Because the heater core cools the heated coolant from the engine by transferring its heat to the cabin air, it can also act as an auxiliary radiator for the engine. If the radiator is working improperly, the operator may turn the heat on (together with the cabin blower fan placed on full speed, and with the windows opened) in the passenger ...
Only the fixed parts of the engine, such as the block and head, are cooled directly by the main coolant system. Moving parts such as the pistons, and to a lesser extent the crankshaft and connecting rods, must rely on the lubrication oil as a coolant, or to a very limited amount of conduction into the block and thence the main coolant. High ...
The most common type of block heater is an electric heating element in the engine block, which is connected through a power cord often routed through the vehicle's grille. Some block heaters are designed to replace one of the engine's core plugs and therefore heat the engine via the coolant. [4] Alternative methods of warming an engine include: [5]
Baldhill Dam is a dam in Barnes County, North Dakota, [2] about 10 miles (16 km) north-northwest of Valley City in the eastern part of the state.. The earthen and concrete dam was constructed in 1951 by the United States Army Corps of Engineers with three tainter gates, a height of 60 feet (18 m), and 1,800 feet (550 m) in length at its crest.

The block heater may replace one of the engine's core plugs, or may be installed in line with one of the radiator or heater hoses. The block heater, first known as a head bolt heater, was invented in 1945 by Andrew Freeman in Grand Forks, North Dakota. Freeman used some scrap hoses and copper tubing onto the heating element of an old flat-iron ...
The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, [1] [2] having received a radiator patent in 1857, [3] but American Joseph Nason and Scot Rory Gregor developed a primitive radiator in 1841 [4] and received a number ...
This was illustrated by the 2013 Lac-Mégantic rail disaster, in which a unit train carrying 77 tank cars full of highly volatile Bakken oil through Quebec from North Dakota to the Irving Oil Refinery in New Brunswick derailed and exploded in the town centre of Lac-Mégantic. It destroyed 30 buildings (half the downtown core) and killed 47 ...
Shadehill Reservoir is a reservoir on the Grand River in Perkins County, South Dakota, USA. The lake was created by the construction of Shadehill Dam by the United States Bureau of Reclamation in 1951. [3] The reservoir has two primary inflows: North Fork Grand River and South Fork Grand River. The single Grand River serves as the only outflow.
