Recently Variable Valve Actuation (VVA) systems are being extensively used in internal combustion engine. In such mechanism, cams and valves are connected via intermediate lever, which allows different maximum valve lifts and duration using same cam profile. Recently, novel valve actuation mechanism like Continuous Variable Valve Lift (CVVL) is being explored to regulate engine output without conventional throttle valve and this reduces the pumping losses especially at part load in SI engines. CVVL mechanism with three elements consists of eccentric shaft, Intermediate lever and Rocker arm, wh

The electrohydraulic valve system can realize continuous variable valve timing and lift using the flexibility of liquid. However, the existing electrohydraulic valve systems usually rely on a high-speed solenoid valve to control the on and off states of the hydraulic circuit, which pushes up the system cost. This paper introduces a continuous hydraulic variable valve timing and lift system with adjustable volume (CVVTL). Unlike the other electrohydraulic valve systems, the CVVTL does not need a high-frequency servo valve to control each valve but adjusts the valve timing and lift by controllin

As to three kinds of continuous gas lift design methods commonly used using surface casing pressure control all have several disadvantages when the pressure drop between the valves is small, and they have some deficiency when gas injection pressure is relatively inadequate on ground or want to play the affection of the gas injection pressure on ground as much as possible, therefore, the applied study is made in this regard. First, the precise calculation method of the top valve depth under different conditions was achieved based on the principle of U type tube, then an improved variable pressu

Variable valve technologies, as an advanced category aimed at enhancing internal combustion engine thermal efficiency and emission performance, are highly favored within the automotive industry. This paper proposes a hydraulic variable valve system that can achieve continuous variation in valve phase and lift while maintaining a simple structure. Pre-tests show that at higher engine speeds, the valve seating characteristics are not stable enough. This study believes that in addition to considering the lower seating velocity, the valve seating characteristics also needs to take into account the

A novel fully hydraulic variable valve system is described in this paper, which achieves continuous variations in maximum valve lift, valve opening duration, and the timing of valve closing. The load of the unthrottled spark ignition engine with fully hydraulic variable valve system is controlled by using an early intake valve closing rather than the conventional throttle valve. The experiments were carried out on BJ486EQ spark ignition engine with fully hydraulic variable valve system. Pumping losses of the throttled and unthrottled spark ignition engines at low-to-medium loads are compared a

A Fully Hydraulic Variable Valve System is described in this article which can achieve continuous variation in valve lift, duration, and timing. The system was installed in a four-cylinder port fuel injection spark ignition engine and achieved unthrottled load control through early intake valve closing. The in-cylinder pressure measured experimentally showed that pumping losses of the unthrottled spark ignition engine at 2000 r/min and 0.189 MPa brake mean effective pressure was reduced by 85.4% compared with the throttled spark ignition engine. However, its slow and unstable combustion reduce

Gearing with a ZK worm and an involute helical gear is used in the motor drive system of automotive continuous variable valve lift (CVVL) because of production cost. Since the geared system does not satisfy the meshing condition, transmission error (TE) and teeth interference (TI) are inevitable. This paper introduces a method for reducing TE and eliminating TI. Transmission error function is derived mathematically and used in checking TI. The first prototype for an automobile shows a lot of NVH problem, which is simply combined by coinciding with the helix/lead angles of two gears at the pitc
