Is an engine idle speed of 700 to 800 RPM appropriate?

An engine idle speed of 700 to 800 RPM is appropriate, as the normal range is 700-800 RPM. If the speed is too low, the engine may vibrate excessively, while a higher speed increases fuel consumption. As long as there is no vibration, design engineers generally aim for the lowest possible idle speed to save fuel. The idle speed may automatically increase by 50-150 RPM under the following conditions: Cold start when the engine coolant temperature is low; battery is low on charge; air conditioning is turned on for cooling. Hazards of unstable idle speed: If the idle speed is too high, check for loose or leaking intake manifold, as it will significantly increase fuel costs and accelerate carbon buildup in the engine. If the idle speed is too low, there is a risk of stalling while driving. If the idle speed fluctuates, it may indicate issues with spark plugs or ignition coils, causing the engine pistons to malfunction and leading to severe vibrations.

Do I Need to Go to the Car Dealership Where I Bought the Car for Maintenance?

Maintenance does not necessarily have to be done at the dealership where you bought the car. Any authorized dealership nationwide that matches your car's brand and model will suffice. Whether you should go to a dealership for car maintenance depends entirely on your personal circumstances, including your income and the condition of your vehicle. Additional Information: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as vehicle upkeep. 2. Modern car maintenance primarily includes servicing the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and more. 3. The purpose of car maintenance is to keep the vehicle clean and in good technical condition, eliminate potential hazards, prevent malfunctions, slow down deterioration, and extend the vehicle's lifespan.

What is the normal pressure of a car air conditioner?

Car air conditioner normal pressure is: 1. Low pressure between 1.0 to 2.5 bar; 2. High pressure between 15 to 18 bar. More related information: The car air conditioning device, referred to as car AC, consists of a refrigeration system, heating system, air purification device, and control system. It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to an optimal state. The functions of car air conditioning are: 1. To adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to an optimal state; 2. To provide passengers with a comfortable riding environment and reduce travel fatigue; 3. To create good working conditions for the driver and ensure driving safety.

Does the car need to warm up when starting?

Car starting requires warming up because the engine temperature is low when just started, and the lubricating oil in various parts has not yet reached its position. Driving immediately will cause dry friction of mechanical parts and wear out components. More relevant information is as follows: 1. The warm-up time does not need to be too long. The criterion is that when the water temperature gauge pointer just starts to move, or the engine tachometer drops back to idle speed after starting, you can drive. It takes about one minute. 2. The engine needs lubrication to work. After being stationary for a long time, the lubricating oil will flow back into the oil pan. Therefore, it is necessary to idle first to allow the lubricating oil to fully lubricate all parts that need lubrication before adding load work, which is beneficial to prolonging the engine's life.

China National I Emission Standard?

China National I standard vehicles refer to motor vehicles produced under the first phase of the national emission standards implemented, abbreviated as National I standard vehicles. In other words, most motor vehicles purchased between January 1, 1999, and December 31, 2003, fall within the scope of National I vehicles. From January 1, 1999, to December 31, 2003, China referenced the European Emission Standard I, taking passenger cars with a designed seating capacity of no more than 6 people (including the driver) and a maximum total mass not exceeding 2.5 tons as an example. During this period, the emission standard limits that had to be met were: carbon monoxide must not exceed 3.16g/km; hydrocarbons must not exceed 1.13g/km; for diesel vehicles, particulate matter standards must not exceed 0.18g/km; and the durability requirement was 50,000 km. Additional information is as follows: Other phases of automobile emission standards: 1. Phase II: Between 1989 and 1993, China successively issued two limit standards and two test method standards based on driving cycles. By then, China had established a relatively complete system of automobile exhaust emission standards. 2. Phase III: Starting in 1999, Beijing implemented the local regulation DB11/105－1998, and from 2000, the national standard GB14961－1999 "Limits and Measurement Methods for Emissions from Vehicles" was implemented nationwide, bringing China's automobile exhaust emission standards up to the level of the early 1990s in foreign countries. 3. Phase IV: In 2008, Beijing implemented the "China National IV Emission Standard for Motor Vehicles" (referred to as "National IV") for all newly added motor vehicles in the city. The supply of National IV standard automotive fuel began citywide on January 1, 2008.

Is It Necessary to Clean the Car Air Conditioning?

Cleaning the car air conditioning is highly necessary. Here are the manual cleaning methods for the air conditioning: 1. Clean the air conditioning filter. The normal lifespan of the original car air conditioning filter is one year. Regularly cleaning the air conditioning filter will maintain fresh air inside the car. 2. Clean the air conditioning ducts. Ordinary air conditioning cleaners and disinfectants can be used to clean the air conditioning. Before cleaning, shake the air conditioning cleaner well, then spray it directly onto the filter. The built-in suction of the air conditioning will draw in the cleaner, thereby cleaning the ducts. 3. Clean the evaporator. When cleaning the evaporator, it is necessary to first remove the air conditioning pipes and the evaporator. This can be done at a car maintenance or repair shop. 4. Clean the air conditioning condenser. Open the front bumper of the car to expose the condenser, then use a water gun to clean the dirt on the condenser.
