Fuel Injection Keeps Getting Better for Du Quoin Motorists

Du Quoin residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.

There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.

Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.

For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.

Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.

Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.

When fuel injectors get dirty, their precision drops off. The spray pattern won't be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and fuel economy for Du Quoin drivers as well as delivering less power to the engine.

Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we're talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.

So keeping your fuel injectors clean is just good auto advice for Du Quoin residents. The best way to do this is to change your air and fuel filters regularly and practice other habits of good vehicle care and preventive maintenance at McPherson Automotive in Du Quoin. Cleaning additives in your fuel can also help.

If you do end up with gum or varnish in your fuel system, you'll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.

Fuel Saving Tip: Tire Pressure Saves Fuel in Du Quoin

Underinflated tires waste gas for lots of folks in the Du Quoin area. Think how hard it is to walk in sand – you just have to work harder because of the resistance. When your tires don't have enough air in them, their rolling resistance is dramatically increased and it simply takes more gas to get from here to there.

Always check your tire pressure when you gas up at one of our local Du Quoin service stations. If they're low – even just a little bit – bring them up to proper pressure. There's a sticker on the inside of your driver's door that gives the manufacturer's recommended tire pressure.

And don't rely on your tire pressure monitoring system to alert you to when you need more air. The TPMS system is set to warn you when pressure drops 20 percent below recommendations. That's severely underinflated and you needed more air a long time ago. And if you have a slow leak – get it fixed right away at McPherson Automotive.

Get some air and save some gas.

Always on Guard (TMPS)

One of the most important things you can do to keep your vehicle running safely is to make sure your tires are properly inflated.  If one or more is vastly over- or underinflated, that has the potential to cause major handling problems and may result in a dangerous accident.

All vehicles in recent years are equipped with Tire Pressure Monitoring Systems, or TPMS.  One system uses small sensors in the tires that continually check the pressure in each tire.  That sensor sends a signal to computers in your vehicle which turns on an instrument panel light warning of low pressure when at least one is very low. Or it may update a numeric reading on your instrument panel which gives you an approximation of how many PSI (pounds per square inch) of air is in each tire. 

Another system works with your antilock brake system to measure the size of your vehicle’s tires.  When one wheel is going faster than another, it will spin faster. A computer sees that and alerts you that tire’s diameter is smaller than the others and therefore must be underinflated.

No matter what system you have, it’s also helpful for you to know how much pressure each tire is supposed to be inflated to.  You can find that on a label on the driver’s side door sill. In addition, the TPMS system should not be used as a substitute for checking your tires with a tire gauge since the TPMS accuracy usually isn’t quite as precise.  Keep in mind that tire sensors can fail, so each system acts as a backup for the other. 

Since many vehicles these days don’t have spare tires, it’s good to know that your TPMS can warn you if you have a leak in one of your tires.  If you get a low-pressure warning, many systems will tell you which tire is low, so you can do your own visual check.  Often you can see if you’ve picked up a nail or a screw if it’s sticking out of the tread or near the sidewall.

Being able to receive an early warning from your vehicle of abnormal tire pressure may give you a chance to safely drive to a service center before your tire slowly goes completely flat (which can ruin the tire and badly damage the rim). It also may ultimately prevent you from being stranded somewhere with a flat tire or, most importantly, having a sudden blowout on the road.

How Does McPherson Automotive Know What to Recommend?

When you drop your vehicle off at McPherson Automotive in Du Quoin, they don't just poke around under your hood looking for stuff to do. McPherson Automotive professionals have lists and procedures they follow for different types of service. First of all, your Du Quoin service center will note the mileage on your vehicle. They'll then check to see what inspections and services the vehicle manufacturer recommends for a vehicle of your make, model and mileage. If you are a regular customer, they will also check your vehicle's history.

If the vehicle manufacturer's recommendations go beyond the services you've ordered, they'll let you know. They'll also indicate whether those services are urgent or if you can wait a while to take care of them. The McPherson Automotive pros won't do work that you don't agree to.

They will, however, perform inspections while they're servicing your vehicle. They'll check belts, filters and fluids. They'll check your windshield wipers for wear. They'll let you know if there's an urgent problem that needs taken care of, and they'll give you a heads-up about problems that might be developing. If repairs or services are in order, you are given options based on driving needs and budget.

You can think of it like a trip to the dentist for a check-up. The dentist will check if you've had x-rays recently. If not, he'll get your permission to take new ones. Then the hygienist will clean your teeth and check your gums. At the end, the dentist comes in and inspects your teeth. You'll be told if you need any work done, about problems that are developing, and if anything is urgent. You'll be given different care options and recommendations on where to get work done that is beyond your dentist's usual purview. Then you'll be sent to the front desk for appointments and paperwork.

These procedures make sure your teeth are in good working order and that you are apprised of any problems. Then you can make a decision as to what work you want done and when. McPherson Automotive in Du Quoin operates the same way. They want Du Quoin drivers to be able to make informed decisions about their car care.

Preventive auto maintenance is a lot like dental check-ups. Small problems can quickly develop into big ones. A cavity becomes a root canal. A dirty filter becomes engine damage. Skipping check-ups for either your teeth or your vehicle can lead to repairs.

McPherson Automotive follows industry guidelines. A part is replaced only if it can no longer perform its function, no longer meets its design specifications or is missing – or if you ask for upgraded performance. Your McPherson Automotive service advisor will recommend a part be replaced if it is showing signs that it will soon fail.

Dentists often offer services that go beyond routine care, such as teeth whitening. Service centers also offer Du Quoin drivers help with upgrades to a vehicle. They'll know what parts are needed and how to perform the work so that safety and performance aren't compromised. You can rely on the pros at McPherson Automotive for good auto advice.

The next time you're headed to the dentist's office, think about the vehicle you're riding in. Is it time for it to get a check-up, too?
