FEEDING A DYING HORSE

Ethyl Corporation has done more than winning a court victory over EPA. Its engineers have developed a manifold for car engines which is simple to mass produce and has no moving parts, yet achieves the EPA emission standards without either catalysts or unleaded gasoline, that is, without EPA's method of producing sulfuric acid.

The most elementary method of pollution control is to burn less fuel. Even a horse will produce less horse manure if you feed it less food. The trouble is that the horse will die at the very moment when it has finally learned to eat nothing at all.

In automotive terms, one feeds the cylinders a gas-air mixture that is as lean as possible - just rich enough to ignite. But that is easier said than done. A carburetor is already quite complicated by the devices to keep the mixture adequate for warmup, idling. and different speeds and loads. On top of that, it has to supply several cylinders, and up to now, it simply fed just enough to prevent the weakest horse (cylinder) from dying; the others are feasting on too much hay.

Ethyl's Turbulen Flow System keeps all the horses equally undernourished while getting the maximum work out of them. In essence, this is achieved by a manifold that uses the exhaust heat and a conditioning chamber to homogenize the mixture before it goes to the cylinders. Actually, there is a little more to it, for an engine with the TFS system will run on a mixture even leaner than the weakest horse used to get.
