Electric fuel pumps will experience problems with wear after many years of continuous service. Gradual loss of pressure and flow can result from the wear on pump vanes, rollers or gears. If the inlet filter sock lets sediment or rust get by then you will also have accelerated wear. This can even cause serious problems such as overheat and burn out if the pump becomes jammed with the sediment. Lubrication and cooling of the fuel pump only occurs when fuel is passing through it.
If you start having problems with your fuel pump then the first thing you should do is check the voltage supply and the electrical connections. You may simply just need to replace a fuse or loose wire. However, if everything is fine then you will need to run a measuring static output pressure and fuel delivery test to check the ability of the pump to deliver fuel. If your pump is not meeting manufacturer’s requirements after these test then you will need to replace the entire fuel pump.
When replacing your fuel pump always remember to disconnect the battery to prevent unwanted sparks during the replacement process. And always remember to drain the tank first. Before putting in a new fuel pump it is always a good idea to also replace the filter screen and use new o-ring and gaskets.
Always use the accelerator, brake pedals and other driving controls respectfully and smoothly. Sudden, swift and rough acceleration and sudden braking will harm your car’s fuel economy figures in the long run. Always combine multiple short trips for lowering overall fuel consumption of your car. Every time you run the engine, your car will automatically require fuel. This is why frequent and short trips are best combined into one or two longer ones.
Fuel economy depends heavily on how your car parts air while on the move. Fuel economy is highly affected by open windows even at high speeds. Keeping your window partly open is also a no-no in this regard. Higher drag will result in your fuel tank draining out much faster. As opposed to mainstream perceptions, you will save more fuel with your windows pulled up and the air conditioner running inside.
You should always take care to shift to the highest gear possible without any knocking of the engine. Fuel is consumed more while accelerating in lower gears. You should always shift down in case the engine is not pulling instead of just flooring the throttle. Shifting up at around 2,000/1,500 for petrol and diesel respectively is the best bet for getting sufficient speed and better fuel economy.
Clear excess baggage from your car including a deflated and unnecessary spare tyre, child seats which are not required anymore or even other bags and other stuff you usually carry. Keep your boot and interiors free clean and empty and you will certainly get fuel economy benefits.
Do not keep your car idling unnecessarily. This will only burn fuel without any traveling in the bargain. Suppose you are waiting for someone or at a traffic stop and you keep the engine running. This will give you 0 kmpl while fuel will be consumed all the same. Switch off the engine at traffic stops or while waiting somewhere.
Always get your oil and air filters cleaned as per the service schedule. Replacements are also necessary in particular cases. Sticking to your service schedule is a must since serviced and maintained cars consume less fuel.
Do not drive in rush hour if you want to save on fuel. Start a little early and plan your route carefully in order to avoid congestion as much as possible.
The simple trick to using less gas is not to drive less, but to drive smarter. And a smart driver (YOU) makes sure they are staying current with all their factory scheduled vehicle maintenance. This includes fluid changes like motor oil, coolant, windshield wiper, and power steering. But also includes services like tire balancing and rotation, brake pad inspections and replacements, cabin filter replacements, air filter replacements, comprehensive inspections, and more.
Aside from what your trusted mechanic can provide for your vehicle in terms of routine maintenance, there are many things you can do yourself to keep your ride in tip-top condition, allowing it to utilize fuel efficiently and perform for years to come.
Take initiative into your own hands with DIY car care. There are many duties you can implement on your own to continue vehicle maintenance in between regular scheduled mechanic visits. You can start by making sure your tires are always properly inflated. When they are not, your vehicle must work harder to assume the same level of performance, which uses more fuel. Also, be sure to periodically inspect the gas cap for damages. This can cause fuel to vaporize into the air.
Another way to use your fuel efficiently is to obey the speed limit and accelerate slowly. This also protects several components of your vehicle, allowing optimal performance and safety. Last, try emptying the trunk and backseat of unneeded materials. This can reduce the overall weight of your car, thus reducing the amount of gas it needs to operate.
Although there is no magical way to truly “drive more and use less“, with routine car care you can optimize your vehicle’s fuel economy, which essentially delivers the same financial gratification. Talk to your trusted automotive service technician about your vehicle’s recommended maintenance schedule. You may refer to your vehicle’s owners’ manual for additional information as well.
The most fuel efficient sport utility vehicle is the Audi Q5. This European car sells at a starting price of $35, 200, although the price can go up as high as $42,500 with the installation of additional features. In terms of its fuel efficiency, the Q5 is able to cover 20 miles with a gallon of fuel for urban driving, whereas a drive on the highway with a distance of 27 miles is possible with the same amount of fuel. This vehicle has a seating capacity of up to five adult passengers. With its spacious and comfortable leg room, passengers will not have to feel squeezed in into a narrow space. The Audi also sports the classic, sleek and elegant Audi look, reminiscent of the cool, sophisticated look of a European design. Besides its fuel efficiency, spacious interior and classy exterior, the Q5 is also highly praised for its exceptional driving experience.
Not far behind the Q5 is a SUV from Japanese carmaker Mazda, the Mazda Tribute. This one sells at a starting price of $20, 555, although the price can increase up to $27, 315. In terms of fuel efficiency, the Tribute can easily cover 23 miles in urban driving per gallon, whereas it covers an impressive 28 miles in highway driving per gallon. Overall, the vehicle has a fuel capacity of 17.5 gallon. Another aspect that is praised in the Tribute is its very user-friendly layout and controls, so drivers would not have to fiddle around trying to figure out what each control meant. Its smooth riding experience is also well approved by critics.
The final model is the original hybrid vehicle in the sport utility vehicle category, the 2005 Ford Escape Hybrid. For $27,000 the Escape impressively covers 36 miles per gallon for city driving, and 31 miles per gallon for highway driving. It can also accelerate from zero to sixty miles per hour in under nine seconds. As the first one in the market, the Escape may have had to face dozens of other competitors, but its smooth and easy driving experience is what makes it a crowd favorite.
The concept of hydrogen fuel cell is passing hydrogen gas (H2) through a membrane to produce electricity. However, there are some technical challenges with this kind of system. The main issue is storing of H2. Hydrogen gas has to be stored in a compressed state in a metal tank. This creates the problem of gas leakage that will endanger the driver. A solution to this issue is to use a H2 “on demand” system.
A hydrogen gas on demand system is basically using H2 generated from water to supplement gasoline fuel for a car. We know that water consists of 2 parts hydrogen and one part oxygen thus the name H2O. By attaching an electrolysis device to the SUV, H2 can be generated when power from the battery is turn on. The hydrogen gas generated can than be released into the engine air intake system to be mixed with conventional gasoline in the combustion chambers. The system can be switched on when the car is moving and switched off when it is idle. This will prevent any additional H2 gas produced from escaping into the car.
It has been tested and proven, by supplementing hydrogen gas into a SUV engine, it will improve gas mileage. This is because H2 is three times more potent than fossil fuel. The good news is to convert a SUV to use hydrogen fuel cell is not difficult. Anyone with some car maintenance skill can do it. All you have to do is to buy a step by step instructional guide and invest around $150 on parts and components for the project.
With US Automakers under the careful eye of investors and analysts they realize that they must adapt to the changing market. With fuel prices up and Japanese Automakers capturing another 4-5% of the United States Auto Market it is clear that car buyers want more efficient vehicles. It is quite evident with the 284 million dollar loss at Ford and the Delphi bankruptcy that it is time for a change. General Motors is even discussing dumping GMAC and has already made a deal with the Unions to cut back on some of those healthcare benefits and start discussing the under funded pensions.
As a sign to shareholders and analysts General Motors announced its plans to come out with a new small SUV, as well as introduce some new cross-overs, as many as 14 by 2010. Will it be enough? That is for time to tell, but it shows that GM is serious about fixing some of its ills. There will be smaller versions of the Saturn Vue, Chevy Equinox and the Pontiac Torrent. It is hard to say if this is enough to get buyers to take their names off the waiting lists for Hybrids at the Japanese Automaker Dealerships of Toyota and Honda. The soccer mom has spoken, but one does have to wonder if it is a little too late to bring GM out of a downward spiral as our nation enters a change in our business cycle.
Simply building smaller cars and SUVa may not be enough because it is more about the $100 monthly gasoline bill that the average American Family is looking at than merely the size of the vehicle. In fact people would drive around school buses if they got 50 miles to the gallon. Size does matter, but efficiency in the revolutions per minute is even more important, because that means fuel economy. Think on this.
