Carbon build-up in the intake manifold will occur when blow-by gases are allowed to permanently contaminate the intake air because of a failing PCV system. [12] Carbon build-up or oil sludge from blow-by gases on intake valves are usually not a problem in port injected engines. This is due to the fact that the fuel hits the intake valves on the ...
The ignition source of a diesel engine is the heat generated by the compression of the air in the cylinder, rather than a spark as in gasoline engines. The dieseling phenomenon occurs not just because the compression ratio is sufficient to cause auto-ignition of the fuel, but also because a hot spot inside the cylinder (spark plug electrode ...
Unlike the Westerlies, these prevailing winds blow from the east to the west, and are often weak and irregular. [45] Because of the low sun angle, cold air builds up and subsides at the pole creating surface high-pressure areas, forcing an equatorward outflow of air; [46] that outflow is deflected westward by the Coriolis effect.
With the advent of advanced emission controls and more advanced fuel injection methods, modern vehicles do not have a thermostatic air intake system and the factory-installed air intake draws unregulated cold air. Aftermarket cold air intake systems are marketed with claims of increased engine efficiency and performance. The putative principle ...
This saves power, since the engine does not have to fully drive the fan. However, if engine temperature rises above the clutch's engagement temperature setting, the fan becomes fully engaged, thus drawing a higher volume of ambient air through the vehicle's radiator, which in turn serves to maintain or lower the engine coolant temperature to an ...
And while cold temperatures take the air out of all tires, freezing conditions impact EVs a lot more than hybrid or internal combustion cars because EVs are generally much heavier than cars with ...
Here’s what the experts say. If you’re over the age of 30, you likely remember your parents and grandparents warming up their cars before driving them during cold weather. You might even ...
