Description
Technical field
The utility model relates to technical field of internal combustion engines, and relating to a kind of air displacement specifically is 1.9L high-pressure common rail charge inter cooling diesel engine gas handling system.
Background technique
In recent years, along with automobile pollution ground, various countries constantly increases, relevant department is also more and more stricter to the restriction of motor vehicle emission.In Europe, Europe III, Europe IV emission standard require in vogue, can carry out Europe V, Europe VI standard afterwards very soon.And in China, the product of Europe III has also replaced the comparatively abominable automobile of discharging gradually, and can progressively implement Europe IV, Europe V standard in recent years.In addition, along with global resources are more and more deficienter, the especially shortage of oil, energy-saving consumption-reducing also becomes the major requirement of Automobile Motor Design.Therefore, for further improving the Economy and the emission performance of automobile, to satisfy the above emission request of Europe IV, increasing motor car engine has adopted advanced technology.But when the low engine speed low-load, combustion efficiency reduces, and fuel consume increases relatively, and emission performance is poor; When the high engine speeds high load, the raising of intake efficiency is restricted, thereby causes the raising of engine output to be restricted.
The model utility content
For Economy and the emission performance that improves motor, solve diesel engine variable air input problem, the utility model provides a kind of 1.9 liters of high-pressure common rail turbocharged and intercooled diesel engine gas handling systems with variable air input.
The Technological improvement plan of realizing above-mentioned purpose is as follows:
Comprise intake manifold body, exhaust gas recirculation valve connecting tube 1.9 rise high-pressure common rail turbocharged and intercooled diesel engine gas handling system; Described intake manifold body adopts split type aluminum casting, is divided into upper body and lower body, is called intake manifold and intake elbow.Intake manifold cooperates with cylinder cap, cooperates a side totally 8 intake ducts with cylinder cap, and the air inlet of every cylinder double air passage is respectively inflation air flue and swirl air passage, and swirl air passage is designed to arch for avoiding controlling valve rod; Opposite side is provided with main air inlet, and an end of described intake elbow is communicated with the main air inlet of intake manifold; Split type intake manifold makes things convenient for the installation of control valve.
Described intake manifold bottom is provided with the intake manifold support, guarantees the Security of inlet end part time job and the vibration of minimizing motor.
Eddy current control valve mechanism is installed on the intake manifold body, and when the low engine speed low-load, control valve is closed the inflation air flue, has only the swirl air passage can air inlet, to increase the intake swirl of motor, makes fuel-oil atmozation better; In the high speed high load, control valve is opened, and the double air passage air inlet increases air inflow, to obtain required drive.Motor is controlled its burning by control valve, reduces the low speed fuel consumption rate of motor, improves the Economy and the emission performance of motor.
The beneficial effects of the utility model are: these 1.9 liters of high-pressure common rail turbocharged and intercooled diesel engine gas handling systems are variable volume intake system, air inlet according to different operating mode control motors, when adopting the low engine speed low-load of eddy current control technique, closed by the vacuum solenoid of electronic control unit controls, degree of vacuum can not enter eddy current control valve final controlling element, and eddy current control valve block is closed.Because gas-entered passageway diminishes, and produces a powerful eddy current, this has just improved combustion efficiency, saves fuel consume, improves emission performance simultaneously.When the high engine speeds high load, electronic control unit is connected the vacuum solenoid circuit according to signals such as rotating speed, temperature, air inflows, vacuum solenoid is opened, degree of vacuum enters eddy current control valve final controlling element, the eddy current control valve is opened, it is big that gas-entered passageway becomes, and improves intake efficiency, thereby improve engine output.
