| 1.The Role of Engine Oil |
Q: Why is engine oil necessary? |
| A1: Inside the engine, metal parts move very rapidly in contact with each other, causing frictional heat. Unless this friction is reduced, the engine will fail. The engine oil's main job is to reduce friction by forming a film on the metal surfaces. It has other functions, too. |
| 1. |
Enables smooth engine operation by reducing friction between engine parts. |
| 2. |
Helps prevent overheating by carrying away heat from the inside of the engine. |
| 3. |
Keeps the inside of the engine clean by carrying away contaminants (products of combustion, etc). |
| 4. |
Prevents leaking of combustion gases by filling gaps between the piston ring and cylinder wall. |
| 5. |
Rust & Corrosion Prevention |
| Q: Can you use any type of engine oil? |
| A2:You cannot. To obtain the performance required of engine oil, additives with various functions are added to a highly refined oil. |
| Diesel engines tend to produce more acid than gasoline engines. They therefore require special oil containing a strong alkalizing agent to neutralize acidity, and a high performance cleaning agent that prevents carbon from sticking to high-temperature parts. |
|
Engine oil is essential to the proper operation of engines running
under the severe conditions of high temperature and high speed. |
Diesel engine oil is particularly susceptible to contamination by soot and by the
by-products of diesel fuel constituents (oxidized and carbonized substances), promoting its deterioration. Therefore, unless the specified engine oil is used, engine problems tend to increase. |
