How to Choose Oil for Manual Transmission?

Do the small steel balls in the axle increase or decrease friction?

They reduce friction. The steel balls installed in the axle convert sliding friction into rolling friction, thereby lowering the friction during power transmission and improving the efficiency of mechanical power transfer, which helps increase the speed of the vehicle. The steel balls in the axle are also known as ball bearings, steel shots, marbles, or rolling balls, and are used in mechanical rotating devices such as bearings, lead screws, and slide rails. More details are as follows: 1. Basic structure of rolling bearings: Rolling bearings generally consist of an inner ring, outer ring, rolling elements, and a cage. The inner ring fits with the shaft and rotates together with it, while the outer ring fits with the bearing housing to provide support. 2. The rolling elements are evenly distributed between the inner and outer rings by the cage. Their shape, size, and quantity directly affect the performance and lifespan of the rolling bearing. The cage ensures even distribution of the rolling elements, prevents them from falling out, and guides their rotation to facilitate lubrication.

What type of engine oil should be used for the Haval H6 Coupe?

Haval H6 Coupe is recommended to use semi-synthetic engine oil with a viscosity of 5W-40, or higher-grade full-synthetic engine oil. The type of engine oil used in a vehicle should be determined based on the vehicle's performance and the type of engine it is equipped with. The Haval H6 Coupe is powered by a 1.5T turbocharged engine. Below are specific details about this engine: 1. The 1.5T turbocharging indicates that the vehicle's displacement is 1.5 liters, and the engine's air intake method is turbocharged. 2. The 'T' in 1.5T stands for Turbo, which represents turbocharging. Turbocharging (Turbo-Boost) is a technology that uses exhaust gases generated by internal combustion engine operation to drive an air compressor (Air-compressor). 3. Turbocharged engines available in the market rely on turbochargers to increase the engine's air intake. A turbocharger (Turbo) is essentially an air compressor. It uses the exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage), which in turn drives the coaxial impeller (located in the intake passage). The impeller then compresses fresh air delivered through the air filter pipe and sends it into the cylinders.

What Causes the Dripping Sound Under the Chassis After Parking?

Reasons for the dripping sound under the chassis after parking: 1. Cooling sound of the three-way catalytic converter: The normal operating temperature of the three-way catalytic converter is 400-800°C. After the engine is turned off, the three-way catalytic converter gradually stops working, and its temperature decreases, causing the internal metal components to expand and contract due to heat, resulting in abnormal noises. 2. Cooling sound of the exhaust pipe: During cold idling, the exhaust pipe can reach a temperature of over 200°C. Under high load or when the mixture burns in the exhaust pipe, the temperature can be even higher. Therefore, the exhaust pipe also expands and contracts due to heat, producing abnormal noises, often originating from the front end or flexible joint of the exhaust pipe. 3. Cooling sound of the turbocharger: Normally, the exhaust gas temperature can reach 600-700°C, and the rapid rotation and friction of the turbocharger generate additional heat. After the engine is turned off, the heat-induced expansion and contraction become very noticeable, leading to abnormal noises.

What is the fuel consumption of the nk250?

The fuel consumption of the nk250 motorcycle is 2.8 liters per 100 kilometers. The fuel consumption of a motorcycle is not only related to the motorcycle itself but also to the driver's driving habits, and it is also closely related to the driving conditions. The reasons for the increasing fuel consumption of the vehicle are as follows: 1. Fuel consumption fluctuations due to temperature influence: Generally, in winter when the temperature is low, fuel consumption tends to increase, almost comparable to the fuel consumption when using air conditioning in summer. This is because the low temperature causes the engine to dissipate more heat. 2. The vehicle has not been maintained for a long time: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil results in poor lubrication, causing increased resistance in various moving parts of the engine, which requires more energy to overcome, thus increasing fuel consumption. 3. The spark plugs need to be replaced: Spark plugs are often overlooked. Even if they can still function, worn spark plugs may cause delayed ignition due to insufficient ignition energy, missing the optimal ignition timing.

Which gear is used in the Subject 3 test?

Subject 3 test gear requirements are as follows: 1. When using first or second gear: The driving distance cannot continuously exceed 500 meters, otherwise it will be judged as a test failure. 2. When using third gear: Accelerate to reach 20 km/h before switching to third gear. 3. When using fourth gear: When the speed exceeds 30 km/h, you can switch to fourth gear. The content of the Subject 3 road driving skills test includes: vehicle preparation, light simulation test, starting, straight-line driving, gear shifting operation, lane changing, parking by the side of the road, going straight through intersections, turning at intersections, meeting vehicles, overtaking, making U-turns, and night driving.

Can Seat Heating Function Be Added Afterwards?

Seat heating function can be added afterwards. Seat heating utilizes electric heating wires inside the seat to warm the interior, transferring heat to the occupant through thermal conduction, thereby improving discomfort caused by excessively cold seats after prolonged parking in winter. Below is an introduction to seat heating: 1. Basic structure of seat heater: The lower layer consists of a non-woven fabric, with heating wires arranged on it and fixed in place with adhesive tape. A knitted fabric covers the adhesive tape and is stitched with knitting thread into a shape resembling the heated area of the seat, then sewn into the seat cover. 2. Working method of seat heater: The backrest heater is connected to the power supply of the seat cushion heater via connectors. The seat cushion heater power supply is connected to the dashboard wiring harness through connectors, then linked to the battery power via the seat heating switch, fuse, and ignition switch.
