The hard starting problems of diesel engines in below zero / freezing temperatures originate from two factors. One is the original cold air being drawn in to the turbocharger and compressed in to the engine?s cylinder head. The second is the fuel itself, can also be cold which sub zero / freezing temperature fuel is sprayed in to the cold engine?s combustion chamber, where it mixes using the cold air drawn thru turbocharger. Lighting takes center stage in fashion photography and a photography light meter will assist you in planning the lighting for a shot. Ideally, the light should enhance the elements of the design and the shot. It can be kept minimal to create silhouettes or mood, or bright to increase the contrast. Some pictures may require a fill light added when shooting into the sun, while others prefer the effect without. An outdoor shoot during an overcast day assists in creating a mood and allows the shadows to play across her skin which adds interest to the shot. Today's building codes state spaces using furnaces have to have method for getting back together combustion air since it used. Newer homes have ducting installed, during construction, that literally brings fresh air from the outside for an area close to the furnace. This ducting, usually called comprise air duct, or combustion make-up air, is sized according to the capacity from the furnace.
