A tighter built home means less outside air infiltrating in the home, which means less oxygen to use for combustion within the furnace. As the furnace burns fuel and oxygen for combustion, it "eats up" surrounding air, which has to be "made up" with fresh air. If air cannot type in the home as easily anymore, this can cause serious issues. As the surrounding air is utilized for combustion, rather than substituted with oxygen, a negative pressure inside the space can happen. This could create combustion problems for the furnace, plus burn up fresh air for anybody inside the home. In terms of its specifications, Vette's V8 will need a stride or two for the downsizing road, providing a smaller displacement. GM has confirmed the latest units will feature tiotioaluminum blocks and heads, direct injection and also an efficiency-boosting combustion system. However, the upcoming powerplants will stay GM's overhead-valve design, which ensures you keep the development costs low and offers a compact layout. Also, Vette will have a capacity of 5.5 liters and definately will generate about 440 hp. 7. Using distractions
