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 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.  It ... read more

There's not much we can do about the price of gas in Rockville, MD, but we do quite a bit about how much we use as we're driving on our Rockville 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. Once you're going more than 65 miles an hour (105 kilometers per 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.

Your vehicle requires plenty of clean fuel to run. If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your vehicle engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts performance as you drive around the Rockville area. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.That's why all vehicles, including vehicles, come equipped with a fuel filter. The 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 Auto Clinic Care in Rockville.If your fuel filter is clogged, the vehicle engine can't get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a by ... read more

Rockville residents often ask the question: "Will using premium gas make my car run better?" The answer is simple. But first, let's talk about what exactly premium gasoline is.Different grades of gasoline have different octane ratings. Regular gasoline has the lowest octane rating and premium the highest. Most gas stations around Rockville, MD, also carry a mid-grade that falls in between the two. The octane range for the different grades of gas varies by region due to altitude differences.Engines require different octane ratings because of design differences.

A lot of fuel is wasted in the Rockville area by dirty fuel delivery systems in vehicles.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 Auto Clinic Care will leave your intake components 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 Rockville service advisor at Auto Clinic Care when a fuel system cleaning is recom ... read more
