Abstract
The utility model relates to a vehicle fuel supply system, which uses a fuel component detecting sensor to control the running of an engine; an engine control device of a heterogeneous alcohol fuel automobile mainly comprises an alcohol fuel oil tank, an alcohol fuel component sensor, a flexible alcohol-fuel engine controller, a common fuel rail and a fuel pipeline, the flexible alcohol-fuel engine controller controls the common fuel rail which is connected with the alcohol fuel oil tank through the fuel pipeline, a nozzle on the common fuel rail sprays fuel so as to ignite the engine, the alcohol fuel component sensor contacts with alcohol fuel, and the output of the alcohol fuel component sensor is connected with the flexible alcohol-fuel engine controller. The alcohol fuel component sensor is arranged at the bottom of the alcohol fuel oil tank. The alcohol fuel component sensor is placed in the fuel pipeline or the common fuel rail. The utility model improves the running characteristic of the engine by adding the alcohol fuel component sensor to detect the fuel components.
Description
Technical field
The utility model relates to a kind of vehicle fuel supply system, controls the device of motor operation by fuel oil composition acquisition sensor; Relate in particular to the automobile that comprises engineering truck and other special cars of Aalcohols fuels such as adopting methanol fuel or ethanol.
Background technique
Present automobile and engineering truck all provide the label of the fuel that uses when dispatching from the factory, methanol and alcohol powered automobile (comprising engineering truck and other special cars) particularly, all provide when dispatching from the factory use the content of methyl alcohol in the fuel or ethanol, such as M15 methanol gasoline, E85 ethanol petrol or the like.If the user does not add fuel on request, perhaps the user is added the fuel that does not meet former factory defined by the gas station under unwitting situation, automobile (comprising engineering truck and other special cars) just has some setbacks work, is short of power, discharges abominable so, even can't work, also can damage motor sometimes because of the fuel improper use.Existing when changing for the fuel oil composition for the control gear of motor, be the fuel injection quantity of revising motor by the lambda sensor at engine exhaust pipe place, be a kind of passive control gear.
The model utility content
The purpose of this utility model is to provide a kind of heterogeneity alcohol fuel automobile engine controlling unit, and this control gear detects propellant composition by increasing pure fuel composition sensor, improves the performance characteristic of motor.
The utility model is achieved in that a kind of heterogeneity alcohol fuel automobile engine controlling unit, mainly comprise pure fuel tank, pure fuel composition sensor, flexible alcohol engine controller, fuel common-rail, fuel line, the alcohol engine controller is controlled fuel common-rail flexibly, fuel common-rail connects pure fuel tank by fuel line, nozzle ejection ignited fuel motor on fuel common-rail, the alcohol fuel composition sensor contacts with pure fuel, and pure fuel composition sensor output connects flexible alcohol engine controller.
Described pure fuel composition sensor is set at pure fuel tank bottom.
Described pure fuel composition sensor is placed in fuel line or the fuel common-rail.
The utility model detects propellant composition by pure fuel composition sensor, to determine the composition of vehicle fuel, and this information passed to flexible alcohol engine controller, the alcohol engine controller just can be regulated engine fuel injection, gas handling system and ignition system to adapt to different fuel automatically according to this signal flexibly, so just can guarantee that motor works in the best condition, thereby reach best Economy, best emission performance.Alcohol engine controller or car load instrument control unit can show the composition of institute's fueling by automobile face table flexibly.
The utility model goes for pure gasoline working state, pure methyl alcohol or ethanol working state and multiple mode of operations such as flexible hybrid working state that both use simultaneously.

Among the figure: 1 fuel oil component sensor, 2 fuel (oil), 3 fuel lines, 4 motors, 5 fuel common-rails, 6 flexible alcohol engine controllers, 7 fuel tanks.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of heterogeneity alcohol fuel automobile engine controlling unit mainly comprises pure fuel tank 7, pure fuel composition sensor 1, flexible alcohol engine controller 6, fuel common-rail 5, fuel line 3.Alcohol engine controller 6 is controlled fuel common-rails 5 flexibly, and fuel common-rail 5 connects pure fuel tank 7 by fuel line 3, nozzle ejection fuel 2 ignition engines 4 on fuel common-rail 5.Described pure fuel composition sensor 1 is fixedly installed on pure fuel tank 7 bottoms, pure fuel composition sensor 1 is contacted with pure fuel 2,1 output of alcohol fuel composition sensor connects flexible alcohol engine controller 6, and 2 one-tenth sub-signals of fuel are sent to flexible alcohol engine controller 6.After flexible pure fuel-control unit 6 has been taked the signal of pure fuel composition sensor 1, can control motor 4 according to the pure propellant composition that this signal reaction goes out.Described pure fuel composition sensor 1 is the dielectric sensing device.Alcohol fuel composition sensor 1 also can be placed in fuel line 3 or the fuel common-rail 5.
In fuel tank 7, also be set with liquid level sensor, fuel in the fuel tank 7 what are used to detect; Fuel pump is fixed on the support in fuel tank 7 outsides, is connected with the low-voltage fuel pipe with 7 of fuel tanks; Fuel common-rail 5 is fixed on the support on the engine intake manifold; Fuel nozzle is arranged between fuel common-rail 5 and the intake manifold, directly is connected with both.
Above-mentioned flexible alcohol engine controller 6 comprises input processing, computing, output processing circuit, input processing circuit is made up of filtering, amplification, analog conversion circuit, and comprise the signal processing circuit of pure fuel composition sensor 1, sensor input signal is handled.
After using the utility model, automobile just can use the Aalcohols fuel of any ratio, also can use 100% Aalcohols fuel, also can use pure Fuel Petroleum.There has been behind the utility model autoist also can know the pure content of institute's fueling, thereby supervised the gas station by the demonstration of instrument panel.
