The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
A cold start can be difficult for an engine due to higher viscosity of oil and fuel in cold temperatures. Generally speaking, diesel engines have more difficulty starting at low outside temperatures than gasoline engines, and electric engines have the most problems. Diesel engines do not use spark plugs to ignite the air fuel mixture and rely ...
Once the engine is running, some cars continue to use the glowplugs until the engine has reached its operating temperature, in order to reduce the diesel exhaust emissions. Similarly, some engines re-activate the glowplugs if the temperature of an engine under light loads reduces below a certain threshold, in order to improve the efficiency of ...
A block heater is used in cold climates to warm an engine prior to starting. They are mostly used for car engines; however, they have also been used in aircraft engines. The most common design of block heater is an electrical heating element embedded in the engine block.
When temperatures drop, EV owners face a physics problem: Reduced battery performance and increased charging times. Fuel economy is 8% lower at 20 degrees than it is at 75 degrees in EVs ‒ and ...
This week’s winter storms are tracking to the south, and cold air will likely be present as far south as Georgia, said Jon Palmer, a meteorologist with the National Weather Service in Gray, Maine.
