To achieve carbon neutrality by 2050, Mazda has adopted a multi-solution strategy considering the energy situation of each country, and one of these solutions is the promotion of biodiesel engines.
Since 2021, Mazda has been participating in the Super Taikyu Race Series for demonstration of next-generation biodiesel fuel and promoting the reliability and awareness of biodiesel engines through the races.
This paper introduces the racing biodiesel engine that we have developed recently based on the technologies and development processes fostered through mass-production developments. By analyzing severe operating conditions of racing, we set a finite lifespan target, fully utilized the potential of each system and optimally reallocated system functions so that we could maximize the overall performance of the engine.
