Webb2 juli 2024 · The venting system vents the SCR reactor when the SCR is bypassed (i.e. when the engine is running in Tier-II mode) to avoid exhaust gas accumulation and soot formation in the reactor. The reactor is vented with Fresh Air during Tier II operation. The Reactor Sealing Valve is used to seal the reactor during venting when the SCR is not in use. WebbThe SCR can often replace much slower and larger mechanical switches. The SCR is an extremely fast switch. It is difficult to cycle a mechanical switch several hundred times a minute; yet, some SCRs can be switched 25,000 times a second. It takes just microseconds (millionths of a second) to turn on or off these units.
