What causes severe carbon buildup in the Corolla Hybrid?

Black carbon deposits in the exhaust pipe of the Corolla Hybrid refer to the adhesive substances formed when fuel and lubricating oil that enters the combustion chamber fail to burn completely. The main components are hydroxy acids, asphaltenes, and tar substances, which adhere to the intake/exhaust valves, cylinder edges, piston tops, spark plugs, and combustion chambers. Under the repeated high-temperature conditions of the engine, these substances gradually accumulate and form hard, coked carbon deposits, known as carbon buildup. Below is more information about the 2021 Corolla: 1. Body dimensions: The 2021 Corolla measures 4635mm in length, 1780mm in width, and 1435mm in height, with a wheelbase of 2700mm and a fuel tank capacity of 50 liters. 2. Suspension: The front suspension uses a MacPherson strut independent suspension, while the rear suspension employs an E-type multi-link independent suspension.

Does Engine Idling Damage the Car?

Engine idling does damage the car. Here are the specific details: 1. Idling for twenty minutes can cause certain harm to the car: The main damage is that prolonged or frequent idling can easily lead to carbon buildup inside the engine cylinders and affect the throttle. When carbon deposits accumulate to a certain extent, they can reduce the car's power performance and, over time, easily cause engine wear. 2. The vehicle does not perform external work while idling: In idle state, the engine only overcomes its own resistance, so the engine should be turned off during prolonged waiting. Here are some additional details: 1. Introduction: Idling is a working condition of the car, referring to the engine running in neutral gear. 2. Repair and adjustment: When the engine is running, if the accelerator pedal is completely released, the engine is in idle state.

What engines are used in the Countryman?

The Countryman is equipped with two engines: one is a 1.5-liter turbocharged engine, and the other is a 2.0-liter turbocharged engine. Detailed specifications of the two engines are as follows: 1. The 1.5-liter turbocharged engine delivers 136 horsepower, with a maximum torque of 220 Nm. The maximum power output is achieved between 4,400 and 6,000 rpm, while the maximum torque is available from 1,400 to 4,300 rpm. This engine features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block. It is paired with a 6-speed automatic transmission. 2. The 2.0-liter turbocharged engine produces 192 horsepower, with a maximum torque of 280 Nm. The maximum power output is achieved between 5,000 and 6,000 rpm, while the maximum torque is available from 1,350 to 4,600 rpm. This engine also features direct fuel injection technology and uses an aluminum alloy cylinder head and block. It is paired with an 8-speed automatic transmission.

Should You Press the Clutch When Decelerating in Driving Test Phase 3?

Decelerating with the clutch depends on the vehicle speed. If the car is in 3rd gear or higher and moving at a relatively high speed, the student driver does not need to press the clutch. Instead, they can use the "pump braking" method—lightly pressing and releasing the brake pedal repeatedly. However, if the speed has significantly decreased to 2nd or 1st gear and the engine starts to struggle, pressing the brake without the clutch may stall the engine. In such cases, both the brake and clutch should be pressed simultaneously. The correct method for decelerating in Phase 3 is as follows: 1. On flat roads with light traffic, when the speed is above 30km/h and only brief braking is needed, gently tap the brake pedal without pressing the clutch. 2. When passing bus stops, school zones, waiting at traffic lights, in traffic jams, or coming to a complete stop, shift to a lower gear and press both the clutch and brake pedals.

What Causes Severe Engine Shaking During Cold Start?

Reasons for severe engine shaking during cold start: 1. Excessive carbon deposits. Severe carbon buildup in the engine cylinders can lead to spark plug blockage and valve clogging, directly causing vehicle shaking during idling. If the car's acceleration performance has significantly deteriorated and the shaking persists, consider performing an engine cylinder cleaning. 2. Fuel supply system malfunction. Unstable fuel pressure can cause inconsistent air-fuel mixture concentration, resulting not only in shaking but also unstable idling. First consider replacing the fuel filter, as prolonged use may cause filter clogging. Then check the fuel pressure bypassing the fuel filter - if abnormal, it may indicate a fuel pump issue. 3. Worn engine mounts. If the engine shaking progressively worsens without corresponding power loss, consider whether it's an engine mount problem. 4. Misfiring cylinders. This is the most common cause of engine shaking, typically caused by issues with ignition coils or spark plugs. If ignition coils malfunction or spark plugs fail to fire properly, the vehicle will experience shaking.

Where to Check the Production Date of a Newly Purchased Car?

New car production dates can be checked in two places: the co-pilot side and the certificate of conformity. Details are as follows: 1. Below the B-pillar on the co-pilot side, open the door to see it. This nameplate only specifies the year and month, and the vehicle's chassis number is noted on the nameplate. 2. The certificate of conformity that comes with the new car, located in the upper right corner of the certificate. The production date marked here can be specified to the year, month, and day. Note: This is not applicable to all models. When the new car arrives at the dealership from the factory. There will be a factory paper nameplate on the front windshield of the driver's seat. The paper nameplate indicates the chassis number and the MIIT fuel consumption. If the bottom of the paper nameplate specifies the year, month, and day, then the production date on this nameplate can be used as a reference date. If the nameplate only specifies the year and month, then it cannot be used as the factory date.
