    • The invention relates to a method and an arrangement for determining a fuel quality of a fuel for a combustion engine (10), particularly for a diesel engine, wherein the fuel is conveyed from a low pressure fuel tank (12) to a high-pressure volume (22a, 30), and injected into at least one cylinder (18) of the combustion engine (10), wherein a control valve (24) is provided for controlling directly or indirectly the amount of fuel injected into the at least one cylinder (18). An actual value (S_24) of a timing signal of the control valve (24) is compared to a reference value (S_ref) of the timing signal of the control valve (24) and a fuel quality parameter is derived from a difference (ΔS) between the actual value (S_24) and the reference value (S_ref) of the timing signal of the control valve (24) and/or that a fuel quality parameter is derived from a gradient of the pressure increase during a build-up phase of the pressure (p_inj) in the high-pressure volume (22a) compared to a reference value (p_ref) of the gradient of the pressure increase in the high-pressure volume (22a).
    • 本发明涉及一种用于确定用于内燃机(10),特别是用于柴油发动机的燃料的燃料质量的方法和装置,其中燃料从低压燃料箱(12)输送到高压 (22a,30),并且喷射到所述内燃机(10)的至少一个气缸(18)中,其中设置有控制阀(24),用于直接或间接地控制喷射到所述至少一个气缸 (18)。 将控制阀(24)的定时信号的实际值(S_24)与控制阀(24)的定时信号的基准值(S_ref)进行比较,并且从差值(&Dgr; (S_24)和控制阀(24)的定时信号的参考值(S_ref)之间和/或燃料质量参数是从积聚阶段的压力增加的梯度导出的 与高压容积(22a)中的压力增加的梯度的参考值(p_ref)相比,高压容积(22a)中的压力(p_inj)。
