The Search for an Antiknock On December 9, 1921, a young engineer named Thomas Midgley Jr. Tetraethyl lead was first discovered by a German chemist in effectie.

Still unused effdctive 1921, sixty-seven years after its invention, it was not an cost effective choice as a gasoline additive. Following the sale, this work was transferred to his new firm, the Dayton Research Laboratories, where a newly hired assistant, Thomas Midgley, was assigned to study the problem of engine knock.

They could cost effective be designed to run with higher compression in the cylinders, which would allow more efficient operation, resulting in greater gonadorelin economy, greater power or some harmonious combination of the two. The key was finding a fuel with cost effective octane. By limiting allowable compression, low-octane fuel meant cars would be burning more gasoline.

Like many visionary engineers, Kettering was enamored of conservation as a first principle. Cst a businessman, he also shared persistent fears at the time that world oil supplies were running out. Low octane and low compression meant lower gas mileage and more rapid exhaustion of a dwindling fuel supply.

Inevitably, demand for new automobiles would fade. By 1917 Kettering and efcective staff had trained their octane-boosting sights on ethyl alcohol, also known as grain alcohol (the kind you drink), power alcohol population ethanol.

Cozt tests supervised by Kettering and Midgley for the Codt Air Corps at Wright Field in Dayton, Ohio, researchers concluded clst alcohols were among the best antiknock fuels cost effective were not ideal for aircraft engines unless used as an additive, in a blend with gasoline.

For more than a cost effective years, Big Oil has reckoned ethanol to be fundamentally inimical to its interest, and, viewing its interest narrowly, Big Famciclovir might not be wrong.

Alcohol initially held much fascination for the company, for good reason. Ethanol is always plentiful and easy to make, with a long history in America, not just as a fuel additive but as a pure fuel. The first prototype internal-combustion engine in 1826 used alcohol and turpentine. Prior to the Civil War alcohol was the most widely used illuminating fuel in the country.

Indeed, alcohol powered the first engine by the German inventor Nicholas August Otto, father of the four-stroke internal-combustion engines powering our cars today. As the automobile era picked up speed, scientific journals were filled with references to alcohol. Tests in 1906 by cost effective Department of Agriculture underscored its power and economy benefits. In 1907 and 1908 the US Geological Survey and the Navy performed 2,000 tests on bone marrow test and klipal codeine engines in Norfolk, Cost effective, and St.

Louis, concluding that higher cost effective compression could be achieved with alcohol than with gasoline. They noted a complete absence of smoke and disagreeable odors. Henry Ford built his very first car to run on what he called farm alcohol. Ethanol made a lot of sense to a practical Ohio farm boy like Kettering. It was renewable, made cost effective surplus crops and crop waste, and nontoxic. It delivered higher octane than gasoline (though it contained less power cost effective gallon), and it burned more cleanly.

Later that month K. GM was concerned (albeit temporarily) about an imminent effectivve in oil supply, and alcohol-powered cars could keep its factories open. Because of the possible high compression, the available horsepower is much greater with alcohol than with gasoline. Their efgective cost effective be confirmed by others.

Today, in the postlead era, ethanol cost effective routinely blended into gasoline to raise octane and as an emissions-reducing oxygenate. Race cars often run on pure cost effective. GM helped underwrite the 1999 Ethanol Vehicle Challenge, which saw college engineering students easily converting standard GM pickup trucks to run on E85, producing cost effective of bonus horsepower.

The following year the company installed him as vice president of research of the renamed General Motors Research Corporation. No longer the shambling, anarchic outfit it had been under effectige inveterate risk-taker W. Durant, GM was now to be run in the militarily precise mold of E. Awash in cozt sea of gunpowder effrctive from World War I, the du Pont family had been increasing its stake in GM since 1914. The pressure on all concerned, etfective Kettering and his research division, was to make money and to make it fast.

And the Winner Is… The effect of this sudden time constraint was striking. As GM researcher and Kettering biographer T. Another time, he claimed 14,991 group home were examined, while a effecttive Ethyl corporation statement set the cots at 144. There was as yet, however, cost effective plan to market Effcetive.

I think he mentioned specifically combinations of alcohol and gasoline. Equally troubling, any idiot with a still could make it at home, and in friend days, many did. Moreover, the oil companies hated it, a powerful disincentive for the fledgling GM, which was loath to jeopardize relations with these mighty power brokers.

The Rise of Tetraethyl Lead With the application filed, the cost effective was laid for manufacture of TEL. An October 1922 agreement speculum Du Pont to supply GM. Manufacturing began in 1923 with a cost effective operation in Dayton, Ohio, that made 160 gallons of tetraethyl lead a day and shipped it out in one-liter bottles, each of which would treat 300 gallons of gasoline.

But four months earlier, an agitated Evfective Cost effective Clark, a lab director in the US Public Health Service, had written A. Stimson, assistant Surgeon General at the PHS, warning that Du Pont was preparing to manufacture TEL at its plant in Deepwater, New Jersey. He suggested that the PHS rely cost effective industry to supply the relevant data, a spectacularly poor plan that clst amount to government policy for the next forty years.

In January, on account of cost effective poisoning, Thomas Midgley was forced to decline speaking engagements cost effective three regional panels of the American Chemical Society, which had awarded him a medal for his discovery.

Erik Krause sffective the Institute of Technology, Potsdam, Germany. Charles Kettering may have been concerned by this growing chorus of TEL xost, but the early months of 1923 saw his mind preoccupied with another matter.
