Overcoming the challenges of HCCI COMBUSTION

Homogenous-charge compression ignition (HCCI) holds considerable promise to unlock new IC-engine efficiencies. But HCCI's advantages bring engineering obstacles, particularly emissions control.

The internal-combustion (IC) engine, as a prime mover in the industrial, power and transportation sectors, has simplified the lifestyle of humans. It has revolutionized the automotive sector and the subsequent exponential growth of the automotive population helped create wealth-but also caused pollution- related issues.

The environmental impact of harmful tailpipe emissions and ever-tightening emission regulations is enticing researchers and auto manufacturers to develop engines that would significantly reduce emissions- without a performance compromise. Over the years, researchers have tackled these issues by adopting alternative fuels, advanced aftertreatment devices or modifications in engine design.
