What I admire most about the BMW 320Li is its engine specifications. The 2.0-liter turbocharged four-cylinder engine delivers 184 horsepower and a maximum torque of 290 Nm. From a technical perspective, it features BMW's B48 series engine with a displacement of 1998cc, equipped with twin-scroll turbocharging technology to reduce lag. The compression ratio of 11:1 requires 95-octane or higher gasoline, ensuring efficient combustion. In terms of driving experience, the power response is quick in low-speed urban areas, making it easy to start from traffic lights, and highway overtaking is also effortless. Paired with an 8-speed automatic transmission, gear shifts are smooth. The official fuel economy data is 6.5L/100km, while my actual city driving consumption is around 8-9L, dropping to about 6L on highways. For routine maintenance, it is recommended to change the oil and filter every 10,000 km to prevent carbon buildup. Overall, the engine is highly reliable, with a compact design that reduces weight and enhances driving pleasure.

As a BMW 320Li owner for over a year, I find its 184 horsepower and 290 N·m torque perfectly practical for daily driving. In city traffic, it accelerates promptly with just a light throttle to keep up with traffic flow. During highway cruising, the engine remains quiet and smooth, with minimal noise unless you floor the accelerator. Fuel efficiency is pleasantly surprising – while the manual claims a combined 6.7L/100km, my real-world city driving averages just over 9L, dropping to around 6L on highways, saving significant monthly fuel costs. The B48 engine's automatic start-stop system cuts the engine when stationary to further reduce consumption. Compared to rivals, its specs aren't the most aggressive but offer reliable durability with straightforward maintenance – just a check-up every 10,000 km – making it ideal for comfort-focused, economical drivers like me.

Having worked on numerous BMW 320Li engines, the specifications are 2.0T turbocharged four-cylinder with 184 horsepower and 290Nm torque. The B48 engine is not difficult to maintain, with the key being oil changes every 10,000 kilometers and checking the turbo for oil leaks. Common issues include sensor problems, but overall it's durable with sufficient repair space. The 184PS horsepower is more than adequate for daily commuting, with peak torque starting at a low 1350 rpm, providing quick acceleration and ease of driving. Fuel economy averages around 8L per 100km, slightly higher in urban areas. It's recommended to use higher-grade gasoline to avoid carbon buildup. Regular maintenance, such as spark plug replacements, helps maintain optimal performance.

What Are the Maintenance Items for Automatic Transmission Vehicles?

Engine oil, transmission fluid, rear axle oil for rear-wheel drive vehicles, oil filter, air filter, fuel filter, and vehicle lighting system, etc. Below is relevant information about vehicle maintenance: 1. First Maintenance: Some manufacturers determine the first maintenance based on time or mileage. The exact timing for the first maintenance should be referred to the vehicle's user manual or warranty manual. The first maintenance is very important and is usually free, so it is crucial to remember to get it done to avoid missing it, which could affect the vehicle's third maintenance. 2. Maintenance Items: The main maintenance items for a vehicle include replacing engine oil, oil filter, transmission fluid, spark plugs, cabin air filter, engine air filter, brake fluid, etc. However, not all items need to be replaced during every maintenance session; this depends on their service life. In addition, maintenance also involves the inspection and upkeep of dozens of items across multiple systems such as the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.

How often should a five-seater sedan be inspected after six years?

A five-seater sedan should undergo inspection every two years after the initial six-year period. Below are the new regulations for vehicle inspections: 1. Expanded scope of exempted motor vehicle inspections: In addition to the existing exemption for non-operational small and micro passenger vehicles with six seats or fewer within six years, non-operational small and micro passenger vehicles with 7 to 9 seats (excluding minivans) within six years are now also included in the exemption. For non-operational small and micro passenger vehicles (excluding minivans) that are over six years but less than ten years old, the inspection frequency is adjusted from once a year to once every two years. 2. Optimized application conditions for medium and large passenger and truck driving licenses: The minimum age requirement for applying for a large passenger vehicle or tractor driving license is lowered from 26 and 24 years old to 22 years old, respectively. The maximum age limit for applying for medium and large passenger and truck driving licenses is raised from 50 years old to 60 years old.

Should the Mondeo use 92 or 95 octane gasoline?

The Mondeo should use 95 octane gasoline. This gasoline grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, the fuel filler cap will also indicate the recommended grade. Usually, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. If the compression ratio is higher, 98 octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade, as high compression ratio engines can also be tuned to use lower octane gasoline. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Mondeo occasionally uses the wrong gasoline grade, simply switch back to the correct grade after the current tank is used up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, with the actual feedback being poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Due to the significantly lower octane number, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. If the knocking is mild, it only increases noise without significant engine damage. However, severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What Gear Should an Automatic Car Use When Crossing Water?

After an automatic car enters water, using D gear is sufficient for shallow water, while L gear is needed for deeper water. Below are relevant introductions about vehicle wading: 1. Introduction to Vehicle Wading: Vehicle wading, as the name suggests, refers to driving a vehicle on low-lying, waterlogged roads, passing through water. This usually occurs during rainy weather in low-lying areas where inadequate drainage leads to water accumulation on the road. 2. Precautions for Vehicle Wading: Before wading, observe the road conditions carefully; maintain steady power while in the water; after wading, check the electrical system. If a car stalls in water, the main reason is water entering the exhaust pipe, and in some cases, there may also be electrical damage. Once a car stalls in water, do not attempt to restart it, as this may cause water to enter the intake manifold and damage the valves, potentially leading to severe engine damage in serious cases. Instead, the car should be towed to a 4S shop immediately for professional handling.

What does O/D mean in an automatic transmission?

The O/D switch (overdrive) on the gearshift refers to overdrive transmission, which is commonly found in non-manual-automatic transmissions. Here is an introduction to the O/D button: 1. Automatic transmission O/D: O/D is the abbreviation for OVERDRIVE, meaning overdrive transmission, typically used in non-manual-automatic transmission models, especially common in Japanese cars. This button is generally not used in daily driving. Taking a 4-speed automatic transmission as an example, when the transmission gear ratio is less than 1 during operation, this gear is called OVERDRIVE. For instance, when the 4th gear ratio is 0.697, it means the engine turns one revolution while the transmission turns only 0.697 revolutions. This allows the engine to increase the car's speed without requiring high RPMs, thereby improving fuel economy and reducing wear on internal engine components, extending the engine's lifespan. 2. Location and function: Typically, this button is designed on the side of the gearshift lever, while some models place it on the center console. When driving at high speeds or needing to overtake, activating the O/D gear can reduce engine load, eliminating the need for high RPM operation and lowering fuel consumption. In congested traffic, pressing the O/D button prevents the transmission from shifting to the 4th gear and reduces unnecessary switching of the shift solenoid valve.

How Long After Turning Off the Engine Can You Open the Coolant Cap?

After turning off the engine, wait for about 20 minutes, then touch the radiator hose. If it doesn't feel hot, you can safely open the coolant cap. Coolant Replacement Cycle: For vehicles that run for extended periods, such as taxis, high-quality coolant should generally be replaced once a year. For vehicles with shorter running times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foaming, which reduces the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolants can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the coolant, replace it promptly and clean the system. Coolant Composition: The main components of coolant are: 50% purified water, 40% methanol, and 10% other substances. Choosing Coolant: The basic indicators for coolant are its freezing and boiling points. Available in the market are coolants with freezing points of -15°C, -25°C, -30°C, -40°C, etc. It's advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region.
