    Abstract: A method of determining whether a cylinder (1, 2, 3, 4) in an engine system (90) comprising a plurality of cylinders is ready for injection/ignition, the method comprising: monitoring (122) the in-cylinder pressure of each of the plurality of cylinders within the engine system; determining (124) a pressure related parameter for each cylinder within the engine system; wherein, in the event that the pressure related parameter in a given cylinder exceeds a first threshold, the method further comprises performing a diagnostic test in order to determine whether the given cylinder is ready for injection/ignition.

    Abstract translation: 一种确定包括多个气缸的发动机系统（90）中的气缸（1,2,3）是否准备好用于喷射/点火的方法，所述方法包括：监测（122）每个气缸的缸内压力 的发动机系统内的多个气缸; 确定（124）发动机系统内每个气缸的压力相关参数; 其中，在给定气缸中的压力相关参数超过第一阈值的情况下，该方法还包括执行诊断测试，以便确定给定气缸是否准备好用于注射/点火。

    Abstract: A method of diagnosing faults within an engine system (1), the engine system comprising a plurality of cylinders, the method comprising: monitoring (310) the output signal of one or more in-cylinder pressure sensors (3) within the engine system, each of the one or more in-cylinder pressure sensors being associated with a cylinder within the engine system; determining (312) a pressure related parameter for a given cylinder having an associated in-cylinder pressure sensor; and diagnosing (314) the presence of faults within the engine system on the basis of the pressure related parameter.
