摘要： A self-contained lash adjuster includes a closed end cylinder body and a plunger in the cylinder defining a pressure chamber at the closed end of the cylinder and an internal reservoir connected with the chamber by a one-way passage in the plunger. A diaphragm sealing the reservoir is loaded by a spring piston to pressurize the reservoir and apply a differential pressure extending force to the plunger. The plunger is preferably made in two parts with the diaphragm in the lower part defining the chamber and the piston in the upper part distal from the chamber. The two-part construction permits leakdown testing before permanent installation of the diaphragm. A seal in the lower part beyond a return port seals the plunger walls to the cylinder. Installation during assembly of excess fluid for make-up is controlled by positioning of the plunger lower part during filling in a hyper extended position beyond the fully extended position to which the plunger is limited after full assembly of the lash adjuster.

摘要： A variable cam phaser has drive and driven members connected by helical splines of an annular phase control piston and a lash control piston, axial motion of which varies the angular phase relation between the drive and driven members. A single wave spring received in a groove in one of the pistons biases them apart to take up lash in the splines. A return spring biases the phase control piston to an initial phase setting. Pre-timing of the members is provided for by a driven (or drive) member comprising two components, a hub flange that supports the other member and a splined hub carried by and initially rotatable on a tubular protrusion of the hub flange. After assembly of the phasing mechanism, the hub is rotated on the hub flange to pre-time the initial phasing of the members. An end of the tubular protrusion is then deformed into a flange engaging an annular shoulder on the hub to lock the hub and hub flange members together and maintain the pre-timing. An annular cover is then installed and retained by a retaining ring to close a hydraulic pressure chamber and help support the members. Upon assembly to a camshaft, a center bolt clamps the cover, hub and hub flange to the camshaft and relieves the locking means from operational torque loads.

摘要： Improved systems and methods for dosing agent injection adaptation for a selective catalytic reduction (SCR) system of an engine of a vehicle involve an adaptation procedure that is generally divided into distinct phases based upon the requirement to obtain an accurate dosing adaptation. The phases themselves provide the specific functions of catalyst ammonia storage depletion, catalyst ammonia storage and NOx conversion stabilization, and adaptation value factor determination and verification.

摘要： A variety of methods and arrangements for operating an internal combustion engine and one or more motor/generators in a hybrid vehicle are described. In various embodiments, the engine is operated in a skip fire mode. Depending on the state of charge of an energy storage device and/or other factors, the engine is operated to generate more or less than a desired level of torque. The one or more motor/generators are used to add or subtract torque so that the motor/generator(s) and the engine collectively deliver the desired level of torque. In some embodiments, the engine may be run with a substantially open throttle to reduce pumping losses and improve fuel efficiency.

摘要： An improved SCR system for controlling NOx levels in internal combustion engine exhaust, comprising a least one ammonia sensor disposed at an intermediate longitudinal location in an SCR catalyst and in communication with a System Control Module (SCM). The ammonia measurement permits calculation of ammonia storage on catalyst sites via a stored SCM algorithm. Locating the ammonia sensor midway in the catalyst allows for optimum control of NOx reduction and permits the portion of the catalyst downstream of the sensor to be treated as a slip catalyst, thus minimizing or eliminating the need for a second slip catalyst and housing, and reducing the size, volume, complexity, and cost of an SCR system. In-brick ammonia sensor permits the system to manage engine exhaust to a desired NOx conversion level and ammonia slip target value, thus minimizing the rate of consumption of ammonia while meeting required limits for NOx emissions.
摘要翻译：一种用于控制内燃机排气中的NOx水平的改进的SCR系统，包括设置在SCR催化剂中的中间纵向位置并与系统控制模块（SCM）通信的至少一个氨传感器。氨测量允许通过存储的SCM算法计算催化剂位点上的氨储存。在催化剂中途定位氨传感器可以最大程度地控制NOx还原，并允许将传感器下游的催化剂部分作为滑动催化剂进行处理，从而最大限度地减少或消除了对第二滑移催化剂和壳体的需求，并减少 SCR系统的尺寸，体积，复杂性和成本。砖内氨传感器允许系统将发动机排气管理到所需的NOx转化水平和氨滑移目标值，从而使氨的消耗速率最小化，同时满足NOx排放的要求限制。

摘要： A camshaft has, for each valve lifter, a high lift cam between two low lift cams, the high lift cam fitting within the envelope of the low lift cams. The lifter comprises an outer tappet elongated in the direction of the camshaft and slidably mounted in an elongated bore in a cam carrier. The outer tappet is contacted by both low lift cams and operates two valves simultaneously. An elongated bore extending transverse of the outer tappet carries an elongated inner tappet which is contacted by the high lift cam. A hydraulically actuated locking mechanism couples the tappets for movement together for high lift operation and unlocks for low lift operation to allow the inner tappet to idle in the outer tappet.

摘要： A phase adjuster for engine camshafts and the like includes in a preferred embodiment a sprocket driving a camshaft attached hub through paired wedge packs that transfer torque and maintain a lash free connection. A plunger actuated by engine oil pressure and coating drive springs axially move alternate active wedges to oppositely vary the arcuate lengths of the wedge packs and thereby change the phase angle between the sprocket and camshaft. A three way valve shuts off pressure oil flow except when needed to advance the plunger, thus minimizing oil flow requirements.
