An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [1] However, all common antifreeze additives also have lower heat capacities than water, and do reduce water's ability to act as a coolant when added to ...
The G11/G12 is the first 7 Series generation to feature a plug-in hybrid variant, called the 740e/740Le iPerformance. This new model effectively replaces the rather undersold ActiveHybrid 7 , which evolved from a 750i based mild hybrid to a 740i based full hybrid in 2014 post-LCI (Life Cycle Impulse) variant.
For instance for the EQE 350 4MATIC EV, Mercedes notes prices of $60/month, $600/year or lifetime cost of $1,950 to unlock an additional 60 horsepower (and improve 0-60 mph times to 5.1 seconds ...
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.
Once the coolant reaches the thermostat's activation temperature, it opens, allowing water to flow through the radiator to prevent the temperature from rising higher. Once at optimum temperature, the thermostat controls the flow of engine coolant to the radiator so that the engine continues to operate at optimum temperature.
The first engines relied on thermosiphon cooling alone, where hot coolant left the top of the engine block and passed to the radiator, where it was cooled before returning to the bottom of the engine. Circulation was powered by convection alone. Other demands include cost, weight, reliability, and durability of the cooling system itself.
Coolant oil may be limited to cooling objects under approximately 200–300 °C, otherwise the oil may degrade and even leave ashy deposits. Pure water may evaporate or boil, but it cannot degrade, although it may become polluted and acidic. Water is generally available should coolant need to be added to the system, but oil may not be.
Prior to the invention of the Welch plug, the core holes were sealed using pipe plugs. During the testing of a car, one of the pipe plugs backed out. In order to get back on the road, one of the Welch brothers installed a press-fit quarter or half dollar coin into the hole using a hammer. The design of the Welch plug was refined based on this ...
