Direct Fuel Injection Update From Aero Automotive



For those of you in Marietta GEORGIA who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.

For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same gas mileage. The turbocharged version makes over 350 horsepower.

So what are the differences from a conventional engine?

The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it’s then drawn into the engine with the air.

With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.

First, the fuel is squirted in at hundreds of times more pressure, so it’s atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.

Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can’t do its job as well. That means less power and worse fuel economy for your suv and can lead to damaged fuel injectors.

Replacing fuel injectors isn’t cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we’re talking mortgage payment-range to replace a set of diesel injectors.

A professional fuel system cleaning from Aero Automotive gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they’ll last a long, long time.

Fuel Injection Keeps Getting Better For Marietta Motorists

Marietta motorists 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 gas mileage. 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 MPG.

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 gas mileage for Marietta motorists 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 Marietta car owners. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance at Aero Automotive in Marietta. 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: Marietta Tune Up



Have you ever gone to Atlanta to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That’s why they tune up together.

Fuel Economy Now this is no surprise; I’m going to relate the orchestra to your car. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.

We call this, (ta-da) a tune-up. When an orchestra’s out of tune you get a bad concert. When your vehicle’s out of tune you get bad performance and bad fuel economy.

So check your owner’s manual for recommended tune-up intervals. Or ask your Marietta service advisor at Aero Automotive what he thinks.

…Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.

Fuel Injectors



The last new American cars sold in Marietta with a carburetor rolled out of the GEORGIA dealerships in 1990. Since then, all new vehicles here in Marietta 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 MPG and more power for Marietta auto owners. 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 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 efficiency, so Atlanta motorists can expect to see more of it in the future.

As Marietta auto owners can see, the level of precision required of fuel injectors is very high. It’s essential that they operate properly in order for your car to run right.

High temperatures under your hood and variations in Marietta 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 efficiency and loss of power. So it is important to keep your suv fuel injectors clean.

Skilled service technicians at Aero Automotive in Marietta can perform a fuel system service for you. (Visit http://aeroautomotive.com/contact/.) 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 Marietta gas pump and your fuel injectors. A fuel system service at Aero Automotive 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 Aero Automotive and deliver the right amount of fuel at the right time.


Your honest Aero Automotive technician uses a process for cleaning your suv 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 enjoyed improved fuel economy, enjoy strong performance and prevent expensive repairs down the road.

Fuel Saving Tip: Dirty Oil In Your Marietta SUV

If you’re a quart low in your suv, there isn’t enough motor oil to lubricate your engine properly. The extra friction causes drag that reduces fuel economy while you’re driving around the Atlanta area. Clean Oil for your suv The same goes for dirty oil; it doesn’t reduce friction properly. The result is you get to watch those numbers at your local Atlanta gas pump rolling higher and higher. The transmission also needs the proper amount of clean fluid to do its work. When it’s in need of service, the transmission drags your fuel economy down. So keep it clean and give yourself a fighting chance.

Alternative Fuel Vehicles In Marietta GEORGIA



Let’s talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions to our Marietta environment, automakers will have a number of alternatives for us very soon.

For instance, Flex Fuel vehicles are already available in the Atlanta area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn.

The benefits are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower fuel economy and that when gas prices are low, E85 can be more expensive than straight gasoline.

You should only use E85 if you have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires.

Diesel engines have been around the Atlanta area for a long, long time. Modern diesels are very refined and fuel efficient. Diesel fuel can be made from renewable sources like vegetable oil, too. Diesel fuel from algae and sunlight is reported to be pretty close to being commercially viable.

There are also a number of natural gas vehicles on our Atlanta roads. Gasoline engines are adapted to run on compressed natural gas. It’s less expensive than gasoline and burns very cleanly. You can even refill it with a special pump from your gas line at home.

Natural gas engines don’t make as much power and don’t get as good of mileage, but they cost less per mile to run. The big inconvenience is that the tank that holds the compressed natural gas takes up a lot of room; even your whole trunk! And there may not be places to refuel on a road trip from Atlanta.

Plug-in electric vehicles are now available in our Atlanta area. Battery technology is the limiting factor right now. Electric cars have a limited range and are really best for use close to home. As battery technology advances, electric cars will perform closer and closer to conventional power plants.

That brings us to hybrids. There are a bunch of hybrids on our Atlanta roads, with more to come. Hybrid technology combines internal combustion engines with electric motors.

A mild hybrid has a regular gas or diesel engine that’s assisted by the electric motor. The electric motor can propel the vehicle by itself up to a certain speed under gentle acceleration. There are mild hybrids in full-sized pickups and SUVs. They deliver city fuel economy similar to their highway ratings.

A full hybrid will rely primarily on the electric motor for power. It’ll have a small gas or diesel engine that generates electricity for the batteries.

Another breakthrough technology is hydrogen fuel cells. Fuel cell vehicles use hydrogen to generate electricity. Several global car makers have prototypes on the road. The appeal is that the only thing that comes out of the tail pipe is water vapor. It’ll take some time to build a national infrastructure of hydrogen fueling stations before there’s widespread use.

A quick word about safety around hybrid and electric vehicles. Unlike the battery in your current family car, these carry enough voltage to kill you. Never mess around under the hood or with the batteries or electrical wiring. Your Atlanta service technician at Aero Automotive is trained to safely disable the flow of electricity before performing maintenance or repairs on the vehicle.

Hybrids are really not do-it-yourself vehicles unless you’re specifically trained on hybrid systems.

Fuel Saving Tip: Fuel System Cleaning Near Marietta GEORGIA

A lot of gas is wasted in the Marietta area by dirty fuel delivery systems. Let’s start at the tank. The gas tank gathers dirt, rust and sediment over the years. That’s why there’s a fuel filter to clean the fuel after it leaves the tank. A dirty filter will rob the engine of the clean gas it needs to run efficiently. Aero Automotive Fuel System Cleaning The fuel intake components get coated with gum and varnish over time. This results in fuel being delivered inefficiently and some of that gunk getting into the engine. A fuel system service at Aero Automotive will leave your intake as clean as a whistle. The big fuel thief is dirty fuel injectors. They deliver fuel to the engine at a specified pressure and in a particular spray pattern. When they’re clogged, the fuel doesn’t get atomized the way it’s supposed to and doesn’t get burned as efficiently. See your owner’s manual or ask your Marietta service advisor at Aero Automotive when a fuel system cleaning is recommended.

Give Your Engine Clean Fuel With A New Fuel Filter From Aero Automotive

Your suv requires plenty of clean fuel to run. If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your suv engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts gas mileage and performance as you drive around Atlanta. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber. That’s why all vehicles, including suvs, come equipped with a fuel filter somewhere between the engine and the fuel tank. Give Your Engine Clean Fuel With A New Fuel Filter From Aero AutomotiveThe job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at Aero Automotive in Marietta . If your fuel filter is clogged, the suv engine can’t get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your suv engine running, but doesn’t protect it from contaminated fuel. You may find that you need to change your fuel filter at Aero Automotive more frequently as your suv ages. Over the years, additional sediment and rust accumulates in the fuel tank and can be drawn into the fuel system. Your fuel filter stands guard at the gates to your engine to protect expensive parts and to maintain performance and fuel economy.
