This "Conditioned Air System" is characterized by a cowl-mounted outside air receiver that passes fresh air through a heater core utilizing hot engine coolant for a heat source. [5] The Nash system also pioneered the use of slight pressurization within the passenger compartment to eliminate the infiltration of cold outside air during winter use ...
Another side effect of over-cooling is reduced performance of the cabin heater, though in typical cases it still blows air at a considerably higher temperature than ambient. The thermostat is therefore constantly moving throughout its range, responding to changes in vehicle operating load, speed, and external temperature, to keep the engine at ...

Blow-by, as it is often called, is the result of combustion material from the combustion chamber "blowing" past the piston rings and into the crankcase. These blow-by gases, if not ventilated, inevitably condense and combine with the oil vapor present in the crankcase, forming oil sludge. Excessive crankcase pressure can furthermore lead to ...
A parked car plugged in to an electrical outlet to power the block heater. Block heaters are frequently used in regions with cold winters such as the northern United States, Canada, Russia and Scandinavia. In some countries where block heaters are commonly used, carparks are sometimes fitted with electrical outlets for powering the block heaters.
