What is the fuel tank capacity of the 2020 Mercedes-Benz E300L?

2020 Mercedes-Benz E300L has a fuel tank capacity of 80 liters, and the recommended gasoline specification is No. 95 or higher unleaded gasoline. The 2020 Mercedes-Benz E300L is equipped with multi-link independent suspension both in the front and rear. It is powered by a 1.5T turbocharged engine, delivering a maximum horsepower of 184 PS, a maximum power of 135 kW, and a maximum torque of 280 Nm. The engine is paired with a 9-speed automatic transmission. To check the remaining fuel level, the driver can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the needle is close to E, it indicates low fuel, while proximity to F means sufficient fuel. Fuel tank maintenance includes the following steps: Drain accumulated water and sediment from the fuel tank, and check for any oil leaks at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and vapor valves, ensure that the ventilation holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank and clogging the fuel lines during refueling. The sealing gasket on the fuel filler cap should also be in good condition to prevent fuel spillage while driving.

What Causes the Abnormal Noise When Deeply Pressing the Accelerator in a Roewe 350?

Abnormal noise when deeply pressing the accelerator in a Roewe 350 is related to the engine speed. Most common abnormal noises in the engine depend on the engine's speed state. The specific causes of abnormal noises under the following three conditions—idling or low-speed operation, normal speed, and sudden engine acceleration—are as follows: When idling or operating at low speed: The cause of the noise may be excessive clearance between the piston and cylinder wall; the piston pin being too tightly assembled or the connecting rod bearing being too tightly assembled; excessive clearance between the tappet and its guide hole; wear on the camshaft profile; sometimes, the starter clutch loosens, causing the pulley to make noise (especially noticeable when the speed changes). When the noise becomes chaotic at a certain speed: Short noises are emitted successively during sudden deceleration of the car. The cause of the noise may be a cracked camshaft timing gear or its fixing nut being loose; a broken crankshaft; a loose piston pin bushing; excessive axial clearance of the camshaft or its bushing being loose. When the abnormal noise occurs during sudden engine acceleration: The abnormal noise persists when the car maintains high-speed operation. The cause of the noise may be a loose connecting rod bearing, melted or mismatched bearing shells causing rotation; loose crankshaft bearings or melted bearing shells; a broken piston pin; a broken crankshaft.

Can the Third Subject Guarantee a 100% Pass Rate?

There is no 100% pass guarantee for the third subject. Below is expanded information about Subject Two: 1. Subject Two Content: Subject Two, also known as the minor road test, is part of the motor vehicle driver's license assessment. It refers to the field driving skill test. The test items for small vehicles C1 and C2 include five mandatory tests: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-curves). Some regions also include a sixth item: high-speed toll card collection. 2. Teaching Objectives: Master the basic essentials of driving operations and possess the fundamental ability to control the vehicle; proficiently master the basic methods of field and road driving within the test area, and have the ability to reasonably use vehicle control components and correctly control the spatial position of the vehicle movement, accurately controlling the vehicle's driving position, speed, and route.

Is there no limit to the number of attempts for Subject 4?

There is no limit to the number of attempts for Subject 4. The following are the regulations from "100 Questions on Orders No. 123 and 124 of the Ministry of Public Security": 1. Exam scheduling: The four subjects are scheduled for exams in sequence, and each subject can be taken once with one retake after scheduling. If the retake is not attended or still fails, the exam must be rescheduled. 2. Number of scheduling attempts: Within the validity period of the driving skills test permit, the number of scheduling attempts for Subject 2 and Subject 3 must not exceed five times each (i.e., ten exam opportunities each). If the fifth scheduled exam still fails, the results of other subjects that have been passed will be invalidated, and the student must start over from Subject 1. 3. Subject 1 and Subject 4: There is no limit to the number of scheduling attempts for Subject 1 and Subject 4. Subject 4 can only be taken after passing the road driving skills test of Subject 3. If the exam is failed, a retake can be directly applied for, and the previously passed road driving skills test results remain valid.

Does a car refrigerator have a significant impact on the car battery?

Car refrigerators do not affect the car battery. Here are the relevant details: 1. Principle: The car refrigerator is connected to the car's cigarette lighter socket via a power cord. When the car is running, it is powered by the excess electricity generated by the car engine. When the car is turned off, the refrigerator is powered by the battery (the cigarette lighter socket remains powered). 2. Engine: The electricity generated by the engine is more than sufficient to power the car refrigerator (with a power consumption of 35W, equivalent to a car navigation system), so there is no impact. 3. Consumption: When powered by the battery, the built-in battery protection module in the car refrigerator automatically recognizes the voltage and adjusts the frequency accordingly, ensuring no damage to the battery.

What happens if the engine stalls after the air filter gets wet?

If the engine stalls after the air filter gets wet, it may cause the engine to fail to start. Attempting to start the engine under such conditions can result in poor acceleration, a feeling of suffocation, and insufficient fuel supply. Below is some relevant information about the air filter: 1. Function: A high-quality air filter can absorb fine particles, reduce respiratory discomfort, minimize irritation for allergy sufferers, enhance driving comfort, and protect the air conditioning cooling system. 2. Usage precautions: The air filter is prone to accumulating a lot of dust. Use compressed air or similar methods to blow away the dust. Never wash it with water, as this can easily render it useless.
