The circulating splash type of engine lubrication system is a simple and effective method of lubricating the moving parts of an engine.
Diagram:
1. Oil pan: The oil pan is located at the bottom of the engine and holds the engine oil.
2. Oil pump: The oil pump is responsible for circulating the engine oil throughout the engine. It draws oil from the oil pan and pumps it through the engine.
3. Oil galleries: The oil galleries are passages in the engine block and cylinder head that distribute the oil to the various moving parts of the engine.
4. Crankshaft: The crankshaft is a rotating shaft that converts the linear motion of the pistons into rotational motion.
5. Connecting rod: The connecting rod connects the piston to the crankshaft and transfers the linear motion of the piston to the crankshaft.
Operation:
1. The oil pump draws oil from the oil pan and pumps it through the engine.
2. As the crankshaft rotates, it splashes the oil around the engine, lubricating the moving parts such as the pistons, connecting rods, and crankshaft bearings.
3. The oil flows through the oil galleries to reach all the necessary parts of the engine.
4. The oil also helps to cool the engine by absorbing heat from the moving parts and carrying it away.
5. The oil eventually returns to the oil pan where it can be recirculated through the engine again.
Overall, the circulating splash type of engine lubrication system is a simple yet effective way to ensure that the moving parts of the engine are properly lubricated and cooled.

Circulating Splash Type of Engine Lubrication System
Diagram:
[Image of Circulating Splash Type Lubrication System]
Components:
- Oil sump
- Oil pump
- Oil reservoir
- Splash baffle
- Dippers
- Crankshaft
- Connecting rods
- Piston rings
Operation:
1. Oil Circulation:
- The oil pump draws oil from the sump and pumps it into the oil reservoir.
- From the reservoir, the oil flows through a passage in the engine block.
2. Splash Plate:
- The passage directs the oil onto a splash plate or baffle.
3. Splashing:
- The rotating crankshaft throws oil droplets into the crankcase as it swings.
- The splash baffle helps to distribute the oil droplets throughout the crankcase.
4. Dippers:
- Connecting rods are fitted with dippers that scoop up the oil droplets from the crankcase.
5. Lubrication of Bearings:
- The dippers carry the oil droplets to the crankshaft and connecting rod bearings, lubricating them.
- The excess oil drains back into the sump.
6. Piston Rings and Cylinders:
- As the pistons move up and down, their rings scrape against the cylinder walls, spreading the oil film.
- This lubricates the piston rings and cylinder walls.
Advantages:
- Simple and inexpensive.
- No external oil pipes required.
- Suitable for low-speed, low-power engines.
Disadvantages:
- Not suitable for high-speed, high-power engines.
- Does not provide consistent lubrication under all operating conditions.
- Can cause excessive oil consumption.
