Of course, the most used natural gas models are still heavy trucks in the cargo transportation sector. Whether it is based on environmental considerations or economic considerations, more and more card-friends are turning their attention to natural gas models. At the same time, however, some of the card-friends felt that after changing the natural gas model, they always felt that the vehicle was underpowered, and even they couldn't wait to step the accelerator into the tank, but they still felt that the engine was weak. Adequate power and explosion resistance For drivers who are accustomed to using diesel engine models, the diesel car's power to get up and running quickly at the start of the car is very refreshing, and after switching to a natural gas model, it is also a throttle, and it always feels a bit slow. Therefore, they feel that natural gas engines are inferior to diesel engines. In fact, this is entirely due to the illusion caused by the different characteristics of the fuel used. There is no essential difference between the two in terms of power. Even natural gas engines have certain advantages. For example, China National Heavy Duty Truck uses the MC13 engine technology upgraded from the MT13 natural gas engine, its power level has reached the maximum power of 430 horsepower and the maximum torque of 1900 Nm, does not lag behind the torque output of diesel engines of the same level. And because natural gas has an octane rating of 130, it also has anti-riot performance that the diesel engine cannot match. In addition, what are the differences between natural gas engines and diesel engines? Different lighting methods Since the natural gas engine uses a natural gas ignition temperature of 650°C, it must be ignited by the spark plug and then drive the piston, which is similar to the gasoline engine's working principle. The ignition temperature of diesel is 220°C. Under the condition that the spark plug is not needed, the ambient temperature inside the cylinder exceeds the ignition temperature of diesel. Therefore, the diesel engine is compression-ignition type. And in terms of safety, the explosion limit of natural gas is much higher than that of diesel. Different combustion products With regard to the products of combustion, it must be known that natural gas as a clean energy source must have greater advantages in the emission of pollutants. The tail gas emitted after the start of a diesel engine contains a large amount of particulates, carbon monoxide, and hydrocarbons. Contamination of the environment, which has a stimulating effect on the human eye, eyes and respiratory tract trapping membrane. The emissions of natural gas engines are mainly water and carbon dioxide, and the tail gas does not contain sulfides and lead, and carbon monoxide and hydrocarbons are reduced by more than 60%. And natural gas heavy trucks are generally equipped with three-way catalytic converters, which can convert the harmful gases emitted through the oxidation and reduction into harmless carbon dioxide, water and nitrogen, further reducing pollution. Lower cost of use In addition, compared to diesel engines, natural gas is more easily mixed with air in the cylinder block of the engine, combustion is less likely to produce carbon deposition, and there is no disadvantage of diluting the lubricant in the diesel engine. Therefore, the zero in the engine block is zero. The wear of components is greatly reduced, the life of the engine and the service life of the lubricant are extended, and the maintenance cost of the vehicle is reduced. And in terms of cost, natural gas models also have a very big advantage. Take the Howard T7H natural gas model equipped with the MT13 engine as an example. According to the user's actual use situation, this model's 100 km gas consumption is only 32kg, compared to For diesel vehicles, the fuel cost per 100 kilometers is nearly 100 yuan, and the economic benefits are very good. LNG/CNG car complement each other At present, the natural gas engine uses fuel LNG LNG and CNG compressed natural gas, so the use of different natural gas engine models also have their own advantages and disadvantages, such as LNG LNG small size, but the price is relatively high, CNG compressed natural gas is relatively cheap and gas filling is also more convenient, but cruising range is not as good as LNG LNG models. Therefore, CNG CNG models are suitable for short-haul use, while LNG LNG models are more suitable for long-distance use. Golf Accessories Grand Dragon Sports Company Limited , https://www.golfyy.com

Energy saving and environmental protection costs low minutes to understand the natural gas engine
With the increasing stringency of environmental protection regulations, more and more cardmates have begun to use natural gas vehicles to run transportation. Actually, not only trucks , but also many areas of our lives use natural gas as a power source, such as gas turbines used by ocean-going freighters. , And we can often see the trunk with a gas tank by taxi, which is a modified natural gas engine .
