Development of New V6 3.0 L Turbocharged and 3.5 L Naturally Aspirated Gasoline Direct Injection Engines

SAE technical papers on CD-ROM/SAE technical paper series (2023)

<div class="section abstract"><div class="htmlview paragraph">With the objective of further enhancing the engine performance of the Acura brand and the environmental performance of the Honda brand in relation to the North American market, where there is a need for powertrains with driving force margin for SUVs and pickup trucks, Honda has developed a 3.0 L turbocharged engine and a 3.5 L naturally aspirated engine. Both engines adopt the same newly developed valvetrain structure and share main engine geometries.</div><div class="htmlview paragraph">These newly developed engines are equipped with a compact new valvetrain structure combining Hydraulic Lash Adjusters and roller rocker arms with a valve-lifter based Variable Cylinder Management system which has an internalized switching mechanism. This newly developed valvetrain made it possible to incorporate dual overhead cam structure without enlarging the cylinder head shape relative to the single overhead cam structure. It further achieves this while permitting application of a Variable Cylinder Management system and of a Variable Timing Control for intake and exhaust valves to this engine.</div><div class="htmlview paragraph">Sharing the main engine geometries and components for each type of engine, primarily the new valvetrain structure, also facilitated changes in reciprocating and other parts, and minor changes such as the mounting of a turbocharger and increases in fuel injection system pressure, enabling the required enhancements in engine and environmental performance to be achieved.</div><div class="htmlview paragraph">Regarding the turbocharged engine, the twin-scroll type turbocharger combined with the V6 engine made it possible to increase power and enhance boost pressure responsivity while preventing enlargement even over the single turbocharger. That turbocharged engine achieves maximum power of 265 kW and maximum torque at 1400 rpm of 480 Nm, raising the figures for the existing engine by 26.7% for power, and 35.2% for torque.</div><div class="htmlview paragraph">Regarding the natural aspiration engine, the high fuel pressure system and the multi-stage injections made it possible to reduce emissions by reducing fuel adhesion in the cylinders and enhancing homogeneity. It further enables enhancement of the thermal efficiency by combining dual Variable Timing Control and high-tumble ports and piston crown shape designed to maintain tumble flow. That natural aspiration engine achieves a maximum power of 213 kW and a maximum torque of 355 Nm. In terms of environmental performance, the thermal efficiency is 37.5%, an increase over the 36.5% of the existing engine. A vehicle equipped with this engine was also able to achieve LEV III and SULEV30 standards as well as particulate matter (PM) of 1 mg/mile.</div></div>

Formation of the Vertical Slits in the Lower Part of a Sintering Bed and Their Effect on Sintering

Tetsu-to-Hagane (1997)

Kouichi Nushiro Yukio Konishi Katsutoshi Igawa Kenji Takihira Norifumi Fujii

The conditions for stable formation of vertical slits in the lower part of the sintering bed and their effect on the sintering were investigated. The effect of the slits was evaluated experimentally with a test pot, feeding simulator and commercial plant. The total pressure drop was decreased and the permeability in the bed was improved by the formation of vertical slits. The gas flow rate in the slits was calculated at 1.8 times as large as that of a conventional bed. Moisture condensation, which decreases the void fraction in the sintering bed, is reduced by this increased gas flow rate. To form slits, plates were inserted vertically in the lower part of the raw material on the pallet of sintering machine. The ratio of the height of the plates to the distance between plates should be under 0.5 for stable feeding without stagnation of the raw material.

New methods of burden distribution control in bell-armour charging.

Transactions of the Iron and Steel Institute of Japan (1984)

Tomio Haru Mitsuo Saino Motozo YASUNO Kazuo Okumura Kenichi Kaneko

Under the present situation which is forced to reduce the productivity of the all coke operation, it is important to establish such a distribution adjusting technique as to maintain an adequate peripheral gas flow and a sharp central gas flow simultaneously. The gas distribution in a furnace equipped with a bell-armour in comparison with that of the bell-less top has a tendency to flatten owing to the difference in size segregation behaviour in the radial direction, thus posing a problem in micro-control of the burden distribution.The authors have recently developed a new technique of controlling the burden distribution by the movable armour and applied it to Chiba No. 5 Blast Furnace. The technique is aimed at improving the layer thickness and promoting the particle size segregation in the radial direction, slowing down the raw material discharging rate from the bell by controlling the bell stroke and speed.By the application of this technique, it has made possible to strengthen both the peripheral gas flow and central gas flow simultaneously, and thus has greatly contributed to stabilizing the furnace condition and extention of the permitted limit for operation under the recent circumstances of reduced production.
