does your vehicle have? There's one for each cylinder. So four, six or eight for most folks in Houston, TX. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.

Westside Automotive can help Houston drivers with a fuel injector cleaning service. What's the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It's important that the fuel is sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn't get burned as efficiently as it could. That robs performance and hurts fuel economy.

What about dirty fuel? How does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. It's tempting to shop for bargains in Houston with fuel prices as high as they are, but major brands in the Houston, TX, area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it's clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It's important to replace the fuel filter when your manufacturer recommends it. That's part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Houston drivers are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There's no room for dirt and gum in a precision part like that.

There are a lot of good products available in Houston, TX, that can clean fuel injectors. They're best used to prevent fouling in the fuel injectors. Many can't clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at Westside Automotive in Houston. But putting the cleaner in the fuel tank after you've had Westside Automotive take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your vehicle may be ready for a fuel injector cleaning.

Make Your Battery Last

Today's report from Westside Automotive is on vehicle 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 Houston 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 in TX. 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 vehicle 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 — 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 Houston area is that our batteries are often partially discharged. The biggest job the battery does is to start the vehicle. 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 have 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 there is a learning curve on how to do it right and it 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 Westside Automotive to clean it for you. We 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 Westside Automotive 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.

Why a Trip Inspection Is a Good Idea

At Westside Automotive we get a lot of Houston drivers asking about vehicle trip preparation. That's a big deal. You could be driving through mountains and deserts in some pretty lonely areas around TX, so it's important to know that the vehicle is up to the task and won't leave you stranded.

Smart Houston drivers plan ahead for a major road trip – and there are a lot of things to get ready. Where should you start? You could start with the tires. Look them over for tread wear and check to see that they are properly inflated. Take a quick test drive around Houston to see if you can feel any vibrations: Are the wheels in balance? Is the car tracking straight? Is the alignment ok? Come to Westside Automotive for a peace-of-mind trip inspection.

The next thing is a full service oil change to make sure all of your fluids are topped off and you have fresh oil for the trip. And if your car has over 75,000 miles/120,000 km, you may consider putting in the high-mileage formulation to clean harmful sludge deposits in the engine. 

How about your transmission and brakes? Have you had your transmission and brakes inspected in the last six months?

How are your wiper blades? There's nothing like not being able to get rid of the bug juice on a long road trip away from Houston.

Check your owner's manual for any other recommended services, and have Westside Automotive in Houston do the multi-point inspection before you head out on your trip.

Consider also having the coolant system serviced at Westside Automotive – you want to stay within the vehicle manufacture’s recommendations. If you're towing a trailer around TX you'll want to be keep in mind that you'll be going a long way under severe conditions.

A lot of Houston drivers overlook severe conditions like towing, TX summer heat or driving on dirt roads. Plan ahead for your next road trip – Westside Automotive wants you to get there and back.
