Jun 15, 2015 · SCR stands for Selective Catalytic Reduction, this is an active emissions control technology system used in diesel engines. Basically SCR controls the amount of emission given off by your truck, where a liquid-reduction agent is injected through a special catalyst into the exhaust stream of your truck diesel engine. How SCR works?

SCR Malfunction Icon This icon warns you that a malfunction has been detected in the DEF-SCR system. If this warning icon illuminates, stop the vehicle and contact your HINO dealer as soon as possible.

Selective catalytic reduction (SCR) means converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen (N 2), and water (H 2 O). A reductant, typically anhydrous ammonia (NH 3), aqueous ammonia (NH 4 OH), or a urea (CO(NH 2) 2) solution, is added to a stream of flue or exhaust gas and is reacted onto a ...

What is a SCR System Fault? A System Fault refers to a malfunction or failure in the Selective Catalyst Reduction system of a vehicle. The SCR system is responsible for reducing emissions by injecting diesel exhaust fluid (DEF) into the exhaust stream to react with nitrogen oxides (NOx).

Hino’s Selective Catalytic Reduction (SCR) system is standard on all Hino EPA 2010 models. The system fully complies with EPA 2010 standards by converting nearly all harmful exhaust gas emissions into nitrogen and water vapour.

Jan 22, 2025 · SCR, which stands for “Selective Catalytic Reduction,” is an after-treatment technology that uses catalysts to remove or decompose specific chemical components and facilitate chemical reactions. The SCR exhaust treatment system is applied to medium and heavy-duty Hino trucks, such as the Series 500 and Series 700, to reduce nitrogen oxide ...

Hino Trucks has adopted SCR and developed state-of-the-art technologies to implement emission controls that meet or exceed the 2010 EPA emissions standards with near-zero levels of all regulated particulates [0.01 g/hp-hr] and NOx, [0.2 g/hp-hr] …

Nov 17, 2015 · • Deterioration of SCR catalyst is determined by a decision of a drop in the NOx conversion efficiency and the DEF concentration. • Conversion efficiency is calculated by upstream and downstream NOx sensors.

May 13, 2020 · In this article, we will talk about Hino DPF delete, DEF delete, EGR delete, EGT delete and SCR delete and their benefits for your Hino truck or bus: The Diesel Particulate Filter, called DPF, has one main purpose – to reduce the diesel particulate matter or …

The regeneration control program of the HC-SCR catalyst for the exhaust emissions purification device is inappropriate, and there is a possibility that the sulfur component in the exhaust emissions that adheres to the catalyst will not be removed and may accumulate.
