The automobile is a gasoline engine, and the turbine intake forcibly compresses the air, increasing the intake and improving the combustion efficiency. However, the fuel of natural gas vehicles is liquefied natural gas, which is unstable and explosive. If turbocharging is modified, excessive intake air may ignite natural gas, leading to deflagration or explosion.
In addition, natural gas vehicles do not need pressurized air intake during normal driving. Increasing the air intake will make the combustion more active, but it will damage the engine block and weaken the strength of the engine wall, which will easily lead to the danger of cylinder explosion.
Extended data:
Changing automobile oil to gas is a modification method to change the fuel type of motor vehicles. Refers to the process of converting the original fuel into natural gas.
The advantages of changing automobile oil to gas are: high economic benefit, good social benefit and high safety.
Application procedure of automobile oil to gas device

1, project application
2. Business license of the enterprise
3, automobile manufacturing or maintenance license
4. Bank credit certificate
5. Introduction materials on the basic situation of vehicle changing operation of enterprises:
(1) the modified vehicle source market forecast and analysis report of the location and city scope of the modified enterprise;
(2) List of production sites, main equipment and measuring instruments of the refitted enterprise;
(3) to guide the revision of post setting, number of personnel and professional qualifications;
