Is there any possibility of cars running by water as its fuel or by substituting gas with water?
If the answer to the above question is “Yes”, then another basic question may arise. Continue reading ‘Is it Really Possible to Run Your Cars by Substituting Water Instead of Fuel?’ »
Unknown to most enthusiasts, not all subwoofers are created equal. Subwoofers depending on size, placement, and packaging have different characteristics unique to that setup. For example larger subwoofers such as 15 inch or 18 inch subwoofers require larger enclosures for the subwoofer to operate properly. This is partly due to the fact that the larger mass of a bigger sub needs more air inside the box to help the subwoofer move and oscilliate and dampen its oscillations correctly.
The rear wall of the subwoofer box acts as a reflection panel that the subwoofer uses to reflect and compound bass waves to help the subwoofer itself reach a higher peak response (or a harder hit). At the same time the air inside the subwoofer enclosure acts as an air cushion to help dampen the subwoofers return after it excursion and control its oscillation so that it does not distort the sound and is able to track the audio wave accurately; similar to the suspension on your car preventing never ending oscillations and controlling body shake so that the suspension can track the road’s surface.

Fuel pumps in fuel injected vehicles are mounted inside the gas tank. It’s a major job to replace it and these pumps are expensive. So before you replace one, you better do your homework. I’ve seen too many DIY mechanics make the assumption that their engine running problems are due to a bad pump. Several hundred dollars later, they still have the same problem.
If your diagnostics lead you to believe you have a fuel pump problem, here’s the proper way to check out the pump. First, perform a fuel pressure test. You’ll need a fuel pressure gauge and the adapters to fit your vehicle. Some auto parts stores rent this test gear. You’ll also need the specs for your vehicle. Check out a printed or online shop manual for those. Continue reading ‘Testing a Fuel Pump’ »
