Diesel Engine Operation And Maintenance Guide

I.Overview

This series of small agricultural diesel engines features a direct injection fuel system, providing strong power, fuel efficiency, stable operation and easy maintenance. It is widely used as a power source for agricultural machinery such as feed pellet machines, straw cutters, grain crushers, hammer mills and wood crushers. Proper operation and regular maintenance help extend service life and ensure reliable performance.

III. Selection of Pulley Dimensions

When a diesel engine is matched with other working machinery, the selection of pulley dimensions directly affects the operating condition of the diesel engine and the production efficiency of the working mechanism. The pulley dimensions can be selected according to the following formulas:

When the diesel engine leaves the factory, according to the user's needs, it can be supplied with one V belt pulley, with a pitch diameter of 125 mm, for matching use.

There is also one flat belt pulley, with a diameter of 130 mm. The user can choose according to the required matching use, and whether it will be supplied should be confirmed when placing the order.

IV. Operation and Adjustment of Diesel Engines

1. Pre-operation Preparation

Two preparatory tasks must be completed before starting the diesel engine:

2. Starting

After completing the above preparatory work, perform a thorough inspection, then start the engine according to the following steps:

3. Stopping

After completing the above preparatory work, perform a thorough inspection, then start the engine according to the following steps:

4. Precautions for New Engine Operation

5. Precautions During Operation

6. Lubrication of the Diesel Engine

7. Post-Shutdown Precautions

8. Valve Clearance Adjustment

9. Decompressor Adjustment

Turn the decompressor handle clockwise with your left hand. If you feel firm resistance as the valve is depressed, and the engine turns easily, the decompressor is working properly.

If the condition is not as described above, perform the adjustment as follows:

VI. Maintenance of the Diesel Engine

Primary Maintenance

Primary maintenance shall be carried out after the diesel engine accumulates 100 operating hours:

Secondary Maintenance

The timing of secondary maintenance depends on the technical condition of the diesel engine. In addition to all items of primary maintenance, the following work shall be completed:

VII. Maintenance for Disused Diesel Engines

When the diesel engine will be out of service for an extended period, it must be preserved as follows to prevent corrosion damage.
