A high-strength aluminum cylinder block manufactured using a new production process, ASCT (Advanced Semisolid Casting Technology) has been adopted for the newly developed 2.2L 4-cylinder i-CTDi (Intelligent Common rail Turbo Diesel Injection) diesel engine fitted in the new Accord to be marketed in Europe. In the production process, a semisolid aluminum is used during high-pressure die-casting. In addition, newly developed pressure resistant sand cores are used to mold the closed deck. Heat treatment is conducted to ensure a high level of materials strength. To respond to the high load on the crankshaft journal, die-cast aluminum lower block with cast iron bearing caps inserts are employed. Adopting the dummy head honing to reduce bore deformation and offset cylinders have enabled the achievement a lightweight and compact cylinder configuration matched to the high combustion pressure of the latest diesel engines, while maintaining a high level of quietness.

The influence of ultrasonic vibration on the freezing temperature of hydrate, disodium hydrogenphosphate 12-water, is investigated for the purpose of the application to long-term thermal energy storage. Four different frequencies and different sound power are tested to the super-cooled material. Experimental results show that the freezing temperature of the hydrate is independent of the cooling rate, and any meaningful change of the freezing temperature is not observed under the ultrasonic vibration. Like other researches on distilled water, the freezing temperature of the hydrate tends to be lower as the volume of the sample becomes smaller.
