Abstract: In this study, bench tests of a heavy-duty turbocharged natural gas spark ignition engine were conducted with intake air injection at full load and different engine speeds. The flow characteristic of the compressor was ...

Abstract: The major objective of this work is to investigate the synergistic lubricating performance of hexagonal boron nitride (h-BN) and graphite fluoride (GF) nanoparticles (NPs) in white oil. The tribological tests were carried ...

Abstract: With the application of various high-power electronic devices to improving aircraft comprehensive performance, there has been a significant interest in the use of high heat flux dissipation technology to maintain an effective ...

Abstract: Interface interaction between gallium-based liquid metal and copper-based materials results in the formation of intermetallic CuGa2 grains. In particular, CuGa2 grains are able to produce a uniform film and the newly formed ...

Abstract: The accuracy of industrial robots is the most serious problem in industrial manufacturing and production. Kinematic calibration can effectively improve the pose accuracy of the robot's end effector. The effect of kinematic ...

Abstract: 7xxx-Series aluminum alloys have a wide application prospect in the automotive industry due to its higher strength than other series of aluminum alloy. However, little literature has been reported on the formability and ...

Abstract: The western Pacific subtropical high (WPSH) is regarded as the key circulation system that dominates the summer heat waves over eastern China, but whether the WPSH?summer heat wave connection changes with time remains ...

Abstract: Artificial joint materials often wear out due to poor lubrication, affecting their service life. A compound texture (com-texture) was prepared, to improve the spreading of lubricant at the friction interface and reduce the ...

Abstract: After total joint replacement surgery, frequent injection of lubricating substances is required due to lubrication failure caused by the absorption of lubricants by the human body, which will cause serious physiological ...

Abstract: Vehicle steering comfort is an important issue for steering control of advanced driver assistance systems (ADAS), especially the shared steering control systems. However, it is difficult to be evaluated objectively, that ...
