Recently, news came Changchun FAW Sihuan Engine Manufacturing Co., Ltd. After several years of unremitting efforts to complete the development of new light truck class country â…£ CA4D28 country â…£ series high pressure common rail diesel engine. At present, the entire vehicle has been fully promoted and completed by several light truck manufacturers.
This model uses BOSCH high pressure common rail system + EGR technology route, based on the mature CA4D28 series models based on the development and design, retains the CA4D28 series diesel engine compact structure, low speed dynamics, good fuel economy, small size, light weight With long service life and other advantages, DOC+POC post-treatment meets National IV emission standards. Braking performance includes oil brakes and air brakes (exhaust brakes).
After several years of efforts by independent technology R&D teams, Changchun FAW Sihuan Engine, in addition to the launch of the CA4D28 IV Series diesel engine, also introduced the CA4N28C5 National V Series natural gas engine and the CA4D20TCI State IV diesel engine.
The CA4N28C5 national V series natural gas engine technology line is an electronically controlled gas system. The system adopts the technical route of supercharged intercooling, electronically controlled gas injection+mixer scheme, sequential single-cylinder independent ignition, air-fuel ratio closed-loop control+self-learning, meeting the national V emission level, adopting on-line diagnostic OBDII technology, and completing a series of OBDII function. The main adaptation models are three tons of light trucks, urban logistics vans, 6 to 7 meters of city buses, CMB buses and other modified vehicles.
The CA4D20TCI State IV diesel engine is a four-valve, dual overhead camshaft, hydraulic tappet, high pressure common rail, and supercharged intercooled diesel engine. The CRS2.2 oil supply system has lower combustion noise and more complete combustion of fuel oil. The requirements of IV and Euro V emission regulations have greatly improved the engine power while also having good fuel economy. The main matching models are SUVs and pickups.
1. Raw material pulverization: Raw materials are mainly divided into two categories, starch and fat. Starch is mainly various grains. Its pulverization can be achieved by ordinary pulverizers. It only needs to ensure the fineness and clean raw materials during the pulverization process. Hygiene can be. Use a colloid mill to pulverize into separate packs or puree, and the meat only needs to be pulverized into meat puree or powder with a colloid mill, and then added to the grain powder and stirred evenly.
2. Raw material mixing: The mixing equipment has two functions, one is to mix all kinds of raw materials evenly, and the other is to adjust the moisture and humidity. It is generally a vertical rapid mixer: the mixing time is short, the mixing is completed quickly, and the machine is used before the humidity of the raw material changes significantly, which ensures the uniformity and quality of the puffing of the dog food particles. The disadvantage is: the single-cylinder mixing capacity is small, and it needs to be stirred all the time during the production process.
3. Raw material extrusion, puffing and curing molding: The twin-screw extruder extrudes and extrudes under high temperature and high pressure, and produces dog food and cat food particles of different styles and shapes by changing different molds. For different raw material ratios and humidity, it is necessary to adjust the temperature and screw speed of different regions and the feeding speed of the feeder to ensure that the produced dog food particles are of high quality and good appearance.
