Fuel Injection Basics for St. Peter

All modern St. Peter vehicles come with fuel injection systems, so it’s a topic St. Peter 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 St. Peter, MN. 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.

Autotronics of St. Peter can help St. Peter 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 St. Peter with fuel prices as high as they are, but major brands in the St. Peter, MN, 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 St. Peter 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 St. Peter, MN, that can clean fuel injectors. They’re best used to prevent fouling in the fuel injectors.

Cold Weather Vehicle No-Nos (Items to Avoid Storing in a Freezing Vehicle)

It’s always easier to leave a few things in your vehicle so you’ll have them on hand. But in cold weather, while it’s a good idea to carry items such as a phone charger, blanket and shovel, there are some things you shouldn’t store in your vehicle.

Medicines and drugs. Cold temperatures can affect the chemical makeup of some drugs. Avoid leaving them in a vehicle, especially those in a liquid form like insulin, eye drops and cough syrup.
Latex paint. They are water based, and when they freeze, they get lumpy and lousy. Your paint job will not be what you had in mind.
Cellphones and computers. Most of these have lithium ion batteries. If they get colder than freezing (0 degrees C, 32 degrees F), if you try to charge them, you’ll more than likely ruin the batteries.
Bottled water, soda, wine or beer. OK, here’s the scoop. All of these can freeze and split the container they’re in. Yes, soda, wine and beer will take a lower temperature to freeze than water, but all of these can easily freeze if the mercury plunges low enough. The problem isn’t when they’re frozen; it’s when they unfreeze, drip out of their containers and leave you with a colossal mess.
Musical instruments. Guitars are made of wood. When a guitar freezes and you bring it quickly into a warm room, you may hear cracking sounds that tell you that guitar will be not-so-gently weeping from the damage that can occur. The same goes for wind instruments and others. Don’t ever subject musical instruments to quick temperature extremes.

Take a little time and effort not to leave these things out in a frigid vehicle. You’ll likely spend far more time and money tending to the resulting consequences than if you’d just brought them inside in the first place.

Passing the Test (How to Prevent Emissions Test Failure)

Vehicle emission testing has become ubiquitous in North America and for a good reason. Clean air quality is important for the environment and all of us. Since vehicle emissions are among the main causes of air pollution, emission testing can alert you to problems in your vehicle than can be fixed so it won’t needlessly pollute.

Emissions tests are looking for certain toxic gases internal combustion engines produce, such as nitrogen oxide, particulate matter, non-methane organic gases and formaldehyde. Emissions control systems reduce these gases if they are working properly.

The best way to minimize pollution is to keep those vehicle systems working properly, and periodic inspection and maintenance is the key. So if you want to make sure your vehicle will pass an emissions test, it helps to know what might go wrong.

Let’s start on the easy one. Your gas cap could be loose, allowing vapors to escape into the atmosphere. The most common solution is to replace it. Or your air filter may be dirty. A dirty air filter may push your hydrocarbons pass the acceptable level.

Now to the more complicated things. The mixture of fuel and air in your engine may be tilted toward the “too much fuel” side. That could cause problems for your vehicle’s catalytic converter, a device that converts toxic gases from your exhaust into less toxic pollutants.

Your vehicle has a closed system that prevents fuel tank vapors from escaping into the air; it’s called the EVAP system. A technician can track down problems.

Vehicle engineers have gone to great lengths to minimize the amount of pollution your vehicle produces. Your vehicle’s manufacturer recommends how frequently those systems need servicing. Keep those systems in good shape and you’re likely to pass emissions tests with flying colors. Neglect them and you might find your vehicle failing an emissions test. When that happens, you’ll have to get the problems repaired before you can get back on the road.
