A faulty tensioner can lead to the following consequences: 1. When accelerating, it may cause engine shaking, difficulty in ignition, and in severe cases, failure to start; 2. It may deform the valves, causing damage to engine components, and in worse cases, lead to seizing, preventing the belt from transmitting power normally and resulting in vehicle breakdown; 3. Once the tensioner is damaged, it will no longer be able to adjust the belt tension, causing abnormal engine noises, timing misalignment, ignition and valve timing disorders, which will affect the normal operation of the vehicle. The method for removing the tensioner is: Drive the vehicle onto a lift, disconnect the battery, remove the hose connector bracket, insert the tool into the special opening of the belt tensioner, then use a wrench to turn the automatic belt tensioner clockwise and release the engine accessory belt. Loosen the fixing screws according to the belt tensioner to be removed.

What is the fuel consumption of a 50kW generator?

Generally, the fuel consumption of diesel engines is 200-250 grams per kilowatt-hour. The larger the power of the diesel engine, the lower the fuel consumption. Conversely, the smaller the power, the higher the fuel consumption. For a 50kW diesel generator, the fuel consumption can be calculated based on 200-250 grams per kilowatt-hour. The main factors affecting fuel consumption are as follows: Engine: This is an inherent factor affecting fuel consumption. From a purely technical perspective, direct injection is an excellent technology that significantly improves fuel combustion efficiency, but it places higher demands on the engine's fuel supply system and cylinder materials. Transmission: Here, the transmission refers to the automatic transmission. The engine and transmission form the simplest power output system, so the design of the transmission also directly affects fuel consumption. Driving habits: This is an acquired factor affecting fuel consumption and also the most significant one. The same vehicle will have different fuel consumption under different driving conditions.

Can old tires be deducted when replaced?

Yes, but the price will be based on the value of waste materials. Old tires are generally recycled by auto parts markets. Waste tire recycling: Tire vendors collect various used tires from tire repair shops, waste collection stations, and drivers. After centralized collection and sorting, they sell them to local or upstream merchants as needed. The upstream merchants (such as retreading, hot patching, sleeve tire, or cord fabric processing points) process them into usable tires and sell them back to tire repair shops or drivers. The upstream merchants (waste tire processors, including segmentation: crushing, grinding, and oil refining) further process the tires and sell them to higher-level merchants. Notes on old tire disposal: Tire retreading is a technology that repairs and processes worn or otherwise damaged tires to restore their usability. Adding catalysts and other methods to refine waste tires into oil involves heating and pressurizing waste tires to extract fuel. If simple and cheap equipment is used, this technology can easily cause secondary pollution.

How to Handle Running a Red Light in Another City?

How to handle running a red light in another city: Running a red light in another city will result in a fine and a deduction of 6 points. The determination of running a red light requires three photos: the vehicle crossing the stop line, the vehicle moving to the center of the road, and the vehicle entering the stop line on the opposite side of the intersection. Only when all three photos are present is it considered running a red light. Situations that can eliminate the penalty points and fine for running a red light include: 1. Yielding to emergency vehicles such as police cars, ambulances, or fire trucks on duty, leading to running a red light; 2. Being rear-ended by another vehicle, causing you to run a red light; 3. Malfunctioning or conflicting traffic signals with on-site police directing traffic, resulting in running a red light; 4. Accidentally running a red light due to being blocked from view by a large vehicle in front.

Where is the air intake of Suzuki UU125 located?

Suzuki UU125 does not have an air intake, so there is no such thing as the location of the air intake for this model. Below is some relevant information about the Suzuki UU125: 1. Exterior: Compared to the UU125i, the new model features a more angular design, with numerous fold lines and geometric-shaped outer panels replacing the previously gentle and soft 'little lamb' look, reflecting a sporty feel. The currently popular V-shaped front face makes the two headlights look less cute. The headlights use halogen light sources, but with sufficient power, the lighting effect is not bad. 2. Overview: In terms of configuration, it has front upright shock absorbers and a rear single-sided independent shock absorber. For braking, the base model comes with front and rear drum brakes, while the higher-end version features a front disc brake and rear drum brake. In terms of power, similar to the YY125i, it has a maximum power of 6.9kW and a peak torque of 9.8N.m.
