  • Patent number: 6244256
    Abstract: An EGR system for an internal combustion engine has a separate, secondary high-temperature cooling loop, in addition to a primary cooling loop. In the secondary cooling loop, coolant flows through a secondary high-temperature exhaust gas cooler, which is located upstream of the primary exhaust gas cooler. A large amount of heat is transferred from the exhaust gases to the coolant in the secondary high-temperature cooling loop. The heat absorbed by the high-temperature coolant is rejected in a secondary high-temperature radiator. Heat absorbed by the primary coolant is rejected in a primary radiator. The two radiators occupy the same amount of frontal area as a single radiator used in a conventional single-stage EGR cooling system, but overall reject more heat to the ambient. In an alternate arrangement, the EGR system for a liquid-cooled internal combustion engine has a single exhaust gas cooler which is cooled by an EGR cooling loop that is independent of the engine cooling system.

  • Patent number: 6244257
    Abstract: An internal combustion engine has electrically controlled hydraulic linkages between engine cams and engine cylinder valves. If it is desired to skip a cam lobe or to modify the response of an engine cylinder valve to a cam lobe, hydraulic fluid is selectively released from the associated hydraulic linkage to permit lost motion between the cam and the engine cylinder valve. Electrically controlled hydraulic fluid valves are used to produce the selective release of hydraulic fluid from the hydraulic linkages. The mode of operation of the engine can be changed (e.g., from positive power mode to compression release engine braking mode or vice versa), or more subtle changes can be made to modify the timing and/or extent of engine cylinder valve openings to optimize engine performance for various engine or vehicle operating conditions (e.g., different engine or vehicle speeds). The valves can be controlled to produce an exhaust gas recirculation event during various operating modes of the engine.
