What does HEV hybrid mode mean?

HEV stands for Hybrid-Electric-Vehicle, which is a hybrid-powered car. Below is the relevant introduction: 1. Definition of HEV: HEV is a compromise between traditional cars and fully electric vehicles. It utilizes both the internal combustion engine of traditional cars (which can be designed smaller) and the electric motor (PMSM or asynchronous motor) of fully electric vehicles (Purely-Electric-Vehicle) for hybrid driving (including the battery and inverter components), reducing the demand for fossil fuels and improving fuel economy, thereby achieving energy-saving, emission-reduction, and alleviating the greenhouse effect. Toyota Prius and Honda Insight are two major players in HEV production. 2. Hybrid method: Hybrid power means the car uses both gasoline and electric power for driving. The advantage is that when the vehicle starts and stops, it is only driven by the electric motor. The engine does not work until a certain speed is reached. Therefore, the engine can always be kept in the optimal working condition, with good power performance and very low emissions. Moreover, the source of electric energy is the engine, so only refueling is needed.

What type of axle is used in railway vehicles?

The wheel axle of a train carriage is a spindle. Here are the specific details: 1. Introduction to axles: An axle is a cylindrical object that passes through the middle of a bearing, wheel, or gear, though a small portion may be square-shaped. It is a mechanical component that supports rotating parts and rotates with them to transmit motion and bending moments. Generally, it is a metal rod with varying diameters along its length. Parts that perform rotational motion in machinery are mounted on the axle. 2. Torsional stiffness verification of the axle: The torsional stiffness verification of the axle calculates the torsional deformation during operation, measured by the angle of twist per meter of axle length. Excessive torsional deformation can affect the performance and operational accuracy of machinery. For example, excessive twist in the camshaft of an internal combustion engine can disrupt the correct opening and closing timing of valves.

Where is the Focus's air filter located?

The air filter for the Focus sedan version is located under the glove compartment on the passenger side, while for the hatchback version, it is on the right side of the accelerator pedal. Remove the cover to see it. For newer models of the Focus, you need to remove the accelerator pedal to access it. There are several screws next to the accelerator pedal; remove them and take off the pedal to reveal the air filter cover. Then, remove the air filter cover to see the air filter. The Focus is a Ford A-segment family car with body dimensions of 4480mm in length, 1840mm in width, and 1500mm in height, with a wheelbase of 2640mm. The Focus features a fully independent rear suspension system, providing smooth cornering performance, and is equipped with double ball joints to effectively eliminate vibration noise from the tires.

Does the car transfer require the owner to be present?

Car transfer does not require the owner to be present, but the owner needs to prepare a power of attorney to authorize an agent to handle the transfer on their behalf. The following documents are mandatory: power of attorney, original owner's ID card, new owner's ID card, original and duplicate of vehicle license, purchase tax certificate, road maintenance fee receipt, vehicle and vessel tax payment certificate, vehicle registration certificate, vehicle inspection report for criminal investigation, and insurance policy. Some documents must be original copies, and photocopies are not acceptable. Car transfer refers to changing the name of the vehicle owner. The necessity of transfer: The transfer process legally completes the transfer of vehicle ownership, ensures the legality of the vehicle's origin, and clarifies the division of responsibilities between the buyer and seller related to the vehicle.

What is the recommended tire pressure for sedans?

The recommended tire pressure for sedans typically ranges between 2.2 to 2.5 bar. Different vehicle models have varying weights, and thus their standard tire pressures may differ. When tire pressure is too low: Tire wear accelerates, increasing the risk of blowouts and raising fuel consumption. When tire pressure is too high: Tire grip decreases and wear accelerates, while braking performance weakens. Driving with unbalanced tire pressure among the four tires can cause the vehicle to pull to one side and accelerate the wear of the under-inflated tire, reducing its lifespan. Important notes for tire pressure measurement: Cold and hot tires have different pressures. Special attention should be paid during measurement, as hot tires typically have about 0.2 bar higher pressure than cold tires. Additionally, tire pressure should be adjusted seasonally. Due to significant temperature differences between winter and summer causing thermal expansion and contraction, winter tire pressure should be slightly higher than in summer. During winter, adjust the tire pressure based on the standard pressure for your vehicle's tires, typically increasing it by about 0.2 bar.
