While diesel engines offer better fuel economy, long-term durability and lower greenhouse gas emissions than gasoline engines, concerns are growing about the environmental and health hazards posed by their exhaust emissions. Diesel emission technologies are primarily concerned with the reduction in both particulate matter and NOx. However, by tuning the engine to minimise NOx formation, fuel consumption and particulate emissions will go up. This delivers a conflict of interests. Thus there are two methods of reducing diesel emissions:
ptimise the engine to run at low PM generation (which increases NOx formation) and add a NOx abatement system. This system delivers lower fuel consumption and CO2 levels.
Optimise the engine to run at low NOx generation and add a PM abatement system (DPF). This system increases fuel efficiency (power) and CO2 emissions. Diesel particulate filters are being used worldwide to control particulate emissions from many diesel-powered urban buses, trucks, forklifts, locomotives and other vehicles
A Diesel Particulate Filter (DPF) reduces the particulate mass in the exhaust gas stream by capturing the ultra fine particles. DPF applications are different from catalytic converter systems as the gas stream passes through the porous walls of the substrate as opposed to flowing through the channels. Thus the backpressures on the system are much higher. DPF substrates are also heavier than catalytic converter substrates thus requiring different mat holding properties. The solutions is to have a non-intumescent support mat. The benefit are:
Prevents filter slippage caused by heavy substrate and high back pressure.
Designed for both low temperature operation and high temperature regeneration.
