Functions of Lubricants

There are FIVE main functions of lubricants: Reduce Wear: Fluid lubricants maintain a film between parts to reduce friction and prevent surface-to-surface contact. Surface contact causes wear and for the surfaces to weld together. Cool Surfaces: Lubricants remove the heat produced by friction when acting as a heat transfer medium, or coolant. Heat must be removed to prevent damage of other surfaces. Cooling mechanical parts is an important function of any lubricant. Clean Surfaces: Lubricants flush debris from surfaces and carry it away. This can then be filtered out of the lubricant. By carrying away debris, lubricants prevent it from blocking oil passages and damaging parts. Since lubricants are circulated around mechanical parts, they are a logical choice for a cleaning agent. Seal Parts: Fluid lubricants fill open areas between moving surfaces. This provides a SEAL that prevents foreign matter from passing between moving surfaces. Keeps material from getting between surfac ... read more

Wiring Harness

Wiring Harness

The following is a typical wiring harness in a car:       There are multiple proprietary standards for communication in a car, including analog signals on wires, CAN, FlexRay, MOST, and LVDS.     There are multiple proprietary standards for communication in a car, including analog signals on wires, CAN, FlexRay, MOST, and LVDS. Each vehicle component typically has its own dedicated wiring and communication requirements. Due to this complex cabling, the wiring harness is the 3rd highest cost component in a car (behind the engine and chassis). Harnesses are built one at a time, and comprise 50% of the cost of labor for the entire car. The wiring harness is also the 3rd heaviest component (behind chassis and engine). Any technology that reduces this weight directly contributes to fuel economy
