SUMMARY

The forum discussion centers on the effects of mixing kerosene with gasoline, specifically a 20% kerosene and 80% gasoline blend, on engine performance. Users report that this mixture enhances power output by approximately 20% while increasing fuel consumption by the same percentage. The discussion highlights practical experiments conducted with a lawn mower and a 1999 Chevy Tahoe, demonstrating improved cutting efficiency and acceleration. Additionally, the conversation touches on the chemical properties of the fuels involved, including their densities and combustion characteristics.

PREREQUISITES
  • Understanding of hydrocarbon chemistry, specifically the molecular structures of gasoline (C8H18), ethanol (C2H6O), and kerosene (C12H26).
  • Familiarity with internal combustion engine mechanics and fuel-air mixture principles.
  • Knowledge of fuel density and energy density concepts.
  • Basic understanding of combustion chemistry and stoichiometry.
NEXT STEPS
  • Research the effects of fuel density on combustion efficiency and engine performance.
  • Learn about the combustion characteristics of various hydrocarbon fuels, including kerosene and gasoline.
  • Investigate the legal implications of mixing fuels, particularly regarding tax regulations and safety standards.
  • Explore advanced fuel mixture calculations for optimizing engine performance.
USEFUL FOR

This discussion is beneficial for automotive engineers, fuel chemists, hobbyist mechanics, and anyone interested in optimizing engine performance through fuel mixtures.

Engine air intake valve has 1 moving part. There is no way to keep it lubricated it burns off at 1600 degrees.

Pretty startling that nobody sells kerosene anymore. Did you ever learn the chemistry you needed to help your testing?

I took chemistry in college 45 years ago. If you don't use it you loose it. I have forgotten more than I ever know. I have always wanted to take more chemistry. There could be some education chemistry on YouTube I need to look. It would be fun to take chemistry again but I will feel weird in a chemistry class with people 20 years old and me being older than the professor. I bet first question the professor asks me is, WHY are you here? LOL

Just as well. You wouldn’t learn how to address the kinds of questions you were asking in college chemistry. You would need to take an automotive engineering class to answer those kinds of questions.
