filter: Used to clean out impurities and debris from lubricants such as oil.
fluid friction: Occurs between a solid object and a gas or a solid object and a liquid.
friction: Created when two surfaces come into contact with each other, resulting in kinetic energy that becomes heat.
grease: A type of lubricant that is more viscous, or "thicker," than oil.
heat exchanger: A device that is used to transfer heat from fluids on one side of the exchanger to fluids on the other side of the exchanger, leading to cooling.
high risk lubricants: Lubricants that are at a higher risk of being involved in accidents or spills and can negatively impact the environment.
hybrid lubricants: A combination of solid and liquid lubricants.
hydrocarbons: Organic substances made up of only hydrogen and carbon.
hydrophobic: The ability to repel or an inability to combine with water.
internal combustion engines: Engines that use hot, expanding gases to move the engine's parts.
