Abstract
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.
