Engine oil filler port is generally located on the left side of the engine. Under the yellow circular cap on the engine cylinder head is the oil filler port. Engine oil, also known as engine lubricant, serves multiple functions including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Below is a detailed introduction to automotive engine oil: 1. Engine oil consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of base oil performance, endowing it with certain new characteristics, making them an essential part of lubricating oil. 2. The engine is the heart of a car, containing many metal surfaces that move against each other. These components operate at high speeds, in harsh environments, with working temperatures reaching 400°C to 600°C. Under such severe operating conditions, only qualified lubricating oil can reduce engine component wear and extend service life.

What's the reason for the car not starting after refueling?

If the car fails to start after refueling and it's confirmed that there are no issues with the car itself, it is generally due to the following possibilities: 1. The fuel pump pressure is reduced, leading to insufficient fuel pressure. 2. Poor-quality gasoline was added, resulting in inferior fuel quality (containing excessive impurities or water). 3. The weather is too hot, and the tank was overfilled, causing thermal expansion and contraction, which creates vapor lock in the fuel line. 1. Choose reputable gas stations: The quality of the fuel affects the amount of carbon deposits on the fuel injectors, and clogging caused by substandard fuel is common. Always refuel at established gas stations, preferably those rated by Sinopec or PetroChina, to ensure fuel quality. Remember to get a receipt after refueling as proof. 2. Avoid refueling during thunderstorms: This is also a safety precaution to prevent lightning strikes and avoid fires. Since gasoline is highly flammable, during refueling, flammable fuel vapors can disperse into the surrounding air. If struck by lightning, the consequences could be catastrophic.

What is the brand of business vehicles starting with 'm'?

Brands of vehicles starting with 'm' include: Maserati, Maybach, Mazda, Mercedes-Benz, BMW Mini, etc. Below is relevant information about business vehicles: 1. Introduction to business vehicles: Business vehicles - MPV: The full name of MPV is Multi-Purpose-Vehicle, which means multi-purpose vehicle. Business vehicles combine the functions of sedans, station wagons, and vans. Every seat in the vehicle can be adjusted and has multiple combination methods, such as flipping down the back of the middle row seats to turn them into a table, and the front seats can rotate 180 degrees. 2. Design: MPV is the abbreviation of Mini-Passenger-Van, originally meaning small passenger vans. Later, the French company Renault improved this model by introducing the concept of folding to the second and third row seats, so since then, MPV has a new meaning Multi-Purpose-Vehicle, emphasizing versatility, combining sedans, station wagons, and business vehicles into one model. The standard bullet-shaped body, the retro-style column shift design... Since the first Multi-Purpose-Vehicle (MPV) was introduced in 1983, MPV has conquered countless users with its practical personality. Unfortunately, in people's eyes, this practical feature seems to be everything about MPV.

Why Can't the Car Start?

The reasons why a car cannot start include: starter motor failure; insufficient battery voltage; fuel pump damage; car gear stuck in D position; engine speed sensor (crankshaft position sensor) failure; excessive carbon buildup in the vehicle; or lack of antifreeze. Specific reasons are as follows: 1. Starter motor failure: The typical lifespan of a starter motor is around 100,000 kilometers. Prolonged use can lead to carbon brush wear, causing the starter motor to fail. Timely replacement of the starter motor is necessary. 2. Insufficient battery voltage: This prevents the starter from engaging the engine. The battery needs to be recharged promptly. 3. Fuel pump damage: This results in no fuel supply. The fuel pump must be replaced. 4. Car gear stuck in D position: This is a self-protection mechanism of the car to prevent it from lurching forward after ignition. Simply shift back to the normal gear position. 5. Engine speed sensor (crankshaft position sensor) failure: This causes the vehicle to lack high-voltage spark, preventing normal startup. Replacement is required. 6. Excessive carbon buildup in the vehicle: Regular highway driving can help reduce carbon buildup. 7. Lack of antifreeze: Adding water or low-quality antifreeze to the car can cause the entire cooling system to freeze in extremely cold winter conditions, leading to engine block cracking, water pump failure, inability to start, and damage to other engine components.

How Many Kilometers Should a Car Typically Be Driven Before Replacement?

Household sedans are essentially the same models as taxis. Taxis are generally scrapped after running about 1 million kilometers. For household cars, assuming an annual mileage of 20,000 kilometers (an average of 55 kilometers per day, which is a figure many people cannot reach), it would take 30 years to reach 600,000 kilometers if the car is well maintained. If the annual mileage is 50,000 kilometers (136 kilometers per day), it would take 12 years to reach 600,000 kilometers. Therefore, most household cars are scrapped due to aging rather than excessive mileage. The compensation standards for cars being scrapped in accidents are as follows: 1. First category: When the repair cost exceeds 80% or more of the vehicle's value, the insurance company will settle the claim as a total loss. 2. Second category: The vehicle meets the mandatory scrapping standards. According to Article 4 of the 'Mandatory Scrapping Standards for Motor Vehicles,' registered motor vehicles shall be mandatorily scrapped under the following circumstances: First clause: After repair and adjustment, the vehicle still fails to meet the national safety technical standards for in-use vehicles; Second clause: After repair and adjustment or the adoption of control technologies, the vehicle's emissions or noise still fail to meet the national standards for in-use vehicles.

What engine is used in the Zhonghua H530?

Zhonghua H530 is equipped with a 4A92S engine from Aerospace Mitsubishi, with a displacement of 1.6L, maximum power of 87kW/5600-6000rpm, and maximum torque of 151Nm/4000rpm. The 4A92S engine is Mitsubishi's new-generation small-displacement engine that replaces the 4G series. In China, it is mainly produced by Aerospace Mitsubishi and has been installed in many domestic brand models, with the most common being the 1.5L 4A91 (the one used in the Southeast Lingyue). Several previous models from Brilliance (such as the Junjie) used Mitsubishi's 4G series engines, so it's not surprising that the H530 now uses Mitsubishi's 4A9 series engine. The standard configuration of the 2017 Zhonghua H530 is as follows: 1. Safety features: driver/passenger airbags, seatbelt reminder, rear child seat interface, tire pressure monitoring, ABS anti-lock braking, brake force distribution, and brake assist. 2. Braking and suspension: The front and rear brakes of the 2017 Zhonghua H530 are ventilated disc and disc types, respectively, with a handbrake for parking. The front and rear suspensions of the 2017 Zhonghua H530 are MacPherson independent suspension and torsion beam non-independent suspension, with electric power steering.
