Simulation And Experimental Studies Of Intake And Exhaust Tuning For Automotive Engine Low-End Torque Enhancement
Modern passenger car engines have been “down-sized” for improved fuel consumption, resulting in high speeds to obtain good performance.

| Summary: | Modern passenger car engines have been “down-sized” for improved fuel
consumption, resulting in high speeds to obtain good performance. Consumers,
however, are demanding improved low-end torque for improved drivability. The
target engine; a 4 valve per cylinder, 1.6L engine with two intake cam profiles and 2
intake runner lengths, was modeled and correlated with measured engine
performance characteristics (power, torque, etc.); and pressure traces from
combustion chamber, intake and exhaust manifolds to establish the confidence level
in the model's prediction.
Enjin kereta penumpang moden telah "dikecilkan saiz" untuk penjimatan
bahan api, maka memerlukan putaran enjin yang tinggi untuk mendapatkan prestasi
yang baik. Pengguna lebih gemar memperoleh tork pada putaran enjin rendah untuk
pemanduan yang lebih baik. Enjin yang dikaji mempunyai 4 injap pada setiap
silinder, 1.6 liter kapasiti, 2 profil sesondol masukan dan 2 ruang masukan yang
berlainan panjang. |
