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 ...
Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...
A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.
Jerry Boylan was convicted by a federal jury in connection with the 2019 fire that killed 34 people on the Conception dive boat.
The Coast Guard has announced new safety rules following a deadly blaze that killed 34 people on a scuba diving boat off the California coast more than two years ago, including installation of ...
Hydrolock most commonly occurs in automobiles when driving through floods, either where the water is above the level of the air intake or the vehicle's speed is excessive, creating a tall bow wave. A vehicle fitted with a cold air intake mounted low on the vehicle will be especially vulnerable to hydrolocking when being driven through standing ...

Fire protection of such boats is provided by insulation and a sprinkler system which has a pipe system on top, through which water is pumped and sprayed to cool the surface while the boat is driven clear of the flames. This system, while not failsafe against engine failure, allows fireproof lifeboats to be built of fiberglass. [citation needed]
