Abstract
The invention discloses a signal generating device of an automobile engine, and the signal generating device comprises a main body, a signal panel, a rotating shaft, a gear connecting disc and a bearing, wherein a through cavity is arranged in the middle of the main body, one side of the main body is provided with a concave cavity and communicated with the through cavity, one end of the rotating shaft is plugged inside the through cavity of the main body and connected into the main body through the bearing, the end of the rotating shaft, which is plugged into the main body, is connected with the signal panel, the signal panel is arranged inside the concave cavity of the main body, and the other end of the rotating shaft stretches out of the main body to be connected with the gear connecting disc. The signal generating device has advantages of simplicity in structure, stability, reliability, economy, practicability and the like, and is particularly suitable for the automobile engine for modifying a diesel engine to a natural gas engine.
Description
Technical field
The present invention relates to a kind of parts of motor car engine, specifically a kind of signal occurrence device of motor car engine.
Technical background
DENG is that burning diesel oil obtains exergonic motor, advantages such as power is big, economic performance is good that it has.Because the fuel of use for diesel engine is diesel oil, its ratio of viscosities gasoline is big, be difficult for evaporation, and its SIT is low than gasoline, so the formation of inflammable mixture and firing mode are all different with petrol engine.As vehicle fuel, biggest advantage is exactly low contaminativity with rock gas.Under the existing technology condition, the discharge capacity of pollutant is well below traditional petroleum fuel automobile in the natural gas and auto tail gas.Experiment shows, the CO in the natural gas vehicle exhaust
2Discharge amount can reduce 19%-25%, and the CO discharge amount can reduce 90%-97%, NO
XDischarge amount can reduce 30%-50%, SO
2Discharge amount can reduce 70%-90%, and the microparticle thing reduces about 40%.The development gas-fueled vehicles are the important behaves that reduce pollution of atmosphere and preserve the ecological environment.Compare with diesel oil at economic aspect in addition, but about cost saving 30%-40%.But required rotating speed and phase signal collection are got up cumbersomely when at present diesel engine refitted being become natural gas engine, need on camshaft, install a device acquisition phase signal, on bent axle, install another device collection tach signal.When on bent axle, gathering tach signal, present way has two kinds: 1. get the speed of crankshaft signal through flywheel, this way causes signal pickup assembly processing difficulties, cost height; Break down easily; Clutch plate one is damaged, and just is prone to speed probe is battered down, and motor can't be turned round; 2. get the speed of crankshaft signal through belt pulley, the sort signal collecting device can only adopt exposed structure, and dust, earth, the grains of sand etc. make its damage easily.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of simple in structure, reliable and stable, economic and practical signal occurrence device that diesel engine refitted is become the required motor car engine of natural gas engine, to give full play to the beneficial effect that rock gas is brought as motor car engine fuel.
For solving the problems of the technologies described above; The signal occurrence device of a kind of motor car engine of the present invention comprises body, signal panel, rotating shaft, gear land and bearing; The centre of said body is provided with cavity, and a side of said body is provided with cavity and is communicated with said cavity, and an end of said rotating shaft inserts in the cavity of said body; And be connected in the said body through said bearing; This end of said rotating shaft is connected with said signal panel, and said signal panel are positioned at the said cavity of said body, the other end of said rotating shaft stretch out said external and link to each other with said gear land.
The signal occurrence device of above-mentioned a kind of motor car engine, it also includes cover plate, and said cover plate is fixed on the outboard end of said body cavity.
The signal occurrence device of above-mentioned a kind of motor car engine, said signal panel are 24 to subtract 1 signal fluted disc.
The signal occurrence device of above-mentioned a kind of motor car engine, said rotating shaft links to each other with said signal panel through the tapering of 1:10.
The signal occurrence device of above-mentioned a kind of motor car engine, said rotating shaft through said bearing and shaft block ring, neck bush, external bushing and hole with the back-up ring support and connection in the cavity of said body.
The signal occurrence device of above-mentioned a kind of motor car engine passes through the flat key positioning and fixing between said rotating shaft and the said gear land.
The present invention links to each other with former high-pressure fuel pump of diesel engine drive part it during installation owing to adopted above-mentioned technical pattern through bolt, as long as at the signal panel place one sensor is installed, just can realize the purpose of signals collecting.The collection of rotating speed and phase signal only needs this device just can accomplish, and is simple in structure.Device is the sealed mode working environment, is not subject to foreign material such as dust, muddy water and damages, and working stability is reliable, and Economy has also obtained large increase.
