Mazda continues to win awards for developing fuel-saving, environmentally-friendly technologies for its customers. Two Mazda engineers were presented with the Outstanding Technical Paper award at the 61st annual Society of Automotive Engineers of Japan (JSAE) presentation. Takashi Youso and Masahisa Yamakawa, both from Mazda's Powertrain Development Division, were honoured for their research paper entitled A Study on the Relationship between Fuel Characteristics and Auto-ignition in Gasoline HCCI Engines.Mazda has over 90 years of ground-breaking engineering expertise, and this year's honour brings to 11 the JASE awards Mazda has won just since 2006. Last year, for instance, Mazda took home three awards for research that will be used in Mazda's next-generation SKYACTIV vehicles - Mazda's unique start-stop system, i-stop, its single-nano technology catalyst, and for groundbreaking research into the properties of sound insulation material.This year's winners are honoured for analyzing the effects of different fuel components on ignition performance of an engine using homogeneous charge compression ignition (HCCI). The paper predicts auto-ignition timing for various grades of petrol from markets around the world, and also demonstrates how knock can be avoided when using a standard spark ignition system as well. The analysis was used to develop Mazda's SKYACTIV-G engine which will employ the highest compression ratio (14.0:1) ever achieved in a petrol engine, while drastically lowering fuel consumption and emissions.
