摘要： PROBLEM TO BE SOLVED: To provide a process different from a conventional process in a control to suppress the deviations of intake air amounts between cylinders by handling the variations of valve lift amounts and valve timing angles of an intake valve. SOLUTION: For the variations of intake air between cylinders Sd more than a reference value Krg ("YES" in S154), an average intake flow speed at the intake valve is made to be less than 0.85 times the sound speed by setting a valve lift amount VLAx for use in reducing average intake flow speed that is larger than usually set valve lift amount at a target valve lift amount (S156). Thereby, the compensation of the variations of intake air amounts is designed to be made to a certain degree by making shorter the period during which changes in average flow speeds are restricted by the sound speed. Thus, the variations of intake air amounts between cylinders are suppressed, and the selection of the control can be extended. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：通过处理进气门的气门升程量和气门正时角度的变化，提供与控制中的常规方法不同的方法，以抑制气缸之间的进气量的偏差。
解决方案：对于气缸Sd之间的进气的变化比参考值Krg（S154中的“是”），进气门的平均进气流量通过设定小于声速的0.85倍用于减小通常设定目标气门升程量时的气门升程量的平均进气流量的阀升程量VLAx（S156）。因此，通过使平均流速的变化受到声速的限制的期间缩短，能够使进气量的变化的补偿在一定程度上进行。因此，气缸之间的进气量的变化被抑制，并且可以扩大控制的选择。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent a liquid fuel from adhering to an inner wall surface of a combustion chamber in cooling a port injection type internal combustion engine.SOLUTION: In cooling the internal combustion engine for executing an Atkinson cycle, an intake valve opening timing is adjusted to a timing when the occurrence of a reverse flow into an intake port starts (S106-114), so that sudden intake into a cylinder is not caused right after the intake valve is opened. The liquid fuel, which exists in a wall surface of the intake port or a back surface of the intake valve in cooling the internal combustion engine, is evaporated from the surface in the relatively mild airflow and is absorbed into the combustion chamber. As a result, the fuel is not absorbed into the cylinder while it is in a liquid state, which prevents the adhesion of the liquid fuel to the inner wall surface of the fuel chamber. Accordingly, combustion is not locally enriched, and PM generation is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine, capable of estimating a suction gas flow rate with high accuracy even when EGR is used.SOLUTION: When exhaust gas is circulated into an intake pipe 34, gas density ρm in the intake pipe 34 is changed. The gas density ρm is represented by ρm=MPm/RTm (M: molecular weight of gas), and has an inverse relationship with gas temperature Tm in the intake pipe 34. Therefore, when a circulation exhaust gas flow rate is low, the gas temperature in the intake pipe 34 is low, and the gas density in the intake pipe 34 is increased, thereby increasing the amount of suction gas. Meanwhile, when the circulation exhaust gas flow rate is high, the gas temperature in the intake pipe 34 is high, and the gas density in the suction pipe 34 is reduced, thereby reducing the amount of suction gas. Accordingly, by correcting the amount of suction gas by a change of the gas density in the suction pipe 34, the amount of suction gas when external EGR is utilized is accurately predicted.
摘要翻译：要解决的问题：提供一种用于内燃机的控制装置，即使在使用EGR时也能够以高精度估计吸入气体流量。解决方案：当废气循环到进气管34中时，进气管34中的气体密度ρm改变。气体密度ρm由ρm= MPm / RTm（M：气体的分子量）表示，与进气管34的气体温度Tm成反比。因此，当循环排气流量低时，气体进气管34中的温度低，并且进气管34中的气体密度增加，从而增加吸入气体的量。同时，当循环排气流量高时，进气管34中的气体温度高，并且吸入管34中的气体密度降低，从而减少吸入气体的量。因此，通过利用吸入管34中的气体密度的变化来校正吸入气体的量，能够准确地预测使用外部EGR时的吸入气体量。版权所有（C）2012，JPO＆INPIT
