Description
Technical field
The present invention relates to air inlet and the fuel supply system of gas engine, specifically refer to that a kind of gas engine combustion gas advances the cylinder quantity control valve.
Background technique
The work of gas engine rely on electrical system by combustion gas with send into the engine cylinder-body internal combustion after air mixes by a certain percentage and do work to realize.Combustion gas mixes with air generally to be carried out in the upstream of engine intake manifold.
As shown in Figure 1, existing air inlet and gas supply system adopt the mixer pre-mixing type usually, be characterized in that combustion gas and air all enter the interior mixing of mixer 14, the mixed gas E of the basicly stable air fuel ratio that is maintained, air intake branch 16 through engine intake manifold 15 and each cylinder 17 enters each cylinder again, the performance of the mixer that motor configures directly affects the performance index of motor, and the advantage of this air inlet and gas supply system is easy reliable, the good stability that keeps air fuel ratio.
Yet the defect of above-mentioned air inlet and gas supply system is:
(1) can not be applicable to the combustion gas that velocity of combustion is fast, fire extend is large, this is because during engine operation, inflammable mixture abrim in whole suction tude, so combustion gas that contains hydrogen and CO (carbon monoxide converter) gas large for fire extend, that velocity of combustion is fast, the tendency of its tempering and dangerous serious, so Security is poor;
(2) can not give full play to the advantage of supercharging type, because be full of inflammable gas in whole suction tude, can only adopt non pressurized type valve overlap, to avoid inflammable gas directly to overflow from outlet pipe when the scavenging, so the gas engine of supercharging has to adopt unsupercharged valve overlap, causes row's temperature high, the strengthening degree is low, the thermal efficiency is low, and the gas consumption rate is high, and the output power of motor is very restricted;
(3) it is longer that combustion gas enters cylinder pipeline before, and gas quantity is regulated dynamic difference in response.
In order to overcome existing gas engine air inlet and the existing above defect of gas supply system, need to take the mode by cylinder supply combustion gas, combustion gas is mixed in cylinder with air.Yet, the combustion gas of existing gas engine is controlled and is quantitatively controlled for complete machine, quantity control valve is pipeline throttling type dish valve, degree of regulation is poor, be only suitable for regulating in the gas flow that line size is large, pressure is extremely low, flow is larger, can not meet by cylinder supply gas quantitative and control the requirement that flow is less, pressure is higher, degree of regulation is high.And although more existing gas flow control valves can meet by cylinder supply gas quantitative control requirement, but due to must be according to the working state of cylinder as situation automatic control and adjustment gas flow sizes such as each working stage such as the starting of motor, speed governing, each cylinder load distribution, parkings, the requirement of the automatic control and adjustment while therefore making existing gas flow control valve still be difficult to meet for above-mentioned engine behavior, therefore existing gas flow control valve can't directly apply in described gas supply system.
