Diesel Engines Glow plug PI-49 for ISUZU 4JB1

  Do you know the structure and principle of the engine Glow plug?   The engine Glow plug plays an extremely crucial role in the start-up process of diesel engines, especially in cold weather conditions. Its main function is to provide the necessary thermal energy for the engine to start, helping the engine to start smoothly.   Next, let's take a closer look at its structure and working principle.   Structurally speaking, the common Glow plug is mainly composed of a resistance coil, a metal casing and the insulating material inside.   The resistance coil is the core heat-generating component of the preheating plug. When current passes through, it generates heat. The metal casing serves to protect the resistance coil and conduct heat. The insulating material filled inside is of vital importance. It can prevent the resistance coil from coming into contact with the inner wall of the metal casing due to vibration during engine operation, thus avoiding faults such as short circuits.   T…
