There are plenty of articles on combustion testing, equipment adjustments, and efficiency, but few on basic combustion knowledge or understanding. To some people, promoting setting gas pressure, ...

Despite sounding like a thoroughly entertaining evening out, it is actually a description for one of the most important processes in the majority of engines. Known as the four-cycle, it is the process ...

In the 6th grade unit on the "Mechanism of Combustion," the focus is on thinking about the mechanism based on changes in air before and after combustion. Gas jars, candles, gas detector tubes, ...

You've seen the evidence. You disassemble an engine and witness the appearance of deposits—or their absence—on piston crowns and combustion chambers in the cylinder heads. You can relate the presence, ...

The danger of the ever-increasing levels of carbon dioxide (CO2) in Earth's atmosphere has become one of the most pressing issues of our age. As such, much research has been conducted to find ways not ...

Air and fuel are drawn into the cylinder and compressed into the combustion chamber by the rising piston. Just before TDC a spark at the spark plug ignites the mixture which burns rapidly across the ...

James Kelly didn't grow up knowing he wanted to be a writer, but once he fell into the whacky world of automotive journalism, he hasn't wanted to leave. In college, he found ways to make every paper ...

A billionth of a second: That's how quickly some of the most critical chemical reactions of combustion occur. Argonne chemist Stephen Pratt leads the Gas-Phase Chemical Dynamics Group at Argonne. His ...

Researchers at the Department of Energy’s Lawrence Berkeley National Lab (Berkeley Lab) and the University of Hawaii have uncovered the first step in the process that transforms gas-phase molecules ...

Under the necessary conditions of ignition and proper burn rates (cylinder pressure history), both these conditions can exist in virtually any engine. But, in particular, they certainly apply to race ...
