摘要： PROBLEM TO BE SOLVED: To suitably switch operating conditions of an internal combustion engine from compressed self-ignition operation to spark ignition operation.
SOLUTION: When the operating conditions are switched from the compressed self-ignition operation to the spark ignition operation according to increase of target torque, a quantity of fuel injection is once gradually increased in a condition of stratified spark ignition operation and air-fuel ratio of a fuel-air mixture is gradually decreased. Then, when the air-fuel ratio is decreased to a predetermined value, the operation is switched into the spark ignition operation while the air-fuel ratio is decreased to a theoretical air-fuel ratio at a stretch. Thus, the operating conditions can be stably switched by passing through the stratified spark ignition operation, and output torque is not rapidly increased and the operating conditions can be switched without sense of incongruity by switching the operating conditions while gradually increasing the fuel. Further, discharge of atmospheric pollutants such as nitrogen oxides is not increased by switching the air-fuel ratio to the theoretical air-fuel ratio at a stretch when the air-fuel ratio reaches predetermined air-fuel ratio.

摘要： PROBLEM TO BE SOLVED: To make a stable, quick switch to self-ignition in an engine which uses both spark ignition and self-ignition.
SOLUTION: A combustion method of the engine is switched to self-ignition of two cycles or spark ignition of four cycles in accordance with rotation speed and required load. At the time of switching from the spark ignition to the self-ignition, processing for raising temperature of compression end is applied in order to realize stable self-ignition when temperature of exhaust is low, whereas the processing is skipped when temperature of exhaust is high. Quick switching can be realized while simultaneously starting stable self-ignition by judging whether not or processing for raising the temperature of the compression end is required on the basis of the temperature of the exhaust.

摘要翻译：要解决的问题：在使用火花点火和自点火的发动机中，使自动点火稳定快速切换。
解决方案：根据转速和所需负载，发动机的燃烧方式切换为两个循环的自点火或四个循环的火花点火。在从火花点火切换到自点火时，施加压缩端温度的加工，以便在排气温度低时实现稳定的自点火，而当排气温度高时，跳过加工。可以通过基于排气的温度判断是否需要提高压缩端的温度来进行加热，同时开始稳定的自点火，实现快速切换。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To smoothly switch a four-cycle operation and a two-cycle operation in a variable cycle engine. SOLUTION: An engine has a first operational mode to perform the four-cycle operation and the two-cycle operation while igniting fuel in a fuel chamber by an ignition unit. The first operational mode comprises a first normal mode of relatively high real compression ratio and a first transition mode of relatively low real compression ratio which is performed before starting the first normal mode after completing the second operational mode. The four-cycle operation is smoothly switched from the two-cycle operation without any knocking by performing the operation in the first transition mode of relatively low real compression ratio.

摘要： PROBLEM TO BE SOLVED: To provide an ignition plug that is able to effectively hinder occurrence of pre-ignition due to high temperature of gas mixture staying in a plug pocket.SOLUTION: An ignition plug 1 comprises a housing part 2, an insulator 3, a center electrode 4, and a ground electrode 5. The ignition plug 1 also has a plug pocket P. In the ignition plug 1, where the length units are made identical, the plug pocket P is formed so as not to be smaller than 1.1 in an index value Pv/S4, which is obtained by dividing the volume Pv of the plug pocket P by an area S4 that is the surface area of the portion of the insulator 3, which portion is adjacent to the plug pocket P. A generation temperature T when the index value Pv/S4 is smaller than 1.1 tends to become greater in the degree of increase with an increase in the index value Pv/S4, compared to the case where the index value Pv/S4 is larger than 1.1.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust recirculating device of an internal combustion engine capable of restraining generation of a sulfuric acid, while properly securing recirculation of exhaust gas.
SOLUTION: An ECU 100 predicts the generation of the sulfuric acid caused by cooling recirculating exhaust gas recirculated to an intake passage 20 from an exhaust passage 30, and selectively puts the exhaust passage 30 on the upstream side of a catalyst 31, the exhaust passage 30 on the downstream side and the intake passage 20 in a communicating state in response to this predicting result. With this constitution, since the sulfur component concentration included in respective exhaust gases is different between the upstream side exhaust gas and the downstream side exhaust gas, the generation of the sulfuric acid can be restrained by properly securing the recirculation by selectively recirculating the upstream aide exhaust gas and the downstream side exhaust gas to an intake system in response to a generation predicting result of the sulfuric acid.
