If the engine warning light is on and the car shakes, you should call a 4S shop or a professional auto repair shop for help, request a tow truck or wait for rescue, and avoid risking continued driving. Reasons for the engine warning light being on and the car shaking: The ignition system malfunctions, with issues in the working conditions of spark plugs, high-voltage wires, and ignition coils, leading to poor ignition system performance; An overly rich air-fuel mixture in the cylinders may cause symptoms such as knocking and shaking. The engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, originated in the UK, and it can refer to both the power generation device and the entire machine including the power unit.

I just encountered a situation two days ago where the engine malfunction light came on and the car was shaking badly, which was really scary. That time, while driving to the supermarket, the car suddenly started shaking like it was having a fit, with the warning light flashing. The cause could be an issue with the ignition system, worn spark plugs, or aging coils, leading to uneven combustion of the air-fuel mixture; it could also be insufficient fuel pump pressure or clogged fuel injectors. Safety first, I immediately pulled over, turned off the engine, turned on the hazard lights, and called a tow truck to take the car to the repair shop. They used a diagnostic tool to read the fault codes and quickly identified it as a spark plug issue. After replacing them, the problem was fixed. Don’t ignore minor issues when driving; schedule regular mileage checks for ignition components to avoid a lot of trouble.

Is it necessary to change the engine oil if a motorcycle has been left unused for half a month?

It is necessary to change the engine oil. Engine oil stored in its original unopened bottle can last up to 5 years without issues. However, once added to a motorcycle, it begins to oxidize, hence the need for replacement. Choose engine oil with moderate viscosity: Using engine oil with excessively high viscosity in winter can easily cause damage to the vehicle. It is not advisable to blindly opt for high-viscosity oil. On the other hand, oil with too low viscosity may fail to adequately separate stationary and rotating parts, leading to rapid wear of bearings. Therefore, engine oil with moderate viscosity should be selected. More expensive engine oil is not necessarily better: The notion that more expensive engine oil is better is incorrect. Different motorcycle models have varying engine structures and are prone to different types of issues. Therefore, it is essential to follow the vehicle's maintenance manual to select the appropriate engine oil.

What is the voltage of new energy vehicle batteries?

Low-speed electric vehicle battery packs have voltages of 48V, 60V, and 72V, while high-speed electric vehicle battery packs generally have voltages ranging from 380V to 560V. Normal battery voltage: The normal battery voltage is between 11.8V and 12.8V. After starting, the battery voltage ranges between 13.2V and 14.8V. As long as the voltage during startup is not lower than 11V, it is considered normal. Both excessively high and low battery voltages can have certain impacts. Precautions for battery voltage: Regularly check the battery's usage condition. If the battery voltage drops below 10.8V, it needs to be charged promptly.

What Level of Autonomous Driving Does Tesla Belong To?

Tesla's autonomous driving technology belongs to Level 2 (L2). Level 2 autonomous driving is not fully autonomous and requires the driver to remain attentive. Below is an introduction to the levels of autonomous driving technology: 1. Level 0: No automation. The driver must control all mechanical and physical functions of the vehicle at all times, with only alarms as assistance. 2. Level 1: The driver operates the vehicle, but individual devices can sometimes assist, such as Electronic Stability Program (ESP) or Anti-lock Braking System (ABS), which help with driving safety. 3. Level 2: The driver primarily controls the vehicle, but the system offers partial automation to significantly reduce the operational burden, such as Adaptive Cruise Control (ACC) combined with automatic following and lane departure warning, while the Automatic Emergency Braking (AEB) system integrates blind-spot detection and partial collision avoidance technology. 4. Level 3: The driver must be ready to take control at any time. During autonomous driving assistance, such as when following another vehicle, the driver can be temporarily relieved of operation, but when the car detects a situation requiring driver intervention, it will immediately return control to the driver, who must take over to handle situations the system cannot manage.

What is the oil capacity of Kawasaki 400?

Kawasaki 400 oil capacity is 1.6L without oil filter replacement, and 2L with oil filter replacement. Definition of engine oil: Engine oil, also known as motor lubricant (English name: Engine-oil), serves multiple functions including lubrication, friction reduction, auxiliary cooling, sealing, rust prevention, corrosion protection, and shock absorption. It is often referred to as the "blood" of automobiles. Composition of engine oil: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties. Additives are used to compensate for and improve any deficiencies in the base oil's performance, while also imparting new characteristics, making them an essential part of lubricating oil.

How Long After Production Date is a New Energy Vehicle Considered Inventory Stock?

Inventory stock generally refers to vehicles that remain unsold for more than three months after leaving the factory. Definition of inventory stock: Inventory stock typically denotes vehicles that have remained unsold for over three months after manufacturing completion and factory release. Since the automotive industry emphasizes timeliness, new vehicles normally complete the journey from production to customer delivery within one to two months. Those exceeding three months or longer are generally classified as inventory stock. Potential issues with inventory stock: After leaving the factory, various fluids, electronic components, batteries, rubber seals, and tires in new vehicles may undergo prolonged storage without periodic inspection and maintenance, making them prone to moisture damage and aging. Only a handful of dealerships implement regular inspection and maintenance measures—though the cost isn't high, it consumes manpower and time. Some 4S stores even park inventory vehicles outdoors, exposing them directly to sun, wind, and rain. For vehicles stored excessively long without proper warehouse management, the aging of electronic components and rubber products often goes undetected without professional equipment. Many long-term inventory vehicles also suffer from fuel or battery depletion issues.

Is No Response When Starting the Engine Caused by Spark Plugs?

No response when starting the engine could be caused by spark plugs, but it may also result from carbon buildup in the car or fuel injector leakage. Carbon Buildup in the Car: This failure to start is primarily due to excessive carbon deposits in the idle speed motor, intake tract, intake valves, and combustion chamber. When there is too much carbon buildup or dirt in the intake tract, the cross-sectional area of the air passage changes, leading to an overly rich or lean air-fuel mixture. This causes abnormal combustion or engine shaking after starting, and in severe cases, the engine may fail to start at all. Fuel Injector Leakage: No response when starting could also be due to issues with the fuel injectors, such as leakage or excessive carbon buildup, resulting in a lean air-fuel mixture during startup and making it difficult to start the engine. Additionally, if the charcoal canister or the charcoal canister solenoid valve malfunctions, it can also lead to difficulties in starting the engine.
