Corolla engine shaking and making abnormal noises when the air conditioning is turned on is due to the metal friction sound emitted when the compressor electromagnetic clutch engages, or the squeaking sound caused by excessive force on the air conditioning belt. Another reason could be issues with the ignition system, leading to insufficient car power. Reasons for problems with the car ignition system: Spark plug failure, delayed ignition, or premature ignition. Reasons for insufficient car power: Insufficient fuel supply, faults in the ignition system, too much or too little lubricating oil in the crankcase. Incomplete combustion of the combustible mixture due to various reasons, leading to excessive carbon deposits in the combustion chamber, resulting in poor heat dissipation and engine overheating due to increased load.

What is the top speed of the CFMoto NK250?

CFMoto 250NK has a top speed of approximately 150 kilometers per hour. Here is a detailed introduction about vehicle speed: 1. Overview: Vehicle speed refers to the distance a vehicle travels per unit of time, abbreviated as speed, commonly measured in kilometers/hour or meters/second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in traffic flow theory research. 2. Others: Vehicle speed can also generally refer to motor vehicle speed. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Spot speed is the instantaneous speed of a vehicle passing a specific point on the road. Design speed is the speed set to determine the design indicators of various geometric elements of the road and to ensure their coordination.

Is it acceptable for the car body to touch the line during a right-angle turn?

When taking the right-angle and curve driving tests, touching the line with the car body does not result in point deductions. Below is relevant information about the driving test: 1. Definition of simulation fee: The simulation fee and venue fee refer to the costs required for a simulated test at the examination site. During the process of obtaining a driver's license, apart from the registration fee, simulation fee, and venue fee, there are no other costs. However, the decision to take or not take the simulated test is entirely up to the individual; you can choose to simulate or not. 2. Driving test: Applicants for a motor vehicle driver's license must pass the following four test subjects: Subject One - Road Traffic Safety Laws, Regulations, and Related Knowledge Test; Subject Two - Site Driving Skills Test; Subject Three - Road Driving Skills Test; and Subject Four - Safe and Civilized Driving Knowledge Test. The test sequence proceeds from Subject One to Subject Four in order, and applicants are only allowed to take the next subject after passing the previous one.

Are there any legally roadworthy RX7s in China?

Currently, there are no legally roadworthy RX7s in China, as this model is a right-hand drive vehicle, which does not comply with China's driving regulations. The RX-7 is a sports car under the MAZDA brand, a representative model among Japanese sports cars. It features a traditional FR (front-engine, rear-wheel-drive) configuration, equipped with a five-speed manual transmission, and its integrated rear light cluster is the most distinctive feature of the car. Below is extended information on left-hand drive and right-hand drive vehicles: 1. Main differences between left-hand drive and right-hand drive vehicles: The primary distinction lies in the A-pillar blind spots. For someone accustomed to driving a left-hand drive vehicle, switching to a right-hand drive vehicle would feel like driving from the passenger seat. The blind spot shifts from the left to the right, causing significant discomfort. This is one of the most noticeable differences for drivers, aside from the handling variations. 2. Precautions: You can start the vehicle first, but pay attention to gear shifting—note that first gear is on the left. Drive slowly and adjust to the unfamiliarity by adapting to the front and side rearview mirror views.

What is the difference between single axle and double axle?

The main differences between single axle and double axle are as follows: 1. Different load capacities: Single axle vehicles have a relatively small load capacity with 4 wheels at the rear; Double axle vehicles have a larger load capacity with 8 wheels at the rear. 2. Different drive axles: A single axle vehicle has only one rear axle, which is definitely the drive axle; A double axle vehicle has two axles - the middle axle and the rear axle. The middle axle is the drive axle, while the rear axle can be either a drive axle or a tag axle. Additional information: The axle, also known as the shaft, is connected to the frame (or load-bearing body) through the suspension, with wheels installed at both ends. Its function is to transmit forces and moments in all directions between the frame (or load-bearing body) and the wheels. Based on the role of the wheels on the axle, axles are classified into drive axles, steering axles, steering drive axles, and support axles, with steering axles and support axles both belonging to the category of non-drive axles.

Which Honda CR-V models and years are affected by engine oil dilution?

Honda CR-V engine oil dilution issue primarily affects models equipped with the 1.5T engine, meaning any Honda vehicle using this powertrain may experience or be at risk of oil dilution. The affected models include the new CR-V, Civic, Avancier, and UR-V, with the production year being 2017. Below is an extended introduction: 1. Causes of oil dilution: Oil dilution is mostly caused by incomplete fuel combustion or coolant leakage, such as clogged air filters, faulty fuel injectors, spark plug issues, high-voltage coil failures, low engine temperature, or poor fuel quality. 2. Introduction to Honda CR-V: The Honda CR-V is a classic urban SUV model produced by Dongfeng Honda. The 2015 CR-V features a sporty and stylish exterior design, paired with Michelin Latitude series SUV tires, delivering excellent handling performance. The domestically produced CR-V has no significant differences in appearance, performance, or main parameters compared to the imported version. It is equipped with a newly developed 2.0L DOHC i-VTEC engine by Honda, representing the brand's latest technology.

How Many Degrees Does Each Mark on the Temperature Gauge Represent?

Each small mark on the car temperature gauge represents 15 degrees, while each large mark represents 30 degrees. Here are the detailed explanations: 1. Car Temperature Gauge: The 'C' on the car temperature gauge stands for 60 degrees, and the red 'H' mark represents 110 degrees. The span from 60 to 110 degrees helps estimate the approximate temperature indicated by the gauge. 2. Possible Reasons for Rising Car Temperature: If the temperature gauge pointer reaches above the red line, it indicates a problem with the car engine's cooling system. Continuing to drive under such conditions may lead to engine damage. The direct cause is poor engine cooling. For example, small-displacement cars climbing hills with air conditioning on in summer increase the engine load. Prolonged use without cleaning the internal and external dirt of the radiator affects the cooling water circulation and heat dissipation. Damaged fans or other cooling components failing to assist the radiator in time can cause the cooling water in the radiator to reach boiling point.
