The differences between car displacement with T and without T are as follows: 1. A car with T refers to the use of a turbocharged engine; without T indicates that the car uses a naturally aspirated engine. 2. Compared to turbocharged engines, naturally aspirated engines make insufficient use of exhaust gases, resulting in lower engine efficiency. 3. For the same displacement, the power of a naturally aspirated engine is inferior to that of a turbocharged engine. 4. Turbocharged engines operate at higher temperatures, have lower reliability compared to naturally aspirated engines, and a shorter service life.

I've driven quite a few cars with and without turbochargers (T). The ones with T have smaller displacements but deliver greater power, offering explosive starts and strong acceleration with that exhilarating push-back feeling, though sometimes there's a slight delay in throttle response. They're fantastic for high-speed overtaking. Naturally aspirated engines (without T) provide smooth, linear power output, making driving relaxed and comfortable without any jerking, which is great for stop-and-go city traffic. In terms of maintenance, turbocharged engines are more prone to expensive turbo failures, with replacement parts costing thousands each time, while naturally aspirated engines are more durable and cost-effective. I think turbocharged engines are more fuel-efficient and eco-friendly, squeezing out big power from small displacements, which aligns with current trends. However, for long-term ownership, it's crucial to pick a high-quality turbo model to avoid headaches.

What causes the clicking sound when turning the steering wheel of the Nissan Qashqai?

The reasons for the clicking sound when turning the steering wheel of the Nissan Qashqai: 1. If the abnormal sound comes from below the steering wheel, it is caused by the steering column dust cover. Lack of lubrication can produce friction sounds. The owner only needs to apply some grease inside the dust cover, and the abnormal sound will disappear; 2. If the abnormal sound comes from inside the steering wheel, it is caused by the clock spring. Remove the steering wheel clock spring and apply some grease. If the sound persists, the clock spring needs to be replaced. The Nissan Qashqai is an SUV model from the Nissan Motor Group. In terms of body dimensions, its length, width, and height are 4401mm, 1837mm, and 1611mm respectively, with a wheelbase of 2646mm.

What does 'ETC display tag failure' mean?

ETC display tag failure is caused by users privately removing or relocating the OBU device, or by the loosening or detachment of the ETC electronic tag. Since ETC is dedicated to specific vehicles and has a protective interlock during installation, there is a push-button switch on the side tightly attached to the car's front windshield. If this switch button is triggered twice consecutively, it will cause the ETC electronic tag to fail. ETC is an electronic toll collection system, also known as an automatic road toll system. It uses dedicated short-range microwave communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at toll stations, combined with computer networking technology for backend settlement processing with banks. This achieves the purpose of vehicles paying tolls without stopping when passing through road and bridge toll stations.

Is It Normal for a Sedan's Chassis to Rust?

It is normal for a sedan's chassis to rust because the working environment of the car chassis is very harsh, often exposed to rainwater, which can lead to rust over time. The original chassis usually comes with a layer of anti-rust coating, but impacts during use or oxidation and peeling can cause the chassis to rust. If the car chassis is severely rusted, rust removal and anti-rust protection treatments are necessary. The car chassis consists of four parts: the transmission system, the running gear system, the steering system, and the braking system. Its function is to support and install the car engine and its various components and assemblies, forming the overall shape of the car, receiving the engine's power, enabling the car to move, and ensuring normal driving.

Can Antifreeze Be Diluted with Water?

Antifreeze can be diluted with water, but only distilled water should be used, and it should not be added in excessive amounts. Adding too much water can impair the radiator's functionality. Antifreeze is primarily an aqueous solution of ethylene glycol. Its main purpose is to prevent the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine block due to expansion. The full name is antifreeze coolant. Antifreeze is a specially formulated coolant additive designed for liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and inhibiting scale and corrosion year-round. A typical antifreeze formula consists of purified water, methanol, and other substances, including dyes, corrosion inhibitors, and descaling agents. It is recommended to use antifreeze as the engine's circulating fluid to ensure optimal heat dissipation, effective cold-weather protection, and overall engine performance.

What does ECO mean in automatic transmission?

ECO in automatic transmission refers to the car's economical driving mode. ECO is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator on the dashboard lights up, it indicates that the vehicle's economical mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type has a dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator lights up, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active Eco mode does not have a dedicated button. When the Eco indicator on the dashboard lights up, it serves merely as a reminder function. The Eco mode automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator. Most cars use the active Eco driving mode, which means they have a dedicated switch button. During daily driving, we can activate the Eco mode. However, it is unnecessary to activate the Eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not reflect the fuel-saving characteristics of Eco mode and could instead affect the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 km per hour, the car prioritizes speed, and the Eco mode automatically deactivates. During idle parking or in N/P gear or manual mode, the Eco mode may also become ineffective. When a high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function in this case.

What Causes the Accord's Low-Speed Jerking?

Here are the specific reasons for the Accord's low-speed jerking: 1. Engine oil passage blockage: The engine's ignition, air intake, and fuel injectors collectively determine fuel combustion, which is also the source of the engine's power. If the air intake volume decreases, the ignition weakens, or the fuel injection reduces, the power will be insufficient, leading to a jerking sensation. 2. Dirty transmission oil: This can cause damage to the solenoid valve. If sludge in the transmission oil circulates and blocks the oil passages in the valve body, jerking issues will arise. Over time, this can lead to a series of transmission problems such as overheating, impact, and slipping. 3. During the break-in period: It is normal for a car to experience slight jerking while driving, as the vehicle's power output and component engagement are not at their optimal levels. Additionally, the transmission's computer has a self-learning mechanism that continuously adjusts the oil pressure for gear shifting.
