Problems solved by technology
[0003] However, the structure of the existing engine is extremely compact, and the outlet pipe of the cylinder head cooling water channel is irregular, which makes the cylinder head cooling water channel complicated, and the distance between the cylinder block and the cylinder head is too small, so that the cooling water cannot flow stably at the inlet of the cylinder head cooling water channel
This makes it very difficult to accurately measure the inlet pressure and outlet pressure of the cylinder head cooling water channel, making it impossible to further accurately calculate the cylinder head flow resistance

Abstract
The invention discloses a flow resistance measuring device of a cylinder cover. The flow resistance measuring device of the cylinder cover comprises a water storage tank, a cylinder cover water inlet pipe assembly, a cylinder cover water outlet pipe assembly, pressure sensors and a recorder, wherein one end of the cylinder cover water inlet pipe assembly is communicated with the water storage tank through a water inlet connecting pipe, a controllable flow water pump is arranged on the water inlet connecting pipe, one end of the cylinder cover water outlet pipe assembly is communicated with the water storage tank through a water outlet connecting pipe, a flow sensor is arranged on the water outlet connecting pipe, the pressure sensors are respectively arranged on each cylinder cover water inlet pipe of the cylinder cover water inlet pipe assembly and each cylinder cover water outlet pipe of the cylinder cover water outlet pipe assembly, and the recorder is respectively connected with output ends of all the pressure sensors. According to the flow resistance measuring device of the cylinder cover, the cylinder cover water inlet pipe assembly and the cylinder cover water outlet pipe assembly which are used for conveniently and accurately measuring a water inlet pressure and a water outlet pressure of a cylinder cover coolant gallery are respectively arranged at a water inlet and a water outlet of the cylinder cover coolant gallery, and thus the water inlet flowing and the water outlet flowing of a cylinder cover are stabilized, and the water inlet pressure and the water outlet pressure of the cylinder cover coolant gallery can be accurately measured.
Description
technical field [0001] The invention relates to the field of engines, in particular to a cylinder head flow resistance measuring device. Background technique [0002] At present, the cylinder head flow resistance refers to the resistance of the coolant of the cylinder head cooling system to flow through the cylinder head cooling channel. In order to accurately calculate the cylinder head flow resistance, it is necessary to accurately measure the inlet pressure and outlet pressure of the cylinder head cooling channel. [0003] However, the structure of the existing engine is extremely compact, and the outlet pipe of the cylinder head cooling water channel is irregular, which makes the cylinder head cooling water channel complicated, and the distance between the cylinder block and the cylinder head is too small, so that the cooling water cannot flow stably at the inlet of the cylinder head cooling water channel . This makes it very difficult to accurately measure the inlet pr...
