How to install and distinguish the piston and connecting rod of single cylinder diesel engine? Anyway, how to install correctly and quickly. Thank you.

The small end of the connecting rod has an upward oil hole, so that splashed oil can enter the copper sleeve of the connecting rod to lubricate the piston pin. There are three kinds of common pistons: the first kind of flat-topped piston has a flat top and is a neck. The second kind of dust shovel piston shovels dust upwards. In the third type of direct injection piston, the top of the piston is directly made into a combustion chamber.

Matters needing attention

1. When starting manually, open the pressure reducing valve on the cylinder to communicate with the outside world, thus reducing the air pressure in the cylinder. Only in this way can we be shaken. In this way, the kinetic energy of the flywheel increases with the increase of the rotational speed.

When it reaches a certain speed, the crank is withdrawn, the pressure reducing valve is released, and the inertia of the flywheel is used to push the piston to move. At this time, the cylinder forms a closed space, the piston compresses air, the pressure in the cylinder rises, and the temperature rises, which can reach the ignition point of diesel oil and start the diesel engine.

2. When starting manually, in order to prevent the diesel engine from reversing and hurting people, when turning the diesel engine crank, you must hold the crank with your five fingers together. When the crank is started, be sure to hold the handle tightly, lean forward as far as possible, and raise your head, first slowly and then quickly. Hold the crank tightly after starting. It is forbidden for two people to hold the crank together to start, and it is forbidden to weld or make the crank.
