Fuel Injection: It Keeps Getting Better for CHICAGO Drivers

CHICAGO residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle 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 airbefore 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 vehicle engine.Direct injection engines burn fuel more efficiently than conventional vehicle 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.Wh ... read more

Service to Improve Fuel Economy

The price of gas in Illinois has got people in CHICAGO talking. It seems that CHICAGO folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy. First let's start with how we drive around Illinois. People in CHICAGO may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster, too. Another thing CHICAGO drivers can do is drive more slowly - but only when it's safe. Sometimes on the freeway we drive an ext ... read more

Fuel Injector Cleaning at Thom's Four Wheel Drive

In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle 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 vehicle driving down CHICAGO roads.Most fuel injectors for gas engines are known in the CHICAGO automotive community 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 have recently introduced gas direct injection systems on some engines. They are now available at some Illinois 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 ... read more

Fuel Injectors

The last new American vehicles sold in CHICAGO with a carburetor rolled out of the Illinois dealerships in 1990. Since then, all new vehicles here in CHICAGO, and nationally, have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for CHICAGO drivers. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.A few vehicle manufacturers have introduced gas direct injection systems on some engines recently. These systems inject the gas ... read more

Everyone from CHICAGO knows this makes sense.Some of us in the CHICAGO area carry a bunch of unnecessary weight, and I'm not talkin' what you see in the mirror.Guys: sports equipment and tools. Ladies: well, just take a look around the passenger compartment and trunk. I think my car has about 45 pounds of french fries on the floor.All that extra weight wastes gas as you drive between here and there, and everywhere else.Lose the junk and save some money....And you really only need one of those spare tires.

Clean Fuel ? Clean Performance for CHICAGO Drivers

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 vehicle engine.CHICAGO auto owners 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 vehicle 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 vehicle 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. CHICA ... read more

Fuel Filter Replacement

Hello CHICAGO resident! You would never like to drink a glass of mud, right? Well, your vehicle feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter's job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won't start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your vehicle will still run. But, then the contaminated fuel can clog your fuel injectors and allow particles into your engine.A vehicle with a partially clogged fuel filter might run well around CHICAGO, but sputter and strain on the because it's starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive in Illinois and the gas you buy. If you drive a lot on dirt or gravel roads in rural Illinois ... read more
