Alcohol Fuels Mood: Engine Power and Problems From Gasohol
Kansas State University engineer Mark D. Schrock reports on the performance of ethanol and gasohol in spark ignition engines. Ethanol offers 65 percent energy per volume of gasoline and 83 percent per gallon of propane, with high vaporization energy increasing fuel cost. Phase separation with water limits practical gasohol use at 10 percent alcohol, especially when ethanol quality is below 200 proof. Mixing reduces volumetric heat content, potentially lowering engine efficiency.

Ethanol fueled engines face mixed efficiency and material issues
Schreck outlines how spark ignition engines adapt to gasohol with adjustable jets and closed loop carbs, noting a 2.5 percent mpg drop on 10 percent ethanol blends and potential 3 percent overall efficiency gain at higher compression. He warns of starts below 40F, fuel tank range reductions, and materials compatibility challenges with ethanol replacing gasoline.
Modifying Diesels for Ethanol Use in Agriculture
Kansas State University engineer Mark Schrock discusses four methods to use ethanol in diesel engines. Options include spark ignition conversion, ethanol tolerant engines, mixing ethanol with diesel, and carbureting ethanol into the intake. Results show varied efficiency gains, with ethanol carburetion offering the best potential under high-load conditions.
USDA Offers Insect Control Tips For Farm Stored Grain
A new Farmers Bulletin 2269 from the U S Department of Agriculture provides guidance to protect stored grain from insect damage amid a 1980 risk due to large grain volumes and export delays. The issue notes space pressure from 1979 record crops, 13 million metric tons stored, and possible ground storage increasing infestation risk. 200 000 copies will be distributed via ASCS and State Extension Services. Grain producers applying for or renewing farm-stored grain loans begin signups in March at ASCS offices, with loan holders responsible for grain quality against insects.
