摘要: An adaptive cruise control system that provides a smooth following by limiting the headway to keep it lower than a predetermined maximum. The present invention accomplishes this objective through systematically limiting the headway. In particular, the present invention reduces a time related speed multiplier used in calculating the desired headway, to maintain a headway that is less than an effective maximum sensor range for the adaptive cruise control system.

摘要: An improved individual cylinder fuel control method based on sampled readings of a single oxygen sensor responsive to the combined exhaust gas flow of several engine cylinders. A model-based observer is used to reproduce the imbalances of the different cylinders and a proportional-plus-integral controller is used for their elimination. Both the observer and the controller are formulated in terms of a periodic system. The observer input signal is preprocessed such that it reflects at each point of time the deviation from the current A/F-ratio mean value calculated over two engine cycles. Therefore, transient engine operating conditions do not harm the reconstruction of the cylinder imbalances dramatically. The control algorithm features process/controller synchronization based on table lookup and a mechanism to automatically adjust the mapping between the observer estimates and the corresponding cylinders if unstable control operation is detected.

摘要: An improved engine control in which the fuel volatility is detected based on a measure of the fired-to-motored cylinder pressure ratio, and used to trim fuel and spark timing controls during engine warm-up and transient fueling periods. In a first embodiment, a matrix of empirically determined pressure ratio values that occur with fuels of differing volatility is stored and compared to the measured pressure ratio to identify the closest stored pressure ratio, and the fuel volatility is determined based on the fuel volatility associated with the identified pressure ratio. In a second embodiment, the actual fuel vapor-to-air equivalence ratio is computed based on the measured pressure ratio, and the fuel volatility is determined based on the deviation between the actual ratio and the desired fuel vapor-to-air equivalence ratio.

摘要: A continuously variable transmission (CVT) has a drive sheave (30) and a driven sheave (36), each of which has an adjustable portion (32,38), that is positioned by hydraulic control piston (28,34). The pistons (28,34) are pressurized from a control system to properly position each adjustable portion (32,38), such that a flexible drive member (40), trained over the sheaves (30,36), operates at the required diameter to establish the desired speed ratio between the drive sheave (30) and the driven sheave (36). The control has two variable displacement pump assemblies (10,26) that supply hydraulic fluid at the required pressure to maintain the desired ratio and to effect a ratio change as required by the operating conditions. One of the pumps (10) supplies a primary pressure which is proportional to the torque requirement of the CVT and the other pump (26) supplies the necessary pressure bias to effect the ratio change. The ratio control pump (26) is variable to both sides of a neutral condition such that the ratio control fluid can be delivered to either adjustable portion (32,38) while the primary pump (10) maintains the required torque capacity pressure in the system.

摘要: An exhaust driven turbocharger (10) for a medium speed diesel engine such as for use in a diesel locomotive includes an exhaust duct (26) supported at one end by a rotor support (14) having rigidly connected feet (42) mountable upon a rigid base. The exhaust duct (26) is supported at an axially opposite end by an exhaust duct support (36) that includes laterally spaced support legs (44) extending from individual mounting feet (46) to points (48) connecting with a support portion (50) of the exhaust duct support (36) located above the axis of the rotor. The legs (44) are configured to be essentially rigid in reducing vertical forces, but are made flexible laterally and axially so as to allow both lateral and radial expansion and contraction of the exhaust duct while limiting resulting stresses from the thermal variations in the exhaust duct (26), the exhaust duct support (36) and the supporting base.

摘要: A turbocharger rotor (12) includes a turbine wheel (18), a compressor wheel (20), a shaft (52) extending between the turbine and the compressor wheels for rotation together about an axis, and connecting means including two pairs of non-locking cones. In a preferred embodiment, the cones include external cones (66,70) on the turbine and compressor wheels and internal cones (68,72) on the ends of the shaft (52). The non-locking cones are centered on the axis with the external and internal cones drivingly engaging one another to align and connect the wheels with the shaft. A long bolt fastener (78) extends through the compressor wheel and the shaft to engage the turbine wheel and hold the rotor components in assembly. An alternative embodiment includes engaging radial surfaces (106,122) outward of the cones. The radial surfaces share the transmission of torque through the connecting means and assist in stabilizing the joints between the shaft and the connected wheels.

摘要: A hydraulic mount (10, 110) for automotive engine and powertrain applications includes an elastomer body (12, 112), a base (30, 130) and a partition (24, 124) interposed the body and the base to form a fluid-pumping chamber (22, 122) and a reservoir (37, 137). Circumferentially spaced axial extending holes (52) or slots (53) or an annular orifice track (151) are formed in the partition together with a magnetic coil (54, 154) operable to impose a magnetic field on the holes, slots or orifice track to control the shear properties of a magnetorheological (MR) fluid in the pumping chamber and reservoir. An elastomeric decoupler member (46, 146) is in communication with at least one of the pumping chamber and the reservoir to reduce the mount dynamic stiffness for isolating low-displacement relatively high-frequency vibrations. Vibrations of multiple frequencies may be isolated by tuning the mount with a controller (58, 158).

摘要: An improved turbocharger for railway locomotive sized engines includes, in a preferred embodiment, first and second axially spaced ball bearings supporting a rotor with the first bearing being a hybrid ceramic ball bearing mounted to accept both radial and axial loads acting on the shaft at the compressor end. The first bearing is mounted on a reduced diameter portion of the shaft, providing reduced bearing diameter to acceptably limit centrifugal loading of ceramic balls in the bearing against a surrounding bearing race. The first bearing has dual rows of ceramic ball bearings mounted to share all axial thrust loads on the shaft. The second bearing is also a ball bearing. Lubrication of the bearings is preferably by direct impingement on the inner race to minimize oil churning causing heating and power loss. Additional features and advantages are disclosed.

摘要: A gas dynamic machine, such as a turbocharger (10), compressor or turbine, includes a housing (13) and a rotor (12) mounted in the housing (13) and rotatable on an axis (16). A bearing (48) and seal (76) member or assembly (90) includes a bearing mounted in an axial bore of the housing and having an inner bearing surface radially supporting a bearing journal of the rotor (12) An axial oil seal (76) is aligned with and fixed to the bearing (48) for radially positioning the seal (76) in axial alignment with the journal bearing (48) surface of the bearing/seal assembly (90). The seal (76) may further include a generally radial flange (78) fixed to the housing (13) for axially positioning the bearing/seal assembly (90) relative to the rotor. The bearing (48) and seal (76) may have separate bodies attached together or be combined in an integral body. Mounting with a single radial pilot for radial location and a single radial flange for axial location, which may be combined, is featured. An optional thrust flange may be integral with the bearing portion or attached as a separate body.
