摘要： PROBLEM TO BE SOLVED: To reduce fuel consumption quantity without inducing deterioration of combustion in low load zone of an internal combustion engine.
SOLUTION: Pressure in a combustion chamber 22 falls down at combustion stroke in the internal combustion engine 10. Crank angle immediately prior to negative pressure is calculated as desired crank angle by engine rotary speed NE by means of load of the internal combustion engine 10 and a crank angle sensor 28 based upon intake quantity QA from an air flow meter 13. A variable valve timing control mechanism 30 is controlled so that the crank angle at opening timing of an exhaust valve 24 is coincident with the desired crank angle, thereby no negative pressure exists in the combustion chamber 22 in the low load zone of the internal combustion engine 10. A device can reduce the fuel consumption quantity without inducing deterioration of the combustion in the low load zone of the internal combustion engine being able to avoid pumping loss as exhaust loss.

摘要： PROBLEM TO BE SOLVED: To reduce adhesion of particulate to the interior of an intake pipe and to eliminate a need to perform after-processing of particulate accumulated at a filter by a method wherein the end part on the exhaust pipe side of an exhaust gas conduit, communicated with an intake system, is protruded in an exhaust pipe and the terminal opening thereof is pointed to the direction of a flow of exhaust gas. SOLUTION: A part of exhaust gas discharged in an exhaust pipe 3 from an engine 1 flows through the terminal opening 42 of an EGR conduit 4 to an intake pipe and is mixed with intake air. The maximum combustion temperature of the engine 1 is decreased by the mixture and oxidation reaction of nitrogen is suppressed. In this case, the end part 41 of the EGR pipe 4 is extended through an exhaust pipe 3 wall and protruded in the exhaust pipe 3, and bent in an L-shape to the opposite side to the engine 1 at the central part of the cross section of the exhaust pipe 3, and a terminal opening 42 is pointed to a spot situated downstream of an exhaust gas flow. This constitution reduces an amount of particulate adhered and accumulated on the intake pipe and eliminates a need to mount a member for capturing the particulate in the EGR conduit 4.

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.
