Scania, known as the king of highways, has always attached great importance to the development of its engine technology. Scania's wide range of engine products can provide customers with the widest range of choices, with products meeting Euro 3, Euro 4 and Euro 5 emission standards. Scania is the first manufacturer to supply trucks and city buses that match the European Environmentally-Friendly Vehicle Emission Standard (EEV) engine. The launch of the Scania Euro 5 emission standard engine series new product was two years earlier than the European legislation required to formally implement the Euro 5 emission standard in October 2009.
Scania's users can choose different types of products to meet their needs in a specific geographical area or specific situation. Products that meet Euro 5 emission standards include 9-liter, 13-liter, and 16-liter diesel engines with power ranging from 230-620 hp. In addition, Scania also offers 230 hp and 280 hp diesel engines and a 270 hp ethanol engine to meet the most stringent European environmental friendly vehicle emission standards for current emission control requirements. Scania also provides 230- to 620-horsepower engines that meet the Euro 4 emission standards, which are 230 horsepower – 580 horsepower, which meet Euro 3 emission standards.
The new Euro 5 emission standard engine platform optimizes product performance using Scania Exhaust Gas Recirculation (EGR) systems and Scania Ultra High Pressure Fuel Injection System (XPI). The Scania Technology Center in Södertälje, Sodertalje, Sweden, has been developing a five-year research and development project, hoping to enable the product to meet the needs and goals of performance and fuel consumption. At the same time, Scania continues its commitment to environmental protection, product reliability and ease of operation.
Scania's unique Euro 5 standard engine platform does not require the use of AdBlue additives (diesel-specific urea reducing agents) or other forms of exhaust aftertreatment. Jonas Hofstedt, head of research and development at Scania Power Systems, commented: “The use of AdBlue can generate noise, especially for small users. By adopting the exhaust gas recirculation technology in the combustion stage, not only low emissions are achieved, but also the need for exhaust gas system post-processing equipment is eliminated. â€
Scania Euro 5 standard exhaust gas recirculation technology has been continuously improved, and its engine efficiency and performance have been further improved. In addition to the water cooler, the exhaust gas recirculation system also adds an air cooler for exhaust gas cooling, lowering the combustion temperature, and reducing the formation of nitrogen oxides (NOx).
“The exhaust gas circulatory system used in the Scania Euro 4 standard engine is water-cooled. In the Euro 5 standard product, in order to achieve a higher exhaust gas cooling performance of the product, we have adopted a two-phase cooling design, ie cooling. An air cooler was added to the front of the unit to achieve this performance. This is Scania's unique design," explains Hofstedt. "The key to mixing the intake and exhaust gases is the variable area turbocharger. Like other engine parts, it is controlled by the engine management system, which is another of our independent R&D achievements."
Collaboration with Cummins in the field of Ultra High Pressure Fuel Injection System (XPI)
Scania's ultra-high pressure fuel injection system XPI, as a new generation common rail fuel injection system, welcomes the dawn of hope for combustion control technology. This technology was developed by Scania and Cummins, a professional engine manufacturer headquartered in Indiana, USA. At present, both parties have established a joint production base. The two companies have long-term strategic alliances and have always maintained a cooperative relationship in fuel system development since the early 1990s. In 2001, the two parties jointly launched the joint research and development of the Scania High Pressure Injection System (HPI).
Jonas Hofstedt, head of Scania Power Systems R&D, praised: “The cooperation has been going very smoothly and the two companies have benefited from professional exchanges and the development of fuel injection and combustion technology.â€
Compared with the same type of engine system, Scania ultra-high pressure fuel injection system XPI achieves higher injection pressure, offering more options in terms of timing and injection pressure. The injection system is currently in production in Mexico and is expected to be put into production in 2009 at the new Scania plant in Södertälje, Sodertalje, Sweden.
Paco Lopez, the only driver on-site testing for the "Columbus" truck, has a personal experience of the revolutionary subversion of Scania's ultra-high pressure fuel injection system in the new Euro 5 standard. He predicted, "This will undoubtedly have a huge impact on the engine market."
Scania continues to update and improve the Euro 5 engine using the new system for ultra-high pressure common rail fuel injection. Before the project started, the on-site test mileage of the new engine has reached 2.5 million kilometers.
Lopez is confident in the new engine equipped with Scania's ultra-high pressure fuel injection system. He said, "I think the new engine will have great success. I like this engine very much. After the field test is over, I will recommend my boss to buy the truck equipped with this engine. Now I am looking forward to it. My wish can come true.
