摘要： PROBLEM TO BE SOLVED: To provide a gas temperature estimating device for an internal combustion engine, capable of more accurately estimating a temperature at an outlet of gas by considering how much temperature of the gas, which passes through a gas distribution pipe having an inlet and the outlet such as an intake manifold and an exhaust recirculating pipe, changes between at the inlet and at the outlet. SOLUTION: This device calculates a temperature Tbin of a mixing gas in a junction of the intake manifold and the exhaust recirculating pipe 51 from each flow rate Gaact, Gegr, each temperature Ta, Tegr, and each specific heat Cair, Cegr of fresh air and EGR gas flowing into the intake manifold 31, and specific heat Cave and flow rate Gall= Gaact + Gegr of intake air which is the gas mixture (fresh air + EGR gas) of these gases. The temperature Tbout at the intake manifold outlet is calculated from temperature changed from the temperature Tbin by "heat transfer rate ηim × (Tbin - intake manifold wall temperature Twallim)" when this gas passes through the intake manifold.

摘要： PROBLEM TO BE SOLVED: To control an internal combustion engine mounted with a variable turbo-supercharger and an EGR (Exhaust Gas Recirculation) device while suppressing the undershooting/overshooting of an EGR rate or an EGR amount during finishing acceleration to avoid the temporary worsening of exhaust gas.
SOLUTION: In a target value lowering period when a target value r
2 for intake pipe pressure y
2 falls down, cylinder pressure lowers accompanied by the reduction of a fuel injection amount to gradually reduce an output of an exhaust turbo supercharger. In such a circumstance that the intake pipe pressure y
2 naturally lowers toward the target value r
2 , deviation in the intake pipe pressure given to a servo controller 51 is fixed to be zero. Thus, there arises no risk that the servo controller 51 abruptly operates the variable nozzle of the supercharger, thus avoiding the undershooting/overshooting of the EGR rate y

摘要翻译：要解决的问题：为了控制安装有可变涡轮增压器和EGR（排气再循环）装置的内燃机，同时在精加工期间抑制EGR率或EGR量的下冲/过冲，以避免废气临时恶化。
解决方案：当进气管压力y 2 的目标值r 2 的目标值降低期间下降时，气缸压力降低伴随着燃料的减少喷射量逐渐减小排气涡轮增压器的输出。在进气管压力y 2 自然降低到目标值r 2 的情况下，给伺服控制器51的进气管压力的偏差固定为零。因此，不存在伺服控制器51突然操作增压器的可变喷嘴的风险，从而避免了EGR率y 1 的下冲/过冲。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To avoid, in an EGR control of an EGR device associated with an internal combustion engine, a temporary drop of a supercharging pressure or an EGR rate at a timing of transition from a negative pressure range to a supercharging range. SOLUTION: Upon relying on an operation by a servo controller in transition to the supercharging range, for an opening of a nozzle vane of a variable turbo, which is fixed in the negative pressure range, the opening of the nozzle vane is changed gradually toward a control input value u 2 calculated by the controller based on a previous fixed value u H , and during this, control input values given to an EGR valve and a throttle valve are corrected to reduce a deviation of a supercharging pressure y 2 and the EGR rate.

SOLUTION: The cetane number estimation method is applied to a diesel engine 20, in which base injection injecting fuel of an amount depending on an engine operation state and auxiliary injection injecting the fuel of a predetermined amount related to estimation of the cetane number of the fuel are performed.

The auxiliary injection at the reference compression end temperature is performed, and the increased amount of the engine torque along with the auxiliary injection is calculated. The cetane number of the fuel is estimated based on the relation between the increased amount and the reference increased amount. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a systematized fuel injection control method for a diesel engine capable of divided injection of fuel. SOLUTION: A total fuel injection amount is calculated from a torque required by an engine. A division ratio of a pre-injection amount that achieves both suppression of ignition delay of fuel from a main injection and suppression of a peak value of a heat production ratio of combustion from the main injection is calculated. Upper and lower limit guards are given to the obtained divided amount, and the divided injection amount is calculated. The injection amount of the main injection is obtained by subtracting the divided injection amount from the total fuel injection amount. Effective reduction of combustion noise and reduction of NOx emission can be materialized by carrying out pre-injection with the obtained divided injection amount. COPYRIGHT: (C)2009,JPO&INPIT
