In very simple terms, a fuel injector is a valve that squirts fuel into your sedan 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 car driving down Lake Forest, Ladera Ranch, and Rancho Santa Margarita roads.

Most fuel injectors for gas engines are known in the Irvine auto industry 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 auto makers have recently introduced gas direct injection systems on some engines. They are now available at some Irvine 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 for gas-poor Lake Forest, Ladera Ranch, and Rancho Santa Margarita commuters. California motorists can expect to see more of it in the future.

High temperatures under your sedan hood and variations in Irvine 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 important for Mission Viejo drivers keep their fuel injectors clean.

Your Mission Viejo Accurate Auto Repair service center 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 sedan fuel system means that you will spend less on gas, enjoy strong performance and prevent costly Irvine repair bills down the road.

If you’re a quart low in your sedan, 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 Irvine area.

The same goes for dirty oil; it doesn’t reduce friction properly. The result is you get to watch those numbers at your local Irvine 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.

A lot of gas is wasted in the Ladera Ranch 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.

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 Accurate Auto Repair 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 Ladera Ranch service advisor at Accurate Auto Repair when a fuel system cleaning is recommended.

For those of you in Mission Viejo California 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 sedan 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 Accurate Auto Repair 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.

Today we’re talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. You need fuel to go, and the cleaner your fuel system, the more efficiently the fuel will burn. That means more power and better fuel economy.

A clean fuel system saves money at the pump. We guess you could say, it all starts and ends at the pump. One of the most important things you can do to keep your fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.

So buying cheaper gas can actually cost you in the long run. Now, most cars on the road are more than five or six years old. That means they’ve had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your engine. That’s the fuel filter’s job.

When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. That could do some damage. So you should have your fuel filter changed when recommended. Check your owner’s manual or ask your service advisor if your fuel filter is due for replacement.

The fuel then goes up into the throttle body. This is another area where varnish and gum can accumulate. A professional fuel system cleaning will use a combination of special cleaning chemicals and old fashioned swabbing to clean out the throttle body. Now, the fuel injectors are the last stop in the fuel delivery system.

It’s real important to keep those fuel injectors clean. The fuel injectors need to deliver a precise amount of fuel, at exactly the right time, in a particular spray pattern. They just can’t do that if they’re dirty. Dirty fuel injectors really rob power and waste fuel.

It is important for the fuel system proper, but there are a couple other things that will help keep your engine clean as well. Of course, air is mixed with the fuel before it’s burned. Dirty air means dirt gets into your engine, so you need to replace your engine air filter when it’s dirty.

The PCV value routes unburned fuel that escapes into the lower engine back up into the intake system to be burned. A sticky PCV valve needs to be replaced to make sure that system is working properly and the breather filter needs to be replaced if it’s dirty as well.

Do all these things and your engine’s air and fuel will be as clean as possible. You’ll get much better fuel economy and better power

.

You may have found yourself in the following situation: You go to get your oil changed and the service adviser at Accurate Auto Repair recommends you get a new engine air filter. You say yes, but because you didn’t know what an air filter is or what it does, but you were too embarrassed to ask.

First of all, you did the right thing by getting a new one. And, you should never be too embarrassed to ask for more information from any of our Accurate Auto Repair staff. It’s your money and you have a right to understand what you’re paying for.

Let’s review what an air filter does:

Air is the focus of this discussion. What is the air like outside in Mission Viejo right now? Can you see any smog? Is it full of pollen? How about dust? Anyone in California with hay fever can tell you that there’s plenty in the air that you can’t see. Well, it’s the engine air filter’s job to clean that air before it goes into your engine, to mix with the fuel and be burned. Without an engine air filter, the inside of your engine would be extremely dirty from all the gunk that was burned in the cylinders.

In fact, for every gallon of gas you burn, your engine needs 12,000 gallons of air. That little filter does a very big job. It’s no wonder that the air filter gets dirty and needs to be replaced. Think about a vacuum cleaner. When the bag gets full of dust and dirt, the vacuum doesn’t clean as well. It can’t move enough air to create good suction. A clogged engine air filter is the same way – the engine can’t get enough air to burn the fuel efficiently. That means less power and wasted gas.

That’s why your manufacturer has recommended that you change your filter at regular intervals. Of course the conditions you drive in will affect how quickly the filter gets dirty. If you drive where it’s very dusty or where there’s lots of pollen or pollution, you may need to change the filter sooner. The filter is easy to check visually, so your service technician can quickly make the call. He might recommend immediate replacement, or simply let you know that it is getting close and that you’ll need to replace it soon – like at your next oil change.

Because a severely dirty air filter hurts your fuel economy, many people find that a new air filter pays for itself in gas savings before the next oil change. They also make premium air filters that have been proven to increase your horsepower and torque. If more power is important to you, a high performance air filter is some of the cheapest horsepower you can buy.

The better your car breathes, the better it runs – kind of like people. And don’t worry – if you have a question or don’t understand a recommendation just ask.

There’s not much we can do about the price of gas in Mission Viejo California, but we do quite a bit about how much we use as we’re driving on our Mission Viejo streets.

Our driving habits can dramatically affect our fuel economy.

The first thing we can do is watch the ‘go-pedal’. Hard acceleration just sucks the gas. Gently leave stop lights and plan lane changes so you don’t need to floor it. That can save you hundreds of dollars a year.

Go a little slower on the freeway to Irvine. Once you’re going more than sixty-five miles an hour your fuel economy starts to drop dramatically. Leave early so you don’t need to rush to be on time. And cruise control is your friend – steady speed uses less gas.

Plan errands ahead. Make fewer trips by combining errands.

Hey at current gas prices, a lead-foot might as well be a gold foot.

Generally speaking there’s not a lot of dirt in our Mission Viejo California auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That’s because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your sedan is five years or older, it can actually have a fair amount of sediment built up.

That just means that the fuel filter has to work harder as your sedan ages. It’ll get clogged sooner and need to be replaced more often.

A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That’s because enough fuel is getting through around town, but when you need more fuel for speed, enough just can’t get through the filter. Obviously, that could be dangerous if your car or truck can’t get enough power to get you out of harm’s way.

For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.

This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don’t want to cause them damage just because you didn’t spend a few bucks to replace a fuel filter.

You know, in a way, the fuel filter can be the poster child for preventive maintenance. It’s a little part, it’s simple and it’s cheap to take care of. But if it’s neglected, it could lead to thousands of dollars of repair bills.

Those auto service schedules in your owner’s manual are there for a reason. If ever you don’t understand a recommended service, just ask your Mission Viejo service advisor at Accurate Auto Repair. We’ll be happy to explain.

A question for our Mission Viejo California motorists: How long have you been enjoying the romantic glow of your check engine light?

Hey, it’s not there to create ambiance; it’s a warning that something’s wrong. When your check engine light comes on get it checked at a capable Mission Viejo California service station.

Many conditions that cause the check engine light to come on affect fuel economy. Some very dramatically.

Always make sure you tighten your gas cap until it clicks. A loose gas cap can cause a false sensor reading that’ll make the check engine light come on.

If your date’s eyes are smoldering in the reflected glow of the check engine light, try to think of all the gas money you’ll save by getting it fixed. Give us a call when you are ready: (949) 472-4225

Something you’re going to be hearing a lot about around Mission Viejo, California is diesel engines. We’re not talking about semi-trucks and buses – We’re talking about diesel engine cars, pick-ups and SUVs.

Most people in Mission Viejo, California are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import auto manufacturers offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven’t been available in Mission Viejo, California. But that’s about to change.

In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in Mission Viejo, California so we are now ready to start seeing more diesel options offered over the next few years.

Why are so many interested in diesel engines? Well first off, diesel fuel is more energy dense. There’s more power in a barrel of diesel fuel than there is in a barrel of gasoline. That means better performance with better fuel economy.

Diesel powered vehicles get about 20 percent better fuel economy. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold with diesel engines?

If you think back to the late 1970’s and early 1980’s, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels are nothing like that.

They are quiet, clean – and very powerful. They’re so refined that many people can’t even tell they’re riding in a diesel powered car. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.

Another thing that intrigues the environmentally conscious is that it’s possible to use bio-diesel as fuel. Bio-diesel is made from vegetable oil – even recycled cooking oil from restaurants. Hybrid cars have gotten everyone’s attention these days. Look to diesel-electric hybrids in years to come to make a good idea even better.

Every year, manufacturers are planning more diesel offerings. Look for diesels in domestic light trucks, SUVs and passenger cars. Import marquees have plans to bring more of their outstanding diesel engines to Mission Viejo, California as well.

Now you should know that properly maintaining a diesel engine is somewhat different than a gasoline engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than gas fuel injection systems, so it’s very important to keep your fuel system clean with a diesel.

The good news is that your local Mission Viejo, California service center is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.

When we tell you to look for more diesels, you won’t be looking for smoky tail pipes as a clue. You also won’t be listening for that familiar big rig rattle. And, you certainly won’t be waiting for them at the stoplight, because modern diesels are as quick as their gasoline counterparts.

From all of us at AutoNetTV, ten four, good buddy.
