What engine is used in the BMW 1 Series?

The 1.5T engine model of the BMW 1 Series is B38A15C, with a maximum power of 103kW and a maximum torque of 220Nm. The 2.0T engine model is B48A20C, with a maximum power of 141kW and a maximum torque of 280Nm. The engine of the BMW 1 Series is produced by the Liaoning Tiesi Engine Factory and is a domestically manufactured engine. For the daily maintenance of the BMW 1 Series engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, causing various problems for the engine. To avoid faults, change the oil regularly according to usage conditions and keep the oil level moderate. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and bring contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine works properly but also extends the overall lifespan of the radiator and engine.

What does an exclamation mark in a circle mean?

Red exclamation mark (specifically in the form of an exclamation mark inside a circle), this represents a warning for the braking system, mainly indicating a malfunction in the braking system or low brake fluid level. Solution: Immediate inspection and repair of the braking system are required to avoid accidents. Apart from the red exclamation mark indicating braking system issues, all other exclamation marks on a car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four scenarios: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. This mainly includes parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. Transmission oil should be replaced promptly. Abnormal Tire Pressure: An exclamation mark with a horizontal line below a bracket. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in the car's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

What items are needed for a car's first maintenance?

The items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's registration certificate; vehicle's purchase invoice, to be taken to the designated first maintenance facility for the vehicle's first service. Important notes: Make an appointment with the 4S store in advance. The first maintenance refers to the initial service after a new car has been driven, with the specific time varying by vehicle, usually after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance promptly, neither in advance nor delayed. The completion of the first maintenance signifies the end of the car's break-in period, allowing the vehicle to be driven under standard loads and normal speeds as required. The timing for the first insurance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first will be the standard. First maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and examining tires for damage or bulges. Required time: Approximately 2 hours to complete all tasks. The most crucial aspect of a new car's first maintenance is changing the engine oil and oil filter. When changing the oil, the oil filter must also be replaced. The selection of engine oil must refer to the "Vehicle Use and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It is important to note that the car's interior should not be directly washed with water. If the floor mats are dirty, use a vacuum cleaner or remove them to brush and clean with detergent, dry them, and then put them back. There are many drainage holes under the rubber mats on the floor of the driver's compartment. If water enters, it will not dry but flow through these holes to areas like the transmission, causing corrosion. The best practice is to use a vacuum cleaner for cleaning, followed by wiping with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the car's antifreeze is low, it is recommended to drain the existing antifreeze and add the same brand from the start. Different brands of antifreeze have varying chemical properties, and their corrosion inhibitors may react negatively with each other. Mixing different brands can lead to unnecessary problems. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. Some people apply lubricant to the bolts and nuts to prevent rust, but this can pose safety risks. At high speeds, the bolts and nuts may loosen or even fall off, leading to driving hazards. Do not press the accelerator when starting an EFI car: The starter of an EFI (Electronic Fuel Injection) car differs from that of a conventional car. Its fuel injection control system can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.

Is 95 Octane Gasoline Mandatory for the Lavida 1.4T?

According to the official vehicle manual recommendation, the Lavida 1.4T should use 95 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, the Lavida 1.4T's fuel cap also indicates the recommended octane rating. Generally, 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 opt for 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot solely determine the gasoline grade. High compression ratio engines can be tuned to use lower octane gasoline because factors beyond compression ratio, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, higher octane gasoline has a higher octane number and better anti-knock properties. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. If the Lavida 1.4T occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, prolonged use of the wrong gasoline grade can have the following effects: For vehicles recommended for lower octane gasoline, using higher octane gasoline will not cause damage, but the increased octane number alters the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, manifesting as poorer performance. For vehicles recommended for higher octane gasoline, using lower octane gasoline can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is generated during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but noticeable knocking indicates severe engine conditions. The vibrations not only affect driving stability but also cause abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in severe cases.
