What brand is the GW4B15A engine?

The GW4B15A engine is an engine produced by the Great Wall Group. The engine model used in the GW4B15A is the GW4C20B, with a maximum horsepower of 190 HP, a maximum power output of 140 KW, a maximum power speed range of 4000-5500 rpm, and a peak torque of 360 N·m. For daily maintenance of the GW4B15A engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to the mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will degrade during use. After a certain mileage, its performance will deteriorate, leading to various engine issues. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. 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 particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

What Causes Transmission Abnormalities While Still Being Able to Drive?

Transmission abnormalities while still being able to drive are caused by faults in the power electronic control system, indicating a malfunction in a certain sensor or wiring. Relevant information about transmissions is as follows: 1. Working Principle: Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations; whereas automatic transmissions (AT) are composed of hydraulic torque converters, planetary gears, and hydraulic control systems, achieving speed and torque variation through hydraulic transmission and gear combinations. 2. Inspection: During long-term use, due to frequent gear shifting, components in the transmission inevitably experience wear and deformation, leading to issues such as difficulty in shifting gears, automatic gear disengagement, and noise during operation, which affect performance. Therefore, in daily use, it is essential to regularly conduct full-load operational checks on the transmission, observing whether the transmission operates smoothly, if there are any abnormal gaps or noises, and promptly identifying the cause for adjustment or repair.

What Type of Vehicle is Suitable for Moving a Refrigerator?

For moving a refrigerator, it is best to use a box truck for transportation. If traffic regulations permit, a small pickup truck with a cargo bed can also be used. Vehicles are generally categorized into six types based on their usage: 1. Sedan: Also known as a passenger car, typically seating no more than nine people (including the driver). 2. Bus: Seating for more than nine people (including the driver), including city buses, long-distance coaches, and tourist buses. 3. Truck: Commonly referred to as a lorry, primarily used for transporting goods. 4. Tractor: Specifically designed for towing trailers or semi-trailers. 5. Specialized Transport Vehicle: Designed for specific cargo transportation needs, featuring specialized compartments and corresponding equipment, such as dump trucks, tanker trucks, refrigerated trucks, bulk cement trucks, and container trucks. 6. Special Purpose Vehicle: Mainly used for other tasks, such as ambulances, fire trucks, garbage trucks, sprinkler trucks, and various engineering vehicles.

Is 14 liters per 100 kilometers high?

14 liters means a fuel consumption of 14L per 100 kilometers. Whether this is high is relative. For example, it is considered high for small sedans with an engine displacement of around 1.6-2.0L, but it is normal for large-displacement vehicles, such as large SUVs. Ways to reduce fuel consumption: 1. Correctly adjust tire inflation pressure: Proper tire pressure can reduce rolling resistance and lower fuel consumption. Additionally, slightly higher tire pressure (about +0.2bar above the recommended value) can also save fuel. 2. Use in-car auxiliary electrical equipment moderately: Some electrical devices significantly increase fuel consumption, such as the air conditioning system's cooling function. If the heating purpose has been achieved, the seat heater should be turned off promptly. The rear window heater should also be turned off when there is no fog or ice. 3. Use gears correctly: Match the gear to the speed; avoid high speed with low gear or low speed with high gear. Shift gears in advance, ensuring the gear matches the appropriate speed, and avoid driving at high speeds with low gears or low speeds with high gears.

What do S and H represent in shock absorbers?

Shock absorbers generally have two adjustment directions: hard and soft. H stands for hard, and S stands for soft. Below is relevant information about shock absorbers: 1. Function: Shock absorbers (Absorber) are mainly used to suppress the oscillation of the spring after absorbing shocks and the impact from the road surface. When driving on uneven roads, although the shock-absorbing spring can filter out road vibrations, the spring itself still has reciprocating motion, and the shock absorber is used to suppress this spring bounce. If the shock absorber is too soft, the car body will bounce up and down. If the shock absorber is too hard, it will create excessive resistance, hindering the normal operation of the spring. 2. Matching: In the process of modifying the suspension system, hard shock absorbers should be paired with hard springs, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers. The device connected to the vibration-damping crankshaft is used to counteract the torsional vibration of the crankshaft (i.e., the phenomenon where the crankshaft twists under the impact force of cylinder ignition).

How many points are deducted for making a U-turn and driving in the wrong direction on the road?

Making a U-turn and driving in the wrong direction on the road will result in a deduction of 3 points. Driving in the wrong direction refers to motor vehicles or non-motor vehicles driving on the left side, which is considered as driving in the wrong direction. Circumstances where U-turns are prohibited are as follows: U-turns are prohibited where there are "No U-turn" signs or "No Left Turn" signs: If there is a sign prohibiting U-turns, then U-turns are not allowed at that intersection. The action of making a U-turn is an extension of a left turn, so if there is a sign prohibiting left turns at an intersection, U-turns are also prohibited there. U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If at an intersection where U-turns are permitted, you must cross the crosswalk before making a U-turn and must not make a U-turn on the crosswalk. U-turns are prohibited when there is no left-turn lane: Even if you are in the leftmost lane, if there is no sign allowing left turns, U-turns are not permitted. U-turns are prohibited within the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any directional signs, vehicles can only make U-turns from the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line to make a U-turn. U-turns are prohibited on highways: Crossing the central divider to make a U-turn on a highway is illegal and will result in a fine and a deduction of 12 points. If you miss an exit on the highway, continue driving to the next exit and leave the highway. Do not attempt an illegal U-turn. Precautions for making U-turns: When making a U-turn, you should turn on the left turn signal in advance, and the maximum speed should not exceed 30 kilometers per hour. Do not hinder other vehicles and pedestrians driving normally.
