So the pilots would temporarily send water, or water and alcohol, to the combustion chamber to cool the air down and create more power to the engine. World-renowned AJ Hackett Bungy New Zealand’s original Bungy Jump will have you peering down at the majestic Kawarau River in Queenstown before leaping bravely towards the spectacular scenery below. Since then, some auto manufacturers have tried to use the same idea in vehicles, but with no proven results. The EPA had better results with a liquid injection system they tested, but not enough to significantly increase fuel economy. Some vapor bleed systems work by taking liquid fuel on its way into the engine, and mixing it with air from a pressure line. But do any of them actually work? The internal unit or units are connected to the outside unity with thin copper pipes and wires. The ionizer has a set of rubber clips that attach to each of the spark plug wires near the cylinder heads. To set up your AirPort as an Internet access point, start by connecting the Ethernet cable from your DSL or cable modem to the AirPort.

Meanwhile, in 1929, a group of US Army Air Corps fliers, led by then Major Carl Spaatz, set an endurance record of over 150 hours with a Fokker C-2A named the Question Mark over Los Angeles. This heat is removed by cooling to the ambient temperature in a heat exchanger, and then expanding by venting into a chamber. Others claim to change the molecular structure of the gasoline, heat or cool the gas, or just add air to it to make it last longer. But additives are just one category of products that claim to increase your gas mileage. The most common products that claim to add some extra MPGs onto your drive are the pour-in-your-gas-tank additives. The second claim is that they increase or restore gas mileage because of or in addition to, the first claim. In addition to the turbochargers heating the air, the sheer altitude of the planes meant that the air going into the engine was less dense than air near the ground and therefore there wasn’t as much of it to cool the engines.

Fighter planes would inject a water, or water and alcohol mixture, into the combustion chambers of their engines in order to cool the air their turbochargers were warming. Most residents have seen so many hurricanes, it takes quite an ominous storm for residents to heed even a mandatory evacuation order. You’ll see almost an entire shelf devoted to them at the automotive parts store and most of them have two basic claims. That bulge is called an expansion chamber, and it is used to increase the horsepower of the engine (see this page for a photo). As the exhaust gases expand into the expansion chamber, they create a vacuum at the exhaust port. As the shock wave of the exhaust pulse hits the end of the expansion chamber, it echoes back, pushing any fuel/oil/air that got pulled through the exhaust port back into the cylinder. As the piston moves down, it uncovers the exhaust port first to let most of the exhaust out.

Then it opens the intake port to let fuel/oil/air in. The pressurized air and fuel mix together in a chamber until the fuel becomes vaporized and is then released into a line that feeds into PCV manifold. They are typically installed on the positive crankcase ventilation (PCV) line or replace the idle-mixture screws. There are fuel additives, air bleed devices, liquid injection and even magnets all claiming to get more out every gallon of gas. The government does not endorse, nor does it officially approve, any product so be wary of any gas saving products with similar claims. Although one of these products showed a small increase in gas mileage, before you add an air bleed system into your car, consider the fact that the federal government considers some of these systems to be illegal tampering when installed. The Federal Trade Commission (FTC) specifically warns against products that claim to have government backing. Some of them claim to clean out your engine and as a result restore your engine’s fuel economy. Or, if they do clean the engine, the change is so insignificant that it has no effect on the engine’s mileage. There are lots of products in the automotive market that claim to increase or restore the gas mileage in your vehicle.
