  • Patent number: 10329858
    Abstract: The present invention relates to the field of petroleum extraction equipment, and discloses a coiled tubing unit, which comprises a vehicle body (T), a control cab (30), a coiled tubing reel (10) configured to wind coiled tubing, and a power skid (20) configured to supply power to the coiled tubing reel (10) and transported separately, wherein, the coiled tubing reel (10) and the control cab (30) are mounted on the vehicle body (T). With the coiled tubing unit provided in the present invention, the total length and total weight of the vehicle body on which the coiled tubing reel is mounted are smaller and can meet the requirements for transportation in regions where smaller vehicle dimensions and weight are specified for transportation when coiled tubing in large diameter and/or great length is transported, and the coiled tubing unit is adaptive to the operating habits, and can be deployed flexibly so that it can be used in a well field where the space is limited.

  • Patent number: 9797321
    Abstract: An internal combustion engine includes a cylinder block that defines a cylinder and a cylinder head positioned relative to the cylinder block. A reciprocating piston is arranged inside the cylinder for compressing an air and fuel mixture at a geometric compression ratio of at least 10:1. A crankshaft is arranged in the cylinder block and rotated by the piston. An intake valve is operatively connected to the cylinder head and controls delivery of air to the cylinder for combustion therein. A mechanism provides late intake valve closing via constant peak lift of the intake valve over at least 5 degrees of crankshaft rotation.
