We have learned some of the deficiencies of diesel vehicles, such as serious environmental pollution, loud noise from vehicles and so on. From a technical point of view, we can convert diesel cars into natural gas-powered cars. This is a viable option, and some vehicles have already been modified, such as garbage trucks that are common in the city. We analyze the issue of changing diesel vehicles to natural gas vehicles from the following aspects. First, the content that needs to be modified. The main contents of replacing a diesel car into a natural gas vehicle include two aspects. One is a fuel supply system and the other is an engine system. The fuel supply system needs to replace the original tank with a natural gas bottle (compression or liquefaction), and to replace the diesel engine with a natural gas engine. This method of replacing two parts is often used in the past. With the continuous development of the technology for the conversion of diesel cars, we can now use the engine replacement method to achieve the modification of diesel vehicles. The specific approach is to replace the pistons, piston rings and cylinder heads of newly installed engines, and then directly replace the engine. This method is relatively simple and flexible, and the replacement efficiency is also high. Second, the safety of the converted car. The safety of refitted natural gas vehicles is a matter of greatest concern to everyone. For this we can compare these aspects. Containers for holding fuel: The fuel tank contains diesel fuel. The ignition point of diesel fuel is low. Once the temperature of a car engine exceeds the ignition point of diesel fuel, it can easily cause explosions, and the ignition point of natural gas is much higher. The density of natural gas is lower than that of diesel, and it is not easy to ignite. The density of diesel is large and volatile and easily ignites. Third, the economical and practicality of the retrofitted vehicles. The converted natural gas combustion emissions are more pure and less polluting to the atmosphere. Moreover, the combustion efficiency of natural gas is high, which can save more fuel costs than diesel vehicles. In addition, the use of natural gas in automobiles can reduce the loss of vehicles, and the cost of the car, whether it is in maintenance or use of lubricants, is much lower than that of diesel vehicles. The economic utility of the converted natural gas vehicle is better. These machines are mainly used for construction,bridge, tower and other steel structure in the connection plate drilling,it can also be used for boiler, petrochemical, refrigeration and other industries tube sheet, baffle and flange drilling and milti-holes drilling in the falat plate, parts drilling.
