Van Nuys Auto Repair & Service Center

Van Nuys car owners 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 fuel economy. The turbocharged version delivers 350 horsepower. Why the big difference in power?

Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the sedan engine.

Van Nuys motorists don’t need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your sedan engine will run.

Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your sedan ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.

The harder your fuel filter works, the more often it needs to be replaced. Check with your owner’s manual to find out how often it should be serviced and how long you can expect it to last. Van Nuys motorists should change it before it becomes clogged. Your family AutoAid & Rescue tech can help you with recommended fuel filter replacement schedules.

If your fuel filter becomes clogged, your sedan engine will sputter when you drive at highway speeds or when you accelerate rapidly. A clogged filter allows enough fuel to run the car at low speeds around town in Van Nuys, but when you need a higher flow of fuel for faster speeds, or if you need a sudden burst of fuel, you just won’t be able to get it through the filter.

Van Nuys motorists take note: A clogged filter is actually dangerous. If you need to accelerate suddenly out of the path of danger, you just won’t have the power to do it.

Fuel filters have a bypass valve. When the filter becomes clogged, the valve allows some fuel to bypass the filter so the engine can keep running – just not enough to be running well.

That means, though, that dirty, unfiltered fuel is entering your engine. Instead of clogging up your filter, that dirt is now getting into your fuel injectors where it can cause serious damage. Fuel injectors are expensive; fuel filters are cheap. It doesn’t seem like a difficult choice.

Fuel filters are the epitome of preventive maintenance. They are cheap and easy to change, but neglecting them can lead to pricey repair bills for Van Nuys drivers. Some fuel filters are inside the fuel tank and cannot be routinely serviced – your family AutoAid & Rescue service professional will be able to tell you if this applies to your vehicle.

Good car care means following recommended schedules for preventive maintenance, including changing your fuel filters. Take the auto advice offered in every owner’s manual and have your vehicle regularly inspected at AutoAid & Rescue. It may save Van Nuys auto owners money by preventing costly repairs, but it will also repay them in improved fuel efficiency, safety and peace of mind.

Van Nuys drivers know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your sedan 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 sedan engine.

Direct injection engines burn fuel more efficiently than conventional sedan 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 sedan 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.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the sedan 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 as well as delivering less power to the engine.

Van Nuys drivers should understand that 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. 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. 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, Van Nuys drivers will enjoy better fuel efficiency and their fuel injectors will last for a long time.

Hi Van Nuys motorists. Let's talk fuel injectors. A fuel injector is a valve that delivers fuel to a vehicle’s engine. It has to deliver the precise amount of fuel, to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.

Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.

The pressure in a fuel injection system varies depending on its type. Many gasoline sedan engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.

Vehicles have one fuel injector for each cylinder in the engine. Your vehicle’s control computer constantly monitors the engine and various sensors in the vehicle and adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle’s engine. Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel efficiency and loss of engine performance for Van Nuys motorists.

So it’s to Van Nuys motorists' advantage to keep their fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name fuel companies also deliver a more consistent quality of fuel to Van Nuys motorists than do bargain Los Angeles area service stations.

The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.

Van Nuys motorists should check their owner’s manual to find out how often they should change their fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle between Van Nuys, Sherman Oaks and Encino , your filter will need to be changed more often.

You can also purchase cleaners at AutoAid & Rescue that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won’t be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use. If your fuel injectors are gummed up, you can get a professional deep cleaning service at AutoAid & Rescue in Van Nuys that will result in better fuel efficiency and improved vehicle performance.

Good car care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.

Jon Sweeney / NBC News Max Sauberman, 18, from Millburn, N.J., checks his text messages as he waits in the passenger seat of his friend's car. Sauberman, who will be starting at Yale University in the fall, recently got his learner's permit but says he's been too busy to get his license. For the parents of today’s teens, getting a driver's license was a rite of passage often considered crucial to everything from dating to working -- and feeling like an adult. For today’s teens themselves? Not as much. The percentage of teens with a driver’s license has fallen significantly over the past few decades, and experts suspect there’s no one explanation for the shift. Instead, they cite a host of reasons, including everything from high gas and insurance prices to more of a willingness to let Mom and Dad drive ... read more
