Press Release

HIROSHIMA, Japan-Mazda Motor Corporation announces that five Mazda researchers are to accept a Japan Society of Mechanical Engineers (JSME) Medal for New Technology for 2011. An endowment rite will take place during Meiji Kinenkan building in Tokyo on Friday, Apr 20, 2012.

Awarded for:   Development of gasoline engine (1.3L) with a super-high application ratio and achieving fuel potency of 30km per liter*1


   Mitsuo Hitomi                                  Powertrain Technology Div.

   Takashi Yoso                                  Powertrain Technology Div.

   Kiyotaka Sato                                  Powertrain Technology Div.

   Kunitomo Minamitani                       Powertrain Technology Div.

   Yasushi Nakahara                            Powertrain Technology Div.


Achieving a high application ratio in required gasoline engines has been formidable due to a materialisation of aberrant combustion, widely famous as “knocking”. The SKYACTIV-G 1.3, however, achieves a application ratio of 14.0:1, a top in a world*2 for a mass-produced gasoline vehicle engine. The endowment is in approval of Mazda’s find that a low-temperature burning greeting (in that holds within molecules of fuel mangle and furnish energy) occurs before ignition during high application ratios. This leads to a rebate in knocking and boost in output. The prerogative also praises Mazda’s innovative use of this find in a growth of a vehicles.

Further, a fact that a face-lifted Mazda Demio (known abroad as Mazda2), versed with a SKYACTIV-G gasoline engine, achieves a fuel potency rating of 30km/L*1 but faith on a hybrid complement was famous and rarely praised. This superb feat is interjection to a consummate rebate of automatic friction, improvements to Mazda’s singular waiting stop complement “i-stop“, and precisely tranquil invariably non-static delivery (CVT).

Every year, a Japan Society of Mechanical Engineers awards JSME Medals for a best investigate papers in any margin and for building new technologies or machines. The awards are presented in an bid to inspire investigate activities and a growth of automatic engineering. Other awards presented by a Society embody a JSME Award for Young Engineers and a JSME Education Award. This is a seventh time Mazda employees have perceived a JSME Medal for New Technology. Previous medals were awarded for a “Application of Automotive Rotary Unit,” a “Development of Miller-cycle Engine” and “Development of organic formation modules regulating high-strength plastics with prolonged glass-fiber reinforced polypropylene element and injection frame process” and “Development of rotary engine with side empty pier blueprint for vehicle (RENESIS).”
