Direct Fuel Injection Update From Lucas Auto Care

For those of you in Houston TX 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 European Car 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 Lucas Auto Care 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.

Considering an Alternative Fuel Vehicle In Houston?

There is a clear and vocal demand in Houston and nationally for a reduction in air pollution and our dependence on fossil fuels. This is what is driving the TX market for alternative fuel vehicles. There are a number of these vehicles on Houston area roads today, and many more being developed. Yet each of these vehicles has its own advantages and disadvantages. Houston drivers should learn what these advantages and disadvantages are before running out and purchasing one of these alternative fuel vehicles at your nearest Houston dealership.

Houston car owners should carefully research the car care before buying an alternative vehicle, as it may or may not coincide with the standards for gasoline vehicles. You should look at costs and gas mileage as well: these vehicles may help save our environment here in Houston, but that might not represent a savings to your wallet. You’ll need to decide what you can afford, and what will work for your lifestyle. Also, your choice of vehicle may be affected by what fuels are available in your Houston area. Switching to an alternative fuel vehicle is not a bad decision, but it should be a carefully considered one.

Flex Fuel Vehicles
Flex fuel vehicles can run on gasoline or on a combination of 85% ethanol and 15% gasoline. Because of the 85% ethanol content, this fuel is commonly called E85 in TX.

Ethanol is made from corn. So flex fuel vehicles lessen our dependency on fossil fuels. But they also raise the price of corn, which is a basic foodstuff in some areas of the world. Whether replacing fossil fuels with corn is a good idea is hotly contested right now.

Flex fuel vehicles do have lower harmful exhaust emissions than gasoline-powered vehicles. And in Houston, E85 is usually lower in cost than regular gasoline. When gasoline prices fall in TX, however, they can drop below the price of E85. This is to Houston motorists’ advantage, since the vehicle can run on either fuel, but it negates the benefits of lowered exhaust emissions and lower consumption of fossil fuels.

One piece of Lucas Auto Care auto advice before we move on: do not put E85 into your European Car unless it has an engine designed for flex fuels. Because of the high ethanol content in E85, engines need special seals and gaskets to function properly on this fuel. Running an ordinary engine with E85 can lead to gas leaks and fires.

Diesel
Diesel engines are nothing new on TX freeways, and many get great MPG. Diesel fuel can now be made from vegetable oil and other renewable sources. A diesel fuel made from algae will soon be on the market in Houston.

Natural Gas

Natural gas is less expensive than gasoline in Houston and burns more cleanly. Also, gasoline engines can be adapted to run on compressed natural gas, and many natural gas vehicles are already on Spring roads. You can even install a special pump in your home gas line to use to fuel your vehicle. If you are interested in converting your gasoline engine to run on CNG in Houston, ask your Lucas Auto Care tech about it.

On the other hand, an engine running on natural gas is not as powerful as one running on gasoline, and it will get lower gas mileage. Also, the tank you need to store natural gas is large—it takes up nearly the entire trunk of your car. Further, refueling stations are still few and far between in some TX areas, or even unavailable, in many parts of the country.

Hydrogen
Another alternative fuel that has enjoyed a lot of hype in Houston is the hydrogen cell. The natural appeal is that the only exhaust is water vapor. In other words, hydrogen represents a truly clean-burning fuel. But hydrogen vehicles won’t come into widespread use until refueling stations become widely available here in Houston and around the country.

Electric Vehicles
Electric vehicles were all the rage in TX some years ago. But their limitations were quickly realized by Houston car owners. These vehicles won’t come into their own until we find ways to improve their batteries. Currently, the cars have a short range before their power runs out, and can only be realistically used close to home. However, they are easy to recharge, since they can be plugged in at home, and there are many researchers working on improving the battery technology in these vehicles. They may yet be the vehicles of the future.

Hybrids
Hybrids have been one of the most successful alternative fuel vehicles here in Houston and throughout the county. A hybrid gets its name because it has both a gas or diesel engine and an electric motor.

There are two types of hybrids. The full-hybrid relies on the electric motor for power, but the gas (or diesel) engine generates power for the battery. Thus, while still consuming fossil fuels, it uses less of them than a standard automobile, and also reduces harmful pollutants. Also, it overcomes the range problem of the strictly electric vehicle.

In a mild hybrid, the electric motor assists the gas or diesel engine in powering the car. Thus, it uses more gasoline or diesel than full hybrids and has higher emissions. But mild hybrids are available in larger body models like full-size pickups and SUV’s.

A Note of Caution about Hybrid and Electric Vehicles
One last note before we leave the subject of alternative fuel vehicles. The battery in an electric or hybrid vehicle is not as tame as the one in a standard vehicle. They carry enough voltage to kill you. These are not do-it-yourself vehicles when it comes to preventive maintenance or car care. Only a trained technician should work under their hoods.

In today’s Lucas Auto Care auto post, we’re talking about fuel system cleaning. The first thing to know is how essential it is to have a clean fuel system. Houston drivers need fuel to go, and the cleaner the fuel system, the more efficiently the fuel will burn. That means more power and better MPG.

A clean fuel system saves money for Houston car owners at TX gas stations. We guess you could say, it all starts and ends at the pump. One of the most important things Houston drivers can do to keep their European Car 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 in TX can actually be more costly for Houston auto owners in the long run. Now, most cars on TX interstates 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 European Car 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 be dangerous. So Houston auto owners should have their fuel filter changed when recommended. Check your owner’s manual or ask your honest Lucas Auto Care tech 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 at Lucas Auto Care in Houston 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 important for Houston motorists 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 hurt fuel economy.

It is important for the fuel system proper, but there are a couple other things that will help keep your European Car 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 at Lucas Auto Care to make sure that system is working properly for Houston auto owners and the breather filter needs to be replaced if it’s dirty as well.

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

Can Your Car Last Another Year?

Have you checked out the price of new vehicles at Houston car dealers? Ouch! Add financing and insurance and – well a new ride may not seem so attractive. A lot of Houston, TX folks are hoping to make their cars last a lot longer.

Fortunately, with the current state of automotive engineering and manufacturing, there’s no reason a modern vehicle can’t be made to last for a 150,000 miles or more for smart Houston car owners.

The old adage: ‘a stitch in time saves nine’ is really true for Houston car owners when it comes to car maintenance. A great example is coolant service.

Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. Smart Houston drivers have their cooling system service taken care of right on schedule.

Ditto for your power steering system, brake fluid, air conditioning system, differential and transmission. Of course, oil changes should be done right on schedule to avoid the build-up of harmful oil sludge.
