Diesel
The diesel car has been recognized as the main culprit of air pollution, but people are beginning to understand the diesel car in a different way. The clean diesel engine has a mechanism of compressed air and blast, and it enables the engine to generate the same power as gasoline engine with 30-40% less fuel. It is recognized as an environmentally-friendly car in Europe and is even bein

HCCI is Homogeneous Charge Compression Ignition
HCCI engine concept combines aspects of SI and Diesel engines by compression igniting a pre-mixture of fuel and air.
No flame propagation or mixing controlled combustion – global auto-ignition of the charge .
Can use uniformly ultra-lean mixtures, giving low peak combustion temperatures, near zero NOx emissions.

The State of the World's Health / 세계의 건강 상태
Individuals regularly make decisions about their physical and mental health. They do this partly because a serious illness can have a devastating effect on a person and on his or her family. Similarly, just as the health of a family is connected to individuals within that family, the health of a nation is clearly connected to the
