The design limits the loss of energy as heat by a variety of technologies; using lube oil as coolant too, no water cooling of the engine block is required, though an oil cooler is needed. It had a 25% fuel efficiency advantage over contemporary designs in the 1980s. Several revolutionary improvements were achieved in this design, such as a new piston design and combustion process.
The technology was adopted by some companies in the former Soviet Union and a major project by Grupo Garavello, which went bankrupt by their other business activities, was undertaken in Brazil
