Liaoning eliminates standards from severely energy-consuming industries
Many Vehicle Sensors, sensor fault
judgment, should not only consider the the sensor itself, but should consider
the failure of the entire circuit. Therefore, in the search failure, in
addition to check sensor, but also check the wiring harness, connectors and
related circuit between the sensor and the electronic control unit.
Basic
Function:
The sensor refers to the physical
experience requirements, and according to certain rules to convert the input
signal of the device or devices available. Simply, sensor is the electricity
conversion device. The sensor is usually composed of non electric sensitive
element, conversion element and measurement circuit composed of three parts.
1), the sensitive element refers to the direct feeling (or response) by
measuring part will be measured by the sensing element and the measured is
converted into electricity or other quantity relationship. 2), the non
electricity converting element converts electrical parameters. 3), the
measuring circuit is the role of the input electrical parameters after
conversion element processing to convert the voltage, current or power
frequency can be measured, for display, record, control and processing part.

The air flow sensor is the inhaled air is
converted into electrical signals sent to the electronic control unit (ECU), as
one of the basic signal injection. According to measuring principle is
different, can be divided into rotary vane type air flow sensor, Carmen vortex
type air flow sensor, hot wire air flow sensor and the hot film air flow sensor
four the first two types. As the volume flow type, which is the quality of flow
type. Using hot wire air flow sensor and the hot film air flow sensor two. The
intake pressure sensor can measure the absolute pressure in the intake manifold
of the engine according to the load condition, and converted into electrical
signals and speed signals together into the computer, as determines the
injector fuel injection quantity basis. Is the widely used semiconductor
varistor type air pressure sensor. The solar term door position sensor mounted
on the day The valve, used to detect solar term door opening. It through the
linkage lever mechanism and the solar term door, which reflect the different
engine working conditions. The sensor can be put in different conditions after
the input detection engine electronic control unit (ECU), so as to control the
fuel injection quantity. It has three different types: switch contact type
solar term door position sensor linear, variable resistance type solar term
door position sensor, integrated solar term door position sensor, crankshaft
position sensor crankshaft position sensor crankshaft position sensor or crank
angle sensor, the sensor is the most important in computer controlled ignition
system, its function is to detect the TDC signals, crank angle signals and
engine speed signal, and input it the computer so that the computer can be in
the firing order of the cylinder from the best ignition time instruction.
Crankshaft position sensor has three types: electromagnetic pulse Crankshaft
position sensor, crankshaft position sensor Holzer effect, photoelectric effect
type crankshaft position sensor. The crankshaft position sensor of different
types, the control method and the control precision is different. The
crankshaft position sensor is installed on the crankshaft pulley or sprocket
side, some mounted on the front of the cam shaft, there are installed in the
distributor. The knock sensor installation in the engine block, the monitoring
of engine knock. The resonance and non resonance type two categories.
Static performance parameters:
The static performance parameters of the
sensor sensitivity refers to the ratio of the sensor output y and input X of
the steady state, and the increment of input or output x y increment ratio,
denoted by K k=dy/dx, the minimum resolution of change of the quantity being
measured in the measurement of force sensor can be detected within the
prescribed scope of the called the resolution. 3 the measuring range and the
range of the allowable error limit, the lower limit of the measured value to
the upper bound of the range between the called measurement range. The
linearity (nonlinear error) under specified conditions, the calibration curve
fitting and the percentage of the maximum deviation between the line sensor and
full-scale output value is called linearity or the nonlinear error. Hysteresis
refers to under the same operating conditions, the extent of the inconsistency
and anti stroke characteristic positive stroke characteristics of sensor. The
repeatability reproducibility refers to the same working conditions, The
inconsistency of the input in the same direction in the whole measuring range
change continuously in multiple characteristic curve. The income of zero drift
and temperature drift of sensor without input or to another value, at regular
intervals, the input value of percentage deviation from the maximum deviation
of the original value and the full range of zero drift. When the temperature
rise of 1 degrees Celsius, the maximum deviation of the sensor output value and
the full range of percentage, called the temperature drift.

In the total final energy consumption in Liaoning, industrial energy consumption exceeds 80%, of which metallurgy, petrochemical, and power industries account for 77.8% of all industrial energy consumption. In the face of tremendous pressure, Liaoning has adopted a "high-pressure" trend to eliminate backward production capacity. On May 27 of this year, the province issued implementation opinions on the elimination of backward production capacity, and large-scale elimination of backward production capacities in 14 key industries including steel, coke, calcium carbide, chemical fiber, and electric power, as well as the 14 key industries. The outdated production capacity elimination standards and implementation deadlines have been set. According to the requirements of the process, the elimination of backward production capacity in some industries was completed before the end of this year, and some industries were completed in the next two years.
In order to ensure the realization of the “Eleventh Five-Year Plan†energy-saving and emission-reduction targets, the Liaoning Provincial Government issued a notice on July 12 requesting the strengthening of energy-saving and consumption-reduction management in key industries such as electricity, steel, and petrochemical industries. For areas where it is difficult to complete the task of reducing chemical oxygen demand, heavy pollution industries such as batch printing, dyeing, papermaking, chemical industry, and leather making are implemented. Projects that have not passed the environmental impact assessment, energy conservation review, and land prequalification will not be allowed to start construction. For projects that are under non-compliance with regulations, they must be ordered to stop construction. Financial institutions will not be permitted to issue loans. Proper measures must be taken to protect the credit assets that have been issued. Safety; For projects that are built in violation of regulations, they must be ordered to stop production. Financial institutions must not add any form of credit support. The relevant departments must stop the supply of electricity.
At the same time, the province took the lead from the source and formulated the “Guiding Catalog of Industrial Energy Efficiency in Liaoning Provinceâ€, which quantifies the energy consumption limit indicators for 39 major industries, 191 medium-sized industries, 133 products, and 30 energy-using equipment. Provincial and municipal energy conservation and emission reduction authorities organize the main basis for evaluating energy consumption of fixed asset investment projects. The projects with resource and energy consumption higher than the industry average and the energy consumption limits of key energy products and major equipment will not be approved. The establishment of this energy efficiency threshold establishes strong technical support for the full implementation of the “assessment†system for fixed asset investment projects in order to improve the structure and quality of industrial energy use.
In order to encourage enterprises to destroy the backward equipment and transform production, in 2008, Liaoning Province issued 21 million yuan of out-of-pocket special incentive funds for 21 enterprises, and eliminated 552 tons of backward production capacity. In the same year, there were 37 enterprises in the province, which received 251.45 million yuan of funds for the elimination of backward production capacity by the central government, and eliminated 9,038,900 tons of backward production capacity. In 2009, the province re-arranged special funds to provide subsidies and rewards for the elimination of backward production capacity enterprises. In the same year, there were 24 companies that received central government financial incentives to phase out outdated production facilities with 17.917 million yuan of backward production capacity of 3.510 million tons.
According to the person in charge of the Economic and Information Technology Commission of Liaoning Province, Liaoning Province has stricter standards for the elimination of certain industries than the national standards. In addition, Liaoning Province has also determined that some countries do not provide for the elimination of backward production capacity products, such as magnesia products.
The person in charge told the reporter that Liaoning accelerated the elimination of backward production capacity. First, it raised the threshold and imposed a strict access system for high-energy-consuming and high-pollution enterprises. Second, it implemented the differential electricity price system and increased the rate of tariff increase for backward production capacity; The preferential taxation policies for the comprehensive utilization of resources enjoyed by energy-consuming and highly polluting enterprises; in addition, the principle of equal replacement or decrement replacement for new production capacity and elimination of outdated production capacity in industries with overcapacity; and at the same time, give full play to the guiding role of financial funds. Mobilize the enthusiasm of enterprises, encourage enterprises to destroy and destroy backward equipment and transfer production, properly deal with issues such as assets and debts, personnel placement, and effectively safeguard social stability.
