Product Introduction of Plastic Diesel Engine Oil Gas Separators
The plastic diesel engine oil air separator is a lightweight innovative design that reconstructs the engine's "breathing purification" scheme. While maintaining efficient separation performance, it brings a more suitable choice for small and medium displacement diesel engines, balancing economy and reliability.
Lightweight and strong, suitable for small and medium power scenarios
Adopting reinforced glass fiber nylon (PA66+30% GF) injection molding, the shell weight is only 0.8kg, which is 50% less than cast iron, directly reducing engine load and vibration transmission. This material has undergone high and low temperature cycling tests at -40 ℃~130 ℃ without cracking, with an impact strength of 80kJ/m ². It can cope with vibration and temperature fluctuations in non extreme working conditions such as agricultural machinery and small generator sets. The built-in separation components are also made of oil resistant engineering plastics, and the splicing gaps are eliminated through integrated injection molding technology to avoid electrochemical corrosion problems of metal parts, making them particularly suitable for dusty and humid field work environments.
Biomimetic separation structure, efficient oil locking without compromise
Continuing the three-level separation logic but optimizing the structural design: the first stage adopts a honeycomb shaped plastic filter with a precise pore size control of 5 μ m, which intercepts large oil droplets while reducing airflow resistance; The second level innovation is the "spiral air guide plate", which utilizes the easy formability of plastic to create denser swirling channels, allowing 2-5 μ m oil mist to efficiently condense under centrifugal force; The third level is equipped with a plastic based nano hydrophobic film, which is perfectly integrated with nylon substrate, and still maintains a capture rate of over 96% for oil vapor below 1 μ m. Tests have shown that on a 4L displacement diesel engine, oil consumption is reduced by 30% compared to traditional plastic separators, approaching the separation efficiency of cast iron models, and the oil change cycle can be extended by 15%.
Flexible adaptation, easier installation and maintenance
Design multiple specifications for small and medium-sized diesel engines (1.5-6L): a dedicated version for microcomputers (1.5-2.5L) with a 30% reduction in volume, suitable for models such as Changchai 485 and Yunnei YN33, and can be directly installed on the side of the valve cover; The mid-range engine (3-6L) is equipped with a heat-insulating skirt, compatible with engines such as Jiangling JX493 and Chaochai CY4BK, to avoid the high temperature of the exhaust pipe affecting the separation efficiency. The plastic shell comes with an elastic buckle, which does not require precise alignment during installation. It can be easily fixed by pressing lightly, with an error tolerance of 1mm, saving 50% of installation time compared to metal models. No special tools are required for maintenance. Simply unscrew the plastic end cap to replace the filter and hydrophobic film, and the accessory cost is only 60% of the metal version.
From tractors in orchards to light trucks for suburban distribution, this plastic diesel engine oil gas separator demonstrates its "lightweight yet efficient" performance: in small and medium power scenarios, it can not only protect the engine at lower costs, but also reduce daily operational burden for users through lightweight and easy maintenance, making every start-up more worry free and economical.
