Abstract
The invention discloses a detection device for oil supply timing of a diesel engine. A connecting block is fixed on a crankshaft pulley of the diesel engine and fixed with a crankshaft corner signal panel; a sensor bracket is fixed on the diesel engine; a sensor is fixed on the sensor bracket and arranged above the crankshaft corner signal panel; a plurality of small holes are formed on the crankshaft corner signal panel in an annular array; metal rods are fixed in the small holes; one of the metal rods is shorter than other metal rods; and a corner signal of the sensor and a lift signal of a lift sensor on a needle valve of the diesel engine are transmitted to an oscilloscope through a signal line. By the device, oil supply time of the diesel engine can be accurately mastered, and the maximum power, the minimum oil consumption and the optimal exhaust gas purification are achieved.
Description
Technical field:
The invention belongs to motor detection technique field.
Background technique:
Fuel injection timing is meant the supply time that Injection Pump is correct, represents with fuel supply advance angle.The size of fuel supply advance angle is very big to the working procedure influence of diesel engine.When fuel supply advance angle is excessive, rapid combustion period in the cylinder took place in the past at compression end of a period top dead center, the peak value of the pressure of explosion in the cylinder occurred in the past at the piston arrives top dead center, and this will cause power to descend, work is slightly quick-fried, oil consumption increases, catch fire that knock is serious, rough idle, acceleration is unable and phenomenon such as starting difficulty.When fuel supply advance angle was too small, the rapid combustion period in the cylinder took place in compression end of a period atdc, and the peak value of pressure of explosion is reduced, and caused power decline, oil consumption to increase, quicken phenomenons such as unable equally, and can cause engine overheat.
The rotor Injection Pump is equipped with the fuel supply advance angle automatic control regulator, can regulate automatically with change in rotational speed on the basis of static fuel supply advance angle.Dress can't accurately be measured and the dynamic fuel supply advance angle of adjustment diesel engine with traditional method with the diesel engine of rotor pump, causes diesel engine performance to guarantee.
Summary of the invention:
Purpose of the present invention is exactly the deficiency at prior art, and a kind of detection device of diesel engine fuel injection timing is provided, and it can realize accurately grasping the diesel engine supply time, obtains peak output, minimum oil consumption and best exhaust gas purification.
Technology solution of the present invention is as follows:
The detection device of diesel engine fuel injection timing, comprise metal bar, the corner signal dish, contiguous block, crank pulley, sensor, sensor stand, signaling line, the needle lift sensor, oscillograph and diesel engine, on the crank pulley of diesel engine fixedly connected, contiguous block and corner signal dish are fixed together, on diesel engine, be fixed with sensor stand, sensor is fixed on the sensor stand and places corner signal dish top, circular array is shown several apertures on the corner signal dish, metal bar is fixed in this aperture, wherein a metal bar is shorter than other metal bar, and the angular signal of sensor and the lift signal of the lift range sensor on the needle-valve on the diesel engine flow to oscillograph by signaling line.
Described metal bar has 72, and wherein the short metal bar of that root is contained in the tdc position on the corner signal dish.
Beneficial effect of the present invention is: it can realize accurately grasping the diesel engine supply time, obtains peak output, minimum oil consumption and best exhaust gas purification.
