Abstract

The invention provides a flame type air inlet heating device test bench. A first throttle valve, a first flowmeter and a first temperature sensor are sequentially arranged on a first pipeline from an air inlet cabin to a component experiment box, and the outlet end of the component experiment box is connected to the air inlet end of an intercooler through a second pipeline; a second temperature sensor and an oxygen concentration tester are sequentially installed on the second pipeline from the component experiment box to the intercooler, the air outlet end of the intercooler is communicated to the exhaust cabin through a third pipeline, a vortex fan is installed on the third pipeline, and an air inlet heating component is installed above the component experiment box. The flame type air inlet heating device test bench provided with the second flow meter capable of measuring the air volume of the small fan and the first flow meter capable of adjusting and measuring the air volume of the vortex fan, the air inlet temperature and the air outlet temperature can be measured, the test bench can meet the functions of plain and plateau test requirements, and a test basis is provided for further optimizing oil and gas matching of a flame type air inlet heating device and further improving the stability and the reliability of a system.

Description

technical field [0001] The invention belongs to the technical field of air intake of diesel engines for vehicles, and in particular relates to a test bench for a flame type intake air heating device. Background technique [0002] The flame-type intake heating device is composed of a heating control module, fan, burner, solenoid valve (or electromagnetic pump) and oil piping system. When working, turn on the preheating switch, and the system will detect the temperature and speed of the water outlet after intercooling to meet the After the heating condition, the glow plug is preheated before being powered on. After the preheating is completed, the driver is prompted to start the engine. When the system detects that the speed is higher than 50r / min, the solenoid valve and fan are powered on, and the combustion air and fuel are misted in the burner. After melting, a combustible mixture is formed, which is ignited by the glow plug to form a flame, and mixed with the low-temperatu...
