The hard starting problems of diesel engines in below zero / freezing temperatures are generated by two factors. One is the initial cold air being drawn in to the turbocharger and compressed in the engine?s cylinder head. The second is the fuel itself, is also cold and also this sub zero / freezing temperature fuel is sprayed to the cold engine?s combustion chamber, where it mixes while using cold air drawn thru turbocharger. This picture amazingly captures the think layer of clouds in the valley close to the south of Lake Como, northern Italy. In the above image, the dense cloud hides almost the valley and instead gives off some artificial lights that will make the town just like an opaque blanket. The village over distance is clearly seen out from the blanket. Diesel particulate filter, filters the particulate matter by forcing the exhaust gases to secure a ceramic wall flow filter. The ceramic wall flow filter has a porous wall and is single ended. When the spent gases are forcibly passed through the porous wall, the particulate matter is filtered as well as the gas is let loose thereby reducing the particulate emission in the atmosphere.
