Engine Oil Development
The objective of this work package was to develop suitable engine oil for vegetable oil fuelled engines and provide sufficient quantities for the demonstration fleet in WP5. The engine oil was successively developed and tested in the tractors of different emission stages at John Deere before being made available for the demonstration fleet.
The target oil drain interval for tractors running on vegetable fuelled engines was 500 hours, which was demonstrated in the engine demonstration workpackage. Intermediate targets were the demonstration of oil suitability at the stages of the engine test development process.
Oil suitability was measured via analysis of the chemical and physical properties of the oil drain samples. Oil suitability was demonstrated via the discussion of the oil drain analyses with the other WP members (specifically John Deere).
