Fuel System Cleaning at The Muffler Doctor in KANSAS CITY for Better Performance

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

Fuel Saving Tip: Slow Down Around KANSAS CITY

There's not much we can do about the price of gas in KANSAS CITY, MO, but we do quite a bit about how much we use as we're driving on our KANSAS CITY 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.

By the Numbers: Tire Replacement at The Muffler Doctor in KANSAS CITY

Ever notice that your tire is covered with writing? It's like some hieroglyphic art form. Of course, KANSAS CITY drivers know that it's not just graffiti, but to most of us, it might as well be. Would you like to know what all those codes on your tire mean? It won't lead you to buried treasure, but it could help you make a better tire purchase at your local KANSAS CITY tire store.Prominently featured on your tire is a set of numbers and letters that looks something like this: 225 50 R 16 92 H. The first number is the width of the tire in millimeters, or the width between the sidewalls of the tire when it is fully inflated and not carrying a load. When KANSAS CITY drivers replace tires, they need to match this width number, or the tires won't fit properly in the wheel wells.The 50 is the aspect ratio of the tire, which is measured by taking the height of the sidewalls and dividing it by the tread width. If you drive off-road around the KANSAS CITY area, it should have a high aspect rati ... read more

Driving on bald tires is like playing roulette. Though you may be fine today, eventually your luck is going to run out.The Feds don't have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider 2/32 of an inch to be the minimum legal tread depth. Two other states, including California, consider 1/32 to be the minimum and six states have no standards at all. Call us at The Muffler Doctor; (just call 816-444-7100) to find out what your requirements are in the KANSAS CITY, MO, area.Since 1968, U.S. law has required that a raised bar be molded across all tires.
