Condensation control for internal combustion engines using EGR

摘要: A system and method for controlling an internal combustion engine to reduce or eliminate formation of EGR condensate monitor current ambient operating conditions determine whether are favorable condensation gases, control the accordingly avoid condensation, preferably by increasing intake manifold temperature. The temperature may be increased redirecting some all flow cooler. Alternatively, in combination, charge air redirected bypass cooler and/or from outlet turbocharger compressor intake, effectively resulting a corresponding increase Conditions determined based on speed load, temperature, pressure, scheduled actual rate air/fuel ratio.
