What is the fuel tank capacity of the Volkswagen Polo in liters?

Why does the car jerk when warm but not when cold?

It may be due to low temperature issues. When the engine is not warm enough, more fuel is injected during cold starts to meet power requirements. Below is relevant information about car idling: 1. The function of car idling: Idling is an operating condition of a car, referring to the engine running in neutral gear. The engine speed during idling is called idle speed. Idle speed can be adjusted by modifying the throttle opening size. Idling means the engine is "producing power without doing work." When the engine is running, if the accelerator pedal is fully released, the engine is in an idling state. 2. Reasons for unstable idling: Direct causes refer to mechanical components being dirty, worn, or incorrectly installed, leading to changes in cylinder power output, resulting in unbalanced power among cylinders and causing unstable engine idling; Indirect causes refer to abnormalities in the engine's electronic control system, leading to poor combustion of the air-fuel mixture, making it difficult to balance power among cylinders and causing unstable engine idling.

What Causes the Cadillac Engine Warning Light to Illuminate?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: This includes sensors such as coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, triggering the warning light. Fuel/oil quality issues: Failure to use fuel and engine oil as specified by the manufacturer may cause engine wear, leading to warning light activation. Poor fuel mixture combustion: Incomplete combustion can cause engine carbon buildup or knocking. When detected by oxygen sensors and reported to the ECU, the warning light will illuminate. Potential causes include spark plug failure, ignition coil malfunction, fuel pump issues, or clogged fuel lines. Turbocharger problems: Issues with the intake boost system or turbocharger may trigger the warning light. The most common issue is turbocharger damage, often accompanied by oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black exhaust smoke. Intake system issues: Air intake problems may lead to engine pipe blockages, potentially triggering the warning light. A dirty air filter that hasn't been regularly cleaned can cause intake problems. Exhaust system issues: Exhaust faults can also activate the warning light. Common causes include rear oxygen sensor failure, catalytic converter problems, or exhaust camshaft/bearing issues. Leaded gasoline, certain lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions may cause catalytic converter failure. Anti-theft system malfunction: If the vehicle's electronic anti-theft system fails or doesn't properly communicate with the engine control unit, it may prevent normal engine operation and trigger the warning light. When the engine warning light illuminates, follow these steps: First, check if the engine is operating normally. If there's noticeable shaking, smoke emission, or other abnormalities (especially with a red warning light), do not restart the engine. If the engine can be started, turn off the ignition for 5-10 minutes. Then, without pressing the brake pedal, press the start button once or turn the key halfway to the ON position (without engaging the clutch). The vehicle will perform a self-diagnosis for 5-10 seconds - observe if the warning light turns off. If the light remains on, visit a service center immediately. Technicians can use diagnostic tools to read trouble codes and perform targeted repairs.

What is the best oil for CRV maintenance?

CRV maintenance should use fully synthetic oil because it provides excellent lubrication and can extend the engine's lifespan. Below is an introduction to engine oil: 1. Engine oil: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions such as lubrication, friction reduction, auxiliary cooling, sealing, leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the 'blood' of a car. 2. Key features: The engine is the heart of a car, containing many metal surfaces that move against each other under high-speed, harsh conditions, with operating temperatures ranging from 400°C to 600°C. Advanced technology can convert natural gas into crystal-clear fully synthetic base oil, which is then enhanced with proprietary power cleaning technology to create a lubricant with superior cleaning and protective performance.

What is the real reason for the idle shaking of the Buick Excelle?

Buick Excelle idle shaking is generally caused by a dirty throttle body or excessive carbon buildup in the fuel injectors. Additionally, check the working condition of the spark plugs, high-voltage wires, and ignition coils, as poor performance of the ignition system or faulty spark plug firing can also lead to such issues. The solution is to inspect whether the spark plugs have excessive carbon buildup and replace them if necessary. The main reasons for severe idle shaking in the Excelle are: 1. Throttle body: A dirty or damaged throttle body can cause idle shaking. You can first clean the throttle body, and if the problem persists, replace it. 2. Spark plugs: Non-functioning spark plugs can lead to misfiring and idle shaking. Inspect the spark plugs and ignition module for faults. 3. Engine and transmission: Aging or cracked rubber components inside the mounts can no longer absorb the engine's vibrations, resulting in idle shaking issues.

What does the car belt 6pk1065 represent?

PK indicates the model of the multi-ribbed belt, and 6PK means the PK model belt has 6 ribs. 1065 represents the length. More relevant information is as follows: 1. Function: The car belt serves as a connecting link between the preceding and the following. The upper part connects to the timing wheel of the engine cylinder head, and the lower part connects to the timing wheel of the crankshaft; the timing wheel is connected to the camshaft, which has cams. Its contact point is the small rocker arm, and the rocker arm generates pressure through the power brought by the timing belt, playing a lifting role. 2. Advantages: Car belts have been used in engines for a long time, with mature technology, lower cost, and less noise, but they require regular inspection and maintenance, generally needing replacement every 50,000 to 100,000 kilometers. Timing chains have significant advantages such as compact structure, high power transmission, high reliability and wear resistance, and lifetime maintenance-free, but compared to traditional timing belts, their noise is generally slightly louder.
