Due uneven contraction, the cylinder head castings often deform and cause deviation of the ports position.
The use of hydraulic cylinder in hydraulic elevator, the part usually has five parts: piston and piston rod, cylinder and cylinder head, buffer device, sealing device and exhaust device.
Pull oil supply valve on vacuum pump out of the cylinder head using a pair of flat-nosed pliers.
The lifting wavelet package transform based on interpolating subdivision was introduced. The engine cylinder head vibration signal's time-frequency characteristics were analyzed.
Finally, this paper took a production line of 5v engine cylinder head for example, and proposed a process to design prototype system, to improve the efficiency and accuracy of product line p.
Position the cylinder heads onto head gaskets and cylinder block.
If the gasket breaks down, small holes develop between the cylinder and the cylinder head, and these holes cause leaks.
The results show that chaotic and determined features exist together in cylinder head vibration, while the cylinder vibration and block vibration are both purely chaotic.
Tom has machined the second cylinder head flat, and now the block is beginning to take on the "V" shape.
The oxide-coated zirconium of the chambers at the piston and cylinder head, the design of air gap on the auxiliary chamber are applied to lower heat rejection.
The instrument measures vibration signal of diesel cylinder header, extracts the characteristic parameters, to diagnosis for fault of leakage and abnormal space of valve.
Measures to prevent cylinder head nut from loosing has been discovered based on the test and study of the torque of cylinder head nuts for 4125 diesd engine.
The cylinder head water jacket of a high speed diesel engine is analyzed by using CFD technology.
This paper measured the non steady state temperature field of cylinder head in an air cooled engine. It analysed the temperature variation under transient operating conditions of engine.
Remove the engine cylinder head from the cylinder block (refer to cylinder head removal in this section).
Generally, the cylinder and the cylinder head bolt together with a thin gasket pressed between them to ensure a good seal.
Through the analysis to the test results, how to set up a reasonable tightening process for cylinder head bolt is expounded.
The features of cylinder block and cylinder head core assembly vertical casting process are introduced.
The front of the cylinder head is also equipped with oil galleries to supply the intake camshaft VVT.
The assemble process of Conduit and Seat Ring belong to cylinder header will do an important influence on the whole motor power performance.
The effects of water jacket configurations of cylinder head bottom deck on the bridge zone temperature, axial temperature gradient and minor principal stress were investigated.
An engine cylinder head gasket leaking between a cylinder and an adjacent water jacket is indicated by coolant foaming or overheating and loss of coolant.
Remove control cables from cylinder head cover clip.
Valves in modern car engines are located in the cylinder head at the top of the engine.
Dispersed shrinkage is the main reason causing leakage of multi-cylinder heads of diesel engines.
In order to on-line process engine cylinder head vibration signals of mobile equipment, a de-noising method with gradual changing threshold based on lifting wavelet package transform was proposed.
