29 Mar 1996TL;DR: In this paper, a varying mechanism (VVT) for continuously varying the valve timing of an intake valve in a predetermined range is provided on a cam shaft in an engine, thus adjusting the amount of the internal EGR in combustion chambers.
Abstract: A varying mechanism (VVT) for continuously varying the valve timing of an intake valve in a predetermined range is provided on a cam shaft in an engine. By controlling the VVT, the valve overlap period of the intake valve and an exhaust valve is continuously varied in a predetermined range, thus adjusting the amount of the internal EGR in combustion chambers. When determining that the operational load of the engine is small and intermediate based on the value of a manifold pressure, an electronic control unit (ECU) computes a target value for advancing the valve timing with respect to the rotational phase of a crankshaft based on a throttle angle, an engine speed, etc. The ECU also computes a limit value to restrict the target value in accordance with the value of the manifold pressure. When the target value is smaller than the limit value, the ECU controls the VVT based on the target value. When the target value is greater than the limit value, the ECU replaces the limit value with target value and controls the VVT based on this target value.

TL;DR: In this paper, the results of first-principles calculations on the structural properties (lattice constants and internal parameters), dielectric properties (macroscopic, static, and Born effective charge tensors), and dynamical properties for the three polytypes of BN: the cubic zinc-blende structure, the wurtzite structure, and the hexagonal structure.
Abstract: We report the results of first-principles calculations on the structural properties (lattice constants and internal parameters), dielectric properties (macroscopic and static dielectric constants, and Born effective charge tensors), and dynamical properties $(\ensuremath{\Gamma}$-phonon frequencies) for the three polytypes of BN: the cubic zinc-blende structure $(c$-BN), the wurtzite structure $(w$-BN), and the hexagonal structure $(h$-BN). Our calculations were performed with the ultrasoft pseudopotential method and the linear response approach based on density-functional perturbation theory. By comparing the cohesive energies, we found that the c-BN structure is the most stable among the three polytypes at zero temperature. The computed equilibrium structural parameters, bulk moduli, and dielectric properties are in good agreement with the experimental data except for the lattice constant c of h-BN and the macroscopic dielectric constant along the c axis of h-BN. The $\ensuremath{\Gamma}$-phonon frequencies of c-BN and w-BN are close to each other. In order to distinguish c-BN and w-BN by Raman spectroscopy, it turns out that we should investigate the two Raman active ${E}_{2}$ modes that exist only in w-BN.
