How to Check the Coolant Level?

When the engine is cold, the fluid level should be between the upper and lower limits for normal operation. The functions of coolant include the following four points: 1. Winter antifreeze: Prevents the coolant from freezing and causing the radiator and engine block to crack. The freezing point of the coolant should be approximately 10°C lower than the lowest temperature in the region to prepare for sudden weather changes. 2. Anti-corrosion: The cooling system contains components such as the radiator, water pump, engine block and cylinder head, and water distribution pipes. Due to the different electrode potentials of various metals, electrochemical corrosion can easily occur under the influence of electrolytes. Additionally, acidic byproducts formed from the decomposition of glycol-based substances in the coolant and acidic exhaust gases from fuel combustion may infiltrate the cooling system, accelerating corrosion. 3. Anti-scaling: The coolant reduces scale formation during circulation to prevent clogging of the pipes and impairing the cooling system's heat dissipation function. Care should be taken when selecting and adding coolant. 4. Anti-boiling: Coolant that meets national standards has a boiling point exceeding 105°C, compared to water's boiling point of 100°C. This allows the coolant to withstand higher temperatures without boiling, meeting the cooling needs of high-load engines to a certain extent.

Can Temporary License Plates Be Used Across Provinces?

Cross-administrative jurisdiction temporary license plates can be used across provinces, while administrative jurisdiction temporary plates cannot. Below are the usage instructions for temporary license plates: Administrative Jurisdiction Temporary Plates: Administrative jurisdiction temporary plates (sky blue background with black characters and black borders), commonly referred to as urban temporary plates, allow vehicles to drive only within the jurisdiction and prohibit cross-province travel. The validity period for these plates is 15 days; Cross-Administrative Jurisdiction Temporary Plates: Cross-administrative jurisdiction temporary plates (brown-yellow background with black characters and black borders), commonly referred to as national temporary plates, permit vehicles to travel across provinces. The validity period for these plates is 30 days.

What is the name of the front hood of a car?

Automotive front hood is called the engine hood. Here is the relevant information about the engine hood: Function of the hood: The engine hood (also known as the engine cover) is the most prominent body component and one of the parts frequently inspected by car buyers. The main requirements for the engine hood are heat insulation, sound insulation, lightweight, and high rigidity. Its structure is in skeleton form, consisting of an outer panel and an inner panel. Function of the hood: The engine hood is generally composed of an outer panel and an inner panel, with heat insulation material sandwiched in between. The inner panel serves to enhance rigidity, and its geometric shape is selected by the manufacturer, basically in skeleton form.

How Many Cylinders Does the Honda Fit Have?

Honda Fit is a four-cylinder car. The introduction of Honda Fit and the working principle of the four-cylinder engine are as follows: Introduction: It is equipped with a 1.5-liter naturally aspirated four-cylinder Earth Dreams engine, with a wheelbase of 2530 mm, and the length, width, and height are 4109 mm, 1694 mm, and 1537 mm respectively. The maximum power is 96 kW, and the maximum torque is 155 Nm. The maximum power speed of this engine is 6600 rpm, and the maximum torque speed is 4600 rpm. Working Principle: When the combustion gas in the sealed cylinder expands, it pushes the piston to do work, converting the thermal energy of gasoline (diesel) into mechanical energy. It mainly consists of components such as the cylinder block, crankcase, cylinder head, and cylinder gasket.

What is the working principle of the Atkinson cycle?

The Atkinson cycle is based on the Otto cycle internal combustion engine. By using a set of complex linkage mechanisms, Atkinson made the compression stroke of the engine smaller than the expansion stroke. This ingenious design not only improves the engine's intake efficiency but also ensures that the expansion ratio is higher than the compression ratio, effectively enhancing the engine's efficiency. This working principle is known as the Atkinson cycle. The Atkinson cycle engine primarily features the following three technical characteristics: By increasing the compression ratio to 12 and relatively reducing the combustion chamber volume, the engine achieves higher thermal efficiency. Through a completely redesigned valve timing, the engine's expansion ratio is increased without a significant rise in the compression ratio, thereby avoiding the occurrence of knocking. By optimizing the matching of the electronic fuel injection system and adjusting the fuel injection quantity and ignition timing, the engine's thermal efficiency is further improved, and the fuel consumption rate is enhanced.

What brand is the transmission of the Trumpchi GS3?

The manufacturer of the Trumpchi GS3 transmission is Aisin. Established in 1969, Aisin is a world-renowned professional developer and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the highest market share globally. The Trumpchi GS3 transmission uses a 6-speed automatic manual transmission or a 6-speed manual transmission. The automatic manual transmission has eight forward gears. Essentially, an automatic manual transmission is a traditional AT or CVT transmission with added manual shifting functionality. The purpose of the automatic manual transmission is to enhance the driving pleasure of automatic transmission vehicles. When using the Trumpchi GS3 transmission in daily driving, the following points should be noted: Do not delay changing the transmission oil for extended periods. Prolonged failure to change the transmission oil can damage internal components such as bearings and the housing. Avoid coasting in neutral for long periods. While driving manual transmission models, many experienced drivers may coast in neutral, but for automatic transmission models, this can cause the transmission to overheat and produce a noticeable jolt when shifting back into D gear. Never shift into D/R gear before the vehicle has come to a complete stop. Many drivers, aiming for smooth operation, shift into reverse while the vehicle is still moving, which can severely damage the transmission gears and lead to gear grinding over time. Avoid frequently climbing steep slopes in D gear. On steep inclines, automatic transmission vehicles may overheat due to high load or shift prematurely, resulting in insufficient power. In such cases, use manual mode to limit low gears or switch to sport mode to protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, use a flatbed tow truck to move the vehicle onto the tow platform while it is in N gear. Avoid using tow ropes or towing the vehicle directly.
