    摘要： A combustion pressure control system of a spark ignition type of internal combustion engine which has a sub chamber 60 which is communicated with a combustion chamber 5, wherein the system is provided with a volume changing device which changes a volume of the sub chamber 60 by a change of pressure of the combustion chamber 5 serving as a driving source when the pressure of the combustion chamber 5 reaches a control pressure. The control pressure is set in a range of larger than a maximum pressure of the combustion chamber 5 in the case of suspending the supply of fuel and less than the pressure at which abnormal combustion of the fuel occurs. The volume changing device is formed so that when the pressure of the combustion chamber 5 reaches the control pressure during the period from a compression stroke to an expansion stroke of a combustion cycle, the volume of the sub chamber 60 becomes larger and a rise of the pressure of the combustion chamber 5 is suppressed.

    摘要： A direct injection spark ignition internal combustion engine includes a fuel injection valve and fuel injection control device that controls fuel injection such that a fuel is injected from an upper area of an engine cylinder toward a top face of a piston through the fuel injection valve. The fuel injection control device switches a thrust force of the fuel injected from the fuel injection valve between at least two levels such that the thrust force of the injected fuel becomes weaker when the position of the piston is high than when the position of the piston is low.

    摘要： A direct injection spark ignition internal combustion engine includes a fuel injector for directly injecting fuel into a cylinder and intensifies a tumble flow using the fuel injected into the cylinder bore at a time near an intake stroke bottom dead center during homogenous combustion. The thrust force of the fuel injected from the fuel injector is set to intensify the tumble flow based on at least one of the state of the combustion chamber, the temperature of the injected fuel, and the orientation of the injection hole.

    摘要： An internal combustion engine is provided with a sub chamber which is communicated with a combustion chamber and with a variable volume device which changes the volume of the sub chamber. The variable volume device includes a communication part arranged at a cylinder head and formed into a tubular shape, a movement member which is formed in a tubular shape so as to engage with the inside of the communication part and which has a closed end at the side facing the combustion chamber, and a support part which has a projecting part which engages with the inside of the movement member. The variable volume device has the space at the inside of the communication part divided by a movement member and is formed with a sub chamber and gas chamber. The movement member has an open end at the opposite side to the side facing the combustion chamber and is formed so that gas in the gas chamber which leaks from the parts where the movement member and the projecting part contact is discharged to the outside of the cylinder head.

    摘要： An internal combustion engine is provided with an exhaust valve which has a tapered plug part, a tube-shaped member which is arranged in a region where the exhaust valve is arranged and which is engaged with the tapered plug part of the exhaust valve at one end part which faces a combustion chamber, and a fluid spring for biasing the tube-shaped member to the side facing the combustion chamber. The tube-shaped member is formed so as to be able to move substantially parallel to the direction of movement of the exhaust valve and the other part abuts against the fluid spring. The fluid spring is formed so as to contract using the change in pressure of the combustion chamber as a drive source when the pressure of the combustion chamber reaches a predetermined control pressure.
