Introduction

In the world of engines, whether it's for motorcycles or tricycles, the piston stands as a fundamental and indispensable engine part. Acting as a crucial link in the power - generation chain, the piston's primary function is to transfer the force generated by the combustion of fuel - air mixtures in the engine cylinder to the crankshaft via the connecting rod. This conversion of linear motion into rotational motion is what ultimately powers the vehicle forward.

Today, we are excited to introduce you to our high - quality Piston: 49/MAR90C, a product designed to meet the demanding requirements of motorcycle and tricycle engines.

The unique model number serves as an identifier, allowing customers to easily distinguish this piston from others in the market. It is engineered to be a perfect fit for engines with corresponding specifications, ensuring seamless integration and optimal performance. Whether you are a professional mechanic looking for replacement parts or a vehicle owner interested in engine upgrades, the 49/MAR90C model is a reliable choice that is recognized in the industry for its compatibility and quality.
 Key Dimensions
  • CYL DIA (Cylinder Diameter): The cylinder diameter of this piston is 52.4. This dimension is crucial as it determines the amount of fuel - air mixture that can be compressed and combusted within the cylinder. A precisely machined cylinder diameter ensures a proper seal between the piston and the cylinder wall, minimizing gas leakage. This, in turn, maximizes the efficiency of the engine's power - generation process. A larger cylinder diameter generally allows for more fuel - air mixture to be burned, potentially increasing the engine's power output, but it also requires a piston that can handle the increased forces and maintain a tight seal.

  • TOTAL HIGH (Total Height): With a total height of 39.4, this piston is designed to fit perfectly within the engine's cylinder assembly. The total height of the piston impacts the compression ratio of the engine. If the piston is too short or too tall, it can disrupt the proper functioning of the engine's valves and other components. The 39.4 - unit height ensures that the piston moves smoothly within the cylinder during the engine's four - stroke cycle (intake, compression, power, and exhaust), contributing to consistent engine performance.

  • COMP DIST (Compression Distance): The compression distance of 21.8 is another vital parameter. This distance affects the compression ratio of the engine, which is the ratio of the volume of the combustion chamber at the bottom - dead - center (BDC) to the volume at the top - dead - center (TDC). A proper compression distance is essential for efficient combustion. If the compression distance is incorrect, it can lead to issues such as poor fuel economy, reduced power, or even engine knocking. The 21.8 - unit compression distance of the 49/MAR90C piston is optimized to provide the right compression ratio for the target engines, ensuring smooth operation and good power delivery.

  • RING: The piston ring has dimensions of 1.01.02.0. Piston rings play a crucial role in the engine's operation. They seal the combustion chamber, preventing the escape of combustion gases from the cylinder into the crankcase. The 1.01.02.0 dimensions of the piston ring are designed to fit precisely around the piston and create an effective seal. The width and thickness of the piston ring are carefully engineered to withstand the high - pressure and high - temperature environment within the engine cylinder. A well - fitting piston ring also helps to control the oil consumption in the engine by scraping excess oil from the cylinder wall and returning it to the oil pan.

  • PIN DIA (Piston Pin Diameter): The piston pin diameter is 13. The piston pin connects the piston to the connecting rod, allowing the linear motion of the piston to be transferred to the rotational motion of the crankshaft. A proper - sized piston pin is essential for smooth power transmission. If the piston pin diameter is too small, it may not be able to handle the forces exerted on it, leading to premature wear or even failure. On the other hand, if it is too large, it can cause unnecessary friction and weight increase. The 13 - unit diameter of the piston pin in the 49/MAR90C piston is designed to provide a reliable connection between the piston and the connecting rod, ensuring efficient power transfer.

  • PIN LENGTH: The piston pin length is 41.5. The length of the piston pin affects its stability and load - bearing capacity. A longer piston pin can distribute the forces more evenly across the piston and the connecting rod, reducing the stress concentration points. This, in turn, can improve the durability and reliability of the engine. The 41.5 - unit length of the piston pin in the 49/MAR90C piston is optimized to provide sufficient support and stability while minimizing the weight and friction within the engine.



 Ring Specifications
The piston ring for the 49/MAR90C piston has dimensions of 1.01.02.0. These precise dimensions are carefully designed to fit snugly around the piston. The width of 1.0 and thickness of 1.0 are crucial for creating an effective seal between the piston and the cylinder wall. The 2.0 - unit length ensures that the piston ring can fully encircle the piston and maintain its integrity during the engine's operation. The piston ring is designed to have a specific clearance with the piston grooves. This clearance allows the piston ring to expand and contract slightly as it is subjected to the high - temperature and high - pressure environment within the engine cylinder. A proper fit between the piston ring and the piston is essential for optimal engine performance. If the piston ring is too loose, it can lead to gas leakage, reduced engine power, and increased oil consumption. On the other hand, if it is too tight, it can cause excessive friction, premature wear of the piston and the piston ring, and potentially engine overheating.
Function of Piston Ring
The piston ring serves several critical functions within the engine. Firstly, it acts as a seal. During the engine's operation, the combustion of the fuel - air mixture in the cylinder creates high - pressure gases. The piston ring is designed to prevent these high - pressure combustion gases from leaking from the combustion chamber into the crankcase. By forming a tight seal between the piston and the cylinder wall, the piston ring ensures that the full force of the expanding gases is exerted on the piston, driving it downward and generating power. This sealing function is crucial for maintaining the engine's compression ratio. A proper compression ratio is necessary for efficient combustion. If there is gas leakage due to a faulty piston ring, the compression ratio will be reduced, leading to poor fuel economy, decreased engine power, and even difficulty in starting the engine.
Secondly, the piston ring plays a vital role in heat transfer. The piston is exposed to extremely high temperatures during the engine's operation. The piston ring helps to conduct the heat from the piston to the cylinder wall. This heat transfer is essential for keeping the piston at a reasonable operating temperature. If the piston overheats, it can expand and seize within the cylinder, causing severe engine damage. By efficiently transferring heat away from the piston, the piston ring helps to maintain the structural integrity of the piston and ensures the smooth operation of the engine.
Finally, the piston ring also helps to control the oil consumption in the engine. It scrapes off the excess oil from the cylinder wall as the piston moves up and down. This prevents the oil from entering the combustion chamber and being burned, which could lead to increased emissions and reduced engine performance. At the same time, the piston ring also ensures that a thin film of oil remains on the cylinder wall to provide lubrication between the piston and the cylinder wall, reducing friction and wear. In summary, the piston ring is an essential component of the engine, and its proper functioning is crucial for the overall performance, efficiency, and durability of the engine.

For example, in a delivery tricycle that is constantly transporting heavy packages, the 49/MAR90C piston can provide the necessary power to climb slopes and navigate through traffic without experiencing a significant drop in performance.
Moreover, tricycles are often used in diverse road conditions, from smooth city streets to rough rural roads. The 49/MAR90C piston's durability and reliability make it suitable for these varying terrains. On rough roads, the engine may experience more vibrations and shocks. The piston's robust design can endure these vibrations, preventing premature wear and damage. Its well - designed piston ring also helps in maintaining the engine's performance in dusty or dirty environments. The piston ring effectively seals the combustion chamber, preventing dust and debris from entering the engine, which could otherwise cause abrasion and reduce the engine's lifespan. Whether it's a tricycle used for agricultural work in the countryside or a passenger - carrying tricycle in a bustling city, the 49/MAR90C piston can ensure stable engine operation, contributing to the overall reliability and efficiency of the tricycle.
