Flash evaporation technique inspired from bombardier beetle was investigated for diesel fuel injection system to improve the burning efficiency. The effect of flash evaporation on spray cone angle and spray penetration was investigated for two injection pressures with pintle type injector. Both the parameters were measured using a camera at a speed of 120 frames per second. The results of our pilot study suggest that wider cone angle and moderate penetration can be achieved even at low injection pressures which will eventually help to improve the combustion process and fuel efficiency and reduces carbon emission.
