Characteristics and common usage precautions of CNG conversion kits

. Core Features of CNG Conversion Kit

①Power and energy efficiency performance

The new fifth-generation sequential direct injection kit adopts a single ECU intelligent control system, enabling cylinder-specific timing and quantitative gas supply. This significantly mitigates the power loss and backfire issues associated with traditional modifications. With more precise gas distribution, combustion efficiency is notably enhanced, effectively reducing vehicle operating costs. Given that natural gas is only half the price of gasoline in the market, its long-term economic benefits are outstanding.

②Compatibility and adaptability

The mainstream electronic control kit is compatible with most mainstream gasoline vehicle models worldwide. The optimized software and hardware solutions have addressed the compatibility shortcomings of older products, allowing it to perfectly match electronic fuel injection gasoline engines equipped with oxygen sensors and three-way catalytic converters. The compatibility scenarios cover various vehicle types, including private cars and commercial vehicles.

③Environmental protection and safety advantages

Equipped with a dual OBD emission detection system, the harmful exhaust gases such as carbon monoxide and particulate matter after combustion are significantly reduced, meeting the requirements of low-carbon travel. The kit comes with multiple protective components such as safety valves, pressure/temperature sensors, etc. With standardized operation, it can ensure stable operation of the gas system, prevent carbon buildup during natural gas combustion, reduce internal engine wear, and extend the service life of components.

④User experience optimization

The oil-gas switching process is smooth and seamless, with some models equipped with a buzzer alert function that actively warns in case of low gas pressure or system malfunction. The interface design is standardized, making installation convenient and daily maintenance less challenging.

II. Common key usage precautions

①Daily operation specifications

Before driving, it is necessary to check whether there are leaks in the pipelines and connectors. Soap water can be used to apply to the connectors to identify any bubbling or air leaks. Fuel switching should be completed under high-speed engine operating conditions, avoiding congested roads, uphill and downhill driving, and turning to prevent engine stalling. More than 10L of gasoline should be reserved in the fuel tank, and every 3000km of driving, the vehicle should be switched to gasoline for 50km to avoid long-term idling and failure of the gasoline system.

②Regular maintenance requirements

Open the drain outlet monthly to clean CNG deposits, and clean the mixer and blow-off pipeline filter every 2000km; the national standard CNG cylinders must undergo mandatory inspections: the first inspection after 3 years of use, the second inspection after 5 years, and an annual inspection after 6 years. Meanwhile, regularly inspect the cylinder protective rubber gasket, and replace it immediately if it is aged or damaged.

③Safety and emergency response

During the break-in period of a new vehicle (within 3000km), CNG is prohibited and must be operated by a professionally trained driver. The vehicle should be parked in a shady and ventilated area, away from sources of fire and heat. If a leak occurs while driving, immediately stop the vehicle, turn off the power and the manual valve of the gas cylinder, isolate the source of ignition, and then use gasoline to drive to a professional service station for maintenance. In case of a fire, immediately close the cylinder valve, use a dry powder fire extinguisher to extinguish the fire, and cool down the cylinder.

④Long-term parking requirements

For vehicles that have been idle for a long time, it is necessary to completely evacuate the residual gas from the pipes and pressure reducers to avoid potential safety hazards caused by residual gas.
