The line pressure at injector side and nozzle needle lift were measured to evaluate the injection process of different mixing ratios of a bio-diesel.The measured results show that the peak pressure is higher,the injection delay and duration exhibit a slightly longer,which made a higher fuel-injection per-cylinder cycle,at the same fuel delivery advance angle,engine speed and load,when the bio-diesel ratio increases.
