When the vehicle encounters extreme situations such as wading or being submerged, it is necessary to open the drainage holes to drain the accumulated water in the trunk as quickly as possible. Typically, manufacturers seal these drainage holes, which can be unscrewed or poked open when needed. Below is related information about other drainage holes in a car: 1. Air Conditioning Drainage Hole: Its function is to discharge the condensation water generated during air conditioning use out of the vehicle. If the drainage outlet is blocked, water may enter the co-pilot area through the connection, soaking items like floor mats. 2. Engine Compartment Drainage Hole: The drainage holes in the engine compartment are usually located on both sides of the front windshield wipers, generally one on each side. Since the engine compartment is a relatively open environment, sewage, fallen leaves, etc., can flow into the engine compartment along the windshield. Engineers design a water barrier at the rear of the engine compartment and along the lower edge of the windshield, with drainage holes positioned on the barrier.

Should Regular Cars Use 92 or 95 Octane Gasoline?

Whether a regular car should use 92 or 95 octane gasoline depends on the engine's operating temperature and pressure. Generally, naturally aspirated engine cars require 92 octane gasoline, while turbocharged engine cars need 95 octane gasoline. Below is an introduction to gasoline octane ratings: 1. Definition of gasoline octane rating: The gasoline octane rating represents the fuel's octane number. For example, 95 octane gasoline consists of approximately 95% isooctane and about 5% n-heptane. 2. Gasoline's anti-knock properties: Since isooctane has good anti-knock properties while n-heptane has poor anti-knock properties, a higher octane rating indicates a higher octane number, meaning the gasoline has better anti-knock performance.

What Did Ford Invent?

Ford invented the automobile. Here are some relevant introductions about Ford cars: 1. Model S: Between 1903 and 1908, Henry Ford and his engineers feverishly produced 21 different models, ranging from Model A to Model S in the alphabet. Some of these were merely experimental models that never went into production. Some had two cylinders, some had four, and one even had six; some were chain-driven, while others were shaft-driven; two models had their engines placed under the driver's seat. 2. Model T: The Model T entered the historical stage on October 1, 1908. Henry Ford called it the 'universal car.' A symbol of reliable transportation, it could keep going when other cars got stuck in muddy roads. The Model T won the hearts of millions of Americans, who affectionately called it 'Lizzie.' In its first year, production of the Model T reached 10,660 units, breaking all records in the automotive industry up to that time.
