Glow plug temperature control method technology for reducing emissions from Diesel Engines

A glow plug control method is used to reduce emissions from diesel engine exhaust, waste gas. The excessive oxygen used much in the exhaust stream O2(), CO(carbon monoxide oxidation CO2()carbon dioxide ), and fire-damp HC( )is oxidized H2O(water )and CO2. There is a 90% reduction in visible particles (soot ). The precise control of the activation of a glow plug makes it possible to be effective in emission reduction, by the activation time. The hold time is dependent on the combustion chamber temperature. Each glow plug can be determined during the average voltage, separately by the activation time. Identification is the acceleration period of the motor, according to a glow plug control method. The combustion efficiency is improved, and in some cases, the overall efficiency of the engine is improved. In addition, the activation of preheating of the glow plugs, is to establish a catalytic combustion effect. Accordingly, it is possible to reduce emissions, when the combustion efficiency is low, for example, during acceleration period, can assert the reduction of the exhaust gas that is discharged.

When a glow plug is activated according to the algorithm, and when the motor, according to the new European driving cycle (New European Drive Cycle referred to as urban driving cycle NEDC) (Urban Drive Cycles called UDC) is driven, the glow plug activation is going to increase. The algorithm about the graph. The diagram shows the glow plug square wave connection, disconnected signal 36, crank rotating speed signal 37, fuel in the signal 38 and a cooling water temperature signal 39. These signals are respectively measured by voltage and each of speed, each stroke cubic millimeter degree Celsius. A time scale to by the second.

The schematic diagram shown by a cold start of diesel engine about after 69 second cold start of diesel engine, about 690 second of the window. According to the temperature signal 39, cooling water temperature is raised to similar continuously logarithmic mode until nearly is about 60 a DEG c final temperature. After activation, glow plugs algorithm is control by substrate applications, and maintaining the connection activation time continuously 41. In the case UDC, the activation time activation type 40 due to the cycle of the stage UDC. With the crankshaft rotation signal 37, this may be seen particularly. In the figure example, The glow plugs; 90 the second activation time. The crankshaft rotation signal maximum 39 reflected three speed stages UDC. In the schematic diagram and style of three maximum value complex almost four times, so it means that the schematic diagram almost covers four UD cycles. A glow plug activated start with the stage UDC. In addition, the idle speed of motor in reduced between stages. The crankshaft rotation signal cycle 37 also in the fuel is in a signal type 38 to be reflected. However, the fuel in the signal 38 in a state by varying the combustion chamber to be modified. The fuel consumption is reduced, and almost disappears between the first and third UDC stage before the peak value. In the second UDC stage before the peak value. In addition, during, when shifting, load to cause the fuel consumption is reduced to a very low value, before the fuel in the signal negative peaks not to stop. The display has a 4 second glow plug by the algorithm, because the simplified caused activated font schematic diagram. Based on the algorithm of the simplification, when the crankshaft rotation speed is higher than a minimum time of the threshold value continuously determination, the glow plug is activated. When the crankshaft rotation speed is lower than the threshold value, the glow plug is deactivated. According to the algorithm, a glow plug UDC is only activated during a secondphase. In the first stage, the UDC glow plug due to low - speed, but is not activated, and in the third UDC stage, a glow plug as a result of the shift, but is not activated. The result is a glow plug is activated continues 3×20 = 60 second.

According to the application of a glow plug control method and surrounding the second emission control method of a comparison of CO. In the figure 5, shows the original emission CO from the engine and has shown 6 clean discharge CO after catalyst. In the figure diagram 5 has shown 50 speed curve, the first original discharge curve 51 and a second original discharge curve 52. The rod is km/h and number of CO/second. The speed profile includes four UD cycles, each UD cycle has a first stage respectively 53, the second stage 54 and a third stage 55. The first original discharge curve 51 52 is mainly characterized in that the emission peak value and a second original discharge curve difference, from the discharge of the first original discharge curve is low. These differences 56 are represented by a pitch.

The graph 5 the first original discharge curve 51 `is characterized in that the emission peak value and a second original discharge curve 52 `difference, from the discharge of the first original discharge curve is low. In addition, during a second UD cycle, the discharge of the first discharge curve 51 `is also lower. In a word, compared with the second control method, when a glow plug by the method according to the application is heated, the CO a significant reduction in emission. The result believes that although also according to the second control method, a glow plug UD during a second phase of the cycle is activated. The graph and 6 5 are shown generally as well as the combustion chamber is the final temperature along with the cooling water from, the original emission is reduced. The graph 6 also show high - temperature along with the combustion chamber, the efficiency of the catalyst is obviously improved. For NOx, 6 5 is also effective for map and simulation results.
