4stSOFT
The original software suite proved very popular, but marketing changes at SAE resulted in its withdrawal from sale and the return of the copyright to its author. Since that time, many textbook purchasers have written to us asking how they may acquire the original software suite. In the interim, the original software suite was not only greatly sophisticated and expanded but was bundled with the 4stHEAD suite and labelled as 4stSOFT. While most 4stHEAD user-clients can freely use 4stSOFT, Prof. Blair & Associates decided to make the 4stSOFT suite available as a stand alone package to satisfy this popular demand.
Areas
included in the program are:
Engine geometry and basic performance characteristics; Otto Cycles with
classic and phased burn; Diesel Cycles with classic and phased burn; unsteady
gas dynamics and thermodynamics of pressure wave propagation, friction
loss and transfer, gas and geometry discontinuities, pipe end wave reflections,
pipe branch wave reflections, cylinder to pipe flow and wave reflections,
and acoustics attenuation at silencers; fully professional programs
for valve lift profile generation, analysis of flowbench data for
discharge coefficients, analysis of cylinder pressure data for combustion
characteristics, empirical design of the cylinder head contents and the
tuning of its attached intake and exhaust ducting to achieve target performance
characteristics (see 4stHEAD
