A New 2011 Bmw Activehybrid 7 Is Definitely Not Like The Toyota Prius

The 2011 BMW ActiveHybrid 7 happens to be a hybrid that will never remind you of a Prius in virtually any shape or form. Gas efficiency is the thing that you think of when you think hybrid nevertheless the BMW hybrid is not that fuel efficient. The 2011 ActiveHybrid 7 is the most fuel-efficient of the 7-series model, but its power steering is turned off by the idle stop feature, and it doesn’t work well in stop-and-go traffic. It is a technological powerhouse, and the hybrid platform adds power and fuel efficiency but also adds quirks to your driving everyday.

Using an electric powered motor in a hybrid shows that the gas-powered motor is smaller but in the case of the BMW, it is not. Although the standard hybrid uses the energy generated by the electric motor to cut down fuel consumption, BMW uses it to make the car move faster. The 2011 BMW ActiveHybrid 7 contains a double turbo direct-injection 4.4-liter V-8 engine which is the same as the fundamental BMW 750i The only difference is definitely the electric powered motor that’s powered through the 120-volt lithium ion battery pack. This makes the gas economy of the ActiveHybrid 7 much better than the 750i, and with a lot more horsepower in addition.

A lot of hybrids have the capacity to switch to all-electric mode even so the ActiveHybrid 7 does not do that. Rather, the system will create some boost during acceleration and the engine will shut down at a stop which is like the Integrated Motor Assist System of the Honda. When you are in the driver’s seat, you won’t even know that you are in a hybrid, but it has a blue area in the fuel gauge, which shows when the car is having electricity regenerated by its momentum. Once you arrive at a stoplight, you will know it’s a hybrid because the engine will go quiet and the tachometer drops to zero. Taking into consideration the size of the engine, it is shocking how smooth the engine comes back to life, when you take your foot off of the brake.

When you are waiting at a traffic light that is really prolonged, that is when the idle stop system works well, but not quite as well in stop-and-go traffic. The car will tend to shut down for 5 seconds at a time which can end up getting irritating after awhile. In addition, it takes getting used to the level of power, because the vehicle lunges forward with the slightest touch of the accelerator. Just how the car was created, it is not a green car but rather a car that uses the hybrid system to add more power while improving fuel efficiency somewhat.

The 2011 BMW ActiveHybrid 7 comes with the greatest gas mileage in the BMW 7 series family but it only gets 20 miles per gallon. That is good mileage for a top end luxury car but that is not really very good as a hybrid.

Fuel-Saving Merchandise May Not Necessarily Work

Everyone has their own way of managing the gas prices, which have continued to increase the last few years. Nevertheless, not every person is making the best decisions in their attempts to increase fuel efficiency. A good number of people are buying products that exclaim improved fuel economy without showing that it actually works. There appears to be many companies rendering these promises and simply stealing people’s money. With lots of these types of products on the market, one has to wonder if any of them work at all.

It is not that tough to be lured by the extravagant claims that these products make. Can these products really save on gas mileage and is there valid proof that it does work. Can these suppliers prove their claims or is the Environmental Protection Agency right when they say none of the products they have tested, increase gas mileage? Not one of these products have been certified as legitimate by the foremost authority in fuel economy. All of these products have anecdotal evidence but there many people who will feel ripped off. Though there hasn’t been serious scientific verification that these products work, they may seem to work for some people who have tried them.

How does one really know if these products help when you add them in your gas tank? It is likely you couldn’t tell because there are so many variables involved unless the improvements are absolutely drastic. You could find that you will be better off making changes to your driving habits instead of spending more money to save. You could save on fuel by simply maintaining the appropriate tire pressure which many people don’t do. You will discover it does not cost very much money to have the air filled in your tire and it’s totally free in some places. Even so, people choose to spend thirty times as much on some fuel booster than do a simple thing like that.

Another way to save on fuel is to change your air filters regularly. With clean filters, your gas mileage will improve. This is yet another area that people never look at when they want to find ways to save. Additional options include simply cleaning out the car trunk and making sure that you have the right motor oil for your car. You can also boost fuel efficiency by not using your air conditioning unit.

You have numerous inexpensive and totally free options to save on gas, there is no reason to buy a specialized product. To economize, you don’t always have to spend money.

When is It Hot Enough for a Synthetic Oil?

When is It Hot Enough for a Synthetic Oil?

Synthetic Oil

Synthetic Oil

“My supplier is pushing hard to move his synthetic gear oils into my operation. His position is that the units run too hot for long-term use of mineral oils. At what temperature should I switch to a Synthetic Oil lubricant for a non-circulated gearbox?”

First, the term synthetic is very broad, so we assume you are referring to lubricants that are formulated using polyalphaolefin (PAO) synthetic oil base.

Synthetic Oil

There is no single temperature point that dictates a time to move to synthetics. The decision is dependent on equipment continuous loads and shock loads, equipment availability for routine maintenance, criticality of the application, component life cycles, lubricant life cycles and failure modes among other things.

Generally, the rate of lubricant degradation doubles with every 18 degrees F increase in temperature. Once formulated with antioxidant additives, PAO-based lubricants have a lower baseline rate of oxidative degradation. At low temperatures, a PAO’s increased oxidative life may not be noticeable, particularly if you have to change the oil at some point for other reasons. At higher temperatures, the synthetic may last noticeably longer.

Typically, you begin to notice the extra life provided by a PAO synthetic oil above 160 degrees F. If it is above 180 degrees F, and especially 200 degrees F, the difference in oxidative life becomes quite apparent. However, the point at which a change to synthetic is justified is dependent perhaps on a handful of additional “program management” parameters such as:

1. Do you intend to run your gear oils with an appropriate use of filtration and oil analysis to support life-cycle extensions for many years?

2. Are you currently doing oil analysis and performing condition-based changes?

3. Do you have, and have you communicated to your lab, oxidation limits that flag impending oxidation problems?

4. Does the machine’s operating temperature vary a great deal (a PAO’s high viscosity index enables it to operate across a wider temperature range)?

5. Do you have an effective contamination control program in place that will enable you to fully exploit the PAO’s extended life?

With the appropriate management strategy, a change to a high-performance product can actually cost considerably less than the equivalent mineral oil product type. Outside of these considerations, somewhere around 165 degrees F represents the point at which you probably should begin to consider the use of synthetics for the sake of lubricant longevity, if not for the sake of reliability.

How To Change Your Timing Belt Yourself

By F Floyd Khumalo

The thing you predictably learn about as a car owner is that you will likely be called upon to conjure up money to fund repairs. The run of the mill stuff like oil changes and tuneups tend to be but one part of this; occasionally unpredictable things like changing belts crop up.

The timing belt will be one, but being aware what it is, is no grounds for knowing whether it needs to be changed. You most definitely don’t want to be surprized by a damaged timing belt when you’re out driving on the highway. You might well be pressing the envelope if you have had your automobile for some time. The life span of a timimg belt might be anything from 60,000 right up to 100,000 miles, which leaves a scary margin for error. You can learn this information from your owner’s manual, but who ever looks through it before something happens. While a timing belt might fail at any time, you are able to keep from being stranded by staying on top of things.

The timing belt turns the camshaft at a speed half that of the crankshaft. The camshaft will cause the intake and exhaust valves to widen and shut when the pistons go up and down in the cylinders. Without the timing belt, your automobile’s engine will never work. Generally a bad timing belt means considerable damage to the engine. Most people never even think about switching a timing belt until after it breaks. If you’re long distances away from a place of assistance, that could be very troublesome. You can’t really determine if it’s about to fail by any means, so the best policy is to replace it at regular, pre-determined intervals.

Replacing the water pump requires a lot of the same labor as changing the timing belt, so mechanics often recommend that the two jobs be done simultaneously. Your car’s water pump can fail at any time, or last the lifetime of the car. When it has to be replaced by itself the repair bill can be expensive, and the car out of commission for a few days. In case you consider yourself as a competent weekend mechanic, the replacement of a timing belt will not scare you. Just by looking at the details in an auto maintenance and repair manual, you should be able to replace the timing belt in a short space of time. It is possible to find the proper belt for your car from an online wholesaler like Timing Belt Pros. On the web, you can easily get relative prices, and doing the work yourself can save you a heap of money.

If you are capable to do your own work, you can avoid the expense of going to the repair shop of your dealer or a local mechanic. Of course you have to have your very own tools, or be able to rent them, along with the necessary abilities. Regardless of how you determine to do it, you need to keep up on the maintenance needed on your vehicle.

Your Timing Belt May Need Replacing And You’ll Be Able To Do It Yourself

Everyone who has ever possessed a car knows what it is like to have to come up with money for repairs. The average stuff like oil changes and tuneups are but one part of this; at times unpredictable things like changing belts crop up.

The timing belt will be one of them, but being aware what it is, is no grounds for knowing whether it needs to be changed. You most assuredly shouldn’t be surprized by a failed timing belt when you’re out driving on the highway. Now, if you have not acquired your car in the somewhat recent past, you could possibly be riding your luck a little. The life span of a timimg belt can be anything from 60,000 right up to 100,000 miles, which leaves a scary margin for error. If you had read your owner’s handbook, you’d probably have known this, but who does before something goes wrong? You can’t really anticipate when a timing belt is going to fail, but you can avoid a desperate situation by keeping yourself informed.

Precisely what a timing belt is used for is to turn the camshaft at exactly half the speed of the crankshaft. When the pistons move up and down inside the cylinders, the intake and exhaust managers open and shut because of the camshaft. A broken timing belt usually means your car is not going to budge. In some cases the car engine might be impaired or even ruined when there’s a failure with the timing belt. People typically only become aware of the timimg belt and the need to have to replace it after it has failed. If you are far away from a place of service, that could be very troublesome. As there is no actual way to examine the timing belt, you should just replace it at routine intervals.

Replacing the water pump demands a lot of the very same labor as changing the timing belt, so mechanics often recommend that the two jobs be done simultaneously. The water pump is an additional one of those peculiar items that can last forever or fail suddenly and without warning. Changing it alone entails a big expense, as well as being without your car for a few days. If you are a saturday mechanic, it’s possible you’ll feel relaxed replacing the timing belt yourself. With a reliable auto maintenance and repair manual to look through, you could change out the timing belt in no time. You’ll find online wholesalers, like Timing Belt Pros, who insure that it is easy finding the product right for your car. You can do comparitive shopping at different outlets, and by doing the job yourself, save a lot of money.

If you carry out the work yourself, you steer clear of the cost of hiring a mechanic or going to the dealer’s workshop. Naturally you do have to have the required tools, or be in a position to rent or borrow them, plus have the ability to do the job.

However, no matter if you or another person will do it, the timing belt on your car needs to be replaced regularly.

The Improved 2012 Honda Civic Hybrid

By Kathy Jenkins

The 2012 Honda Civic Hybrid has improved its gasoline economy from 41 mpg to 44 mpg and is now using a lithium-ion battery for energy. For automobiles that do not plug into the power grid, the Civic Hybrid has solidified its second-place position with the improvement in fuel economy. The rise in gas mileage helps make the Civic closer to the Prius and ahead of the Lexus CT 200h. Because the Civic Hybrid is not really a hatchback, Honda claims that it is the most fuel-efficient sedan on US highways.

The Integrated Motor Assist is going to be the fifth released hybrid powertrain system that the 2012 Civic Hybrid uses, which is thin, pancake like electronic motor/generator. The system is similar to Ford and Toyota where it assists the gasoline engine by being sandwiched between the transmission and engine. Even though the car can be operated by just electric power, it usually uses a mixture of both electric and gasoline engines. All engine parts still keep moving even when the car runs for a while on electric power. If the car stops the engine shuts off, and then starts up again when it is time to go, like other hybrid vehicles.

The new 2012 Civic Hybrid includes a larger gasoline engine, along with the shift to lithium-ion batteries. In spite of the boost from 1.3-liter engine to 1.5-liter four-cylinder engine, the horsepower from both electric and gas continue to be the same. The engine works by using the electric motor more often because the engine runs at a lower RPM due to the larger displacement, which results in a quieter ride. Every element of the hybrid system was modified, like the increase of the motor output from 15kw to 20kw. To better take care of temperature, it now uses plastic spacers, together with using more coils and magnets that are widely spaced. The horsepower with the motor has been accelerated simply by three horsepower to 23 horsepower.

The 20-kw Li-ion battery is a major advancement over the nickel-metal hydride battery that was used in the previous model, providing an extra 5kw of power with 30% less weight. Together with the battery’s 35% improvement in efficiency and the IMA system’s greater power, the Civic Hybrid is now offering the capability of using only electric motor power more often, in certain times of cruising at low speeds. Considering the move to lithium battery, the problems that affected the previous battery should now be resolved. Finishing the IMA system is going to be the continually variable transmission. The transmission works similar to a 10-speed bicycle which comes with a drive pulley and a driven pulley which are linked with a steel belt. It is a combination of a manual transmission and also a conventional geared automatic transmission.

With reliable advancements in fuel-efficiency and battery, the 2012 Civic Hybrid has certainly earned its honors. It is definitely giving the Prius a run for its money.
