Question

On turbocharged engines, the lubricating oil is frequently routed through an external oil cooler. The cooler prevents the oil from getting hot enough to oxidize and thicken, a process that begins when the oil reaches a temperatureof __________.

1) 100 degrees F
2) 150 degrees F
3) 200 degrees F
4) 250 degrees F

Answer 1

The oil oxidation and thickening process in turbocharged engines begins at 4) 250 degrees F, which can be mitigated by using an external oil cooler.

Step-by-step explanation:

On turbocharged engines, the process of oil oxidation and thickening begins at a temperature of 4) 250 degrees F. It is at this critical temperature that the oil's viscosity may become too low due to the increased kinetic energy of its molecules, compromising its effectiveness as a lubricant. Turbocharged engines often incorporate an external oil cooler to prevent the oil from reaching such high temperatures and to ensure the oil continues to lubricate effectively under varying operational conditions.
