Jet engines are at the heart of modern air travel, powering the majority of commercial aircraft. These advanced propulsion ...

Read about the indirect and direct injection, fuel economy and combustion aspects of how a diesel engine works, only on dieselpowermag.com, the official website of Diesel Power Magazine.

At low throttle, when the engine is loafing and combustion chamber temperatures are relatively low, the tip behaves like a hot plug because of its inherent design. (See Figure 3.) ...

Like any internal combustion engine, your Honda gets hot. Really hot. You might not be surprised to hear that its exhaust gas temperatures reach upwards of 1,500 degrees F, but did you know that ...

Exhaust gas temperature does not provide an accurate measurement but gives a good indication of heat in the cylinder during combustion, and is most commonly measured close to the head.

If that weren't enough, the part of the spark plug projecting into the combustion chamber is exposed to the high-temperature chemical processes inside a cylinder bore. See All 13 Photos ...

Nitrogen oxides are formed in an engine when diesel fuel burns in the air of the combustion chamber. Air consists of 21 percent oxygen and 78 percent nitrogen. Diesel fuel reacts with oxygen ...

Direct injection to the rescue. When a conventional fuel injection systems squirt atomized fuel into the combustion chamber, it does so at a pressure of about 120 pounds psi (per square inch ...

As your accelerator is depressed, your engine’s throttle plate opens and allows air into the engine. When you release your accelerator, the throttle plate closes and prevents airflow from reaching the ...
