Technical Articles

Experts on engines and drive systems provide an overview of a range of technical issues.

With the Equipment Health Monitoring function of Callosum, MTU today already meets demands that modern naval forces can expect to face in the future. It makes reliable and plannable long-term missions possible even for vessels with small and frequently changing crews. The automation system utilizes the latest analysis techniques like machine learning to minimize maintenance needs, to increase availability and planning reliability for forces on active missions and to cut life-cycle costs.

When lifecycle costs are considered, high-performing and well-maintained MTU engines outmatch the competition with purpose-built design, unmatched quality and tailored service.

Common rail fuel injection systems require high fuel quality to perform optimally. In a dusty environment such as a mining site, these fuel standards can be difficult or impossible to meet. Over time, particles and contaminants accumulate in the fuel, which can cause premature wear and reduce injector life due to the high pressures in the fuel injection system. To ensure optimal performance in these circumstances, MTU has introduced a new fuel filtration upgrade kit for Series 4000 mining engines. Field-tested for more than three years, it has been shown to significantly extend injector life, which reduces operating costs dramatically. The savings can quickly add up over time, especially for mine operations with large fleets of haul trucks.

Fuel expense for diesel-powered fracking engines represents a significant portion of total operating costs within a typical onshore well stimulation spread. Accordingly, with the increased availability of lower priced and environmentally friendly natural gas, aftermarket installed bi-fuel systems have rapidly intensified the interest of well service operators seeking reduced operating expense through utilization of well-site field gas. Through use of integrated bi-fuel engine technology, MTU is able to meet the specific demands of well servicing in a field installable kit, which retains all internal diesel engine components and ensures safe and reliable operation at original engine performance and emissions specifications.

Over the last few years, the so-called NFPA20 standard has been established for fire pump drive systems in the oil and gas industry. This standard by the US National Fire Protection Association (NFPA) requires a redundant engine controller. The second engine controller must be installed on the engine, be permanently wired and, in the event of a fault on the first controller, must take over the engine control automatically without interruption of the fire pump water jet. MTU now offers its fire pump drive systems in line with this standard.

The performance of an internal combustion engine can be increased by adding turbocharging. A turbocharger compresses the air so that more oxygen flows into the combustion chamber. In this way, more fuel is burned and the power output of the engine increases accordingly. The turbocharger is driven by exhaust gas, which makes turbocharged diesel engines very efficient. MTU develops this key technology for high-performance engines in-house.

With common rail fuel injection, the combustion process can be optimized to achieve low pollutant levels combined with lower fuel consumption. Fuel is injected into the combustion chamber from a common rail under high pressure. The electronic control system ensures that the start of injection, the quantity and time are independent of the engine speed. In 1996, with the Series 4000 engine, MTU was the first manufacturer of large diesel engines to introduce common rail fuel injection as a standard feature.

The brain of a modern engine is the electronic control unit. It monitors and controls all the key functions of the engine and the exhaust aftertreatment system. The control unit also acts as the interface to the vehicle’s automation system. The optimum interplay of the entire drive system is the key to low pollutant emissions, low fuel consumption and high power output over the entire service life. MTU develops and manufactures this key technology in-house.

Nitrogen oxide (NOX) emissions can be reduced using internal engine technology by cooling some of the exhaust gas, which is then redirected back into the charge air. This results in the reduction of the combustion temperature and less nitrogen oxide is produced. This process is known as exhaust gas recirculation (EGR) and is one of the principal methods used to reduce nitrogen oxide emissions from diesel engines. MTU has been developing this important technology and the functions and components associated with it since the beginning of the 1990s. It was first introduced in series production in mid-2011 for Series 4000 Oil and Gas engines in hydro-fracking applications (EPA Tier 4 emissions standard). It was likewise intro - duced in rail engines subject to EU IIIB emissions regulations which came into force in 2012.

A diesel particulate filter (DPF) can remove virtually all the soot particulates (PM) from the exhaust gas emitted from a diesel engine to ensure compliance with very strict emission standards. Regardless of the actual emission limit, diesel particulate filters satisfy the needs of operators who place importance on achieving extremely low soot emissions.

The term Selective Catalytic Reduction (or SCR) is used to describe a chemical reaction in which harmful nitrogen oxides (NOX) in exhaust gas are converted into water (H2O) and nitrogen (N2). In combination with internal engine technologies, such as exhaust gas recirculation (EGR), extremely low nitrogen oxide emissions can be achieved with low fuel consumption.

Blue Vision New Generation is an automation system for propulsion plants in yachts and workboats with MTU Series 2000 or 4000 engines. It is available both in a straightforward, non-classifiable version (Blue Vision Basic New Generation) and in an expanded, classifiable version (Blue Vision Advanced New Generation). In a subsequent expansion stage, Blue Vision Premium New Generation will represent the most extensive version.

Since the beginning of the 1980s, the MTU Series 1163 has been one of the most widely used engines in naval shipping. For compliance with IMO II, an advanced version of the unit without exhaust treatment systems was introduced in mid-2013. This version retains all the decisive engine characteristics of its predecessors that were so important to customers. Which means that reliability, high power density and optimum acceleration capabilities also remain the key features of the Series 1163.

Powerline is a complete concept for the automation of drive systems in diesel-hydraulic and diesel-electric locomotives. its modular structure provides a high level of flexibility and ensures straightforward integration in new-builds as well as in locomotive repowering projects. This article describes how Powerline can be integrated in different types of locomotive and explains the functional principles of the individual components.
