The Type 1120 Station Keeping Buoy is designed to provide a cost-effective alternative to traditional, moored, ocean buoys. The Station Keeping Buoy is capable of being deployed from a location near shore, travelling to a pre- determined data collection site, and remaining at that site without the need for a mooring. When data collection needs change or when on-board experiments must be changed, the Station Keeping Buoy can be recalled to the deployment site. All of this can be accomplished without the need for an ocean-going vessel to carry the buoy to the data collection site, install moorings, or provide on-site service.
In high‐power self‐propelled vehicles, it may be useful to divide the generation power into multiple modules to start only the necessary diesel engines that work with higher utilization factors and thus higher efficiency. In services that include electrified and nonelectrified lines, it may be useful to have trains capable of running purely electrically, taking energy from the contact line, or like the railcar, powered by a diesel engine. This solution allows for greater efficiency and reduced environmental impact, especially in urban contexts. Increasing fuel prices and stricter exhaust and noise emission regulations pose a challenge for railway operators that rely on diesel propulsion, so they are directing their attention toward alternative propulsion systems for the future. A solution that caught the attention of train manufacturers is represented by the replacement of the diesel engine with a fuel cell generator. A diagram illustrating the basic structure for a fuel cell railway vehicle is presented.
Diesel exhaust emissions legislation is driving acceptable NOx emissions to ever lower levels. To continually meet the challenges presented by this trend, new SCR controls technologies must be considered as well as new ways to sense and control them. Ammonia storage controls technology was developed to manage ammonia utilization within a Selective Catalytic Reduction (SCR) sub-system and thereby facilitate the effective and efficient reduction of nitrogen oxides (NOx) in Diesel engine exhaust streams while at the same time improving urea usage and minimizing ammonia slip from the tailpipe. This technology was tested on a medium duty diesel engine using standard test and measurement procedure for engine certification by EPA.
Electric governors are widely used in diesel engine applications. And a proportional, integral and derivative(PED) controllers runs the electric governor in order to control the engine speed. However, it is difficult to analyze the system stability due to the non-linear characteristics of the diesel engine, and as a result, the PID controller should be tuned by trial- and-error approach. In this paper, a locally linearized diesel engine model is proposed based on the experimentally obtained engine torque map, and the proposed model is verified by simulations and experiments. Through the simulations and experiments it is concluded that the proposed model can be used in the system analysis and so to determine the PID controller gains.
In this paper, we present a supervisory control strategy for a hybrid electric vehicle which best exploits the NO/sub x/ characteristics of such a mixed- combustion mode engine, while optimizing fuel economy and meeting driver's demand. This strategy is an extension of our adaptive equivalent consumption minimization strategy (A-ECMS) control strategy, suitably modified to explicitly minimize NO/sub x/ emissions. The HEV configuration, coupled to this control strategy, allows to very effectively manipulate the operating points of the engine to be primarily constrained in the HCCI regime, with very low NO/sub x/ emissions. This results in dramatically reduced NO/sub x/ emissions during actual driving conditions, while retaining the high fuel economy of CIDI engines and hybrids and maintaining the performance envelop of the vehicle. In summary, the control strategy automatically exploits the relatively small region of HCCI operation to minimize NO/sub x/ emissions.
The middle speed four stroke diesel engine has the advantages of small capacity, light in weight, capable to combustion poor fuel oil. In recent years, they have been used more comprehensive than before. Daihatsu 6PSHdM-26H diesel engine, which is a type of 4-stroke medium-speed turbocharged marine diesel engine, is widely used in ocean-going ships. Describes the failure or fuel injection system with low-grade heavy oil led to increased delayed combustion and exhaust temperature will affect the flow characteristics through the engine, changes in diesel engine with turbocharger and running line is the surge caused by an important reason. Considering its working principle and structural properties, this paper establishes its physical and mathematical models in order to set up the numerical calculation method, gets the relative parameters of increased delayed combustion. On the basis of the numerical calculation of air cooler, these results not only provides some theory support to solve deteriorated of operational performance for heavy-duty 4-stroke marine diesel engine, but also decrease the dependence degree for a marine engineer, then make it possible to scientific manage modern big-scale automatic engine room and improve the reliability of marine trust power plant.
A direct coal-fired turbine is a very light engine for powering ships. Weight savings over a diesel engine nearly make up for the added weight associated with fuel bunkering when converting from oil to coal-firing. A method of hot- gas-particulate cleanup based on fragmentation using pulsed CO, lasers is discussed as a means of providing adequate turbine blade life- time. Two cases, a cargo ship and large merchant tanker are considered. Present value of fuel savings equates to the value of a coal- fired turbine For a ten-year lifetime, the value of the turbine due to fuel-lost savings is projected to be roughly 48 M$ for the cargo ship and 194 M$ for the tanker.
In order to reduce emissions and improve performance of internal combustion engines, it is desirable to know the oxygen concentration of the gas inducted into the engine so that the appropriate amount of fuel can be injected. This is especially true for diesel engines in which up to 50% of the exhaust gas is recirculated back into the engine. This work presents an estimation algorithm for the oxygen concentration in the intake manifold of a turbocharged diesel engine. The only quantities needed for the estimation scheme are boost pressure, fueling rate, engine speed and EGR valve lift, all of which are generally known to the engine control unit. This estimator is a first order linear dynamic model (with time varying coefficients) and asymptotically stable. Due to the unobservability of the oxygen concentration model, the speed of convergence of the estimation scheme is fixed by engine parameters, but is as fast as the phenomenon of mixing of the exhaust gas recirculated with the air in the intake manifold. Simulation studies show the effectiveness of the proposed estimator.
In order to further study the grinding mechanism and to improve the grinding quality of non-circular cams a mathematical heat transfer model for cam grinding was set up based on the heat transfer theory with reasonable assumptions and simplifications on a heavy duty cam grinding. Internal distributions of temperature, stress, and deformation of the cam were achieved from the cam grinding simulation by ANSYS with calculation and analysis on instantaneous thermal transfer. Results from the simulation truly reflected the heat distribution in the cam grinding. Supported by experiments, the temperature fields from ANSYS were matched by large by what from on line infra red cameras, with an average relative difference about 8.83%. This offers help in solving the problem of cam surface thermal damage and deformation and others during cam grinding.
