Emissions Solutions for 2007 and 2010 Heavy-Duty Diesel Engines

The today main challenge to protect the environment through the development of new and more efficient transportation systems is presented. The absolutely necessary goods distribution and human transfers are polluting and damaging the environment and new solution should be envisaged; the conflicting strategies to adopt new types of environment friendly transportation while maintaining operative the more economically convenient, but largely polluting, already existing machines are discussed and compared. Shipment is an activity that is occurring since the existence of man who felt the need to find ways for him and his goods transportation. Physical human body limits have led to the discovery of a variety of systems for a continuous transportation evolution. This work analyzes the new environment friendly technologies that have been recently developed or that could be further implemented in the next near future. In view of the constantly improvement of the quality of transportation to be carried out, the transportation sector has various aspects that need to be investigated. Passenger comfort, flexible design, maximum interior space, safety and greater range are main features that improve transportation efficiency while making these technologies more familiar and accepted by consumers. Avoiding any excessive generalization, the three major transportation interacting branches, namely, infrastructures, vehicles and management have been reviewed. Such a complex system needed the application of an evolutionary design approach considering renewable energy sources for Hydrogen production as well as electric or internal combustion engines. The overall transportation network and related terminals have been involved as infrastructures, while all aspects of design, construction, operation diagnostics and traffic interactions have been considered for the vehicles. Finally, the management of the engineering responsibilities chain to ensure quality, safety and environmental impact of the transportation systems has been assessed.

Abstract:Internal combustion engines in line (regardless of whether the work in four-stroke engines and two-stroke engines Otto cycle engines, diesel and Lenoir) are, in general, the most used. Their problem of balancing is extremely important for their operation is correct. There are two possible types of balancing: Static and dynamic balance. The total static to make sure that the sum of the forces of inertia of a mechanism to be zero. There are also a static balance partial. Dynamic balance means to cancel all the moments (load) inertia of the mechanism. A way of the design of an engine in a straight line is that the difference between the crank 180 [°] or 120 [°]. A different type of construction of the engine is the engine with the cylinders in the opposite line, called "cylinder sportsmen". In this type of engine (regardless of their position, which is most often vertical) for engines with two cylinders, one has a static balance total and an imbalance in the dynamic. Similar to the model of the earth concentrated in rotation movement are resolved and load balancing shafts rotating parts. An important way to reduce losses of heat engines is how to achieve a better balance. The methods may be used in equal measure and on engines with external combustion, type Stirling or Watt.

“…To meet this challenge, it is necessary to save energy, to use more efficient devices and to use carbon-free (renewable and nuclear) energy sources on a large scale (Cauvin, 1994;Dupuy, 1991;Feldman, 2008;Gallez et al, 1997;Genre-Grandpierre, 2000;2007;Gutiérrez et al, 1998;Leet et al, 2004;Madre and Maffre, 1997;Mahalingam and Ramesh, 2013;Naima and Liazid, 2013).…”

The shipments were absolutely necessary at all times, but still have polluted and damaged the environment. The technique of transport or the engineering of transport is the application of the principles of technology and scientific findings to the planning, design check, operation and plan management for any mode of transport, in order to ensure that the conditions of safety, efficiency, quick, comfortable and convenient, economic and environmentally compatible movement of persons and goods (transport). It is a sub-discipline for civil engineering. The importance of the transport engineering in the framework of the profession of civil engineering can be evaluated by the number of divisions of the American Society of Civil Engineers (ASCE), which are directly related to the transport. There are six such divisions (Aerospace; Air Transport, motorways, pipes, watercourses, port, of coastal and ocean and urban transport), which represents one third of the total 18 technical divisions of the ASCE (1987). Humanity is struggling between technological tests of deployment of new types of mild transport for the environment and the need to maintain still in the operation the machines already polluting products in large quantity, cheaper, more convenient economically, that customers have already been accustomed. Transport is at the heart of major cross-cutting issues that are inseparable from issues related to the development and sustainable management of the mobility of goods and people. The automotive sector must meet several challenges to reduce the emission of particulate and gaseous pollutants while limiting the increase in the cost of vehicles. The development of "clean" or "sustainable" vehicles requires the integration of innovative technologies to meet all these requirements. Those all problems need to be addressed by the discipline named Transportation (Transport) Engineering, in view of the constantly improving the quality of transport carried out.
