Another 6-Stroke Engine
 ✖  |
Roger Bajulaz from Switzerland took a different tack to the challenge nearly 20 years ago and continues to refine it today. His company, Bajulaz S. A., patented a 6-stroke engine that uses heated air in a cylinder head modified with a combustion chamber inside an air chamber. Heated air from the cylinder charges a combustion chamber as fuel is injected. After ignition, the high pressure is released into the cylinder for an expansion stroke. The heat released at ignition heats the air in the surrounding air chamber, pressurizing it for release to power an additional stroke.
Bajulaz claims thermal efficiency of 50 percent versus 30 percent for traditional internal combustion engines, 40 percent reduced fuel use, direct injection and optimal fuel combustion at every engine speed. Plus, the company claims almost any type of petroleum or vegetable oil, even animal grease, can be used in the system. This could reduce emissions by 60 to 90 percent.
Aside from the head, Bajulaz claims no significant modification would be needed to a standard engine design. Like Crower's engine, the cooling system is reduced. Bajulaz S. A. projects that were a company to adopt the design, cars with it could be on the market within three to five years.
