Fuel Injection Basics for Newark

All modern Newark vehicles come with fuel injection systems, so it's a topic Newark drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.

So how many fuel injectors does your vehicle have? There's one for each cylinder. So four, six or eight for most folks in Newark, NY. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.

Union Street Automotive can help Newark drivers with a fuel injector cleaning service. What's the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It's important that the fuel is sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn't get burned as efficiently as it could. That robs performance and hurts fuel economy.

What about dirty fuel? How does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. It's tempting to shop for bargains in Newark with fuel prices as high as they are, but major brands in the Newark, NY, area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it's clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It's important to replace the fuel filter when your manufacturer recommends it. That's part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Newark drivers are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There's no room for dirt and gum in a precision part like that.

There are a lot of good products available in Newark, NY, that can clean fuel injectors. They're best used to prevent fouling in the fuel injectors. Many can't clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at Union Street Automotive in Newark. But putting the cleaner in the fuel tank after you've had Union Street Automotive take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your vehicle may be ready for a fuel injector cleaning.

Weather Station on Wheels (Vehicle Sensor Maintenance)

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool.

First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond.

Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient temperature sensor isn't working right, some symptoms are a malfunctioning automatic A/C or a temperature display that is way different than the app on your phone says it should be.

Your vehicle will also have sensors that measure your speed at each wheel.  They work with an onboard computer to measure slippage in any of the wheels so traction control and antilock brakes work correctly in case of slick roads.

Your vehicle can measure something called longitudinal and latitudinal acceleration, and it uses a yaw sensor to do it.  That helps it determine if you might be in an oversteering or understeering situation.  It's important because it works with your vehicle's brakes to apply stopping power to keep you in control.

A steering wheel sensor tells the vehicle's computers what the driver is doing with the wheel.  It also can work with those wheel sensors to measure how slippery the roads are, whether it be due to a wet (rain) or granular (gravel or sand) surface.  By sending different torque or braking to each wheel, it helps the driver maintain control.

More and more vehicles now have a rain sensor that can turn on the wipers automatically when they measure precipitation on the windshield.

So, you're driving your own weather station, and making sure all this data is coming in properly depends on how each component is working.  Regular service and maintenance on these systems is important to make sure they can do their job. Your rolling weather station can't predict the weather, but it can sure help you deal with it, so help it do its job right.

The Union Street Automotive Guide to Servicing Your Differential

Differential? What's that? And what's it for? I've been told by my service advisor that I need to get it serviced, but is that on the level?

Do these questions sound familiar? They're not uncommon for Newark drivers. A lot of us in Newark don't know what a differential is or what it's for. Every vehicle has a differential, and, yes, it does need to be serviced. In fact, it's more important to the operation of your vehicle than the air conditioner or windshield wipers.

A differential allows your vehicle tires to move at different speeds. This happens more than you think. The best example is when a vehicle is turning. The inside wheel travels a much shorter distance than the outside wheel during a turn. This means the outside wheel has to move faster than the inside wheel. Without a differential, your tires would hop and skip while turning. They would also lose traction in sand or snow.

The location of your differential depends on what kind of vehicle you drive. On a rear-wheel drive vehicle, the differential is located in the back. For a front-wheel drive vehicle, it is located on the front, but it is usually called a transaxle. Four-wheel drive vehicles have three differentials: one on the front, one in the back and one in the middle. This center differential compensates for differences in speed between the front and rear wheels.

Your differential contains strong gears that need to be protected from dirt, debris, water and other contaminants. A differential is sometimes referred to as a “gear box.” The work of these gears is to transfer power from the vehicle drive train to the wheels.

Your differential needs fluid to lubricate and cool the gears. This fluid, even though enclosed in the “gear box,” can get dirty because the gears grind down over time, releasing tiny bits of themselves into the fluid. Also, the additives in the differential fluid break down and need to be replaced. That's why preventive maintenance for your vehicle needs to include servicing the differential.

Your owner's manual can give you recommendations on how often to service your differential. But you should also consult with your friendly and knowledgeable Union Street Automotive professional. Union Street Automotive can give you some good auto advice on whether your vehicle needs to be serviced more frequently. For example, if you drive in hot or cold NY weather conditions, your differential will need to have its fluid changed more often.

Severe conditions will also affect your vehicle care routine and your differential. Check your owner's manual for a definition of “severe service” conditions that affect your vehicle. Examples may include driving with frequent stops and starts, a lot of short trips around Newark, hot or cold NY weather conditions and towing.

Off-roading is particularly hard on a vehicle's differential. If you are an off-roader, especially if you cross NY streams or waterways, it is important that you service your differential more frequently than the recommendations suggest.

Properly servicing your differential will extend its life and keep you out of Newark auto repair shops. A smooth ride is the result of proper preparation and smart choices.

That Squeal is Telling You Something (What Causes Squealing While Steering)

If you hear a squealing noise when you turn your vehicle, it's trying to tell you something is wrong.  After all, it never made that noise before, right?  The sound  you hear may becoming from a few sources.  Let's take a look (or a listen) to some of the possibilities.

First, you almost certainly have power steering in your vehicle. Without power steering, you practically have to have arms like Arnold Schwarzenegger to turn, so automakers have technology to assist your steering, either mechanically or electrically.  For a long time, the most common power steering has been hydraulic, using a belt to supply power from the engine that turns a power steering pump full of a fluid that helps you steer. 

Sometimes that fluid gets low because of a leak or some other problem.  The belt could wear out and start squeaking, and you might feel the steering start to become harder.  Your service repair facility can figure out the problem and offer some solutions.

Another cause could be in your suspension.  Some components may not be getting lubricated like they should.  Or you may be hearing your tires squealing when you are turning. 

Properly working steering is a huge safety factor for your vehicle's operation.  Your steering affects handling, vital to your well-being as well as that of drivers around you.  So take your vehicle over to your repair facility and have it checked out.  You'll be doing everyone on the road—including yourself—a big favor by listening to your vehicle. When it comes to steering, silence really is golden.  Get that squealing repaired and get back to safe driving.
