摘要： An injection arrangement for an internal combustion engine, especially a diesel engine, for injecting different pressure media directly into a cylinder of the engine, which arrangement includes a first valve (3) for controlling injection of fuel into the engine cylinder and a second valve (4) for controlling injection into the engine cylinder of an additional medium for decreasing the content of noxious substances resulting from combustion of the fuel. The second valve (4) comprises a preferably elongate valve member (5) movable within a valve body (2) between open and closed positions, urged by a spring (12) towards its closed position and, in association with a part of which is located on the cylinder side, there is arranged a chamber (6) which surrounds the valve member (5) and into which said additional medium is arranged to be fed continuously under pressure. The chamber (6) is limited at its end remote from the cylinder by a step in the valve member (5) which serves as a piston surface (7) and is so dimensioned that the mere pressure of the additional medium fed into the chamber (6) is not sufficient to move the valve member into its open position to open the valve (4) for effecting injection. In addition the arrangement comprises a control valve (27) controlled by an electric signal (35) and which, under the influence of the control signal (35), is arranged to effect, together with the pressure of the additional medium acting on the piston surface (7), movement of the valve member (5) into its open position to open the valve (4) for injection of the additional medium into the cylinder.

摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine employing liquid fuel and gas fuel as the fuel, wherein the air-fuel ratio of exhaust gas is periodically changed from lean to rich and from rich to lean so as to keep a catalyst purifying performance high.
SOLUTION: Correction factor (gasoline FAF) for correcting an injection amount of liquid fuel (for example, gasoline) and a correction factor (hydrogen FAF) for correcting an injection amount of gas fuel (for example, hydrogen) are independently prepared. The phase difference (delay time) is set between the correction factors so that a phase of a cylinder air-fuel ratio materialized by injection of the liquid fuel coincides with that materialized by injection of the gas fuel.

摘要： PROBLEM TO BE SOLVED: To surely suppress the knocking in an internal combustion engine in which gasoline is mainly used, in a control device of the internal combustion engine.
SOLUTION: A gasoline injection valve 30 is installed to directly inject gasoline into a cylinder. A hydrogen injection valve 38 is installed to inject hydrogen gas into an intake passage 18. An ignition plug 28 is installed to ignite an air-fuel mixture of hydrogen and air fed into the cylinder by the hydrogen injection valve 38. Gasoline is fed into the cylinder by the gasoline injection valve 30 almost at the same time as the hydrogen ignition by the ignition plug 28 or at the timing delayed from the ignition.

摘要： PROBLEM TO BE SOLVED: To provide a premix compression ignition internal combustion engine for allowing stable combustion regardless of an operation load of the internal combustion engine by restraining the occurrence of excessively early ignition when performing premix combustion in a compression ignition internal combustion engine for injecting fuel of multiple times in one cycle. SOLUTION: This compression ignition internal combustion engine has a main fuel injection valve for injecting main fuel and a sub-fuel injection valve for forming premix air of sub-fuel and air in a combustion chamber by injecting the sub-fuel in the earlier timing than the main fuel. When determining that the ignition timing of the premix air is earlier than the prescribed timing on the basis of the air-fuel ratio of the premix air formed in at least the combustion chamber (S100, S101 and S102), a temperature of the sub-fuel is reduced (S104), or when having an exhaust air recirculating device, a temperature of recirculating exhaust air is reduced by the exhaust air recirculating device.
