Motor fuels gasohol

Gasohol - [ALCOHOL FUELS] (Vol 1) - [CHEMURGY] (Vol 5) - [GASOLINE AND OTHER MOTOR FUELS] (Vol 12) - [cross-reference entry] (Vol 12) -as synthetic liquid fuel [FUELS, SYNTHETIC - LIQUID FUELS] (Vol 12)... 

A few other comments Ethanol is listed by OSHA as a suspect but unproved carcinogen, but OSHA does not have jurisdiction over beverage alcohol, nor, since it is a natural product, does the Delaney Amendment apply. This could lead to paradoxical situations. Ethanol will continue to grow explosively in volume in the next few years as a motor fuel indeed, this has happened in Brazil. The field is extremely volatile, and new developments occur every week, particularly with respect to fermentation and gasohol. Things should be clearer in about five years, and we should remind ourselves to take a similar look at ethanol then. 

Like methanol, ethanol is a good motor fuel, with similar advantages and disadvantages. The race cars at the Indianapolis 500 have used ethanol as their primary fuel since 2006. A car s carburetor must be adjusted (for a richer mixture) and fitted with alcohol-resistant seals if it is to run on pure ethanol. Solutions of about 10% ethanol in gasoline ( gasohol ) work well without any adjustments, however. 

A considerable wood hydrolysis industry with rather old traditions is located in the Soviet Union. The main fermentation product based on hexoses in wood hydrolyzates is ethyl alcohol, but pentoses and aliphatic acids can also be utilized in the production of proteins (see Section 10.2.3). A variety of chemicals, including ethylene, ethylene oxide, acetaldehyde, and acetic acid, can be produced from ethyl alcohol. One interesting future application of ethyl alcohol concerns its use as a motor fuel mixed with gasoline (gasohol). 

Car engines can burn pure alcohol or gasohol, an alcohol-gasoline mixture (10% ethanol in gasoline), with little modification. Gasohol is now widely available in the United States. The use of pure alcohol as a motor fuel is not feasible in most of the United States because it does not vaporize easily when temperatures are low. However, pure ethanol could be a very practical fuel in warm climates. For example, in Brazil large quantities of ethanol fuel are produced for cars. 

Source Detected in distilled water-soluble fractions of 87 octane gasoline (24.0 mg/L), 94 octane gasoline (80.7 mg/L), Gasohol (32.3 mg/L), No. 2 fuel oil (0.50 mg/L), jet fuel A (0.23 mg/L), diesel fuel (0.28 mg/L), militaryjet fuel JP-4 (17.6 mg/L) (Potter, 1996), new motor oil (0.37-0.40 jg/L), and used motor oil (195-198 Jg/L) (Chen et ah, 1994). Diesel fuel obtained from a service station in Schlieren, Switzerland contained benzene at a concentration of 76 mg/L (Schluep et al, 2001). The average volume percent and estimated mole fraction in American Petroleum Institute PS-6 gasoline were 2.082 and 0.2969, respectively (Poulsen et al, 1992). Schauer et al. (1999) reported benzene in a diesel-powered medium-duty truck exhaust at an emission rate of 2,740 pg/km. 

One possible solution is to increase the use of ethanol as an oxygen additive to gasoline. Some experts had long recommended a gasoline-alcohol mixture known as gasohol as an inexpensive, efficient fuel for use in motor vehicles that would reduce the emission of carbon... 

Gasohol a term for motor vehicle fuel comprising between 80-90% unleaded gasoline and 10-20% ethanol (see also Ethyl alcohol). 

Many different opinions have been expressed as to whether gasbhol is a feasible fuel for motor vehicles. An important economic question is Does 10% grain-based-alcohol-ingasoline gasohol produce positive net energy Examine the details of the energy inputs... 

Despite present predictions for the number of diesel-powered cars in Europe to increase markedly, discussions on the engineering approach to the control of automobiel emissions have centered on the gasoline motor. Cylinder wall temperature, air-fuel ratios, exhaust gas catalysts, and lead traps were presented and discussed as remedies. Blended fuel, for instance gasohol or synthetic fuels, were not considered because they are used on a local basis or during transient, difficult conditions. The contribution of lubricating oil in PAH emissions exists but was not considered an important issue, and was not discussed in the meeting.
