2012版必威体育精装版日研发10-15模式通用的hcci发动机（The 2012 edition of the latest development of 10-15 model of general HCCI Engine） HCCI (HCCI) engine has been highly anticipated, known as the ultimate fuel-efficient engine. But until now, HCCI has not yet entered the practical. The reason is that HCCI can achieve the best driving area is too narrow. The Chiba University research team developed the empty pumping in the 10 and 15 modes are likely to achieve HCCI driving, increased fuel efficiency close to the 15% target. The sixty-first Japanese automotive technology award has been published in April 26, 2011. In the 6 paper award, 2 HCCI. Because of high efficiency, NOx (nitrogen oxides) and PM (particulate matter), HCCI is known as the ultimate fuel-efficient engine, has occupied the leading role in the Research Institute of. But rarely hear about the practical news *1. As for the reason, insiders are well aware. It is a narrow range of HCCI combustion can be achieved. A narrow range, usually as a spark ignition engine running time will increase. As a result, the fuel efficiency, exhaust the advantage will not appear. *1: the new diesel engine with high injection pressure, therefore, often in the jet ignition delay ends at. But there are also researchers interpret this as, first, because the mixed fire in, so in general still achieved HCCI. The wrong step will knock HCCI is inhaled mixed gas fuel mixing. The mixture is compressed, the gas once and for all natural fire. Chiba University professor Moriyoshi Taeki HCCI said it was like a controlled detonation. All the mixed gas once ignited, burning speed. And the flame propagation velocity is not restricted, therefore, lean burn limit is far greater than the spark ignition. Because the burning speed, can realize the lean combustion, so the combustion efficiency is good. Moreover, the mixed gas after fully mixed, no place is not prone to hypoxia, PM (particulate matter). Because the combustion temperature without deviation, so it is not ea
