Problems solved by technology

[0004] In recent years, my country's dual-fuel power technology has also developed rapidly. The gas valve is an important executive component of the dual-fuel engine. The injection volume of the gas valve directly affects the performance of the engine. Before the gas valve is put into use, a large number of experimental tests are required. , at present, there is little research on the measurement and research of gas valve injection volume in China, so there is an urgent need for a gas valve injection volume measurement test bench

Abstract

The invention belongs to the technical field of a gas valve injection quantity measurement testbed. The gas valve injection quantity measurement testbed comprises a gas supply device, a flowmeter anda testbed main body; the gas supply device is configured to provide high-pressure gas; the flowmeter is connected to the gas supply device and configured to measure the injection quantity of a gas valve; the testbed main body is provided with a control module and a constant volume cavity, the control module comprises a control structure and a gas storage chamber, the control module can control opening and closing of the gas valve, the gas storage chamber is connected with the flowmeter, a gas valve mounting site is arranged between the control module and the constant volume cavity, when the gas valve is mounted at the gas valve mounting site, the high-pressure gas passes through the flowmeter and then enters into the gas storage chamber in the control module, the control structure gives anopening signal, the gas valve opens, the high-pressure gas in the gas storage chamber injects into the constant volume cavity through the gas valve. The gas valve injection quantity measurement testbed provided by the invention is simple in structure and can conveniently measure the injection quantity of the gas valve.

Description

technical field [0001] The invention relates to the technical field of measurement test benches, in particular to a gas valve injection quantity measurement test bench. Background technique [0002] As we all know, the transportation industry is one of the industries with high energy consumption, high emissions, and high pollution, and the shipping industry is even more obvious. The emissions of sulfide and nitrogen compounds from ships account for 20% and 30% of the total global emissions respectively. Fuel has become an important factor causing ocean pollution and air pollution. [0003] In order to realize the sustainable development strategy and reduce the further impact of ship exhaust emissions on the ecological environment, the concept of diesel / natural gas dual-fuel powered ships was proposed. The dual-fuel engine uses diesel as the ignition fuel and natural gas as the main fuel. Compared with In terms of oil, liquefied natural gas has the characteristics of abundan...
