Pre-Ignition Catalytic Converter - How It Works?

By Sinclair Sonny

Despite the price of crude oil going down in price in the world market, there is still the issue of the world economic slowdown to be concerned about. Any amount of savings is welcome in these uncertain times, and one item in particular stands out when looking for ways to cut costs - the cost of gasoline. Today, people are clamoring for better gas mileage and asking car manufacturers to improve the fuel economy of vehicles.

The good news for those who cannot wait for the car manufacturers is that there are a lot of options available out there. There are many new developments in the area of bio fuels. There is now home made bio diesel, and home bio diesel conversions kits. But for those not keen on manufacturing their own fuel, there are other options such as Hydro Assist Fuel Cells, and one other promising system called Pre-Ignition Catalytic Converter (PICC) technology.

This technology is in the early stages of development. But even at this early stage it is already showing its promise - up to five times gas mileage increase.

In truth this is an old technology being used in a new way. Every factory made car has a Catalytic Converter, but is installed post ignition. It is installed in the car's emission system and is used to break down gas that is left un-burnt in the engine. The catalytic converter breaks the gas molecules into smaller particles that can then be incinerated in the tailpipe before being released.

PICC technology aims to use this system in reverse, breaking down the gas into smaller particles before sending it to the engine. The theory is that because the fuel is broken down before it reaches the engine, a more efficient burn will occur. That is, theoretically, how the PICC will work.

How can fuel savings be achieved, and how much?

With modern fuel injection technology, car manufacturers have been able to control the entry of just the right amount of fuel into the combustion engine to improve a car's fuel economy. With further tweaking and adding the PICC system, less fuel is needed to output the same amount of power from the engine, because the fuel is already primed to be burned more efficiently.

In one scientific test, a gas guzzling 318 V-8 Chrysler engine was run on a brand new state of the art dynamometer (the same testing equipment that Detroit uses) at 3,000rpms under a 50% load for an hour. Before the PICC modification, the engine used 18 pounds of fuel, which when converted approximates 22 mpg. Then researchers ran the same test with an engine with PICC modification and ran the engine under the exact same conditions for another hour. After the test, it was found the engine used only 2 pounds of fuel, a 9-fold increase in efficiency totaling a staggering 200 m per gallon, an amazing mileage from anyone's standard.

Even in these early developmental stages, PICC is showing a lot of promise. For the regular consumer it means more savings and funds for other expenses. For the world, it means reduction in greenhouse gases. And for America, it means less dependence on foreign oil. - 16752
