摘要： PROBLEM TO BE SOLVED: To properly inject fuel in a starting period of an internal combustion engine.
SOLUTION: In the starting period of the engine 200, an ECU 100 calculates a incremental coefficient FASE for increasing a reference injection amount T
P by multiplying the previous coefficient FASE by a rate B of change in coefficient every update timing. The rate B of change in coefficient adopts at least two kinds of values depending on elapsed time after the starting, and therefore, the coefficient FASE has a characteristic temporally increasing with respect to the elapsed time.

摘要： PROBLEM TO BE SOLVED: To optimally control supply of the air-fuel mixture to an internal combustion engine independently of a change of the fuel condition with consumption of the vapor-liquid fuel mixture.
SOLUTION: H/C ratio Rhc of the air-fuel mixture in the gaseous condition is computed on the basis of a detected concentration B of butane (S150). A theoretical air-fuel ratio Rt is computed on the basis of the H/C ratio Rhc (S200). A correction coefficient Ka of a fuel injection period is computed on the basis of the concentration B of butane and the theoretical air-fuel ratio Rt (S250). A basic fuel injection period Tb as the optimal fuel injection period when the natural gas is contained at 100 % is computed (S300). A first target fuel injection period T1 is computed on the basis of the basic fuel injection period Tb and the correction coefficient Ka (S400). A second target fuel injection period T2 for reducing a deviation between the real air-fuel ratio Ra and the theoretical air-fuel ratio Rt is computed (S450). A fuel injection period in relation to an air intake pipe 32 by a fuel injection device 28 is controlled on the basis of the final target fuel injection period Tt as the sum of the first and the second target fuel injection periods (S500, S550).

摘要： PROBLEM TO BE SOLVED: To prevent fluctuation of a fuel injection amount for the same valve open time of an injector by restraining pressure pulsation of fuel inside a fuel piping in a fuel supply system of an internal combustion engine. SOLUTION: In this system, pressure mitigating device 5 connected to a high pressure fuel piping is provided, and damper chamber 11 is formed inside the pressure mitigating device 5, valve bodies 12, 13 are provided to openings 9a, 10a of partitions 9, 10, respectively, whereby urging in a valve close direction is always performed by a spring 14. When a high pressure part comes to an inlet of the damper chamber 11, the valve element is positioned to open the valve, and the high pressure is enclosed and absorbed in the damper chamber 11. When a low pressure part comes to the inlet, the high pressure part is discharged gradually via a restriction opening 12a or 13a and the low pressure part is canceled. Accordingly, pressure pulsation of a fuel can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a flow noise control system that is able to check any noise to be produced at a time when a throttle valve installed in an intake passage or the like of an internal combustion engine is opened. SOLUTION: Two circular low barrier members 9 and 10 are installed in an inner wall surface 6 of an air passage 2 at the downstream side of a throttle valve 3 as a resistant means imparting a resistor to a flow passing through a vertical pair of clearances 7 and 8 to be formed at the valve opening initial stage of this valve 3. Therefore flow velocity and flow rate in the flow passing through these clearances are decreased, whereby the extent of noises to be produced when flows out of the paired clearances 7 and 8 are joined together is reduced. The barrier members 9 and 10 may be plurally installed in parallel, or deformed to some extent as well. In addition, as another resisting means, fins of more than one piece along a central axis of the air passage may be used as well. Moreover, in place of the resisting means, a turbulence generating means such as dimples made up on the inner wall surface 6 and such a wire as extending to the downstream side along the central axis of the air passage may be installed to generate a turbulent flow along the inner wall surface 6.

摘要： PROBLEM TO BE SOLVED: To provide an intake device of an internal combustion engine which can generate a tumble stream in response to an engine operating condition by preventing a liquid reservoir of a fuel near a downstream side of an intake flow control valve.
SOLUTION: The intake control valve 4 is provided at an intake tube 2, and a main opening 4A for passing air is formed at an upper part of the valve 4. A sub-opening 4B having an opening area smaller than that of the opening 4A is formed at a lower end central part of the valve 4. When the vale 4 is closed, the tumble stream can be generated by the air flowing from the opening 4A. The fuel included in the air rewound by an intake channel 22 can be pushed back to the downstream side by the air flowing through the sub-opening 4B.

摘要： PROBLEM TO BE SOLVED: To prevent responsiveness of a control from lowering due to adhering of fuel in an oil film state to an intake port and a cap part of an intake valve, and to prevent becoming deposits, during low load of an internal combustion engine.
SOLUTION: A jet port 1 is provided in the intake port 6a on a large flow rate side of the two intake ports 6a and 6b to form a swirl 10 within a combustion chamber, and additional intake air is supplied from the intake valve 7a on the large flow rate side. In this air-fuel mixture supply system, fuel is injected to only the intake port 6a on the large flow rate side from a fuel injection valve 8. Even when fuel is injected to the other intake port 6b, the amount is reduced. Since the injected fuel flows into the combustion chamber with strong air flow, fuel does not adhere to an inner wall surface of the intake 6a and the cap part of the intake valve 7a.

摘要翻译：要解决的问题：为了防止由于油膜状态的燃料粘附到进气门和进气门的盖部分而导致的控制器的响应性降低，并且为了防止沉积，在内燃机的低负荷期间。解决方案：在两个进气口6a和6b的大流量侧的进气口6a中设置有喷射口1，以在燃烧室内形成涡流10，并且从进气门7a向其提供额外的进气大流量侧。在这种空气燃料混合物供给系统中，燃料仅从燃料喷射阀8向大流量侧的进气口6a喷射。即使在向另一个进气口6b喷射燃料的情况下，也减少了燃料量。由于注入的燃料以强的气流流入燃烧室，所以燃料不粘附到进气口6a的内壁表面和进气门7a的盖部分。
