Abstract: The finger follower has an inner and outer body and a torsional lost motion spring positioned at its lash adjuster end of the outer body. The torsional lost motion spring has two helical parts each with a short leg that abuts the outer body and a long leg that contacts the inner body. The torsional spring is located above the pivot point of the finger follower so as to provide a low mass moment of inertia and to reduce the weight over the valve stem end of the follower.

Abstract: The liquid is sealed in the lash adjuster so that the volume “V1” of the gas, in the reservoir chamber when the lash adjuster is being produced and the plunger protrudes from the body, is equal to or more than 1.24 times as great as the sum of the volume “Vo1” of the liquid discharged from the high-pressure chamber when the plunger moves downward, and the increase “Vo2” in the volume of the liquid that expands, due to heat, when the temperature of the gas in the reservoir chamber is increased from the production temperature to the maximum use temperature, and the ratio of “V1” to “Vo1+Vo2” is equal to or higher than a ratio, which is derived based on the production temperature and the maximum use temperature, when the inner pressure of the lash adjuster increases by 500 kPa at maximum.

Abstract: An oil communication passage (39b) is formed so as to run through a wall portion (39) separating an oil collector (41) and an oil drop hole (38) formed in an engine cylinder head (14), and oil that has collected in the oil collector (41) can therefore be guided to the oil drop hole (38) via the oil communication passage (39b). An oil supply passage (39c) and a retaining hole (39a) for retaining a hydraulic tappet (22), which is operated by oil supplied from the oil supply passage (39c), are formed in the wall portion (39) of the cylinder head (14), and the oil supply passage (39c) and the oil communication passage (39b) communicate with each other via the retaining hole (39a); therefore, even if part of the oil supplied from the oil supply passage (39c) to the hydraulic tappet (22) leaks into the retaining hole (39a), the oil can be discharged by utilizing the oil communication passage (39b).

Abstract: A valve control system includes a vehicle control module that generates a lift mode command signal to transition one of intake and exhaust valves between N open lift modes. A time module generates a response time signal that indicates a duration of the transition and a lift limit signal that disables the transition. The time module generates the response time and lift limit signals based on current lift mode and status signals. The current lift mode signal indicates a current lift state of one of the intake and exhaust valves. The status signal indicates status of a lift control valve. The lift control valve actuates one of the intake valve and the exhaust valve. The event module generates the current lift mode and status signals based on the lift command signal, the response time signal, and the lift limit signal. One of the time and event modules enables the transition.

Abstract: A lash adjuster support portion is integrally formed with a lower cam carrier. The lower cam carrier is fixed onto a cylinder head into which an intake valve and an exhaust valve have been fitted. After a lash adjuster is set in the lash adjuster support portion, a rocker arm is placed on the intake side and a rocker arm is placed on the exhaust side. Camshafts are then placed on the lower cam carrier such that the rocker arm contacts an intake cam and the rocker arm contacts an exhaust cam. An upper cam carrier is then assembled to the lower cam carrier, thus completing the camshaft support structure.

Abstract: There is provided a method for controlling engine valves of an internal combustion engine adapted to selectively operate at one of a first open position and a second open position, including controlling engine operation during a transition from a first to a second combustion mode. The method comprises determining a desired engine airflow based upon an operator torque request. A cylinder intake volume is determined for the desired engine airflow when operating at the first open position. A control scheme is determined to control the engine valves to attain the cylinder intake volume for the desired engine airflow when operating at the second open position. The control scheme is executed and the engine valve is transitioned to the second open position when the cylinder intake volume to operate at the second open position is within a range of authority of the engine valves.

Abstract: A hydraulic reverse spring valve clearance compensation element (RSHVA) for a valve train of an internal combustion engine comprising: a housing (2), which has a blind bore (3), in which a piston (4) is guided with a tight, sealing clearance; the piston (4) comprises a lower piston part (4a) with a lower piston head (5), which together with the blind bore (3) defines a high-pressure chamber (7), whilst a low-pressure chamber (8) is situated above the lower piston head (5); the pressure chambers (7, 8) being connected by a central axial bore (10) in the lower piston head (5), which is controlled by a control valve (11) arranged on the underside (23) of the lower piston head (5); the control valve (11) comprises a control valve ball (19), upon which a control valve spring (20) acts in the opening direction and the lift of which is limited by a lift-limiting stop (24) of a valve ball cap (21), whereby an RSHVA, the idle lift of which is as independent as possible of the viscosity and hence of the temperature of the lubricating oil is to be created and is achieved in that temperature-sensitive means influencing the closing time of the control valve (11) are provided, which lead to a closing time of the control valve (11) that is largely independent of the lubricating oil temperature of the internal combustion engine.
