Lubricant Viscosity & Engine Start Explained

advertisement

Definition: The viscosity of a lubricant measured under high-temperature and highshear conditions (typically at 150°C and under a shearing force of 1 million s^-1).
This measurement is crucial for determining the lubricant's performance in highstress, high-temperature environments, like in modern engines.

Importance: Ensures that the oil maintains a protective film in critical areas, such as
bearings and camshafts, under severe conditions.
Cold Cranking Simulator (CCS) Viscosity:

Definition: The viscosity of an oil measured at low temperatures (e.g., -25°C or 30°C) to simulate cold-start conditions in an engine.

Importance: Indicates how well an oil will flow and provide lubrication during engine
startup in cold weather. Lower CCS viscosity means easier starting and less strain on
the engine and battery.
Starting the Engine:

The battery provides the necessary electrical power to start the engine. When you
turn the ignition key or press the start button, the battery sends a high-current
electrical flow to the starter motor. The starter motor cranks the engine, allowing it to
begin the combustion process.

An alternator is a key component in a vehicle's electrical system. It is a type of
generator that converts mechanical energy from the engine into electrical energy in
the form of alternating current (AC). This electrical energy is used to recharge the
vehicle's battery and power all electrical components and systems while the
engine is running.

Park" (automatic transmission) or
"Neutral" (manual transmission).
