On February 9th, 2011, on the eve of the Spring Festival, the first batch of Beijing Bus Ecobuses loaded with the Cummins ISB 6.7-liter Euro 5 emission engine was officially put into operation. This is also the first batch of Euro V power products that have been verified in the international market for domestic bus markets. In 2007, Cummins took the lead in launching an engine series that meets Euro 5 emission standards in the global market, and its global sales volume has exceeded 20,000 units. The performance of the Cummins Euro 5 engine has been further improved. By improving the turbocharger system and optimization of in-cylinder combustion, the high altitude adaptability is improved, the fuel economy is more excellent, the low-speed stability is stronger, the emissions are cleaner, and the nitrogen oxide emissions are comparable. Compared to the first phase, it is reduced by more than 40%. Cummins needs no complicated structural adjustments to the engine and the vehicle. Only by updating the electronic control system of the engine, increasing the injection pressure of the fuel system, and increasing the injection volume of the discharged treatment liquid, the Euro 5 upgrade can be achieved, and the vehicle matching is further improved. Optimization, installation and operation are more convenient and cost is lower.
Since 2001, Cummins has introduced highly intelligent electronically controlled engine technology and products to China, and established high-standard product technology exchange platforms with major domestic passenger car companies such as Jinlong, Yutong, Futian, and Haige to upgrade the emission of domestic brand passenger cars. The overseas expansion provided sufficient technical reserves. In the process of matching and upgrading the Euro III and Euro 4 to Euro 5 vehicles, a large number of excellent electronically controlled engine technicians and service backbones were trained for the country, and the most advanced technology was unwaveringly advanced. The technology and products are continuously introduced into the Chinese market.
In the domestic bus market, Cummins uses in-cylinder combustion optimization and selective catalytic reduction (SCR) to meet Euro IV and Euro 5 emission standards. The Euro V emission standard requires that nitrogen oxides (NOx) and particulate matter (PM) emissions be reduced to 2 grams per kilowatt-hour and 0.02 grams per kilowatt-hour, respectively. SCR technology can bring better fuel economy, longer maintenance intervals, and higher reliability to the engine.
The Cummins ISB 6.7-liter fully electronically controlled engine (185-300 hp) is a proven classic model in the international and domestic markets, with unparalleled reliability and durability, and its global engine base B-Series product holds more than 700 Million Taiwan, ISB sales in Europe more than 100,000 units. While adhering to the superior power and cycle operating cost advantages of the Euro IV product platform, the ISB 6.7 engine further enhances the engine's fuel economy, reduces noise and emissions, and creates greater profitability for users worldwide. .
Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.
