The reasons for a strong smell of gasoline in the car are: fuel system leakage, aging of the fuel system, or overfilling of gasoline. Gasoline is a volatile, flammable liquid hydrocarbon mixture derived from petroleum through distillation or cracking processes, primarily used as fuel for spark-ignited internal combustion engines. It mainly consists of organic compounds obtained from crude oil distillation and various additives. The octane rating of gasoline measures its anti-knock properties (which can cause knocking and reduce the efficiency of reciprocating engines). Based on different octane ratings, gasoline is produced in several grades.

What are the differences between the e200 and e260?

The main differences between the e200 and e260 are as follows: 1. Power. In terms of power and displacement, both the Mercedes-Benz E200 and E260 use a 2.0-liter inline 4-cylinder turbocharged engine. The data shows that the two engines are completely identical. The 0-100 km/h acceleration time of the two models differs by only 0.1 second, and both can reach a top speed of over 240 km/h. 2. Exterior. First, the rear badges are the most obvious difference, with one being E200 and the other E260. Secondly, the wheel rims are also different, and the tires are 245/40R19 for one and 245/45R18 for the other.

Where is the Crankshaft Position Sensor Located on a Toyota Crown?

Toyota Crown's crankshaft position sensor is located inside the air conditioning compressor, and it can be seen by removing the lower guard plate. The working principle of the crankshaft position sensor is to provide the ignition timing (ignition advance angle) and confirm the crankshaft position signal, which is used to detect the piston top dead center, crankshaft angle, and engine speed. The function of the crankshaft position sensor is to determine the position of the crankshaft, that is, the angle of the crankshaft and the engine speed. The measurement method of the crankshaft position sensor is as follows: 1. Check that the normal gap between the crankshaft position sensor and the pulse wheel (target wheel) should be greater than 0.5mm and less than 1.2mm. If the pulse wheel is installed incorrectly, too large or too small, it may cause signal deviation. 2. Turn off the ignition switch, disconnect the crankshaft position sensor connector, and measure that there should be 400~600Ω between terminal 1 and terminal 2 of the sensor. If it is not within this range, it can be determined that the crankshaft position sensor itself is faulty and should be replaced. The two signal lines and the shielding wire of the crankshaft position sensor are insulated. 3. Turn on the ignition switch, and measure that the voltage of the two signal lines to ground should be 1.4V, which is the preset voltage of the engine control unit on the signal lines. When starting the starter, measure the signal voltage of the crankshaft position sensor should be close to 1.6V. If the sensor is internally open or short-circuited, the signal lines, or the engine control unit are internally open or short-circuited, the computer will not be able to receive the crankshaft position signal, thus causing the engine to fail to start.

Where is the trunk switch on the old Jetta?

The trunk switch on the old Jetta model is simply a contact point. There is a pressable spot on the left side of the door lock position where the lid lifts up, which serves as the trunk switch. For the new Jetta models, the trunk is usually opened with the key, and some have a trunk opening switch on the center console. Additional information: 1. Structure-wise. The Jetta, along with the later Vento and Bora models, are essentially Golfs with an added rear trunk. The Jetta can be considered a derivative of the Golf. 2. Engine-wise. In China, the Jetta was the first to adopt the world's advanced 5-valve multi-point electronic fuel injection engine. With its unique product design performance and comprehensive safety technology features, it established a distinct product personality for the Jetta series of sedans.

How much engine oil should be added to a BMW 5 Series 2.0t?

The 2.0t engine of the BMW 5 Series requires 5 liters of engine oil. Here is some introduction about car engine oil: 1. The function of BMW 5 Series engine oil is to lubricate and clean the engine. 2. It can be divided into three types: mineral oil, synthetic oil, and semi-synthetic oil. All engine oils are composed of base oil and additives. 3. Overall, full synthetic oil contains 100% non-conventional, high-performance fluids. Semi-synthetic oil contains a smaller percentage of such high-performance fluids and includes conventional mineral oil. Additional information: If too much engine oil is added to the BMW 5 Series, the amount of oil splashed into the cylinder wall when the crankshaft and connecting rod rotate increases, which means the amount of oil entering the combustion chamber greatly increases. This leads to more carbon deposits in the combustion chamber, increases the resistance of piston movement, and reduces engine power. As the amount of oil entering the combustion chamber increases, exhaust emissions deteriorate, affecting the lifespan of the three-way catalytic converter. In severe cases, it may even damage the three-way catalytic converter.

Where is the Lavida's air filter located?

Volkswagen Lavida's air filter element is located on the upper left side of the engine compartment cover. Steps to replace the Volkswagen Lavida air filter element: 1. Open the Lavida's engine compartment cover, secure the support rod, and locate the air filter position; 2. Use a screwdriver to loosen the screws around the filter cover (some filter covers are secured with clips, then release the clips), being careful not to let the screws or clips fall into the engine compartment; 3. After opening the cover, remove the air filter element, paying attention to the direction of the filter element when taking it out; 4. Inspect the filter element and clean it. If the filter surface is damaged or excessively dirty, it is recommended to replace it; 5. Place the new filter element back into the filter housing, ensuring correct orientation, then reattach the cover, secure the clips, and tighten the screws.

What kind of transmission does the Toyota RAV4 use?

Toyota RAV4 refers to the RAV4 Rongfang. There are many models of the RAV4 Rongfang, and different models use different transmissions. Taking the 2020 RAV4 Rongfang as an example, there are two types of transmissions used: 1. CVT (Continuously Variable Transmission). 2. E-CVT (Electronic Continuously Variable Transmission). Extended content: 1. Among them, traditional gasoline vehicles use a CVT (Continuously Variable Transmission), while hybrid models use an E-CVT (Electronic Continuously Variable Transmission). 2. The principle of E-CVT: It uses a set of planetary gears to achieve the 'fusion' of engine power and electric motor power. 3. CVT (Continuously Variable Transmission) is a type of automatic transmission. The CVT transmission does not have real gears, so there is no sense of jerkiness or impact when shifting, and the entire shifting process is very linear.
