China CNG LPG ECU Company Introduces The Engine Usage Process

In a short time after the engine is started, the generator will charge the battery with a large current, generally about 15 amperes, and after a few minutes, the charging current gradually tends to zero. If the charging current is greater than 20 amperes, it does not decrease after a few minutes, indicating that the regulator voltage regulation is too high. At this time, check the polished contacts and adjust the tightness of the spring. This fault is mainly due to excessive spring tensionbig. The spring should be relaxed to reduce the tension.

If the ammeter indicates discharge, first check whether there is a short circuit in the line. If there is a short circuit, remove it immediately. If the circuit is intact, the cause of the ammeter discharge is inside the regulator. At this time, check and polish the low-speed contacts, and then disconnect the high-speed contacts. If the adjustment voltage is still too low after inspection and adjustment, the tension of the spring can be adjusted to increase the tension of the spring to increase the adjustment voltage. The gap of the high-voltage contact is generally 0.30 mm.

The swing of the ammeter pointer is mostly caused by the poor operation of the regulator. At this time, check the clean contacts and check whether the yoke and spring are scratched. If there is any scratch, repair it in time. Also pay attention to check the assembly of the adjuster armature and iron core and the gap between them. If it is found that the assembly of the armature and the iron core does not meet the standard, it should be reassembled; if the gap does not meet the standard, the gap should be adjusted. title the gap between the iron and the iron core is 1 mm.

China CNG LPG ECU Company introduced that if it is difficult to adjust the charging current due to a regulator failure, the main reason should be to check the assembly of the contacts and the armature. If there is no abnormality in the contacts, it is generally affirmed that the armature is improperly assembled or has failed. If the armature does not improve after reinstallation, it should be replaced with a new one. This is mainly to improve the sensitivity of the armature when it vibrates.

Timing Advance Processor Factory Introduces The Use Process Of Lng

Timing Advance Processor Factory introduced that LNG has undergone a series of special treatments (dealkylation, dehydration, desulfurization and purification), then cooled to -162°C by cryogenic technology, and stored in a container in liquid form under low temperature and normal pressure. It is widely used as a vehicle fuel for heavy trucks, large transportation vehicles and buses, and LNG has the following characteristics.

1. The volume of liquefied natural gas is 625 times smaller than that of natural gas of the same quality, so it is very convenient to transport liquefied natural gas to places without natural gas by car, train, or ship. In international trade, 25% of natural gas is transported in liquids.

2. LNG storage efficiency is high, occupies less area, and low investment. Ten cubic meters of LNG can supply 10,000 households with daily gas.

3. Compared with gasoline, LNG has the advantages of high octane number, good anti-knock performance, long engine life, low fuel cost, and good environmental performance. Hydrocarbons and nitrogen oxides can be reduced by 72% and 39%, respectively, and sulfur oxides and lead can be reduced to zero.

4. With high latent heat of vaporization, the cold energy in the liquefaction process can be recycled.

5. After vaporization, the density is very low, only about half of air. If LNG leaks slightly, it will spread immediately, thereby reducing the possibility of explosion.

6. Liquefied natural gas is a good clean fuel. Because of its pure composition and complete combustion, it produces carbon dioxide and water after combustion, which is beneficial to protect the environment and reduce urban pollution. After natural gas is treated at low temperature, the sulfur components are precipitated and separated in solid form, which is cleaner than other fuels, and emits lower greenhouse gas when burned, which is a kind of "green" energy.

Cng Lpg Ecu Factory Introduces The Maintenance Rules Of Electronically Controlled Natural Gas Lng

Cng Lpg Ecu Factory introduces the precautions for the use and maintenance of electronically controlled natural gas LNG:

1. During inspection and maintenance, it is strictly forbidden to knock or hit gas cylinders, pressure reducing valves, pipelines, and other valve bodies; when troubleshooting the gas supply system, the main gas valve and all cylinder gas valves must be closed before the pipeline can be carried out. Disassembly, it is strictly forbidden to work under pressure;

2. Electronically controlled natural gas LNG maintenance personnel must undergo professional training. Persons who are unlicensed or have not participated in the training are prohibited from operating and maintaining electronically controlled natural gas LNG and CNG vehicles to avoid danger.

3. To check and repair any malfunction of the electric control system, turn off the ignition switch before plugging and unplugging the plug to avoid burning the sensor electric control unit and other electrical equipment due to self-inductance and mutual induction electromotive force;

4. Whether it is a driver or a maintenance worker, always pay attention to the gas storage and liquid gas leakage alarm device of the electronically controlled natural gas vehicle. If there is a failure, it should immediately stop the maintenance.

5. When the pipeline parts on the gas cylinder body need to be replaced in actual maintenance, the pipeline gas cylinder should be emptied and the pressure should be relieved. When the pressure is relieved, a suitable location should be selected according to the safety protection measures.

6. For gas cylinders with a storage period of more than five days, it is easy to store the liquid in the cylinder at 10L, keep the cylinder in a cold state, and close all valves.

Cng Lpg Ecu Supplier Introduces The Adjustment Method Of Gas Pressure Regulator

Cng Lpg Ecu Supplier introduces how to adjust the gas pressure regulator:

1. Set the pressure, follow the principle from high to low, and proceed one by one step by step, namely: cut off the pressure-relieve the pressure-work pressure.

2. After the pressure is set, check its closing pressure to verify its performance and whether it reaches the required value.

3. The outlet valve can be opened only after the pressure setting meets the requirements, and the outlet valve should not be opened before that to prevent accidents.

4. Precise instruments should be protected to prevent large pressure fluctuations from damaging the instruments.

5. During the debugging of the pressure regulating equipment, if uninterrupted air supply is required. The pressure should be manually controlled through the bypass first, and the pressure regulating valve should be controlled by one hand. The pressure gauge should be held in one hand, and the pressure change should be observed at all times to maintain the outlet pressure at the required level. Within the pressure range, after the pressure setting of the pressure regulator is completed, slowly open the pressure regulator outlet valve, and then close the bypass valves after the pressure regulator normally supplies air.

6. If the pressure regulator adopts 2+0 one open and one closed type, both circuits need to be debugged. Open one and close one (standby). The air pressure between the inlet and outlet valves should be vented in the standby circuit to avoid the pressure regulator film and The spring is compressed, causing fatigue.

7. If the pressure regulator port uses two channels to automatically switch the air supply, the pressure parameters need to be set according to the main and secondary channels, and then the two inlet and outlet valves are kept fully open. Automatic switching has higher requirements for the performance of the regulator, and it is generally stable. Pressure accuracy ≤2.5%. It is advisable to close the accuracy ≤10.

8. Series monitoring and voltage regulator debugging The series monitoring of the voltage regulator mostly adopts the form of passive monitoring, that is, the monitoring voltage regulator is in a fully open state.

(1) First check whether the pressure signals of the two voltage regulators (or pilots) are correct. If the pressure signal tubes are all connected after the working voltage regulator, it is a correct connection.

(2) Press the pressure regulating springs of the two regulators to the tightest rim of the pressure regulating spring of the front regulator (monitoring regulator) to make the pressure of the subsequent stage to the cut-off pressure, and debug the cut-off valve.

(3) Debug the relief valve.

(4) Loosen the pressure regulating spring of the front pressure regulator (monitoring pressure regulator) again to bring the intermediate pressure to about +10% of the set value of the outlet pressure.

(5) After loosening the pressure regulating spring of the pressure regulator (working pressure regulator). Bring the back pressure to the set value of outlet pressure (at this time, the intermediate pressure will rise to equal to the inlet pressure).

9. After the adjustment of the regulator is completed, use foaming agent to check the connections and the loose places during the adjustment process for gas leaks.
