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. Many can’t clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at Autotronics of St. Peter in St. Peter. But putting the cleaner in the fuel tank after you’ve had Autotronics of St. Peter take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

A Clean Sweep (Fuel Injector Cleaning)

Your vehicle gets its power from burning fuel, usually gasoline, and it counts on something called fuel injectors to send gas to the engine in a spray that is easy to ignite. It’s a precise operation, and when it’s working well, you have plenty of power and an efficient engine.

But after time, contaminants in the fuel system may prevent the injectors from spraying like they’re supposed to. They can also shoot contaminants into the engine.

One sign that could point to dirty fuel injectors is a misfiring engine. Misfires can be caused by several things, so it’s a good idea to bring your vehicle to us so we can trace the cause. Another sign is that your fuel economy has gone downhill or your engine doesn’t have the “pep” it used to.

If we discover that your injectors are clogged or not working the way they should, we can clean them to get rid of those contaminants to restore your engine to its top performance. When you bring your vehicle to us, we will connect the flushing equipment, flush out the injectors and reassemble the system.

A good time to have fuel injectors inspected is when you bring your vehicle in for routine maintenance. An oil change is an ideal time to have a technician take a close look at your entire fuel delivery system.

When you have your fuel injectors cleaned, you may see your mileage go up, your engine performance improve, and your exhaust emissions decrease.

Maintaining Your Diesel in Cleveland

Diesel engines have been used extensively in Europe and Asia for many years. They haven’t been as common in Cleveland because of the high sulfur content in our diesel fuel. But the government is now mandating lower sulfur content and, as a result, we are going to see more St. Peter motorists driving diesel-fueled vehicles on the road, especially in passenger cars and SUV’s.

Diesels are popular in St. Peter because they get better MPG than gas-powered engines. They also last longer. Modern diesel engines are quiet and powerful. And if you associate diesel engines with black smoke, then you’re not up with the times. That smoke is a thing of the past.

Diesels don’t produce any more pollutants than gasoline engines. The pollution standards for diesel-powered vehicles are as strict in MN as for other vehicles.

Also, diesel engines can run on bio-diesel fuels as well as fossil fuels. Diesel fuel can be produced from vegetable oil or from cellulosic waste like wood chips and sawdust. In Cleveland, we may soon see bio-diesel produced from algae. These fuel sources will lessen St. Peter auto owners’ dependence on fossil fuels and may even become truly renewable and sustainable.

Diesel-powered vehicles perform as well as other passenger vehicles, also. Most Saint Peter people don’t notice a difference in driving one or the other. If you haul heavy loads or tow a trailer in Le Sueur, however, the diesel is a definite improvement.

So, you may be asking, if diesels are so great, why don’t all Cleveland motorists drive them? Surely there are disadvantages you haven’t told me about. That’s true. Diesel engines are heavier than gas engines, and they cost more in MN. The better fuel efficiency of the diesel engine is partially offset by the higher purchase price.

Because of higher fuel prices, diesel engines used to be more expensive to drive in Cleveland. But now, with higher volatility in the prices of both gasoline and diesel fuel in MN, that cost difference is less definitive. Whether a diesel or gas engine is more expensive for St. Peter drivers depends now on the current price of fuel in MN and how many miles you drive.

Consider also that diesel-powered vehicles have a high resale value in the Cleveland area, and the costs of owning and operating a diesel vs. a gas-powered vehicle in MN becomes a real toss-up.

Preventive auto maintenance for diesel vehicles has also become similar to that of gas-fueled vehicles in recent years. The major difference is that diesels require cleaner fuel, air and oil, so their filters are more expensive in St. Peter than those for gasoline engines. The engine air filter must be changed more frequently as well.

The costs for car care and repairs in St. Peter are similar. Wait, you may be thinking, but you just told me that filters are more costly and have to be changed more regularly. True, but that is offset by the fact that diesel engines have a much longer lifetime than gasoline engines. So if you are the type of owner who prefers to hang on to a vehicle for a long time, you will be more than rewarded with a diesel engine.

So if you have been looking for Autotronics of ST Peter auto advice on whether to switch to a diesel vehicle or stay with a gas-powered one, then we hope this helps. The answer as to which type of vehicle is better is that it depends on the St. Peter driver and their driving habits. Now that you know the facts, you can make an informed choice based on your own priorities and needs.
