Fuel Injectors: Precision Auto Parts

Modern vehicles no longer come equipped with the old fashioned carburetor. Since 1990, all new vehicles are made with fuel injectors. A fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver, along with the precise time to deliver it. This happens thousands of times a minute.

Fuel injection is much more precise than the old method of using carburetors. That translates into better fuel economy and increased power. Practically all fuel injectors for gas engines are known as port fuel injectors, because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.

Some automakers have recently introduced gas direct injection systems for their engines. These systems inject the gas directly into the cylinders under very high pressure. Although they are also more complicated, direct injection technology promises greater power with improved fuel economy.

Your fuel injectors need to operate in a way that is deliberate and precise to maintain the performance of your vehicle. High engine temperatures along with variations in gas quality cause build up of wax, dirt, and carbon in your fuel injectors. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. The design of each engine requires a specific spray pattern from the fuel injector that might be altered when the injector is dirty. Dirty injectors prevent fuel from burning efficiently, resulting in poor fuel economy and loss of power.

At Loren’s Auto Repair, our service technicians can perform a fuel system service for you quickly and efficiently. A fuel system service is more extensive than a fuel injector cleaning. We recommend having the entire system services because the fuel can become contaminated in many ways between the gas tank and the fuel injector.. A fuel system service starts with a fuel filter replacement.

The fuel filter cleans the fuel as it leaves the gas tank. The various parts of the fuel intake system need to be cleaned at certain intervals to remove harmful buildup, deposits and varnish. And the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

At Loren’s Auto Repair Service we follow certain procedures for cleaning your fuel system that include state-of-the-art cleaning chemicals along with some old fashioned scrubbing. Proper maintenance of your fuel system means that you will spend less on gas, experience increased performance, and prevent costly repairs down the road.

Excellent service!! We are from Wisconsin and found Loren's on the web. They were able to fly in a new front axle and get us on the road in just 3 days at a very reasonable price. A quick follow up visit for adjustments allowed us to continue our vacation as planned. Absolutely recommend them. Mark was personable and knowledgeable, they offered a shuttle service and John was a great technician for our Xterra!!

This was the best car repair shop I have ever done business with. For being a young woman, who honestly doesn’t know a ton about cars, they were very thorough in explaining things and I trusted that they weren’t trying to rip me off based off my lack of knowledge or me being a young girl. Too many times have mechanics/car maintenance men try and rip me off. Once someone tried to charge me $180 for an oil change! Ridiculous. But not with these guys. They were awesome. My car broke down at a horrible time when I was busy with work and about to go on vacation. I had my car towed there and didn’t have time to stop by. They inspected it very soon after that, and got ahold of me. Then I was out of town for a couple weeks and they let me keep my car there. Even when I got back they had put it in the shop the night before so all the snow would melt. They were very friendly and even have a complimentary shuttle service when needed. I wish I could give the names of all the people who helped! Chad was awesome and answered all my questions and my dads when he called from a state away haha! The young girl who picked me up from the shuttle was super nice and has good people skills. If I ever have car problems again they will definitely be who I go to. Thanks guys!

Lorens never disappoints! They continually meet above my expectations. They met competitive rates, they have been upfront with charges and even gave me a loaner vehicle while doing their repairs. I will only ever use this shop. Mark at service desk is amazing and very knowledgeable!

I'm out here in West Glacier on vacation. During the trip, we hit a pothole and the exhaust started making a loud noise. We figured a hole had rusted open or something similar. We called Loren's Auto Repair to get it checked out, and they were awesome with recommendations. They let us explain the issue and then confirmed what we thought it was. They weren't able to get us in before we left, but they were kind enough to suggest a mechanic in town that possibly could squeeze us in. This conversation was a sign of trust and good business. The prices they quoted were fair and had excellent customer service. Thanks!
