How to improve the power of oil to gas vehicles

It is a common phenomenon for the power of cars to decrease after switching from gasoline to gas. The following methods can be used to improve power:

Optimize gas system

1. Adjust the jet volume and injection time: - Principle: The mixing ratio of natural gas and air is crucial for combustion efficiency and power output. Under different operating conditions, the amount of gas required by the engine varies. Accurately adjusting the injection amount and injection time can allow the gas to burn fully in the cylinder and release maximum energy- Operation: Use professional natural gas debugging equipment to connect the vehicle's gas control system. Fine tune the injection volume and injection time based on parameters such as engine speed and load. For example, when the engine is running at low speeds and under low loads, reduce the amount of air injection appropriately; At high speeds and high loads, increase the injection volume and optimize the injection time to ensure that the gas and air are evenly mixed and fully burned in the cylinder, thereby improving power.

2. Upgrade gas injection device: - Principle: The original gas injection device may not be specifically designed for the characteristics of natural gas, and its performance may be limited. High performance injection devices can more accurately control gas injection, improve the uniformity and atomization effect of gas and air mixing, thereby enhancing combustion efficiency and power- Operation: Upgrade the original vehicle's single point injection system to a multi-point injection system. The multi-point injection system can independently inject gas at the intake manifold of each cylinder. Compared with single point injection, it can more accurately control the gas supply of each cylinder, making combustion more complete and significantly improving power. For example, some car models can increase their power by 10% -20% after being modified with a multi-point injection system.

3. Inspection and maintenance of pressure reducing valve: - Principle: The function of a pressure reducing valve is to reduce the pressure of high-pressure natural gas to an appropriate pressure for engine use. If the pressure reducing valve is not working properly, such as excessive pressure reduction or unstable pressure, it will cause poor gas supply and affect engine power- Operation: Regularly check the working status of the pressure reducing valve to see if there are any blockages, leaks, or abnormal pressure regulation. Clean the filter inside the pressure reducing valve to prevent impurities from blocking it; Check if the membrane is damaged and replace it promptly if there are any issues. At the same time, according to the vehicle manual, adjust the output pressure of the pressure reducing valve to a suitable range to ensure stable gas supply, meet the needs of the engine under different operating conditions, and maintain good power output. Improving engine related components 1. Replacing high-performance spark plugs: - Principle: The ignition performance of spark plugs directly affects the combustion speed and effectiveness of gas. High performance spark plugs can generate stronger ignition energy, allowing gas to burn quickly and fully in the cylinder, increasing the engine's explosive power and thus enhancing power- Operation: Select a spark plug with a heat value that matches the vehicle engine and has high ignition energy. For example, iridium or platinum spark plugs have thinner electrodes, which can concentrate ignition energy and have better ignition performance than ordinary spark plugs. According to the requirements of the vehicle maintenance manual, replace the spark plug correctly, pay attention to the installation torque, and avoid being too tight or too loose, which will affect the ignition effect.

Optimize the intake system

1. Principle: Adequate and smooth air entering the cylinder can better mix and burn with gas, improve combustion efficiency, and enhance power. Optimizing the intake system can increase the intake volume and speed, providing more favorable conditions for combustion- Operation: One is to replace the high flow air filter, which is made of special materials and designed to filter air while allowing more air to pass through, increasing the intake volume.

2. The second is to install an intake resonator or intake boosting device (such as auxiliary modification of turbocharging), the former can adjust the intake frequency to make the intake smoother; The latter can forcibly increase the intake pressure, significantly increase the intake volume, and significantly enhance power, but the modification of the intake boosting device is more complex and requires professional skills and matching adjustments.

3. Adjust the engine ignition advance angle: - Principle: The combustion speed of natural gas is relatively slow compared to gasoline. Appropriately advancing the ignition advance angle can allow the gas to start burning earlier before the piston reaches the top dead center, making the combustion process closer to the ideal state. When the piston descends to do work, more energy is released, improving power- Operation: Use professional automotive diagnostic equipment to read the ignition advance angle data of the engine, and adjust it based on the combustion characteristics of natural gas and engine operating conditions. However, adjusting the ignition advance angle requires careful operation, as being too large or too small may lead to engine knock, decreased power, and other issues. It is necessary to gradually adjust and determine the optimal advance angle through actual road tests.

Other aspects

1. Keep the vehicle in good condition: - Principle: The overall mechanical condition of the vehicle has a significant impact on power output. For example, severely worn tires can increase rolling resistance and consume engine power; Abnormal operation of transmission system components such as clutches and gearboxes can lead to increased power transmission losses. Keeping the vehicle in good condition can reduce power loss and enable more effective transmission of engine output power to the wheels- Operation: Regularly inspect and replace worn tires to ensure normal tire pressure; Inspect and maintain the transmission system, such as checking the wear of clutch plates and replacing them in a timely manner; Regularly replace the transmission oil to ensure good lubrication and normal operation of the internal components of the transmission. In addition, it is important to pay attention to the overall maintenance of the engine, such as regular oil changes, cleaning of carbon deposits, etc., to maintain the efficient operation of the engine.

2. Reasonable driving: - Principle: Driving habits have a significant impact on vehicle power performance and energy consumption. A reasonable driving style can fully utilize the performance of the engine and gas system, reducing unnecessary power waste- Operation: Avoid sudden acceleration and braking, smoothly control the accelerator pedal to increase the engine speed smoothly, better match the gas supply with the engine demand, and improve combustion efficiency. Anticipate road conditions in advance, shift gears reasonably, and ensure that the engine runs in the economic speed range, which can save gas and ensure power output. For example, during the start-up and acceleration phases, slowly step on the accelerator to evenly increase the engine speed; During the driving process, shift gears in a timely manner according to the vehicle speed and road conditions to avoid the engine being in a high load and low efficiency working state for a long time.
