    Abstract: A system including a target module determining a target temperature of coolant at an input of an engine for a maximum amount of fuel efficiency. A mode module disables closed loop control based on temperatures of coolant entering the engine and at an output of a radiator. An open loop module determines first and second temperatures of coolant at inputs of a coolant control valve that receive coolant from the radiator and a channel that bypasses the radiator. A ratio module determines a ratio based on the first and second temperatures and the temperatures of the coolant entering the engine and at the radiator output. A closed loop module generates a correction value based on the target temperature and the temperature of the coolant entering the engine. A position module adjusts the coolant control valve based on the ratio, the correction value and whether closed loop control is disabled.

    Abstract: A method is disclosed for improving fuel economy in an internal combustion engine. The method may involve sensing a temperature of an engine block and determining a block thermal energy representing an ability of the block to reject heat. An open loop control scheme may be used together with the block thermal energy to predict if a coolant in the block is about to enter a boiling condition and, when this is about to occur, to open a block valve to permit a flow of coolant through the block. A closed loop control scheme may be used together with the sensed temperature of the block to determine if a coolant boiling condition is about to occur, and to control the block valve to permit a flow of coolant through the block which is just sufficient to prevent the onset of coolant boiling in the block.

    Abstract: A palladium-only (i.e., platinum free) oxidation catalyst body is used to oxidize carbon monoxide and hydrocarbons in the exhaust stream of a diesel engine powered vehicle, which is operated at a fuel-lean air-to-fuel ratio (A/F) for much of the time it powers a vehicle. Periodically, a recent history of the temperatures of the exhaust gas at the inlet to the palladium oxidation catalyst body is prepared in a computer control module. And a recent history of the A/F of the operating engine is considered. These temperature and A/F values are then used in determining whether the engine should be temporarily operated in a fuel-rich or stoichiometric A/F mode to provide an exhaust gas composition suitable for rejuvenation of the palladium by reducing its oxide formed during lean operation of the engine.

    Abstract: A waste heat recovery system with an integrated hydrocarbon adsorber for a vehicle having an internal combustion engine that generates exhaust gas containing hydrocarbons, and a catalytic converter, includes an exhaust gas conduit, an exhaust gas heat exchanger, a heat exchanger bypass valve, a coolant circuit with a coolant bypass and a coolant bypass valve, and a controller. The exhaust gas heat exchanger includes at least one channel through which the exhaust gas is flowable, the channel having an interior surface coated with a hydrocarbon adsorbing material configured to adsorb hydrocarbons. The heat exchanger and coolant bypass valves are configured to selectively direct at least a portion of the exhaust gas and the coolant, respectively, to the exhaust gas heat exchanger or to bypass it. They are controlled by the controller such that the hydrocarbons in the exhaust gas are selectively adsorbable by and desorbable from the coating.
