Liquid Injection Systems
Another way that people are looking to increase their auto gas milage in their vehicles is a system call liquid injection. These systems work by introducing water into the fuel system. Normally this system is used to prevent engine damage when the vehicle is required to work harder than normal.
When the water is introduced into the combustion chamberis pulls the temperature down to decrease the lose of fuel thru emissions therefore saving fuel. It works a lot like the fuel cooling device that increases the performance of the engine by condensing the fuel. Even tho these devices are normally used on vehicles that are worked harder than normal people are now putting them on regular vehicles to help save money at the pum.
