  • Fuel Injectors

    May 7, 2017



    The last new American vehicles sold in MINNEAPOLIS with a carburetor rolled out of the MN dealerships in 1990. Since then, all new vehicles here in MINNEAPOLIS, and nationally, have had fuel injectors. In very simple terms, 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 as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for MINNEAPOLIS drivers. Virtually 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.

    A few vehicle manufacturers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure - hundreds of times the pressure of port injection systems. Although more complicated, direct injection technology promises greater power with improved fuel economy, so MN drivers can expect to see more of it in the future.

    As MINNEAPOLIS residents can see, the level of precision required of fuel injectors is very high. It's important that they operate properly in order for your vehicle to run right.

    High temperatures under your hood and variations in MINNEAPOLIS gas quality cause fuel injectors to become fouled with wax, dirt and carbon. 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. When injectors are dirty, the fuel doesn't burn as efficiently, resulting in poor fuel economy and loss of power. So it is important to keep your vehicle fuel injectors clean.

    Skilled service technicians at Affordable Transmissions in MINNEAPOLIS can perform a fuel system service for you. That is a fuel system service - not just fuel injector cleaning. That is because the fuel has a lot of ways to become dirty or contaminated between the MINNEAPOLIS gas pump and your fuel injectors. A fuel system service at Affordable Transmissions starts with a fuel filter replacement. This filter cleans the gas as it leaves the tank. The various parts of the fuel intake system need to be cleaned from time to time to remove harmful gum deposits and varnish. Finally, the fuel injectors are cleaned so that they operate properly for you and deliver the right amount of fuel at the right time.


    Our pros at Affordable Transmissions use a process for cleaning your vehicle fuel system that includes state-of-the-art cleaning chemicals as well as some old fashioned scrubbing. Proper maintenance of your fuel system means that you will enjoy strong performance and prevent repairs down the road.

    Higher Mileage Service Intervals for MINNEAPOLIS

    May 1, 2017



    MINNEAPOLIS drivers have probably noticed that the government mandates a lot of equipment on cars: emission devices and control computers, safety equipment like airbags and crash worthiness requirements. All of this is great for the motoring public in the MINNEAPOLIS area, but it does add quite a bit to the price of a new car.

    Because new cars are more expensive, MINNEAPOLIS residents are driving their old cars longer. The average car is now over nine years old. 68% of vehicles on the road have more than 75,000 miles/120,000 kilometers. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today's cars are up to the challenge - but they need a little help to keep on going.

    Some owner's manuals don't outline service requirements and schedules at higher mileage. Of course, that doesn't mean it doesn't have to be done. In fact, it's more important than ever for MINNEAPOLIS drivers to stay on top of routine auto maintenance for cars with more than 120,000 miles/190,000 kilometers. Just extend regular service intervals out: for instance a service that's recommended every 24,000 miles/38,000 kilometers should be performed at 24,000 mi/38,000 km; 48,000 mi/77,000 km; 72,000 mi/116,000 km, 96,000 mi/154,000 km; and on and on.

    Because of the additional stress older engines experience, the severe service maintenance schedule may be more appropriate than the regular schedule. Watch for leaks - seals and gaskets dry out over time and do not hold the fluids as well as they used to. If you don't already have one, it is more important than ever to get a good technician, like any one of the automotive professionals on our team at Affordable Transmissions. There are some services and replacements that are scheduled after you put some clicks on the odometer, like timing belts, valve train adjustments, suspension, anti-lock brake service, air bags, etc. And unexpected repairs down the road are just par for the course.

    Check for unusual sounds, smells or the way your car feels. These could be hints for MINNEAPOLIS vehicle owners that trouble is brewing. Better to catch it early before it turns into repair. Regular wash and wax will help maintain your car's appearance. One of the things MINNEAPOLIS drivers can do to really help a high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, transmission fluids and power steering fluids that are formulated for cars that have higher mileage.


    High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older vehicle engines are dirtier inside - and dirty engines contaminate their oil faster. High mileage oil has special additives that clean the engine, removing sludge deposits over time. The result is less stress on the engine, better fuel economy and excellent wear protection. Come into Affordable Transmissions in MINNEAPOLIS for a checkup.

    Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high mileage vehicles. So once you hit around 50,000 mi/80,000 km, consider stepping up to high mileage formulations. The fluids cost a bit more than standard fluids in MINNEAPOLIS because of the additional additives, but they can be worth their weight in gold in terms of preventing repair costs down the road.

    It does cost more for  vehicle owner's to properly maintain a higher mileage vehicle in MINNEAPOLIS - but it's much cheaper than a new car payment!

    How to Get Better Gas Mileage in MINNEAPOLIS

    Apr 9, 2017

    There is no escaping it: things work better when you take care of them. Something most of us in MINNEAPOLIS can relate to is our computers. You've probably noticed how they get slower and slower over time. It takes longer to start up and programs take forever to load. Eventually, many of us just get a new computer at our nearest MINNEAPOLIS computer store. But computer experts know that there are things you can do to delay the need for a new computer purchase. You can run utilities that clean off temporary files and clean your memory registry. You can optimize your hard drive and a number of other things.

    What you're doing is maintaining your computer to make it efficient. It's the same thing with your vehicle. You maintain it to make it more efficient. It works the way it was designed to and that means it uses less fuel while you drive around MINNEAPOLIS. And you save money.

    To help organize our discussion, let's think of things that rob us of fuel economy in two ways: increased friction and inefficient fuel combustion.

    Friction. Anything that increases friction increases drag or load on the vehicle engine. It has to work harder to overcome the drag – and that takes more fuel. The first thing that comes to mind is engine oil. Low oil means there's not enough to fully lubricate the engine so there's more friction. Dirty oil won't lubricate as well as clean oil. The same principles apply to transmission fluid. Getting your oil changed and transmission serviced on schedule at Affordable Transmissions will reduce friction and help you get better fuel economy.

    Another friction related problem is underinflated tires. When your vehicle tires are low on air, it's like driving on MN highways through sand – your vehicle has to work harder to move every mile. Check your tire pressure at least once a month.

    Wheels out of alignment and dragging brakes also increase friction. And your tires and brake pads will wear out much sooner as well. At Affordable Transmissions, we provide quality brake and wheel alignment services.

    Let's move on to Fuel. You have to get the right amount of clean fuel to the combustion chamber at precisely the right time. A dirty fuel system has varnish and gum interfering, and the fuel injectors may be unable to deliver the correct amount of fuel at the right pressure  and in the spray pattern — that the engineers intended. A vehicle fuel system cleaning at Affordable Transmissions will get all of that working right and really improve fuel economy.

    Replacing your fuel filter on schedule will help keep your fuel clean. Replacing a sticky PCV valve will allow unburned fuel from the engine to be returned to the intake system to be used. Replacing worn spark plugs will burn your fuel as efficiently as possible.

    All of these things can help you save money on gas at MINNEAPOLIS pumps.

    Give us a call.

    Fuel Injector Cleaning at Affordable Transmissions

    Dec 20, 2016

    In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected vehicle driving down MINNEAPOLIS roads.

    Most fuel injectors for gas engines are known in the MINNEAPOLIS automotive community as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

    A few have recently introduced gas direct injection systems on some engines. They are now available at some MN dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

    Although more complicated, direct injection technology promises greater power with improved fuel economy. MN motorists can expect to see more of it in the future.

    High temperatures under your vehicle hood and variations in MINNEAPOLIS gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

    When injectors are dirty, the fuel doesn't burn as efficiently resulting in poor fuel economy and loss of power. So it's wise for MINNEAPOLIS residents to keep their fuel injectors clean.

    Your technician at Affordable Transmissions can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

    Proper maintenance of your vehicle fuel system means that you will spend less on gas, enjoy strong performance and prevent repair bills down the road.

    To Save Gas Around MINNEAPOLIS: Keep up with Your Scheduled Service

    Nov 1, 2016


     

    One topic that hits the news in MN on a regular basis is the price of gas. The answer for some MN drivers is to buy a vehicle that gets better fuel economy. For those of us in MINNEAPOLIS who don't want to add a car payment to our monthly expenses, we need to improve our fuel economy any way we can.

    Following recommended service intervals by coming into Affordable Transmissions is one of the best ways people in MINNEAPOLIS can keep their vehicle running efficiently. That means better fuel economy. When you give it some thought, it only makes sense. Dirty oil or transmission fluid can't lubricate or clean. That means more drag which reduces fuel economy.

    Keeping up with scheduled oil changes and transmission services will save gas for MN drivers.

    Dirty engine air filters are another efficiency pirate. They rob your engine of enough air to effectively burn the fuel, so you need more gas to get the job done. Replacing a dirty air filter can pay for itself in fuel savings before the next oil change.

    You can imagine what dirty fuel injectors can do to your vehicle as you drive around MINNEAPOLIS. If your owner's manual recommends a fuel system cleaning, come into Affordable Transmissions and ask us to get it done for you.

    A simple, but very effective way for drivers to save gas is to keep their tires properly inflated. Low tires can cost you up to a mile per gallon/.425 kilometers per liter. Check your tire pressure when you gas up – or at least once a month.
