摘要： PROBLEM TO BE SOLVED: To restrain/eliminate knocking over a wider internal combustion engine operation range in a spark ignition type internal combustion engine.
SOLUTION: A control unit determines a hydrogen injection quantity and a gasoline injection quantity on the basis of an operation state of the internal combustion engine 10, and injects gasoline by driving a fuel injection valve in the ordinary timing. The control unit directly supplies hydrogen H
2 in a cylinder 11 by driving a hydrogen injection valve HIJ at a compression stroke, and the supplied hydrogen H
2 flows up to a diagonal position of the hydrogen injection valve HIJ along an inner wall surface of the cylinder 11. Then, a part of the hydrogen H
2 mutually collides/merges, and flows to the vicinity of a spark plug 31, and as a result, a thick area of the hydrogen concentration is formed in the vicinity of the spark plug 31 and an area along an inner peripheral wall surface of the cylinder 11.

摘要： PURPOSE:To visualize gasification performance of gasoline by forming a gasoline mixture with air after addition of an N, N-dimethylaniline and naphtalene to the gasoline, by casting ultraviolet laser to the mixture gas and by taking separately photos of fluorescence, emitted from both gas phase and liquid phase thereof. CONSTITUTION:In this invention, ordinary gasoline and additives on the market are used but characteristic of the additives such as purity thereof is selected so as to enable visulalized measurement thereof which is the purpose of this invention. Wave length of ultraviolet laser is also selected to be shorter one than that of fluorescence of the additives. To photograph separately the fluorescence generated from both of gas phase and liquid phase thereof, optical filters through which only the fluorescence from the gas phase or the liquid phase can pass, are set in front of a camera. The gasoline is put into an optical cell after addition of the additives, the ultraviolet laser is radiated and then the liquid phase fluorescence is measured by a spectrometer and a light detector. Furthermore, the gas phase fluorescence is measured, too. As the result thereof, a longitudinal axis in the Figure shows wave length thereof and a vertical axis thereof shows relative strength of the fluorescence, respectively. Both fluorescence peaks from the gas phase and the liquid phase are apparently separated in the Figure.

摘要： PROBLEM TO BE SOLVED: To enable a large amount of EGR in a cylinder direct injection engine with a supercharger. SOLUTION: In a cylinder direct injection engine directly injecting fuel such as gasoline into the inside of a cylinder, the post-treatment of NOx becomes difficult because of burning a lean mixture, and conducting a large amount of EGR is needed for reducing the NOx. If a supercharger is provided on the cylinder direct injection engine so as to increase output, the pressure of an intake passage is higher than the pressure of an exhaust passage, so that EGR becomes impossible. For this reason, internal EGR is conducted by changing valve timing of an intake valve and a exhaust valve, or providing a exhaust shutter in the exhaust passage to let exhaust gas remain in the cylinder or the intake passage. When external EGR is conducted, an EGR port at an end of an external EGR pipe is opened between the supercharger and a pressure control valve provided upstream to the supercharger, and an ordinarily throttle valve is provided downstream to the supercharger.

SOLUTION: A swirl port 14a and a straight port 14b are provided on a cylinder head 10 of an engine, and an intake air control valve 32 is provided on an intake air passage 20b to be connected to the side of the straight port 14b. Additionally, a fuel injection valve 26 having two nozzle holes is arranged on a lower side of the intake air passage 20b, and fuel injection is carried out from nozzle holes 24a, 24b provided on the ports 14a, 14b. The nozzle hole 24b on the side of the straight port 14b is arranged at a position adjacent to an upper end of a valve seat of the port, and it is constituted to inject fuel from the nozzle hole 24b so that fuel is directed toward a cylinder head wall surface or a cylinder wall upper part opposing against each other through a valve stem of an air intake valve 15b and a cylinder central axis in a latter half of an air intake process at the time of closing the intake air control valve 32.

摘要： PURPOSE:To improve the combustion over the entire load region by constructing such that a first injection valve opens at a low pressure in tube with a low injection flow while a second injection valve opens at a high pressure in tube with a high flow characteristic. CONSTITUTION:Under low load, fuel is injected only through a first injection valve 24 having a low open valve pressure. Since the flow characterisitc of the injection valve is low, the pressure in the injection tube increases under heavy load where the injection quantity is large, thereby the fuel is also injected through a second injection valve 26 having a high valve open pressure. The injection valve 24 is directed toward the center of a spherical combustion chamber 14 while the injection valve 26 is directed toward the inner wall face of the combustion chamber 14 in the tangential direction. Since the fuel is injected only from the injection valve 24 toward the center of the combustion chamber 14 where the swirl is weak under low load, premixing of the fuel and the air during the firing lag interval is restricted to slow the combustion. Since the majority of fuel is injected from the injection valve 26 toward the circumferential section of the combustion chamber, and adhered to the inner wall thereof under heavy load, the fuel is evaporated from the inner wall and burnt relatively slowly.

摘要： PURPOSE:To increase the burning speed of the lean air-fuel mixture by making part of a circular groove formed around the axis of a stratified internal combustion engine and extended into a doughnut shape narrower in width than the remaining portion. CONSTITUTION:A central upheaval section 17 is formed at the center section of the top face of a piston 2, and a doughnut-shaped circular groove 18 is formed around the central upheaval section 17. The width t2 of the circular groove 18 located below an exhaust valve 7 is made narrower than the width t1 of the circular groove 18 located below an intake valve 7. A swirl stream is generated around the axis of a cylinder by the intake air stream, and a swirl stream flowing along the circular groove 18 is generated in the circular groove 18.
