Chaochai Company's 4102-CE4B State IV engine is based on the 4102-C3B with the BOSCH--EDC17CV54 electronically controlled fuel system, EGR+POC+DOC post-processing system, and upgraded to meet the national IV emission standard energy-saving high-speed engine.
In order to better use the performance of the engine, it is necessary to carry out the cold calibration test. The test vehicle matching this engine set off from Chaoyang on January 24 and arrived in Heihe on January 25. In order to catch up with the last cold spell on the eve of the Spring Festival to better complete the calibration task, the technicians of Bosch and Chaochai who were responsible for the calibration of the car began installing the measurement hydraulic system pressure and temperature on the evening of the test vehicle arrival in Heihe. And other equipment and calibration work. This year, all provinces across the country are experiencing the coldest year in 50 years. Heihe City is no exception. On January 27, the strongest cold current hits, and the ambient temperature of Heihe City is below -35°. Among them, the temperature is lowest in a few days. At -40°, many engine manufacturers such as Beijing Cummins, Nanjing Iveco, etc. did not succeed in starting at this ambient temperature, but the Chaochai 4102-CE4B State IV engine succeeded in setting fire to one time with excellent cold start performance. This result inspires confidence for the calibration personnel and enhances combat effectiveness. In order to make the entire vehicle reach an optimal status in a cold area, technicians of Bosch and Chaochai Company have a complete understanding of vehicle smoke, power, stability, and climbing performance. The post-processing system has been calibrated in various indicators such as adaptability in cold regions.
The high-calorie calibration successfully completed its mission, I believe that this engine in the fierce market competition will be able to firmly occupy a place, give full play to the characteristics and advantages of the DPRK diesel power, making high-quality power continue to take off in 2010 and continue to be brilliant!
High Strength Steel Tie Rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The steel tie rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as grade 460, grade 520, grade 550, grade 650, grade 785, grade 830, grade 930, grade 1080 etc.
