The position and size of the monochromator, focusing curvature radii and tilting angles of the germanium focusing monochromator under different different take-off angle, size and divergency of the second collimator and intensity loss due to the use of it were determined. The neutron flux at different wavelength, under different reflection and take-off angle of the monochromator and divergency of the first collimator, were given. The simulation on the aperture used for limiting beam size in front of the sample showed that, smaller the size of the aperture and further the distance from the aperture to the sample, greater the loss of the intensity and more serious the spread of the beam along vertical direction at the sample position which makes the practical sampling volume greater than expected.

A great number of dynamometer experiments are carried out to investigate the effects of structure characteristics of the injector, configuration of combustion chamber, design of the bypass valve and fuel injection phasing on the performance, emission, fuel consumption of the engine during light load operating conditions. After a final optimization and other practical considerations, the control MAPs for the two-stroke DISI prototype engine are obtained. The torque performance, fuel consumption and emission economy of the engine is tested and compared with those of the original carbureted engine.

When the flow through the balance of the piston damping the flow of holes increases, the balance of the piston, the next increase in pressure on both sides of a balanced increase in the distance the piston increases, and vice versa reduced; and also because the spring stiffness is very small, so that shift the balance of the piston pressure required very few changes, so the flow through the Poppet head is not much change, so the first opening Poppet very few changes, to mention the pressure of moving the first opening can be said to remain unchanged, that is, when the pilot valve spring after a set, Poppet Head was opened, the balance piston chamber pressure remained basically unchanged.
当流经平衡活塞上阻尼孔的流量增加时,平衡活塞上、下两侧的压差增加,平衡活塞上升距离增加,反之则减小;又因为弹簧的刚度很小,使平衡活塞上移所需压差变化很小,所以通过提动头的流量变化也不大,因此提动头的开口变化很小,提动头开启的压力可以说是不变的,亦即当先导阀的弹簧一经设定后,提动头被打开时的平衡活塞上腔的压力基本保持不变。
