Illustration 2 g06382836The first filter media that exhaust gas is exposed to is the DOC, a flow through style filter. The DOC oxidizes hydrocarbons, carbon monoxide, and soluble organic fractions as the exhaust gas flows through the filter. There are two temperature sensors, one at the inlet of the DOC canister, and one at the outlet of the DPF. These two sensors are used to make sure DOC is hot enough to oxidize efficiently. The DPF outlet temperature is also used by ECM to know that the exhaust leaving the DPF and entering the SCR.The DPF is a catalyzed ceramic filter which traps particulate matter (soot). The trapped soot is cleaned from the DPF through a catalytic reaction by heating the filter through a process called regeneration. The inlet section of the DPF cannister contains the DPF inlet pressure sensor, and DPF delta pressure sensor. The DPF Inlet Pressure sensor is used to measure the backpressure being generated by the DPF. The delta pressure sensor is used to measure soot collected in the DPF. The delta pressure sensor is measuring the pressure drop across the DPF. Since the delta pressure sensor is measuring flow resistance across the DPF, the sensor will also detect ash loading.Once the exhaust gas flows through the DPF, the exhaust gas enters the SCR mixing tube where Diesel Exhaust Fluid (DEF) is injected for the SCR. After the exhaust gas flows through the DPF, the gas enters the SCR. The DEF injected prior to the SCR, mixes with exhaust gas in SCR to reduce Nitrogen Oxides (NOX). DEF contains deionized water and urea, which turns to ammonia when heated. The ammonia reacts with the SCR catalyst to convert NOX into harmless nitrogen and water vapor. At the inlet of the SCR cannister is the SCR inlet temperate sensor. This sensor is used to make sure that the temperature is hot enough in the catalyst for DEF dosing to occur.Compact Clean Emissions Module (CEM)

A flexible exhaust pipe connects the engine to the Clean Emissions Module (CEM). The CEM contains the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF) and the Selective Catalytic Reduction (SCR) systems. The CEM contains several mechanical and electrical components that reduce various exhaust emissions emitted from the engine. All the systems on the CEM are controlled by the engine ECM. Exhaust gases entering the CEM flow through the DOC first, then the DPF and SCR.

Air Flow through CEM Package
The first filter media that exhaust gas is exposed to is the DOC, a flow through style filter. The DOC oxidizes hydrocarbons, carbon monoxide, and soluble organic fractions as the exhaust gas flows through the filter. There are two temperature sensors, one at the inlet of the DOC canister, and one at the outlet. These two sensors are used to make sure DOC is hot enough to oxidize efficiently. The DOC outlet temperature is also used by ECM to know that the exhaust leaving the DOC, and entering the DPF, is hot enough for regeneration to begin. There also two ports on the DOC that can be used to hook up a delta pressure sensor for troubleshooting.Once the exhaust gas flows through the DOC, the exhaust gas enters the SCR mixing tube where Diesel Exhaust Fluid (DEF) is injected for the SCR. Before the SCR, exhaust gas enters the DPF. The DPF is a catalyzed ceramic filter which traps particulate matter (soot). The trapped soot is cleaned from the DPF through a catalytic reaction by heating the filter through a process called regeneration. The inlet section of the DPF cannister contains the DPF inlet pressure sensor, and DPF delta pressure sensor. The DPF Inlet Pressure sensor is used to measure the backpressure being generated by the DPF. The delta pressure sensor is used to measure soot collected in the DPF. The delta pressure sensor is measuring the pressure drop across the DPF. Since the delta pressure sensor is measuring flow resistance across the DPF, the sensor will also detect ash loading.After the exhaust gas flows through the DPF, the gas enters the SCR. The DEF injected prior to the DPF, mixes with exhaust gas in SCR to reduce Nitrogen Oxides (NOX). DEF contains deionized water and urea, which turns to ammonia when heated. The ammonia reacts with the SCR catalyst to convert NOX into harmless nitrogen and water vapor. At the inlet of the SCR cannister is the SCR inlet temperate sensor. This sensor is used to make sure that the temperature is hot enough in the catalyst for DEF dosing to occur.Engine Throttle Valve and HC Dosing Regeneration
Illustration 7 g06258348
(1) Engine Throttle ValveMostly, regeneration is achieved passively, which means no added fuel to achieve regeneration. This is achieved by an engine throttle valve. The engine throttle valve is a butterfly valve located between the charger cooler outlet and the inlet manifold. This valve is the primary means of regeneration. The engine throttle valve is controlled by the ECM and is used to restrict the flow of air into the inlet manifold and the combustion chamber. This restriction increases the exhaust gas temperature and is used to control the DOC and SCR temperature to ensure emissions compliance in all operating conditions.If passive regen
