Nesta investigação, o biodiesel é produzido a partir do óleo de sementes de Xanthium strumarium L., vulgarmente conhecido como berbigão, e o ácido linoleico é também separado do mesmo. Estes são utilizados para tentar aumentar o valor calorÃfico do biodiesel de óleo de karanja. O biodiesel de berbigão também é misturado com gasóleo para encontrar a adequação com o hardware da máquina e para encontrar as melhores variáveis de entrada, também é feita uma tentativa de reduzir as emissões de NOx utilizando EGR e injeção retardada. Durante esta investigação, verificou-se que há um aumento do valor calorÃfico do biodiesel de óleo de karanja com a adição de biodiesel de carqueja e de ácido linoleico, mas o aumento do HCV é maior com a adição de biodiesel de carqueja do que com a adição de ácido linoleico. Verifica-se também que o aumento do BTE do biodiesel de óleo de karanja é maior devido à adição de biodiesel de berbigão do que de ácido linoleico na mesma quantidade nas melhores condições de funcionamento do motor. Verificou-se que há uma diminuição do consumo de combustÃvel em comparação com o biodiesel de óleo de karanja para a mesma potência. Observou-se que a adição de biodiesel de carqueja reduz as emissões de NOx dos motores diesel em comparação com o diesel e o biodiesel de karanja sem afetar o desempenho do motor.
