内燃机控制设备
摘要：
公开了一种内燃机控制设备，其包括用于检测缸内压力Pc的缸内压力传感器。燃烧开始时刻θ0和燃烧结束时刻θf是用作内燃机的控制指标的参数，根据点火正时SA来判定燃烧开始时刻θ0和燃烧结束时刻θf(步骤102)。根据由缸内传感器在两个点测量的缸内压力Pc获取关于放热量PVκ的信息(步骤104)。根据方程3估算缸内压力Pθ，方程3定义了放热量信息、控制指标参数和缸内压力Pθ之间的关系(步骤106)。
摘要（英）：

Disclosed is an internal combustion engine control apparatus that includes an in-cylinder pressure sensor for detecting in-cylinder pressure Pc. Combustion start time Theta0 and combustion end time Thetaf, which are parameters serving as control indexes for an internal combustion engine, are determined in accordance with ignition timing SA (step 102). The information about a heat release amount PV is acquired in accordance with the in-cylinder pressures Pc that are measured at two points by the in-cylinder pressure sensor (step 104). The in-cylinder pressure PTheta is estimated in accordance with Equation 3, which defines the relationship among the heat release amount information, control index parameters, and in-cylinder pressure PTheta (step 106).
