ABSTRACT In low-temperature combustion concepts such as partially premixed combustion, the ignition delay should be large enough in order to ensure sufficient fuel and air mixing before the start of ...

SAE International Journal of Engines, Vol. 14, No. 3 (2021), pp. 335-344 (10 pages) The addition of a spark plug in place of the original fuel injector and fumigating natural gas (NG) inside the ...

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 ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

In response to stricter global emissions standards, automakers are looking for new ways to wring every last bit of efficiency out of the internal-combustion engine. In this Engineering Explained video ...

YouTuber Integzaa’s latest video gives us a neat look inside the combustion chamber of a four-stroke engine, using a transparent cylinder to show us how the piston moves within it to create internal ...

Homogeneous charge compression ignition (HCCI) engines combine a diesel's torque and fuel efficiency with a gas engine's cleaner emissions. The HCCI technique has been a goal of automakers since the ...

Engine cylinders can misfire due to problems with the ignition system, the fuel system, air and compression, or sensors and ...

With stricter emission standards and the rise of electric powertrains, it might seem like the internal-combustion engine's days are numbered. But Engineering Explained host Jason Fenske believes ...

With all the recent emphasis on electric vehicles, we often overlook the technology that still powers most cars on the road today. The internal combustion engine (ICE) has been at the heart of the ...
