Exhaust emissions and mutagenic effects of diesel fuel, biodiesel and biodiesel blends

- We run three diesel engines (Euro 0, III and IV) using biodiesel blends.
- The influence on the exhaust emissions and mutagenic effects were measured.
- Regulated exhaust emissions change approximately linearly with the blend.
- Blends with 20% biodiesel shows a maximum of mutagenic effects and change nonlinear with the blend.
