  • Diagnostic systems for cooling systems for internal combustion engines
    Patent number: 7918129
    Abstract: A control system for an engine system includes a temperature sensor and a diagnostic module. The temperature sensor measures an outlet temperature at an outlet of a cooling system. The diagnostic module estimates the cooling fluid temperature, determines the cooling performance based on the outlet temperature and the cooling fluid temperature, and selectively diagnoses a fault in the cooling system based on the cooling performance and a predetermined threshold.

  • Control system to minimize white smoke using variable nozzle turbo
    Patent number: 7882702
    Abstract: An engine system and method for operating an internal combustion engine includes a turbocharger that generates a boost to the engine. A coolant temperature of the engine is determined along with other based engine inputs and calculated values. A normal boost based on operating conditions of the engine is determined. A supplemental boost is determined based on the coolant temperature. An offset boost based on the normal boost and the supplemental boost is determined. An air output of the turbocharger is modified based on the offset boost. The supplemental boost increases combustion efficiency, which reduces white smoke exhaust.

  • Diesel oxidation catalyst (DOC) temperature sensor rationality diagnostic
    Patent number: 7546761
    Abstract: A temperature sensor rationality control system for an exhaust treatment system having an oxidation catalyst includes an oxidation catalyst inlet temperature sensor that generates an inlet temperature signal and an oxidation catalyst outlet temperature sensor that generates an outlet temperature signal. A control module determines whether a difference based on the inlet temperature signal and the outlet temperature signal is below a difference threshold when an exhaust temperature is within a threshold range.

  • Control system for diesel engine elevated idle and variable nozzle turbo control for stationary vehicles
    Patent number: 7200995
    Abstract: A control system and method for increasing engine temperature for an engine having a variable nozzle turbo (VNT) is provided. An offset idle module generates an offset idle signal. A normal boost module calculates a normal boost. A supplemental boost module calculates a supplemental boost. An offset boost module generates an offset boost signal for the VNT based on the normal boost and the supplemental boost. A control module adjusts engine idle and VNT boost based on the offset idle signal and the offset boost signal.
