Abstract

See full text

A system for estimation of exhaust gas temperature for internal combustion engine at low operating temperatures allows determination of when use of exhaust gas temperature sensor measurements is allowable for engine diagnostic. One approach implements a physical model of pressure and temperature drops across a dual stage waste-gated turbo-charger along with modifiers based on current operating conditions to estimate the temperature in the exhaust manifold. Another models combustion to estimate the temperature in the exhaust manifold.
