4. The cylinder liner of a two-stroke diesel engine is arranged with an air port, which is opened and closed by a piston to realize gas distribution. There are several types of cylinder liner structure: Cylinder Liner Supplier For ISUZU,Cylinder Liner For Car,Cylinder Liner For ISUZU,Cylinder Liner For ISUZU Engine Parts,cylinder sleeve 1D auto parts , https://www.1dauto.com
The inner surface of the cylinder is easy to wear due to the action of high temperature and high pressure gas and the contact with the high-speed moving piston. In order to improve the wear resistance of cylinder and prolong the service life of cylinder, there are different cylinder structure forms and surface treatment methods. There are three types of cylinder structure: no cylinder liner type, dry cylinder liner type, wet gas cylinder liner type.
High Quality Coal Gasification/Coal Gasifier Design for Indonesia Coal or Other Coal
30% Energy Saving Coal Gasifier Generator
This model of coal gasifier is a new intelligent, high-efficiency, and environmentally friendly product developed by our company. It features a patented slag-removing revolving ash pan and an automatic slag removal system, ensuring smooth operation and minimal maintenance.
The unique pagoda-shaped heat-resistant iron grate ensures that the furnace wall is always protected by slags, enhancing slag-breaking, loosening, and ventilation performance. This design breaks away from the traditional concept of coal gasifiers being similar to pressure vessels, while enabling automatic temperature control for more stable and efficient operation.
**Working Principle of Coal Gasifier:**
The coal gasifier uses 10–50mm pea coal as an ideal fuel, significantly increasing the gasification intensity, accelerating the reaction process, and improving the gasification efficiency of coal. The carbonized coal reacts with steam to produce combustible gases such as carbon monoxide and hydrogen, achieving complete gasification and continuous, stable gas production.
**Environmental Benefits:**
Tested by the Henan Environmental Testing Center, this coal gasifier produces no smoke during combustion. The emissions of sulfur dioxide and soot comply with the GB9078-1996 environmental standards, making it a clean and eco-friendly solution.
**Safety and Reliability:**
Equipped with national invention patent technology, this coal gasifier eliminates the risk of explosion commonly found in traditional models, offering a safer and more reliable option for industrial use.

The Cylinder Liner is a cylindrical part that is placed in the cylinder block hole of the body and is secured by the cylinder head. The piston reciprocates in its inner hole and is cooled by cooling water outside.
The functions of the cylinder liner are:
1. Together with the cylinder head and piston, it forms the cylinder working space.
2. The cylinder liner of the cylinder piston diesel engine is the lead of the reciprocating movement of the piston, which is subjected to the side thrust of the piston.
3. The heat of the piston assembly and itself is transferred to the cooling water to make the working temperature appropriate.
