Abstract
A tutorial write up is first presented to give the behavior of droplet burning (diesel engines) and natural gas burning for dual fuel and natural gas burning engines. By citing literature, it is shown that for each droplet there is a certain amount of generated. The combination of droplet burning (in the prechamber) and with natural gas in the main chamber with a good turbocharger system Danyluk, Ref. 1, has shown that NOx can be controlled to 1.0 gram per brake-horsepower hour while maintaining high brake thermal efficiency. This author has generalized the information in die design of PCCI (Prechamber Compression Ignition) engine systems. A design chart is given to size the prechamber.
