Is Higher or Lower Engine Oil Viscosity Better?

Introduction to engine oil viscosity is as follows: 1. Low viscosity: The lower the engine oil viscosity, the thinner the oil film, the better the fluidity, and the relatively smaller resistance to engine operation; however, its ability to resist shear under high temperature and pressure is weaker. The smaller the number before W, the lower the viscosity at low temperatures, the better the low-temperature fluidity, and the lower the applicable minimum temperature. It is easier to start at low temperatures, and the oil can quickly reach the friction surface after starting, helping to reduce engine wear at low temperatures. 2. High viscosity: The higher the engine oil viscosity, the thicker the oil film, the weaker the fluidity, and the relatively greater resistance to engine operation, but its ability to resist shear under high temperature and pressure is better, helping the friction pair resist wear under greater pressure. The larger the number before W, the higher the viscosity at low temperatures, the worse the low-temperature fluidity, and if used at temperatures beyond its capability, it may result in failure to start. Users should choose engine oil viscosity based on their vehicle's requirements.

What to Do When a Truck Consumes Excessive Urea?

The situation where a truck consumes excessive urea is as follows: 1. Vehicle urea plays a critical role in vehicle power, fuel consumption, etc. If diesel engine exhaust fluid is loaded or urea solutions of insufficient purity and poor quality are used, it can cause the vehicle's engine to automatically decelerate. At the same time, poor-quality diesel engine exhaust fluid can pollute the catalyst in the SCR catalytic reaction tank, leading to damage to the components of the after-treatment system. 2. Urea is added for diesel engine vehicles because diesel engines emit harmful nitrogen oxide gases, causing environmental pollution. Inhaling these exhaust gases can harm human health. To reduce this hazard, urea is added to diesel engine vehicles. It has a catalytic function, reacting chemically with nitrogen oxides to convert them into nitrogen and water, which are then expelled. Moreover, urea is consumed whenever the vehicle is in motion, so it needs to be replenished regularly. 3. Qualified urea solution is synthesized from NOX with 32.5% ultra-pure urea and pure water. Vehicle urea solution, through selective catalytic reduction with NOX products, converts them into nitrogen, oxygen, and water, thereby reducing nitrogen oxide emissions. It is suitable for all Euro IV and Euro V emission diesel engine SCR systems.

What tires does the FAW Senya R7 use?

FAW Senya R7 uses Linglong tires. The Senya R7 is a compact SUV launched by FAW Jilin. In terms of body dimensions, its length, width, and height are 4305mm, 1780mm, and 1655mm respectively, with a wheelbase of 2600mm. In terms of power, the Senya R7 is equipped with 1.6L and 1.5T engines, with maximum power outputs of 85kw and 110kw respectively, and peak torques of 155nm and 220nm. Externally, it features a large-mouth grille design paired with slender headlight clusters on both sides, along with L-shaped fog light designs on the lower bumper, which enhances the vehicle's modern appeal. Inside, the FAW Senya R7 has a more rational overall layout, with a floating central control screen, trapezoidal air vents, and a rotary knob-style air conditioning control panel arranged from top to bottom, complemented by chrome trim for detailed accents.

What to Do When the Braking System Fails?

Solutions for braking system failure are as follows: 1. Braking system failure may be caused by severely worn brake pads. Brake pads come in two types: those with sensor lines and those without. Those with sensor lines will automatically complete the circuit when the brake pads wear down to their limit, triggering the fault light. 2. In the case of worn brake pads, the vehicle can still be driven for several hundred kilometers, but it is not recommended to continue driving. Worn brake pads can lead to longer braking distances, softer braking, increased noise, and damage to the brake discs. It is best for vehicle owners to develop the habit of regularly replacing brake pads, choosing the replacement cycle based on their driving habits and road conditions. 3. Another possible cause is low brake fluid level. Brake fluid plays a crucial role in the vehicle's braking system. When the driver presses the brake pedal, the force applied is transmitted by the master cylinder piston through the brake fluid to the wheel brake cylinders, causing the brake pads to contact the wheels and stop the vehicle. Insufficient brake fluid will also result in noticeably reduced braking force, and in severe cases, complete loss of braking power.

What does it mean when the fuel gauge shows a yellow light?

When the yellow light on the car's fuel gauge comes on, you can still drive approximately 40 kilometers. Here are some methods to reduce fuel consumption: 1. Enhance car maintenance: The adjustment and maintenance of the car affect engine performance and driving resistance. Car owners should regularly visit auto repair shops for routine maintenance, such as checking tire pressure, wheel alignment, adjusting the gap between brake pads and brake drums, lubricating various points on the car chassis, changing engine oil on schedule, and inspecting filters. 2. Avoid prolonged engine idling: The fuel consumption of an idling engine is much higher than during normal driving. Therefore, if the vehicle is not moving for a long time, such as when parked and waiting, it is best to turn off the engine. During cold starts, warming up the car should not exceed one minute; maintaining a few minutes of low-speed driving is sufficient. 3. Avoid sudden braking and acceleration as much as possible: A smooth and steady driving style is the most fuel-efficient. During the starting phase, try to avoid stomping on the accelerator. The correct method is to accelerate smoothly and maintain a constant speed once a certain speed is reached.

At What Engine RPM is Fuel Most Efficient?

Generally, for fuel-injected vehicles, maintaining an engine RPM between 2200-2500 while driving is considered most fuel-efficient. Below are some methods to save fuel: 1. Regularly check the tire system: Insufficient tire pressure increases friction between the tires and the ground, leading to higher fuel consumption. Therefore, it's essential to frequently check tire pressure, as different vehicle models and tires have varying standard pressure levels. Additionally, severely worn tires can cause slippage and increase fuel consumption, necessitating replacement when needed. 2. Regularly inspect the braking system: Some vehicles may experience slight brake drag, effectively increasing the vehicle's load during driving and raising fuel consumption, so periodic checks are crucial. 3. Perform regular maintenance and replace parts: Air filters, gasoline filters, and oil filters need replacement every 5,000 kilometers or more, as a clogged air filter reduces air intake, leading to incomplete gasoline combustion and decreased fuel efficiency. Wear on the clutch plate and clutch pressure plate, as well as prolonged use of spark plugs, can also result in increased fuel consumption, so these should be replaced periodically.
