Engineers at DaimlerChrysler once analyzed valve trains with nothing more than old Fortran programs. But 3D dynamic-simulation software now handles the task with features tailor-made for modeling fast ...

Researchers are designing nano-sized quantum heat engines to explore whether they may be able to outperform classical heat engines in terms of power and efficiency. Researchers from Aalto University ...

Time was when a valve job was done with some valve-grinding compound and a vacuum cup on a stick. But no more. Today's high performance engines require the same machining precision in the valves that ...

This is what you'll see as the output of the Dynomation program. The upper graph illustrates three separate pressure traces plotted against the crankshaft angle. Trace 1 is cylinder pressure, trace 2 ...
