How to see the installation direction of the piston mark

The top surface of the piston is marked with an arrow. When installing, the arrow should face the direction of the exhaust valve, that is, the front end of the vertical engine, which can reduce the impact of the piston on the cylinder wall.

How to tell if the piston is installed backwards?

When installing the piston, you need to pay attention to the grooves and various marks on the top of the piston. For pistons with asymmetric grooves on the top, it is a simple way to judge the grooves corresponding to the intake valve.

What is the sound of the engine piston pin

The reasons for the noise of the engine piston pin are as follows: 1. The noise is fairly clear at idle and mid-speed, with a rhythmic click and click; as the engine speed changes, so does the period of the sound.

What is usually marked on the top of the piston

Usually, the piston has a forward mark on it. The installation direction of the piston is strictly specified. Gasoline engine pistons have pits that avoid the valve, and diesel engine pistons have a design that avoids cooling nozzles.

The main reason for piston bias

The piston of an automobile engine will affect its service life, and even a cylinder pulling accident may occur in severe cases, making the engine unable to operate normally. Therefore, we should have a good understanding of the phenomenon, causes and elimination methods of engine piston-cylinder deviation.

What should be paid attention to when choosing a piston

The piston is determined according to the cylinder diameter level of the cylinder, which is indicated by a number or letter, and is usually located on the rear side of the cylinder block. Cylinder diameter grades are listed in cylinder order, and the first number or letter is the cylinder diameter grade of cylinder 1.

How to divide the direction when the piston is installed

Piston rings generally have letters or numbers, with one side facing up, no signs and no specific direction regulations, and oil rings are not divided into positive and negative sides.

What are the types of pistons

Since the pistons of internal combustion engines work under the conditions of high temperature, high pressure and high load, the requirements for the pistons are relatively high, so this article mainly discusses the classification of pistons of internal combustion engines.

What is a Piston?

Piston is the "heart" of an automobile engine, which is subjected to alternating mechanical and thermal loads, and is one of the key components in the engine with the worst working conditions. The function of the piston is to withstand the gas pressure and transmit it to the connecting rod through the piston pin to drive the crankshaft to rotate. The top of the piston is also an integral part of the combustion chamber.
