Recently, Scania of Sweden held a media conference in the Stockholm archipelago to launch its new V8 marine engine. The new V8 engine uses XPI high-pressure fuel injection technology with a maximum power of 1,150 hp, making it one of Scania's most powerful engines.
Scania's new V8 marine engine delivers up to 1,150 horsepower to the work boat. Not only that, but the new generation of engines not only has improved power, but the entire power plant takes up less space during installation, so it is easier to upgrade the engine. At the same time, the introduction of XPI fuel injection technology can save economic costs, and the cost is reduced by 5% compared with the previous generation V8.
Scania's new V8 marine engine is equipped with improved XPI fuel injection technology for unparalleled fuel efficiency.
As a proven technology of Scania, XPI fuel injection systems are widely used in Scania's truck and industrial engines.
Svante Lejon is a Senior Technical Consultant in Scania's R&D department, developing technical performance concepts for industrial and marine engines. He said: "The XPI system injects more fuel into the cylinders in a short period of time, providing more power. However, this puts higher demands on the filtration system and fuel cleaning because the system is more sensitive to solid particles. â€
Lejon said: "Before Scania did not use common rail technology in the ship program, this is the challenge we face. The ship's fuel quality requirements are different from truck and industrial applications, but the filtration technology has reached a very high level. Performance can meet Scania's requirements."
It is reported that the introduction of the XPI system will help to save economic costs, compared with the previous generation V8, the new V8 marine engine use cost reduced by 5%.
The Scania V8 marine engine is a proven engine and the most powerful of the Scania marine engines. With a maximum output of 1,150 hp (846 kW), this engine is suitable for use in marine propellers and waterjets.
The new V8 engine has an output range of 900-1150 hp (662-846 kW) depending on the application and speed.
Although the new engine power has improved compared to the previous generation, in fact, the size of the complete installation has become smaller, and it is easy to upgrade the existing V8 engine.
At the same time, Scania's modular system, combined with its engine management system (EMS), can be applied to the same engine platform in different ranges, so the engine solution can be tailored to completely different operating methods. These internal solutions from Scania guarantee a high degree of availability and applicability.
Lejon said: "With the Scania engine management system, we can optimize the engine platform. If not, we can't use our engine in many fields.
Scania's marine engine solutions currently include 9-, 13-, and 16-liter engines for auxiliary power and propulsion systems. These engines have been certified for pollution emissions such as IMO Tier II, EU Stage IIIA, US Tier 2, US Tier 3, US IMO, CCNR II.
In 2015, Scania's global service network has added 30 new service points. Up to now, there are more than 1,800 service points around the world, which can provide more perfect and convenient services for marine engines adopting new XPI technology around the world.
Since 2007, Scania has introduced the common rail XPI fuel injection technology for the first time in the field of truck engines, and has since started to use it in industrial engines. This fuel injection system is part of the Scania modular system. Similarly, the new V8 marine engine can also share components with other engines such as cylinder heads, valves, pistons and fuel injectors.
Therefore, regardless of the use of the Scania solution anywhere in the world, the company's service outlets will support shipowners and ship operators in the vicinity. These more than 1,800 service outlets have nearly 10 years of experience in service and maintenance of XPI engine solutions. Stephan Pettersson, President of Scania Engine Market Development and Support, said: "As long as you know a Scania engine, you know all Scania engines." In other words, Scania's most powerful marine engine can also enjoy Scania's perfect service.
Brazed Plate Heat Exchanger
The brazed Plate Heat Exchanger (BPHE) is a type of heat exchanger construction in which metal plates with flat surface offer an effective and efficient method of heat transfer. These plates are joined together by brazing (mainly copper), typically stainless steel. Due to the close contact between the two surfaces, there is a very high heat transfer coefficient, leading to a low overall unit size. They therefore provide much greater efficiency than a Shell And Tube Heat Exchanger.
Brazed Plate Heat Exchangers are widely used in air-conditioning and refrigeration, power generation, and other process applications. For example, within a cooling cycle, a BPHE can be used to transfer heat from one fluid to another. Typical fluids in such coils and systems are either glycol or water. In a power system, a BPHE can be used to cool oils, recirculating lubricants, fuels, and other fluids.
The major advantages of BPHE are their compact size, efficient heat transfer and minimal pressure loss. BPHEs also have low maintenance requirements and a long service lifetime. Furthermore, because of their flat surface design, BPHEs have no patterns or turns and thus lower energy costs and minimize fouling. Finally, the material used in BPHEs makes them resist to corrosion and heat, making them ideal for high temperature and hostile environments.
