What does idle operation mean?

Idle speed refers to the operation of the engine under no-load conditions, where it only needs to overcome the frictional resistance of its internal components without delivering power externally. The minimum rotational speed required to maintain stable engine operation is referred to as idle speed. Below is an introduction related to engine idle operation: 1. Explanation: When the engine is idling, the reading on the oil pressure gauge indicates the idle working pressure of the fuel supply system, which is generally 0.25MPa or complies with the technical specifications of the vehicle model. When checking the idle working pressure, the oil pressure should rise to 0.3MPa after removing the vacuum tube from the fuel pressure regulator; otherwise, the oil pressure regulator should be replaced. 2. Precautions: During engine operation, it is essential to frequently monitor the readings of the oil pressure gauge and coolant temperature gauge. If the oil pressure and coolant temperature values significantly deviate from the norm, the engine should be shut down immediately for inspection, or a car service station should be contacted.

What is the reason why a dual-fuel vehicle suddenly cannot switch to gas?

Conversion switch or the circuit controlling the conversion switch may have problems, and it needs to be repaired at a 4S shop. The following is a detailed introduction about dual-fuel vehicles: 1. Overview: A dual-fuel vehicle refers to a vehicle that uses both fuel and liquefied petroleum gas (LPG) as fuel, mainly existing in the taxi market. 2. Advantages: Stable combustion, no knocking, and convenient cold and hot starts. The storage, transportation, decompression, and combustion of compressed natural gas are carried out under strict sealing conditions, making leakage unlikely. In addition, the gas cylinders have undergone various special destructive tests, ensuring safety and reliability. Compressed natural gas burns safely, produces less carbon deposits, reduces vapor lock and knocking, which helps extend the service life of various engine components, reduces the number of maintenance and repairs, and significantly lowers maintenance costs. 3. Disadvantages: Due to the low energy density of gaseous fuels, natural gas vehicles carry less fuel and generally have a shorter driving range than gasoline vehicles. Since gaseous fuels occupy a certain volume in the combustible mixture in the cylinder (the volume occupied by liquid fuel in gasoline engine cylinders is negligible), the work done when using natural gas as fuel is less under the same cylinder working volume.

Does V Represent Five or Four?

V represents five. Below are the specific details of automotive emission standards: 1. China III Emission Standard: Implementation times were July 1, 2009, for light-duty diesel vehicles; July 1, 2010, for heavy-duty gasoline vehicles; and July 1, 2008, for heavy-duty gas vehicles and heavy-duty diesel vehicles. 2. China IV Emission Standard: Nationwide implementation times were July 1, 2013, for light-duty diesel vehicles and heavy-duty gasoline vehicles; January 1, 2011, for heavy-duty gas vehicles; and July 1, 2013, for heavy-duty diesel vehicles. 3. China V Emission Standard: The nationwide implementation of the China V emission standard began on July 1, 2017, which reduces nitrogen oxide emissions by 25% compared to the China IV standard and introduces stricter PM emission limits. 4. China VI Emission Standard: The China VI standard will be divided into two phases, 6A and 6B. The first phase, starting from July 1, 2020, prohibits the sale, registration, and licensing of vehicles below the 6A emission standard. The second phase, starting from July 1, 2023, prohibits the sale, registration, and licensing of vehicles below the 6B emission standard.
