1. Impact of market demand
 The price of on-board hydrogen oxygen machine is greatly affected by the market demand. First of all, there are differences in the functions and performance of different brands of on-board oxyhydrogen machines. Therefore, brand awareness and product reputation will directly affect the price level. Famous brand products usually have higher prices, while new brands may attract consumers with low price strategies in order to open the market. Secondly, the market demand of vehicle mounted oxyhydrogen machine will also affect the price. When the market demand is high and the supply exceeds the demand, the price will rise; When the market demand is low, the price may decline.
 In addition, the function and performance level of the on-board hydrogen oxygen machine are also important factors affecting the price. Some high-end vehicle mounted oxyhydrogen machines have more functions and more advanced technology, so the price is relatively high. However, some ordinary vehicle mounted oxyhydrogen machines are relatively simple in function and affordable.
 2. Impact of technology costs
 The price of on-board hydrogen oxygen machine cannot be formed without consideration of technical cost. First of all, the production of vehicle mounted hydrogen oxygen machine requires the purchase of special production equipment, and the price of these equipment directly affects the cost of the product. The high cost of production equipment will increase the price of on-board hydrogen oxygen machine; On the contrary, the lower cost of production equipment will reduce the price of vehicle mounted oxyhydrogen machine.
 Secondly, the material cost of vehicle mounted oxyhydrogen machine is also an important factor affecting the price. The price of high-quality materials is higher, while the price of some common materials is relatively cheap, which will directly affect the cost and final price of the vehicle mounted hydrogen oxygen machine.
 In addition, the production of vehicle mounted hydrogen oxygen machine also requires certain labor costs, including staff salaries, training costs, etc. The increase of labor cost will also make the price of on-board hydrogen oxygen machine rise.
 3. Impact of market competition
 Market competition is one of the important factors for the price change of vehicle mounted oxyhydrogen engines. When there are more competitors in a market, the price is often more transparent and reasonable. In the highly competitive market, manufacturers will attract consumers by providing more competitive prices, which will lead to a decline in the price of on-board hydrogen and oxygen machines.
 In addition, market positioning is also one of the important factors affecting prices. The pricing strategies of vehicle mounted oxyhydrogen engines in different market positions are different. The price in the high-end market is usually high, while the price in the low-end market is relatively low. The market positioning of vehicle mounted hydrogen oxygen machine is closely related to its product positioning and brand image.
 The supply and demand relationship of the market will also directly affect the price change of the on-board hydrogen oxygen machine. When market supply exceeds demand, manufacturers may stimulate market demand by reducing prices in order to sell products; When market supply falls short of demand, prices may rise.
 4. Consumer impact
 Consumers also have a certain impact on the price of on-board hydrogen and oxygen machines. First, consumers' sensitivity to price will directly affect their purchase decisions. Some consumers are more sensitive to the price. They will pay more attention to the price change of the vehicle mounted hydrogen oxygen machine, and the fluctuation of the price will have a greater impact on their purchase behavior.
 Secondly, the budget constraints of consumers will also affect their preference for the price of on-board hydrogen oxygen machines. Some consumers have certain restrictions on budget, and they will choose the vehicle mounted oxyhydrogen machine with relatively low price.
 Consumer psychology will also have an impact on the price of on-board hydrogen and oxygen machines. Some consumers think that the quality of high priced products is more reliable, and they may buy relatively expensive vehicle mounted oxyhydrogen machines; While some consumers pay more attention to cost performance, they will choose the vehicle mounted oxyhydrogen machine with relatively low price but reasonable function and performance.
