What is the impact of refitting a diesel car into a natural gas vehicle?

Many owners with strong DIY ability always like to modify vehicles. They have begun to think about how to convert diesel cars into natural gas vehicles. But what will be the impact of retrofitting?

More environmentally friendly

Natural gas vehicles are converted to clean natural gas. After combustion, they only produce carbon dioxide and water, which is more environmentally friendly than burning diesel. In addition, the relevant departments are now very strict on the dehydration and desulfurization processes in the filling stations in the urban areas, which eliminates the corrosion of engines that are caused by the harmful chemical substances generated after natural gas burning. Another benefit of using natural gas is that it avoids the problem of engine carbon deposition caused by the use of diesel.

More fuel-efficient

Now that the price of gasoline is constantly rising, changing natural gas can help owners save more fuel. I think this is considered critical by many vehicle owners. However, one thing to note is that after the diesel vehicle has changed its natural gas, the problems caused by the modification may cause the manufacturers to fail; the rear-wheel springs need to be replaced with heavier springs; the trunk space is reduced; a one-time investment of several thousand yuan is also required. Before the specially modified personnel also made three programs: First, the engine replacement, that is, using the original engine replaced by a new natural gas engine. Take 350 horsepower as an example, the cost is about 100,000 yuan, this scheme is very good, the price is a little expensive; the second is retrofit: the engine performance is required to be good, in 2 years, the cost is about 40000 yuan; The third is the burning: that is in the engine After the speed reaches a certain speed, it automatically switches to natural gas. The replacement ratio is 30-40%, and the cost is about 40,000 yuan. It can be seen that there will be some economic costs to be refitted once, so if the original plant does not add natural gas, we do not recommend refitting because its pipes and computers are not the same as those assembled by oil companies on the production line. Will affect the body structure and computer settings, and put a gas tank behind the event of a rear-end accident in case of disastrous consequences.
