Should the automatic transmission be started in N gear or P gear?

Is it normal for the idle speed to increase on its own while driving?

It is normal for the idle speed to be higher during startup. Idling can easily lead to oil burning: During idling, the throttle opening is small, and the vacuum inside the intake manifold is high, which can easily draw oil vapor into the intake manifold. Some of it deposits inside the intake manifold, forming carbon-like substances or what is called coking. Prolonged low-speed driving or idling, especially in turbocharged models, may result in a pool of oil behind the throttle in the intake manifold. However, this oil usually disappears after highway driving. Idling can easily cause carbon buildup: During idling, the air-fuel mixture tends to be richer. Therefore, prolonged idling with a richer mixture can lead to carbon buildup in the engine. Similarly, stop-and-go driving at low speeds, such as frequently accelerating and braking, can also cause carbon buildup. This is because the engine alternates between enriching and reducing fuel injection, which is prone to carbon accumulation.

What is the fuel consumption of Jetta diesel?

Jetta diesel fuel consumption is 6-8 liters per 100 kilometers. The following is a detailed introduction: 1. Introduction: Diesel is a light petroleum product, a complex mixture of hydrocarbons (carbon atoms number about 10 to 22). It is used as diesel engine fuel. It is mainly composed of diesel fractions produced by processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking; it can also be produced by shale oil processing and coal liquefaction. It is divided into light diesel (boiling point range about 180～370℃) and heavy diesel (boiling point range about 350～410℃). It is widely used in large vehicles, railway locomotives, and ships. 2. Uses: The most important use of diesel is for diesel engines in vehicles and ships. Compared with gasoline, diesel has a higher energy density and lower fuel consumption rate. Diesel has low energy consumption, so some small cars and even high-performance cars have switched to diesel.

Does Insurance Cover a Car Driven into Water?

If a car is driven into water and becomes submerged, the insurance company will not provide compensation. Below is relevant information about insurance claims: 1. Basic Introduction: Articles 22 and 23 of the Insurance Law stipulate that after an insurance incident occurs, when requesting the insurer to compensate or pay insurance benefits according to the insurance contract, the policyholder, insured, or beneficiary must provide the insurer with all available evidence and materials related to confirming the nature, cause, and extent of the loss of the insurance incident. 2. Claim Methods: Insurance companies have two methods for settling claims with policyholders after an incident occurs, based on the terms of the insurance contract: compensation and payment. Compensation corresponds to property insurance and refers to the insurer's compensation for the policyholder's loss based on the extent of damage to the insured property at the time of the incident, within the limits of the insurance amount. Insurance compensation is compensatory in nature, meaning it only compensates for the actual loss incurred, up to the value of the damaged property, and never exceeds its value.
