Why hydro assist works, and PICC
« on: March 18, 2008, 07:11:36 PM »
Most people say it's because the fuel is burned more completely, I don't think that's were most the boost is coming from. I wrote it all out on my website, so I'll copy and past from there. The concept of the PICC works, though the people selling them may not be trustworthy.

PICC's work by breaking the hydrocarbons down into hydrogen. (more on why that helps later)

MIT and some top car part manufactures are developing the same technology.

It uses 200 watt's that's about the same as hydrogen generators take. As seen here.

The fuel saving sparkplugs work the same way, it's all about compression ratio, and the fact that faster exploding fuel increases compression ratio, and so makes the engine more efficient.

It Enables An Engine To Run Lean Safely And Efficiently


Things to know


Hydrogen, and Browns gas explosion speed is much faster then hydrocarbon fuels

An explosion speed can be lowered by diluting the explosive gas in a larger amount of non explosive gas, like air which is mostly nitrogen.

An engine is like a gear box. On the power stroke when the piston is midway down, the work done per inch of the gas expansion is less. When the piston is near top dead center, or bottom dead center, the work per inch is much higher. This is because the piston only pushes downward, and the elbow joint is farther to the side (greater x-axis value) from the engine shaft.

When an engine is made to run lean, the added air causes the explosion to happen more slowly. A slower burn causes more explosive force to happen at a point where the elbow joint is father to the side of the engine shaft, meaning the explosion does less mechanical work, more of the energy from it stays in the form of heat. Another factor that adds to this is that over the entire power stroke, a larger percentage of the fuel ignites near the bottom of the stroke, disabling the heat to push the piston as far therefore not going into mechanical work, and the energy stays in the form of heat. This is why running lean sometimes causes engines to overheat. Running lean is like running in a lower gear with higher RMP. If the ignition timing is advanced some, then it would work a little better, but overall the problem is that normal fuels don't explode fast enough.

This is where hydrogen generator's come in. Hydrogen's flame front speed it much faster then hydrocarbon based fuels. By leaning the fuel mixture the flame speed is slowed down, then add hydrogen to bring it back to near normal speed. This makes the engine run like normal, but lean.

Why Does Running Lean Improve Efficiency?

Running lean improves the engines thermodynamic efficiency, because with more air around the exploding fuel molecules, more of the heat will go into that air, instead of the combustion chamber walls. When heat goes into the air, it expands, does work by pushing the piston, and cools down some. When heat goes into the combustion chamber walls, it goes into the coolant as wasted energy.

Running lean does not directly hurt the engine, the effect that running lean has retarding the fuel ignition rate, is what hurts the engine. The ignition timing is the same, but the overall ignition of the fuel is slower, so a larger percentage of the fuel ignites when the piston is farther in it's cycle.

What About Ignition Timing?

One of two things, or a combination of them, should be done so the engine will run properly on Browns gas. Either the ignition timing needs to be retarded, or the fuel to air mixture made lean, or a little of both. I suggest leaning the air fuel mixture, and retarding the ignition timing just a little bit. Most computer managed engines will adjust the ignition timing automatically, after the battery is disconnected which resets the computer, and about 10 miles of driving, or as much as 50 miles with the hydrogen generator on. The driving is when the computer relearns the dynamic's of the engine, and makes the adjustments.

How To Make An Engine Run Lean

Computer managed engines have a sensor in the tailpipe called O2 Sensors. These sensors measure the amount of oxygen in the exhaust. If they sense there's too much oxygen in the exhaust the engines computer reduces the amount of air going into the engine. This is what keeps the engine from running lean, to get around this you can purchase an "O2 Extender" as seen here, or one of the other leaning devices seen here.

In summary, with hydrogen injection efficiency can be achieved in two ways.

1. Efficiency by increased compression ratio, and high work load on the combustion, achieved by retarding the ignition timing.

2. Efficiency by running lean, achieved by dulling down the O2 sensor reading.

If only ignition timing is changed, and to a considerable degree, then it may wreck the engine if it runs over 5000 RPM too much.

..what's the right name for that joint on the piston shaft, I called it the "elbow joint" because I don't know what else to call it.

Wrist Pin?  You mean where the connecting rod connects to the piston?

no I mean the bottom of the rod. I was also informed that I miss used the term "compresion ratio," what I mean when I say that is "compression ratio at point of the fuel energy release"
