Heavy-duty diesel vehicles use CNG fuel
2021年4月28日 日常When we think about emissions, we usually think about our vehicles and the new wave of personal electric vehicles. The reality is that heavy-duty vehicles used for the transportation of goods and passengers produce far more emissions and use a lot more fuel than personal vehicles.
We can make a bigger impact in reducing emissions by replacing heavy-duty diesel vehicles, especially those that use a lot of fuel. We can also impact more lives by reducing emissions from the transit and school buses and protect the health and our fragile environment.
While some nations have already taken a leap, the USA is now accelerating its move to natural gas heavy-duty trucks and transit buses. In fact with Cummins-Westport’s North America launch of the near-zero NOx ISL-G series engines, CNG/ LNG now offers the cleanest way to go for medium and heavy-duty applications.
The largest limitations have been that our duty cycles are typically more demanding in terms of variations of temperature with deep negatives like -40F in the north to high 100’s in the deserts of Arizona and New Mexico. The current fuel system designs also limit the amount of recoverable fuel from the tanks to about 350-400 psi tank pressure. Further, no regulatory system in the market was certified to the nationally recognized ANSI NGV3.1 standard. Existing systems also compromise the reliability of vehicles with poor filtration of contaminants and designs that include materials such as Buna, susceptible to failure in the local operating conditions.

Analyze whether CNG vehicles are safe
2021年4月21日 日常In the promotion of natural gas vehicles, people are worried about the safety of natural gas vehicles, especially CNG vehicles. This is a misunderstanding.
Of course, natural gas is an explosive gas, but the explosion of natural gas is conditional. After adopting a series of safety measures, after understanding its characteristics, natural gas vehicles can be used safely.
First, judging from the characteristics of the fuel itself, the ignition point of natural gas is generally above 650°C, while the ignition point of gasoline is 427°C. Natural gas is 200°C higher than gasoline, which means that natural gas is not as easy to ignite as gasoline.
Second, the volume limit of natural gas burning in air is 5% to 15%, while gasoline is 1% to 7%. In other words, a gasoline concentration of 1% in the atmosphere is more prone to fire. Natural gas is much better than gasoline because it must accumulate to 5% before reaching the lower combustion limit.
More importantly, natural gas is lighter than air, and its density is only 55% of air. If it leaks slightly, it will easily diffuse into the atmosphere without reaching the low combustion limit.
When in use, it is necessary to add odorants to the natural gas to improve the early detection ability of natural gas leakage, so as to take preventive measures.
Even if the proportion of natural gas in the air reaches the explosive limit, if there is no source of fire, there will be no explosion. Therefore, fireworks must be strictly prohibited in places where natural gas is stored.
Jiaxing Lineng Autogas Equipment Co., Ltd. reminds you that if you have modified a natural gas vehicle, you must check it on time to avoid gas leaks. If you are still hesitating whether to modify a natural gas vehicle, you can consult our related questions, and we will give you the most professional answer.

Natural gas vehicles are vehicles powered by natural gas as fuel. Natural gas refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in the formation. Its main component is CH4, usually containing other alkanes, such as ethane, propane, butane, etc., and sometimes also contains a small amount of CO2, nitrogen, H2S and helium.
As early as the 1960s, natural gas vehicles have emerged in the field of road transportation in China, and they have developed to a considerable scale after nearly 60 years. At present, the general trend of promoting environmental protection and improving the energy consumption structure is that natural gas vehicles, as a kind of clean energy vehicle, are bound to play a more important role. Natural gas vehicles will improve the environment together with new energy vehicles and replace a large amount of gasoline and diesel consumption, indirectly reducing the degree of dependence on foreign oil.
As of the end of 2017, the number of natural gas vehicles in China reached 6.08 million, of which the number of compressed natural gas vehicles reached 5.73 million, and the number of LNG vehicles reached 350,000. The number of natural gas filling stations has reached 8,400, of which the number of compressed natural gas filling stations has reached 5,300, and the number of liquefied natural gas filling stations has reached 3,100. These six data currently rank first in the world. From the overall scale, the development of natural gas vehicles in China is already at the forefront of the world.

Whether it is a compressed natural gas vehicle or an LNG vehicle, the technology in design, manufacturing, use, maintenance and supervision has been very mature. In particular, CNG cars have withstood the test of several life cycles from commissioning to scrapping. Proved its technical maturity. For another example, the mixed combustion of natural gas and diesel can replace 85% of diesel, and if methanol is mixed with diesel, the replacement ratio is less than 50%.
As more and more areas are covered by the more reasonable "oil and gas price ratio" of 0.6:1 and below, most of the owners of natural gas vehicles can obtain significant economic benefits. For example, in many places, LNG heavy trucks can save 10,000 yuan in fuel costs for every 10,000 kilometers, which can save more than 100,000 yuan a year, and can recover the cost of buying a car in that year compared with diesel vehicles.

Natural gas is safe and environmentally friendly. It has been vigorously promoted by various countries. It has the following three advantages and has been loved by car owners.
1. The economic benefits are good. Natural gas has good thermal efficiency and sufficient combustion. It is almost difficult to produce carbon deposits in the engine. It has good anti-knock performance and does not dilute the lubricating oil, thus greatly prolonging the life of the engine. Reduce the occurrence of burning oil.
2. The social and economic benefits are high. Compared with gasoline, natural gas has very little loss during the preparation process, and almost only emits carbon dioxide and water, which can be regarded as a new energy vehicle.
3. High safety. Gasoline vehicles are prone to spontaneous combustion and explosion accidents, but LPG vehicles are different. Leakage is quickly discharged outdoors, and the seal is tight enough. Unless extreme conditions are encountered, explosion accidents are difficult to occur.

The function of the timing advance processor: The electronic timing advance processor can be installed on 3-4-5-6 and 8-cylinder cars equipped with coil ignition systems and distributors. It can automatically adjust the lead time, improve performance, reduce consumption and "backfire" risk.
Installation and debugging of the timing advance processor: 1. A connector used to connect the processor and the phase sensor. Only applicable to certain vehicles. 2. The connector used to connect the processor and the TDP sensor interface cable.
The design of the management module of the timing advance processor: The design of the timer management module is based on the static array method. Use an array of timer nodes to store all timing requests, and each item in the array represents an available timer node. Each timer node has a status item, which indicates that the timer is in idle, in use or overflow state. The timing value of the timer and the message to be sent after the timer expires are also stored in the timer node, so that one hardware timer can be used to provide users with multiple software timers.
Timing Advance Processor driver: The software timer driver is provided by the hardware timer. In the hardware timer interrupt, the value of the auxiliary timer is first reduced by 1. If the auxiliary timer value is 0, it means that the timer with the smallest timing value has expired. The corresponding message should be sent to the user task, the node should be placed in an idle state, and the timing value of other nodes should be recalculated, and the smallest timing value should be found at the same time Node, update the auxiliary timer.
