For clarification only, a Lanova cell is a precombustion chamber were both glow plug and fuel injector are placed in a big world diesel engine, it was invented by Recardo research of england back in the 20's and refered to as a swirl chamber.
Bob, refresh you knowledge...
The diesel engine with Lanova cell:
The fuel spray, if injected through the injector with a small spray angle toward the mouth of the cell, does not produce much mixture in the main combustion chamber before ignition, which burns slowly until the outflow of hot gases from the cell has improved the mixture formation to such a degree that quicker combustion becomes possible. These processes contribute toward a slow pressure rise in the early stage of combustion and high thermal efficiency.
Also the Lanova cell are a air camber.
The Lanova cell is a development of Franz Lang who in the early days of the Diesel engine was associated with Dr. Rudolph Diesel.
The diesel engine with "swirl camber":
The swirl chambers developed by Sir Harry Ricardo, using a two-piece spherical chamber with a narrow "throat" to induce turbulence and has a injector and glowplug in the swirl camber.
