The start process of multi-cylinder diesel engine has been experimental investigated in this paper. With a fixed injection duration, the experiment is performed with different timing. Then, timing, starting moment duration. Based on above data and calculation method, matching strategy for transmission system put forward as well corresponding strategy.

<title>Abstract</title> Central heating system is a nolinear with the features of thermal inertia and hysteretic nature, etc. In order to solve temperature control problem heat network uniform heating, this paper designs flow controller using two-degree-of-freedom PID (Proportional-Integral-Derivative) algorithm, which can adjust two parameters external disturbance inhibition property target tracking feature independently respectively best simultaneously so that effects inertia, nature on...

In order to solve the problem that guidance of green growth practice has not reached expected effect due lag evaluation system in previous simulation models, a economy development model based on dynamics is proposed. For purpose developing economy, structure analyzed, and variable relationship determined. According types variables, established. test stage, mining industry Lueyang county selected as research object. The analysis results show CO2 emission gradually decreasing, GDP generally...

A reverse logistics network for municipal solid wastes is designed. fuzzy chance constrained programming model that the uncertain recovery quantity described by parameter put forward. The solved transforming it to a deterministic mix integer linear after making constraints clear. numerical example provided demonstrate feasibility of model. And this paper analyzes influence different confidence level

For the problems of low efficiency and use rate intelligent technology in high-traffic restaurants’ plate recovery process, this study proposes implementation fully automated mechanization using gravity sensing on flipping & tipping, multi-functional recycling machine oil-water separation for slop oil as core function. Throughout cleaning device avoids direct contact with residue, ensuring cleanliness device. In addition, residue is deposited storage barrel without causing secondary...

A curve approximation method based on cellular automata was produced, and applied to digital of hydraulic turbine performance data. The computed results examples indicated that the results, which made by using approach Cellular Automata approximate characteristics, high in calculation precision able reflect characteristics objectively. It could be used control optimized operation.

The load forecast is the foundation of optium control for heating system. This paper systematicaly discussed application research system predication which adopted fuzzy neural networks technology. RBF are constructed by MATLAB. method characterized higher computing accuracy and fast convergence velocity, it very suitable in engineering may greatly enhance automation central energy-saving effects.

The single degree of freedom offshore wind turbine system load model is analyzed and calculated by adopting the linear response power spectrum method. Some results, including vibration velocity spectrum, acceleration shear tower bottom, moment are obtained. Through analysis it found that sheer force bottom not only dependent on aerodynamic wave but also determined natural frequency damping ratio. It does lay directly equivalent mass stiffness. So, can be deduced ratios decisive in design...

A low rank coal was first used to investigate the synergistic effect of inherent and loaded potassium calcium ions on pyrolysis behaviors. The non-isothermal thermal analysis with higher heating rate medium temperature carried out by thermogravimetric analyzer for selected raw treated samples. Preliminary experiments conducted show that particle size smaller than 160 mm can eliminate heat mass transfer effect, most volatile matter released (R-coal) 750?C. Moreover, rate, moisture evaporation...
