What are the future development trends of electric vehicles?

Electric vehicles are the future development trend of electrification. Electrification includes pure electric, hybrid, hydrogen fuel cells, and various other new energy forms. Electric vehicles are a type of new energy vehicle. Overview of new energy vehicles: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new on-board power devices), integrating advanced technologies in vehicle power control and driving, resulting in advanced technical principles, new technologies, and new structures. Others: New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid vehicles, hydrogen engine vehicles, etc. Pure electric vehicles are a type of vehicle that uses a single battery as the energy storage power source.

What is the difference between multi-link suspension and E-type multi-link suspension?

The differences between multi-link suspension and E-type multi-link suspension lie in three aspects: composition, system affiliation, and functional superiority. Different composition: Multi-link suspension consists of links, shock absorbers, and damping springs. E-type multi-link suspension refers to a suspension structure composed of three or more connecting rods. Different system affiliation: Multi-link suspension belongs to the double-wishbone suspension and multi-link suspension system, while E-type multi-link suspension is an improvement of the double-wishbone design and not entirely a double-wishbone type. Different functional superiority: Due to the numerous links, multi-link suspension can keep the wheels perpendicular to the ground, reduce body tilt, and maintain tire contact with the road. Since E-type multi-link suspension is an improved version of the double-wishbone, it is functionally superior.

What Causes the Engine to Make a Puttering Sound?

It could be caused by engine misfire or knocking. Reasons for engine idle vibration and puttering sound: Poor sealing or burning of individual valves. Severe air leakage due to poor sealing of individual valves. Carbon deposits between the valve seat and valve. Insufficient or no clearance in individual valves. In rare cases, vacuum tube detachment in power-assisted vehicles. Reasons for rhythmic puttering sound at various engine speeds: Overly rich air-fuel mixture. Ignition system misfire, severe wear of the distributor cam, contamination in individual distributor holes, leakage in individual high-voltage wires, severe leakage or insufficient gap in individual spark plugs. Mechanical issues such as perforation between individual water jackets and cylinders, water ingress in individual intake valves, poor sealing of piston rings, ring alignment seizure, piston top separation, excessive intake valve clearance, broken valve springs, lost lock pieces, or missing adjustment screws.

How many points are deducted for not holding the handbrake for three seconds in Subject 2?

Under normal circumstances, not holding the handbrake for three seconds in Subject 2 does not result in point deductions. Whether during a driving test or in daily driving, it is essential to prioritize automotive safety. Overview of Automotive Safety: Automotive safety is primarily divided into two major aspects: active safety and passive safety. Active safety involves controlling the vehicle as smoothly as possible. Whether braking and accelerating in a straight line or steering left and right, the movements should be as stable as possible to avoid deviating from the intended path while maintaining the driver's visibility and comfort. Additional Information: The scope of automotive safety technology is becoming increasingly broad and detailed, evolving toward integration, intelligence, systematization, and universalization. Strictly controlling speed during nighttime driving is a fundamental measure to ensure safety.

Why is the clutch too hard?

Clutch being too hard refers to feeling very heavy when pressing the clutch pedal. The reason for a hard clutch may be that the pressure plate spring of the clutch is too stiff. The release bearing needs to press against the pressure plate spring of the clutch. Below is a detailed introduction about automotive clutches: Overview: The automotive clutch is located inside the flywheel housing between the engine and the transmission. The output shaft of the clutch is the input shaft of the transmission. While driving, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine with the transmission, thereby cutting off or transmitting the power input from the engine to the transmission. Principle: The driving and driven parts of the clutch rely on the friction between contact surfaces, or use liquid as a transmission medium, or use magnetic transmission (electromagnetic clutch) to transmit torque, allowing temporary separation and gradual engagement between the two parts, while permitting mutual rotation during the transmission process.

What is the oil specification for Dongfeng Honda?

Dongfeng Honda's dedicated oil specifications include 0W20, 5W30, and 5W40. The original Honda oil is sourced from Nisseki oil, a joint venture between Nisseki and Great Wall. For later maintenance oil changes, you can choose brands such as Mobil, Shell, Castrol, and Total. The viscosity of the oil changes with temperature, so special attention is needed to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The second number represents the oil's kinematic viscosity at 100°C. A higher number means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing oil in a Dongfeng Honda is as follows: Wait for the engine temperature to drop and allow the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine for 30 seconds to allow the oil in the main oil passage to drain. Use a special wrench to remove the oil filter. Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add the new oil through the engine valve cover's oil filler port. Generally, fill about three-quarters of a bottle. Start the engine and let it run for 5 minutes. Check for leaks around the oil drain plug and oil filter. If there are any leaks, perform necessary repairs. After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
