Gents,

Article in the newspaper today about this company. It dealt in great generalities but was interesting. Web site doesn't shed much more light on subject. Has anyone had anything to do with them?

The aerosol mist is drawn into the combustion chambers using both the vacuum effect from the pump as well as the engines own vacuum.

Show me a diesel engine that creates vacuum and I have a deed to the Newport Bridge that I will give to you.... Snake Oil, plain and simple. RT

RW Thomas and Dude,

Read more carefully. The vacuum pump they are talking about is part of the device and causes the liquid to boil and change to a vapor which is fed into the engine air intake.

A 4 cycle Diesel has some vacuum or the air would not go into the engine. Its not like a gasoline engine where the closed throttle causes a large vacuum but there is a small of vacuum created by a Diesel. I'm talking about the intake stroke, the piston makes a lower pressure inside the cylinder thus the air rushes in. A turbo charger just pushes more air in to the cylinder.

I'm not saying the device works, but I understand how it injects the mist into the engine. I wonder how much the liquid catalyst costs and how far it goes. Somhow it sounds expensive. I didn't see any prices in the web site.

There ain't no vacuum on a turbodiesel. The manifold is almost always operating at positive manifold pressure so how is vacuum gonna pull this stuff in? I suppose they could duct it to the turbo intake pipe but I would hardly call that positive vacuum unless your air filter is dirty..... Moving air doesn't mean there is a vacuum. RT

RW,

The small amount of vacuum in a supercharged or turbocharged Diesel engine is before the input of the turbo or super charger. There is a small amount of vacuum or the air would not rush in.

Remember air is not sucked in by a vacuum, it is pushed in by atmospheric pressure. Any time you have forced air flow, the pressure is lower on the inlet than the output, thus there is a slight vacuum, vacuum defiined as pressure less than atmospheric pressure.

Yes, the stuff could be injected into the air stream before the turbo charger.
