Most aspects of a cylinder head are relatively straightforward and easily grasped. Valve size, deck thickness and combustion chamber volume are often topics of discussion and qualify the design's ...

In a sea of LS swaps, the name "hemi" carries a lot of emotional baggage for those retro-minded enthusiasts among us. If you've got a hemi, your chest might well puff up with pride, and if you don't, ...

Today we're looking at how the regenerative cooling channels on Space Shuttle's main combustion chamber were manufactured. They used a combination of conventional machining with electroplating, in a ...

A better mousetrap? Even now, as electrification seems poised to end the internal combustion engine’s long run as the transportation motivator of choice, enterprising tinkerers continue to propose ...

HOT ROD’s archives are chock-full of brilliant tech reports that truly are timeless. This one, drafted by Jim McFarland for our February 1972 issue, provides an extensive look at how important airflow ...

Inlet unstart is a particularly critical issue associated with scramjets. That is the upstream displacement or disgorging of the original inlet shock system. Large flow spillage can be caused by the ...

The Combustion Dynamics group deals with combustion dynamics processes in rocket combustion chambers. This includes the experimental investigation of propellant injection into the combustion chamber, ...

Say 'Hemi' and the first company that will undoubtedly enter most enthusiasts' minds is 'Chrysler'. That won't surprise many, given that the American manufacturer has built a substantial brand around ...

This combustion concept is characterised by the injection of air-fuel mixtures into the combustion chamber in the form of jets with high flow velocities. The arrangement of the jets results in a ...
