GLOBAL DIESEL ENGINE EXHAUST AFTER-TREATMENT MARKET

INTRODUCTION

Particularly earlier Euro VI compliance applications, after-treatment technologies such as EGR and SCR are commonly considered as the best option. While these are tried-and-true methods for lowering Exhaust emissions, each has its own set of trade-offs.

. To put it another way, it's a device that cleans exhaust gases so that engines can meet emission standards.

The exhaust gas contains hazardous emissions that travel from the turbo's exhaust side to the aftertreatment system.

GLOBAL DIESEL ENGINE EXHAUST AFTER-TREATMENT MARKET DEVELOPMENTS AND INNOVATIONS

Vehicle exhaust headers have three major functions: they guide exhaust air out from the engines, they generate noise produced by high-velocity exhaust gases, and they clean up dangerous emissions. Engine manifold, powerplant down pipe, catalytic converter, muffler, and tail pipe are the five components of a vehicle exhaust system.

The global market for vehicle exhaust systems is expanding at a steady pace. Changing emission requirements in various places throughout the world are mostly driving this growth.

The volume of permitted emissions from automotive exhaust systems has been reduced as a result of recent emission rules, and as a result, exhaust system manufacturers have been investing extensively in R&D for technologically improved exhausts that comply with the new guidelines.

As a result of the revised emission standards, after-treatment equipment are now required. These assist OEMs in controlling vehicle emissions and reducing damaging greenhouse gas emissions.

COMPETITIVE LANDSCAPE

The emissions from diesel filter (DPF) captures diesel particulates in the exhaust of a diesel engine. This filter can become blocked with time. The DPF should indeed be cleaned on a periodic basis to identify that it continues to operate properly.

It is critical that drivers pay attention to the warning indicators and symbols on the exhaust system. These bulbs alert the driver to take steps to ensure the emissions control system's health. It can cause system damage and derate circumstances, such as torque and speed reductions, if ignored. 

Cummins Inc. is a leading mobiliser of the aftertreatment modules in the market. The latest integration has been the Diesel Particulate Filter (DPF) in the Cummins Particulate Filter gathers and oxidises carbon to eliminate particulate matter (PM) by more than 90%; the Combustion Catalyst (DOC) in the Cummins Particulate Filter aids in this process.

The exhaust from the turbo flows via the DOC before entering the DPF. There is still nitric oxide (NO) and nitrogen dioxide (NO2) in the emissions after recovering the particulates from of the gasses in the DOC and DPF.

Delphi Automotive  is part of the component manufacture trending companies in the current industry. The Diesel Fuel Reformer System, a catalytic partial oxidation device in development at Delphi Corp., provides a new technique for achieving diesel exhaust aftertreatment goals for vehicle and diesel engine makers.

The device turns diesel fuel into reformate, a hydrogen- and carbon monoxide-rich stream of gas, using a catalytic partial oxidation process. To promote optimal regeneration and desulfation, the reformate can be injected directly into the vehicle's exhaust system.
