A self-starter, also known as a starter motor, is an essential component in vehicles that initiates the engine’s operation. It functions by drawing electrical power from the battery to crank the engine, allowing it to start without manual effort.

In the context of engines and machinery, sleeves (often called cylinder sleeves or liners) are components that line the interior of the engine’s cylinder. They provide a durable, replaceable surface for the piston to move within, protecting the cylinder from wear and reducing friction.

An oil filter is a vital engine component that removes contaminants such as dirt, metal particles, and sludge from the engine oil. Clean oil is crucial for lubricating engine parts, reducing friction, and preventing wear.

A fuel lifting pump is a crucial component in the fuel system of diesel engines, designed to move fuel from the tank to the primary fuel pump or fuel injection system. It ensures that fuel is consistently supplied to the engine, maintaining the necessary pressure for proper combustion.
