For the high-power low-speed diesel engine’s performance and reliability evaluation, this paper studies the engine’s running-in norms, presents the Test Scheme about the combustion process, the Inlet swirl control, the cooling system control, and the distribution and emission. The whole engine’s test methods and systems are established. By using the combined method of the test platform research...

Borderline spaces of Besov type consist of tempered distributions satisfying the property that the partial sums of their B ∞,1-norm diverge in a controlled way. We prove an existence and uniqueness result for the three-dimensional axisymmetric Euler equations without swirl when initial vorticity belongs to these spaces. We also prove that for this class of solutions the vanishing viscosity limi...
