摘要： An engine ignition system and the like are provided, which reduce a required voltage and improve an ignition performance without any special electrical configuration. An ignition system is configured so that: to an auxiliary electrode is applied a voltage that is not more than a voltage applied between a center electrode and a ground electrode and that generates no spark discharge; the auxiliary electrode is positioned so that an electric field Ef2 between the auxiliary electrode and the ground electrode or an electric field Ef3 between the auxiliary electrode and the center electrode, which is generated by the applied voltage, is spread over the gap. A time for applying the voltage to the auxiliary electrode is controlled to include a time for applying the voltage between the center electrode and the ground electrode.

摘要： An engine device of the present invention includes including: an intake manifold configured to supply air into a cylinder; an exhaust manifold configured to output exhaust gas from the cylinder; a gas injector which mixes a gaseous fuel with the air supplied from the intake manifold; and a main fuel injection valve configured to inject a liquid fuel into the cylinder for combustion. At the time of switching from a gas mode in which the gaseous fuel is supplied into the cylinder to a diesel mode in which the liquid fuel is supplied into the cylinder, a supply-start timing of the liquid fuel is delayed relative to a supply-stop timing of the gaseous fuel.

摘要： An engine device including an intake manifold (67) configured to supply air into a cylinder (36), a gas injector (98) configured to mix fuel gas with air supplied from the intake manifold (67), and supply mixed gas to the cylinder (36), and an igniter (79) configured to ignite, in the cylinder (36) premixed fuel obtained by pre-mixing the fuel gas with the air, the engine device further including a controlling unit (73) configured to determine an air amount in the premixed fuel in the cylinder (36). The controlling unit (73) performs in multiple steps retard control of ignition timing by the igniter (79), when the air amount is insufficient, and performs in multiple steps advance control of the ignition timing, when the air amount is sufficient.

摘要： An engine device of including: an intake manifold configured to supply air into a cylinder; a gas injector configured to mix fuel gas with air supplied from the intake manifold, and supply mixed gas to the cylinder; an igniter configured to ignite, in the cylinder, premixed fuel obtained by pre-mixing the fuel gas with the air; and a control unit configured to execute a combustion control of a premixed fuel based on the output signal indicative of an output from the engine device. When the air amount is determined to be insufficient and when the output signal is lost, the control unit estimates an output signal based on the fuel gas injection amount from the gas injector, and executes the combustion control based on the estimated output signal.

摘要： An engine device executes the control of the opening degree of a main throttle valve when engine load is in a low load area. In contrast, when the engine load is in a medium-to-high load area, the engine device sets the main throttle valve to a predetermined opening degree and executes the control of the opening degree of an air supply bypass valve.

摘要： An engine device including: an intake manifold configured to supply air into a cylinder; an exhaust manifold configured to output exhaust gas from the cylinder; a gas injector which mixes a gaseous fuel with the air supplied from the intake manifold; and a main fuel injection valve configured to inject a liquid fuel into the cylinder for combustion. At the time of switching the operation mode from one to the other between a gas mode and a diesel mode, an instant switching to the diesel mode is executed when the engine rotation number is determined to approach the upper limit value which leads to an emergency stop of the engine device.

摘要： An engine device (21) including: an intake manifold (67) configured to supply air into a cylinder (77), an exhaust manifold (44) configured to output exhaust gas from the cylinder; a gas injector (98) which mixes a gaseous fuel with the air supplied from the intake manifold; and a main fuel injection valve (79) configured to inject a liquid fuel into the cylinder for combustion. At the time of switching the operation mode from one to another between a gas mode and a diesel mode, a supply amount of a first fuel to be supplied in a post-switching operation mode is increased to a switching threshold value through an increase control which monotonously increases the supply amount, and then is controlled by a speed-governing control based on the engine rotation number. The switching threshold value is set based on the engine rotation number or the engine load.
