What Causes Severe Engine Shaking During Car Startup?

Reasons for engine shaking during car startup include: severe engine carbon buildup, ignition system issues, unstable oil pressure, etc. Minor shaking is normal, but if the shaking is severe, it's necessary to visit a repair shop for inspection. Below are detailed explanations: 1. Severe Engine Carbon Buildup The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there's too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This makes starting difficult. Only when the carbon deposits become saturated with gasoline does the car start easily. After starting, the gasoline adsorbed on the carbon deposits is drawn into the cylinder by the engine's vacuum suction and burned, making the air-fuel mixture too rich. The engine's combustible mixture alternates between being too lean and too rich, causing idle shaking after a cold start. 2. Ignition System Issues Check the condition of the spark plugs, high-voltage wires, and ignition coils. Problems with the ignition system or poor performance of the spark plugs can also lead to such symptoms. 3. Unstable Oil Pressure If you've already cleaned the engine carbon deposits, cleaned the throttle body, and replaced the spark plugs but still experience shaking during startup, it's recommended to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can also cause car shaking.

Where Are Dead Mice Usually Found in a Car?

Dead mice in a car are usually found in the engine compartment, air conditioning ducts, etc. Below are the steps to handle a dead mouse in the car: 1. Inspection: Check if there is a dead mouse inside the car's air conditioning system. If so, remove the mouse first. Then turn on the air conditioning, clean the air vents, and check the intake for any other debris. It is also advisable to replace the air filter, as an excessively dirty filter not only fails to achieve its intended purpose but also causes secondary pollution to the air entering the car. To completely eliminate odors in the car, the source must be blocked. 2. Cleaning: Clean the air conditioning ducts, as a dead mouse inside can leave behind bacteria, leading to unpleasant odors. Use deodorizers or air conditioning duct cleaners to remove odors from the ducts. For external circulation, naturally ventilate by spraying evenly into the air vents, then open the windows and turn on the air conditioning for ventilation.

Why does the windshield wiper move once when the Tiguan L is turned off?

Tiguan L's windshield wiper moves once when the engine is turned off because the wiper stroke is designed with a reserved position. When hydraulic pressure, air pressure, or electrical power is lost, the wiper returns to its origin. Additionally, this design prevents the wiper from freezing to the windshield in winter and melting the wiper rubber strip due to high temperatures on the glass in summer. More information about the Tiguan L is as follows: 1. Introduction: The Tiguan L is the extended and upgraded version of the Tiguan, built on a new platform. It abandons the rounded appearance of the Tiguan, featuring a more angular and robust body design, and is equipped with full LED front and rear light groups for superior illumination. 2. Safety Features: The new Tiguan L comes standard with ESP vehicle stability system and front side airbags. The top-tier flagship model includes a pre-collision safety protection system, knee airbags, lane-keeping system, 360-degree parking camera, and HUD head-up display system. 3. Powertrain: The new Tiguan L offers two powertrain options: 330TSI and 380TSI, equipped with the third-generation EA888 turbocharged engines in 1.8T and 2.0T displacements, respectively. The former delivers a maximum output of 180 horsepower and a peak torque of 300 N•m, while the latter offers 220 horsepower and 350 N•m of torque. Additionally, the 380TSI model features Volkswagen's 4MOTION all-wheel-drive system and includes a driving mode selection function.

How is the off-road performance of the Haval Big Dog?

Haval Big Dog can handle some complex urban road conditions, but it cannot meet the requirements of high-difficulty off-roading. Here are the specific details: 1. Dimensions: The Haval Big Dog measures 4620/1890/1780mm in length, width, and height, with a wheelbase of 2738mm, which is consistent with the new Haval H6. To highlight its off-road performance, the Haval Big Dog also features a 24° approach angle, 30° departure angle, and 200mm ground clearance. 2. Configuration: The Haval Big Dog uses a front MacPherson independent suspension + rear multi-link independent suspension. The rear multi-link suspension consists of three transverse links and one longitudinal arm, so more accurately, it should be called a four-link suspension.
