The Elsbett engine is an 89 HP, direct-injection diesel engine designed to run on straight vegetable oil. The engine is also known as Elko engine (for "Elsbett Konstruktion") and was invented by Ludwig Elsbett.
The design limits the loss of energy as heat by a variety of technologies;
- the fuel charged is injected in such a manner as to 'blend perfectly with the air' and combust within a central core of hot air, not contacting the chamber walls, which is necessary for good air/fuel with other designs examined. The Elsbett engine has a deep bowl which has a slight lip
- the engine also doesn't use any water cooling. Instead, only oil is used as a coolant fluid. No water cooling of the engine block was required, and only an oil cooler was used to cool down the oil circulating.
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 Garavelo, one of the 50th largest corporations in Brazil in the 80s,Pres. Luiz Garavelo, VP Marco Garavelo and MKT Dir Julio Garavelo, with the Consorcio Nacional Garavelo (140 sales points and 280.000 clients, Banco Garavelo, Hunday-Garavelo, gave vieculos, Lagpar, Mag, Fazenda Nova Viena, Garavelo Agropecuaria, Garavelo Oleos, Garavelo Publicidade, Lojas Garavelo, Garavelo Agropecuaria, Grafica Garavelo, Coryntho Corretora de Seguros, Garavelo Imobiliaria and others, was undertaken in Brazil. Although work continues on the dedicated multi-fuel Elsbett engine, the company now also sells conversion kits for existing diesel engines to run on vegetable oil.
