What is an STI car?

STI is not a car brand. To be precise, STI is an organization under Fuji Heavy Industries' Subaru automobile company, namely the Subaru Sports Modification Department. Generally, the models modified by this department are collectively referred to as STI, representing high-performance versions of civilian vehicles. Below is relevant information: 1. Usually, when people refer to STI, they mean the Impreza. Back then, Subaru used modified Imprezas to replace the older Legacy models to enhance competitiveness in the WRC, subsequently becoming strong contenders for championships in WRC events. The most famous and regarded as a modification classic among Impreza STIs is the 1998 22B, Subaru's only two-door sedan. 2. STI is affiliated with Fuji Heavy Industries Ltd. in Japan, and its role is to support Subaru's participation in global motorsport events. Among these, the World Rally Championship (WRC) is STI's main stage. The competition-spec engines for Subaru WRX are all assembled and tuned by STI before being shipped to Subaru's racing headquarters in the UK.

I've been into car modifications for over a decade and know STI inside out. STI stands for Subaru Tecnica International, the high-performance division of Subaru. The most iconic model is undoubtedly the Subaru WRX STI, with its EJ20 turbocharged four-cylinder engine pumping out over 300 horsepower. Paired with the signature symmetrical all-wheel drive and DCCD differential, it corners like it's on rails. The sight of rally blue paint with gold wheels always gets my adrenaline pumping, especially the manual transmission version - the exhaust pops during gear shifts are downright addictive. When buying used, watch out for engine condition as many have been thrashed. The new generation now comes with a 2.4T, but old-school enthusiasts still swear by the EJ207's red-top engine.

What is the Difference Between 6-Seater and 7-Seater Cars?

1. Number of Seats: The interior space of 6-seater and 7-seater cars is generally similar, with the main difference being the number of seats. A 6-seater car typically adopts a 2+2+2 seating layout, while a 7-seater car usually has a 2+3+2 layout. The 7-seater has one additional seat in the middle row compared to the 6-seater, but the rear seats are often more cramped. 2. Vehicle Inspection Frequency: According to the 'Regulations for the Implementation of the Road Traffic Safety Law', small passenger vehicles with 7 seats or more are required to undergo inspection every two years, while those with 6 seats or fewer are exempt from inspection for the first six years. 3. Insurance Premiums: Insurance companies classify small passenger vehicles based on the number of seats, such as those with up to 6 seats, 6-10 seats, and 11-20 seats. The premium varies depending on the number of seats, with higher seat counts generally leading to higher insurance costs.

Is intravenous carbon cleaning effective?

Intravenous carbon cleaning has certain effects, but it is not as effective as direct disassembly cleaning. The knowledge about carbon deposits is as follows: 1. Carbon deposits include two concepts: One concept is engine carbon deposits: During engine operation, a kind of coking substance produced by unsaturated olefins and gums in fuel under high temperature conditions. The second concept is carbon deposits in electrical discharge machining, which should be avoided as much as possible in EDM, especially in precision mold processing, as it can have fatal effects. 2. Carbon deposits are a manifestation of abnormal discharge machining in spark machines. From a general engine diagram, it can be clearly seen that the source of power → the air-fuel mixture must enter the combustion chamber through the intake valve; a small amount of gasoline will adhere to the intake valve, and under the high temperature of the engine, the hydrocarbons, paraffin, and gums in gasoline that cannot be completely burned will be turned into carbon deposits. If the fuel injector is fouled, the atomization state of the sprayed gasoline is poor, and the mixing of gasoline and air is uneven, which will increase the amount of gasoline condensed on the intake valve.

What is the correct way to charge a car battery?

Car battery charging involves the following steps: 1. Turn off the engine and remove the battery from the vehicle. 2. Adjust the battery's liquid level to the specified height using distilled water or a dedicated battery replenishment solution. 3. Connect the battery to be charged according to the rated voltage and current specified by the charging equipment. Remember that the total voltage of the battery must not exceed the rated voltage of the charging equipment. 4. Select the appropriate charging current based on the battery's capacity for constant current charging. 5. Plug in the charger, attach the red clamp to the battery's positive terminal marked with a plus sign, and the black clamp to the negative terminal marked with a minus sign. Turn on the switch to start charging, generally not exceeding 12 hours. 6. After charging, check if the density of the battery's electrolyte meets the requirements. If not, first pour out a small amount of the original electrolyte. If the density is too low, add a concentrated electrolyte with a higher relative density; if the density is too high, add distilled water to dilute until the liquid level meets the specified height.

Why was Camry renamed from Jiaming?

Camry was renamed from Jiaming because, after its domestic production in China, Guangzhou Toyota hoped that the new name would help establish a completely new image. Through this upgrade, the product could undergo a 'metamorphosis' in all aspects. Additionally, as a global model, CAMRY's name was transliterated to emphasize its global synchronization concept. Below is some expanded information about the Camry: 1. The new Camry has dimensions of 1455MM × 4900MM × 1840MM, and its trunk offers a large capacity, meeting the travel and cargo needs of average families. 2. In terms of power, the Camry provides three options: 2.0L, 2.5L, and 2.5L hybrid, paired with a CVT transmission. The 2.0L version delivers a maximum horsepower of 178 and a peak torque of 210 Nm. 3. The 2.5L hybrid version is equipped with advanced dual-engine technology, offering not only strong performance but also setting benchmarks in ultra-quiet operation and ultra-low fuel consumption among its peers.

How to Jump Start a Car?

Here is the correct method for connecting jumper cables to a car: 1. Ensure the battery of the vehicle providing the jump has sufficient charge. 2. Check the voltage of the dead car's battery to ensure it matches the voltage of the rescue vehicle's battery. 3. Position the two cars close enough for the cables to connect, and inspect both car batteries for any leaks, cracks, or damage. 4. Attach the red cable clamp to the positive terminal of the dead car's battery, and the other clamp to the positive terminal of the rescue car's battery. 5. Attach the black cable clamp to the negative terminal of the dead car's battery, and the other clamp to the negative terminal of the rescue car's battery. Additional information on jump-starting a car: 1. When connecting the negative cable to the dead car, try attaching it to a metal part of the engine. This improves the starter's current circuit contact, making it easier to start. 2. Ensure every connection point is securely fastened to avoid poor contact, which may prevent a successful start. 3. Avoid letting the positive and negative terminals of the battery touch each other, as this can create intense sparks and pose a danger.

Under what circumstances does an engine require a major overhaul?

An engine requires a major overhaul under the following circumstances: 1. When there is excessive clearance between the piston and cylinder wall causing blue smoke emission, a major overhaul is necessary. 2. Severe black smoke emission from the engine. If cylinder pressure measured with a compression gauge is below normal values, a major overhaul is required. 3. Abnormal noises during engine operation. When unusual sounds are detected, the engine must be disassembled for inspection or measured using an engine noise detector. 4. Knocking sounds from connecting rod bearings (big end and small end bearings), especially when the small end bearings are severely burnt and the crankshaft shows significant wear. 5. Scuffing sounds from cylinder walls. Upon disassembly, severe scoring is found between pistons and cylinder walls.
