·Beijing-Tianjin-Hebei: Three places will promote the implementation of motor vehicle V emission standards this year

The Capital Standardization Committee reviewed and approved the "2016 Beijing Standardization Implementation Points" on the 21st. The Beijing-Tianjin-Hebei Geological Supervision Bureau stated at the review meeting that this year will promote the unified implementation of motor vehicle V emission standards.
The upgrading of refined oil quality has a positive effect on the prevention and control of atmospheric pollution. Zhao Changshan, director of the Beijing Municipal Bureau of Quality Supervision, said that this year, Beijing, Tianjin and Hebei will promote the implementation of air pollutant emission standards such as motor vehicle V emission standards, organize and prepare for the sixth phase of local fuel fuel standards, and strive to release air pollution. Comprehensive emission standards, adhesives and volatile organic compounds content limits for architectural coatings.
The Beijing-Tianjin-Hebei geological supervision department has now established a good cooperation mechanism to formulate local standards for the three places in environmental protection, transportation, and pension. The Beijing-Tianjin-Hebei geological supervision department said that at present, these local standards are mostly recommended standards. In the future, Beijing-Tianjin-Hebei will gradually unify emission standards, unified supervision and enforcement, and do a good job in joint prevention and control of the atmosphere.
It is understood that this year, the Beijing Municipal Bureau of Quality Supervision will comprehensively carry out the integration and streamlining of mandatory local standards, and strive to upgrade a batch, transform a batch, and abolish a number of mandatory local standards. In addition to the special areas stipulated in laws and regulations and the State Council's reform plan, Beijing no longer sets new standards and issues mandatory local standards.

Ignition System is an important component of gasoline engine, the performance of the ignition system is good or not to the engine power, fuel consumption and exhaust pollution and so on. All the equipment capable of producing an electric spark between two electrodes of the spark plug is called the engine ignition system. It is usually composed of battery, generator, distributor, ignition coil and spark plug.


When the gasoline engine compresses close to the top stop, the combustible mixture is ignited by the spark plug, which burns the external work, for which the spark plug is installed in the combustion chamber of the petrol engine. The function of the ignition system is to generate an electrical spark of sufficient energy between the two electrodes of the spark plug at timed intervals in accordance with the working order of the cylinders.


Electronic ignition system is generally divided into the following 3 categories:

(1) The ignition system consisting of electromagnetic, infrared or hall components is called Non-contact Point firearm, and the amplifying circuit is divided into transistor circuit and capacitor discharge circuit

(2) The ECU controlled ignition system is determined by the ECU microprocessor according to the crankshaft angle sensor signal to determine the ignition moment, so it does not break the electrical apparatus, only the distributor, according to the ECU to send the signal direct control ignition coil primary circuit Electronic.

(3) Non-distributor ignition system (distributor-less ignition) is currently the most advanced ignition system, the crankshaft sensor sent not only the ignition moment signal, but also the cylinder identification signal, so that the ignition system to the specified cylinder at a specified time to send the ignition signal, This requires a separate ignition coil per cylinder, but if it is six cylinder machine then 1, 6 cylinders, 2, 5 cylinders and 3, 4 cylinders are shared with a single point of the FireWire coil, that is, a total of three ignition coils, obviously every point in the ignition coil, there is always a cylinder is empty ignition, detection should be noted this point.
