1.11. Knowing the parts of a vehicle: Lubrication system

Página 12

A vehicle's lubrication system is an essential part of the engine's operation. He is responsible for reducing friction between the moving parts of the engine, which helps prevent excessive wear and overheating. In this chapter, we'll explore in more detail the lubrication system, its parts, and their role in maintaining a vehicle.

1. What is the Lubrication System?

The lubrication system is a system designed to provide a layer of oil between the moving parts of the engine, such as the pistons, crankshaft and valves. This oil serves to reduce friction between these parts, which helps prevent excessive wear and overheating. The oil also helps to clean the engine, removing dirt and debris that can build up while the engine is running.

2. Lubrication System Components

The lubrication system is made up of several parts, including the oil pump, crankcase, oil filter, oil passages, oil injectors, and the oil itself. Let's take a closer look at each of these components.

Oil Pump

The oil pump is the heart of the lubrication system. She is responsible for pumping crankcase oil to the rest of the engine. Most oil pumps are driven directly by the crankshaft or timing chain.

Carter

The crankcase is the engine oil reservoir. It is usually made of metal and is located at the bottom of the engine. The crankcase contains the oil when the engine is not running and provides an oil supply to the oil pump when the engine is running.

Oil Filter

The oil filter is an important part of the lubrication system. It is responsible for removing dirt and debris from the oil before it is pumped into the rest of the engine. This helps keep the engine clean and extends oil life.

Oil Passages

The oil passages are the channels that oil uses to travel from the crankcase to the rest of the engine. These passages are usually made of metal and are located throughout the engine.

Oil Injectors

The oil injectors are small valves that spray oil onto the moving parts of the engine. They are generally controlled by oil pressure and are designed to deliver a precise amount of oil to each part of the engine.

3. Lubrication System Maintenance

Regular maintenance of the lubrication system is essential for engine longevity. This includes checking the oil level regularly, changing the oil and oil filter regularly, and checking the oil passages to ensure they are free of debris.

It is important to remember that not only the quantity, but also the quality of the oil is crucial. Using a high quality engine oil can extend engine life and improve engine performance.

In short, the lubrication system is a vital part of a vehicle's engine. It plays a crucial role in reducing friction between moving engine parts, cleaning the engine and maintaining engine temperature. Regular lubrication system maintenance is essential to keep your vehicle running efficiently and reliably.
