This is Regeneration. The regeneration of the muffler filter consists of own regeneration and mandatory regeneration. The mandatory regeneration consists of auto regeneration and manual regeneration. (Refer to SYSTEM \/ Control System.)\u003cbr\u003eOwn Regeneration\u003cbr\u003e1. The own regeneration regenerates by using the high-temperature-exhaust gas without the diesel oxidation catalyst (DOC) (6) function.\u003cbr\u003e2. A catalyst is activated in case the exhaust temperature of the inlet of filter (5) is higher. Then, regeneration amount increases.\u003cbr\u003e– Mandatory Regeneration\u003cbr\u003e1. Fuel is injected (post injection (11)) to exhaust gas which burns in engine cylinder (7) and exhaust gas mixed with unburnt fuel is supplied to diesel oxidation catalyst (6).\u003cbr\u003e2. Diesel oxidation catalyst (6) oxidizes unburnt fuel and raises exhaust temperature.\u003cbr\u003e3. Therefore, exhaust temperature of the inlet of filter (5) raises up to about 580 to 600 C and regeneration is carried out.\u003cbr\u003eNOTE: When exhaust temperature before filter (5) is 250 C or more, post injection (11) is carried out. When exhaust temperature before filter (5) is 250 C or less, multi-injection (10) is carried out and raises exhaust temperature. Multi-injection (10) is carried out when coolant temperature is 70 C or more.\u003cbr\u003eAuto Regeneration:\u003cbr\u003e– The mandatory regeneration is automatically carried out in 8 hours after the last regeneration. (Time Regeneration)\u003cbr\u003e– The mandatory regeneration is automatically carried out when the output from differential pressure sensor (4) is beyond the fixed value before 8 hours after the last regeneration.\u003cbr\u003e(Differential Pressure Regeneration)\u003cbr\u003eManual Regeneration:\u003cbr\u003e– When Muffler Filter Regeneration Request is displayed on the monitor, the regeneration is manually carried out by not operating the accelerator pedal (setting the engine speed at slow idle speed), activating control lever lock switch, setting the forward\/reverse lever to the neutral position, applying the parking brake, and setting the muffler filter regeneration switch to the regeneration position.","brand":"Uploader","offers":[{"title":"Default Title","offer_id":53593328353611,"sku":null,"price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/2519\/4315\/files\/1-128_04b3a6f5-d751-4548-838e-a75ce94eb856.png?v=1760374871","url":"https:\/\/manualbull.com\/products\/hitachi-zw250-5b-wheel-loader-service-repair-manual-workshop-guide","provider":"ManualBull","version":"1.0","type":"link"}
