Abstract

The invention discloses a SCR metering pump offline testing stand which comprises a testing host, a SCR control communication wiring harness, a signal simulation control panel and a to-be-tested metering pump. The testing host is connected with the signal simulation control panel and the to-be-tested metering pump through the SCR control communication wiring harness, controls the signal simulationcontrol panel to collect signals, controls the to-be-tested metering pump to work, monitors state of the metering pump and each part of a PCB thereof at the same time, sends corresponding request functions to the signal simulation control panel and the metering pump to test the corresponding functions and judges whether the metering pump and the PCB thereof are normal or not by analyzing signalsfed back by the signal simulation control panel and the metering pump. The SCR metering pump offline testing stand is low in manufacturing cost and resource consumption, convenient to operate and stable and reliable in testing result and is an essential tool for conducting metering pump researches and good equipment for SCR technology related manufacturers to conduct metering module testing.

Description

technical field [0001] The invention relates to the field of post-treatment of diesel engine exhaust, in particular to an off-line test bench for an SCR metering pump. Background technique [0002] Diesel engines are favored by people for their superior power, economy and emissions, and their application range is becoming wider and wider, and the market share of diesel engines is also increasing. However, as the global environmental problems become increasingly serious, governments of various countries have promulgated relevant laws and regulations to limit the exhaust emissions of automobiles. With the continuous upgrading of regulations, the emission requirements are becoming more and more stringent. Therefore, SCR technology has received more extensive attention. [0003] The SCR (Selective Catalyst Reductio, Selective Catalyst Reduction) system controller is the core component of the diesel engine selective catalytic conversion system that controls the entire system to...
