It can lead to carbon deposits and affect engine performance. Here are the related introductions: 1. Carbon deposit formation: Excessive oil can enter the combustion chamber through the gap between the cylinder and piston, burning and forming carbon deposits. These deposits can increase the engine's compression ratio and the probability of knocking. 2. Increased fuel consumption: Excessive oil also increases the stirring resistance of the crankshaft connecting rod, leading to higher fuel consumption. It can also increase internal engine pressure, causing oil leakage from engine seals. There are two marks on the oil dipstick, and the oil level is best kept between the highest and lowest marks. It is necessary to consider your driving habits and performance requirements for the vehicle when adjusting the oil product used.

Should I Top Up or Replace the Antifreeze When It's Low?

Upon discovering low antifreeze levels, the first step is to verify whether there is a leak in the engine's cooling system. After a preliminary inspection, you can proceed to top it up. If there is a leak or the level keeps dropping, it's advisable to visit a repair facility for inspection and maintenance promptly. During the antifreeze maintenance and inspection process, check if the antifreeze has deteriorated or changed color. Typically, antifreeze should be replaced every 2 years or 40,000 to 60,000 kilometers, depending on the vehicle's actual condition. Antifreeze prevents the coolant from freezing during cold winter parking, which could otherwise crack the radiator or damage the engine cylinder block or head. It's essential to use antifreeze year-round.

What is the working principle of a torque sensor?

Working principle of torque sensor: It uses strain gauge electrical measurement technology to form a strain bridge on an elastic shaft for torque measurement. Application scope of torque sensor: 1. Detection of output torque and power of rotating power equipment such as motors, engines, and internal combustion engines; 2. Detection of torque and power of fans, water pumps, gearboxes, and torque wrenches; 3. Can be used to manufacture viscometers; 4. Can be used in process industries and flow industries. Precautions for installing torque sensors: 1. Do not operate with electricity, and never directly strike or collide with the sensor; 2. The fastening bolts of the coupling should be tightened, and a protective cover should be added outside the coupling to avoid personal injury.

What Causes the Rattling Noise in a Car Door Limiter?

Door limiter rattling noise is caused by wear and tear of the limiter. Applying some oil to the limiter for lubrication can resolve the issue. Below is the related introduction: Introduction to Door Opening Limiter: Commonly referred to as the limiter, it is a device that restricts the rotation of the door when subjected to a certain force. Function of the Door Opening Limiter: It limits the extent to which the door can open. On one hand, it restricts the maximum opening of the door to prevent it from opening too wide. On the other hand, it keeps the door open when needed, such as when the car is parked on a slope or during windy conditions, preventing the door from closing automatically.

How to Remove Crankshaft Bolts with Primitive Methods?

Insert two steel bars into the holes, then use a pry bar to leverage the two steel bars to loosen the bolts. Alternatively, measure the hole distance and weld an F-shaped wrench. Below is an introduction to the crankshaft: 1. Introduction: The crankshaft is the most important component in an engine. It receives the force from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other engine accessories. 2. Function: The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertial forces, and reciprocating inertial forces, causing it to bear bending and torsional loads. 3. Requirements: The crankshaft must have sufficient strength and stiffness, with journal surfaces that are wear-resistant, operate uniformly, and have good balance.
