What Causes the Engine Light to Illuminate and the Car to Shake?

The reasons for the engine light illuminating and the car shaking are: 1. Poor combustion of the air-fuel mixture in the engine. When the mixture in the cylinder is too rich, the vehicle may experience knocking and shaking. Conversely, when the mixture is too lean, the vehicle may exhibit symptoms of weak acceleration. 2. Malfunctions in the working conditions of spark plugs, high-voltage wires, and ignition coils, poor performance of the ignition system, or inadequate spark plug firing. 3. Abnormal fuel supply pressure or faults in the intake pressure sensor. Engine maintenance precautions: 1. Do not blindly remove the thermostat due to high engine temperature. Without the thermostat, the coolant can only circulate in a large loop, unable to regulate cooling intensity, making it difficult to maintain the engine at an optimal operating temperature. This can result in the engine frequently operating at lower temperatures, leading to reduced power, accelerated wear, and increased fuel consumption. 2. Drive within the normal temperature range specified in the car's user manual to ensure the engine's longevity.

Which way to steer when reversing into a narrow parking space?

When reversing into a narrow parking space, you can steer towards the wider side to make that side narrower and prevent the other side from crossing the line. If the left side is wider, steer left to move the car to the left. The key is to observe the left rearview mirror. If it shows a 'V' shape (wider at the front and narrower at the back), the left side is narrow, and you should steer right. If it shows a '^' shape (narrower at the front and wider at the back), the right side is narrow, and you should steer left. Steering tips: Before reversing, check the rear situation, plan the reversing path, and ensure the front won't hit obstacles. When making large steering adjustments, the front wheels have a larger turning radius than the rear wheels, causing the front to swing outward more. Be careful to avoid hitting obstacles with the front. This method is more suitable for parking on the right side or when longer reversing distances are needed. If the rear needs to move right, steer right; if left, steer left. This is the same as steering when driving forward. Don't focus only on the rear while reversing. After ensuring rear safety, frequently check the side mirrors for obstacles and adjust the steering to correct the car's position.

How many kilograms is 30 liters of gasoline equivalent to?

30 liters of gasoline equals 60 kilograms. The English name for gasoline is 'gasoline' or 'gas' (American English), also known as 'petrol' (British English). It is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through distillation or cracking processes, primarily used as fuel for spark-ignited internal combustion engines. It mainly consists of organic compounds obtained from crude oil distillation and various additives. Although gasoline yield varies with crude oil composition, typically, a barrel of 42 US gallons (160 liters) of crude oil can produce about 19 US gallons (72 liters) of gasoline after refinery processing. The octane rating of gasoline measures the anti-knock properties of a specific gasoline mixture (which can cause knocking and reduce the efficiency of reciprocating engines). Depending on the octane rating, gasoline is produced in several grades. Other chemicals are often added to gasoline to improve chemical stability and other performance characteristics, control corrosiveness, and maintain fuel system cleanliness. Common gasoline grades available in the market today are 92 and 95. Generally, the higher the gasoline grade, the higher the octane rating and the better the anti-knock performance. 92-grade gasoline contains 92% isooctane and 8% n-heptane, while 95-grade gasoline contains 95% isooctane and 5% n-heptane. To determine which gasoline is suitable for a car, besides checking the appropriate gasoline grade in the car's manual, you can also find it on the fuel tank cap, which usually indicates the recommended grade. Typically, the gasoline grade can also be decided based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92-grade gasoline, those between 10.0-11.5 should use 95-grade gasoline, and those with higher compression ratios should use 98-grade gasoline. However, with the use of some new technologies, the compression ratio alone cannot determine the appropriate gasoline grade. High compression ratio engines can be tuned to use lower-grade gasoline because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role.

What are the specific introductions of the Honda EX125?

The specific introductions of the Honda EX125 include the following three points: 1. Appearance: The overall design is simple and elegant, giving a sense of high quality, without the cheap feel of conventional practical small scooters. This advantage mainly comes from the stable and generous model design and relatively detailed craftsmanship of this scooter. 2. Power: The EX125 is equipped with Honda's NSC125 engine and PGM-FI fuel injection system. Such a combination can be considered a golden partnership in practical small scooters and also has high technical specifications. The benefit is that its power and fuel consumption performance are relatively ideal, placing it in the top tier among models of the same displacement. 3. Configuration: Compared to traditional practical small scooters, the EX125 is quite good. For example, it adopts practical configurations such as LED headlights and combined braking system. Of course, such performance is still different from being absolutely rich in configurations. It can only be said that it has not fallen behind among models of the same level and basically meets the price performance.

Does the Excelle have a one-key start feature?

The one-key start feature in the Excelle is only available in certain models. Taking the 2016 model as an example, only the Luxury Edition and the Sport Flagship Edition are equipped with the one-key start function. For the 2017 model, only the Luxury Edition has this configuration. The one-key start device is part of a smart car system, serving as a button mechanism that simplifies the starting process and can also be used to turn off the engine. This device can be retrofitted either at the original car key lock position or as an independent panel. Taking the Excelle 2021 Modified 1.3T Automatic Light Hybrid Base Model as an example, its dimensions are 4609mm in length, 1798mm in width, and 1486mm in height, with a wheelbase of 2640mm. The body structure is a 4-seat, 5-door sedan. In terms of power, the Excelle 2021 Modified 1.3T Automatic Light Hybrid Base Model is equipped with a 1.3L inline 3-cylinder turbocharged engine, delivering a maximum power of 120kW and a maximum torque of 230Nm, paired with a 6-speed automatic transmission.

Which One is Reverse Gear in an Automatic Transmission?

In an automatic transmission, the reverse gear is indicated by the letter 'R'. Here are some precautions for reversing: 1. When reversing, press the brake to stop the car completely, then press the lock switch on the gear lever to shift into 'R' gear; 2. Check the side mirrors and rearview camera to ensure there are no obstacles behind the car, and also honk twice to alert pedestrians and vehicles nearby; 3. Slowly release the brake to allow the car to move at a low speed. The gears in an automatic transmission car include: 1. 'P' for Parking, used when the vehicle is parked for an extended period; 2. 'N' for Neutral, used when the vehicle is parked briefly without turning off the engine; 3. 'D' for Drive, where the vehicle automatically shifts gears based on throttle input and speed when the gear lever is in 'D'; 4. 'S' for Sport mode, which makes the vehicle more sporty to drive; 5. 'M' for Manual mode, where gear shifts are done manually by the driver when the gear lever is in 'M'; 6. 'L' for Low gear.
