  • Intercooler system for engine air charger
    Patent number: 8191365
    Abstract: An intercooler system and method of operation for use with an air charging system for an internal combustion engine is disclosed. The intercooler system may comprise an intercooler pump for pumping a coolant through the intercooler system, a first heat exchanger that transfers heat from charged intake air to the coolant, a second heat exchanger that transfers heat from the coolant to outside air, and an intercooler coolant reservoir that contains the coolant therein. Coolant lines direct a flow of the coolant through the intercooler pump, the first heat exchanger, the second heat exchanger and the intercooler coolant reservoir.
    Type: Grant

  • Power-hop responsive engine torque control method
    Patent number: 6401853
    Abstract: An improved engine torque control method uses existing powertrain sensors and controls to reliably detect and suppress power-hop with minimum degradation of vehicle acceleration. Power-hop is detected by identifying a characteristic wheel jerk magnitude and oscillation frequency based on driven wheel speeds. Once a power-hop condition is detected, the control method computes a desired engine torque output for suppressing the detected power-hop without unnecessarily degrading vehicle performance, based on the wheel jerk magnitude, the engine speed and vehicle acceleration. A combination of engine cylinder fuel cut-off and spark retard is then scheduled for reducing the engine output torque to the desired level for the duration of the power-hop condition.
