What to Do When a Non-Adjustable Seat Belt Chokes the Neck?

Which has a longer service life, the pushrod engine or the chain-driven engine?

Structurally speaking, the chain-driven engine is more advanced and durable. Under the same displacement, the chain-driven engine can increase power by raising the rotational speed. It features a compact size, lightweight, lower mechanical load, precise ignition, and can integrate with many advanced technologies. Therefore, high-performance, large-displacement sports bikes mostly use chain-driven engines, but they also demand higher manufacturing technology. More details are as follows: 1. The pushrod engine itself is not suitable for high rotational speeds, so to play to its strengths and avoid weaknesses, most designs feature a small cylinder bore and large stroke, increasing torque and avoiding the drawbacks of high rotational speeds. This results in strong torque at low to medium speeds, powerful acceleration, excellent climbing performance, and good practicality. Chain-driven engines can also be designed this way—simply adjusting the cylinder bore and stroke will suffice—but they cannot match the high-speed performance of chain-driven engines. 2. Generally, either toothed belts or chains are used for transmission. The advantage of toothed belts is that they do not require lubrication and operate quietly, but their lifespan is slightly shorter compared to chains. In contrast, chain-driven systems require lubrication and produce more noise, but they are highly reliable and can last as long as the engine itself. 3. The camshaft is located in the middle of the crankcase. This valve train mostly uses cylindrical timing gears for transmission, typically requiring only a pair of timing gears from the crankshaft to the camshaft, with an intermediate gear added if necessary. To ensure smooth engagement and reduce noise, helical gears are often used for timing gears. The advantage of gear transmission is its accuracy and reliability, but it tends to generate more noise.

What Causes the Noise in Car Window Regulators?

The noise in car window regulators may be caused by aging window seals or abnormal sounds from the window lifting mechanism. There are sealing strips at the bottom of the door windows. If these strips age, the friction between the strips and the window increases, leading to noise when raising or lowering the window. The car body has many sealing strips, and these rubber components can deteriorate over time. When maintaining your car, attention should be paid to the care of these rubber parts. If the sealing strips are no longer effective, they should be replaced promptly, as poor sealing may allow rainwater to leak into the car during rain.

Why is there a section in the middle that the new wiper can't reach?

New wipers may fail to reach a section in the middle due to oil film on the windshield. If it's a beam-type wiper, the issue might be insufficient pressure from the wiper arm, preventing the wiper from fully extending. It is recommended to replace the spring strip on the wiper arm or switch to a triple-section wiper. Many car owners neglect proper windshield cleaning during routine car washing and maintenance, leading to dirt and deposits on the windshield that reduce its smoothness. A wiper is a blade structure installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly, primarily used to clear rain, snow, and dust that obstruct visibility on the windshield.

How to Solve the Abnormal Noise When Car Windows Are Raised or Lowered?

Solutions for abnormal noise when car windows are raised or lowered include: 1. Tighten loose door glass at a professional repair shop; 2. Replace the sealing rubber strip of the window glass; 3. Clean debris from the guide rails. Car windows are an essential part of the vehicle body, designed to meet the needs of interior lighting, ventilation, and visibility for drivers and passengers. They are categorized into front and rear windshields, ventilation windows, heat-insulating side windows, and sunroofs. The causes of abnormal noise when car windows are raised or lowered are: 1. Loose fastening screws inside the window glass or the lifter bracket; 2. Aging sealing rubber strips of the window glass; 3. Debris in the window glass guide rails.

How often should the spark plugs be replaced on a Mazda Axela?

Mazda Axela's spark plugs should be replaced every 40,000 kilometers, using genuine Mazda brand parts. The function of spark plugs is to discharge the high-voltage pulses delivered by the ignition wires, creating an electric spark that ignites the air-fuel mixture in the cylinder by arcing across the gap between the two electrodes. The Axela is a compact car produced by Changan Mazda, featuring a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with two Skyactiv-G gasoline engines. In terms of dimensions, the car measures 4662mm in length, 1797mm in width, and 1445mm in height, with a wheelbase of 2726mm. It is a four-door, five-seater sedan.
