Engine cylinder pressure is between 1100 and 1300kpa. The reasons for insufficient engine cylinder pressure are: Insufficient cylinder lubrication causing cylinder scoring, leading to excessive cylinder wall wear; Poor or damaged cylinder head gasket sealing, resulting in insufficient airtightness between the cylinder block and cylinder head; Excessive flatness of the two contact surfaces between the cylinder head and cylinder block, causing poor cylinder sealing; Intake and exhaust valves not closing tightly; Malfunction in the vehicle's cooling system leading to insufficient engine heat dissipation. The solutions for insufficient engine cylinder pressure are: Replace piston rings or cylinder liners; Replace the cylinder head gasket and tighten the screws to the specified torque; Check if the water passages are clear, pay attention to adding coolant, and promptly replace or eliminate any leaking components.

What is the difference between full-size tires and non-full-size tires?

Full-size tires and non-full-size tires differ in that full-size tires have the same specifications as the four original tires of the vehicle and use the same wheel rims as the original wheels. Non-full-size tires, on the other hand, are tires with narrower tread widths or smaller rim sizes, typically using steel rims and have speed limitations (maximum speed not exceeding 80 km/h). They can only serve as a temporary replacement for the original tires. Below is relevant information about tire replacement: 1. Tire replacement period: Some vehicles have been used for a long time but have not been driven frequently, resulting in low actual mileage, and their tires may not appear heavily worn. However, scientific experiments have shown that regardless of the brand, new tires will undergo changes in physical properties after being stored for three years due to factors like wear and oxidation. Indicators such as wear resistance and other strength metrics will significantly decline, and the potential risk factor will correspondingly increase. Therefore, major international tire companies set the aging period for tires at three years, and tires that have not been sold after three years will be downgraded or scrapped. 2. Purchasing car tires: Whether buying a new car, a used car, or specifically purchasing tires, it is essential to pay attention to the manufacturing date of the tires. This point can also serve as an additional skill to secretly assess the accurate age and condition of the vehicle.

Why can't the Honda Envix be used for Didi?

This is because the vehicle does not meet the entry model standards of the region, which vary by location. Below is relevant information about the Honda Envix: 1. Engine: The Honda Envix is a compact sedan under the Honda brand, equipped with two types of engines—a 1.5L naturally aspirated engine and a 1.0L turbocharged engine. The model with the 1.5L naturally aspirated engine is a hybrid version. 2. 1.5L Naturally Aspirated Engine: It delivers 109 horsepower and a maximum torque of 134 Nm, with a maximum power output at 6,000 rpm and peak torque at 5,000 rpm. This engine features i-VTEC technology and multi-point fuel injection, utilizing an aluminum alloy cylinder head and block. The electric motor paired with this engine has a maximum power of 96 kW and a maximum torque of 267 Nm. 3. Honda Envix's 1.0L Turbocharged Engine: It produces 122 horsepower and a maximum torque of 173 Nm, achieving peak power at 5,500 rpm and maximum torque between 2,000 and 4,500 rpm. This engine employs direct fuel injection and an aluminum alloy cylinder head and block. It is paired with either a 6-speed manual transmission or a CVT. The CVT is a relatively simple automatic transmission, consisting of two pulleys and a steel belt. The steel belt can move along the pulleys.

What Causes the Engine Exhaust System Warning Light to Illuminate?

Here are the reasons and solutions for the engine exhaust system warning light illuminating: 1. In most cases, the illumination of the engine exhaust system warning light is caused by damage to the oxygen sensor in the three-way catalytic system or poisoning of the three-way catalytic converter due to poor fuel quality in China. If this light comes on while driving, immediately reduce speed and proceed to the nearest repair service station for inspection. 2. If the vehicle cannot start after the warning light comes on, this is usually due to a malfunction in the fuel pump or ignition system. If the vehicle can still be driven but exhibits severe shaking, lack of acceleration power, or other symptoms, it is advisable to stop driving. This not only prevents further damage to the engine but also ensures personal safety.

What does the term 'travel lane' mean?

Travel lane refers to the ribbon-like portion of a highway designated for various vehicles to travel longitudinally in a safe and smooth manner. Below is relevant information about travel lanes: Composition of travel lanes: A travel lane consists of individual lanes, where each lane is designated for single-file vehicle movement. Travel lanes only include regular driving lanes and overtaking lanes, excluding other specially designated lanes such as steep slope lanes or speed change lanes. Width of travel lanes: Generally, the width of travel lanes on urban roads is 3.5 meters, while on expressways it's 3.75 meters. During daily driving, vehicles should maintain stable movement within a single lane as much as possible to avoid safety hazards caused by frequent lane changes.

What is a Wet System Composed of?

Wet system consists of wet alarm valve assembly, closed sprinkler heads, water flow indicators, control valves, end water test devices, piping, and water supply facilities. Working principle of wet system: When a fire occurs, the ambient temperature around the fire source continues to rise. When the ambient temperature reaches the activation temperature of the closed sprinkler head, the thermal element of the sprinkler head activates, causing the sprinkler to open and discharge water to extinguish the fire. As water flows through the pipeline, the water pressure on one side (system side) of the pipe network decreases, causing the wet alarm valve disc to open due to the pressure difference between the upper and lower sides, supplying water to the system for firefighting. The water flow indicator installed in the main pipe of the affected area activates due to water flow, converting the water flow signal into an electrical signal. Upon receiving the electrical signal from the water flow indicator, the alarm control panel emits audible and visual alarm signals, indicating the fire-affected area. Simultaneously, the wet alarm valve opens, allowing a portion of water to flow into the alarm pipeline. After a delay of 5-90 seconds through the retarder, the water flow impacts the hydraulic mechanism, causing the alarm bell to sound. The rising pressure at the alarm port activates the pressure switch, which directly sends an electrical signal to the fire pump control cabinet to start the fire pump for pressurizing and supplying water, while also transmitting the signal to the fire control center, achieving the purpose of continuous automatic sprinkler fire extinguishing.

Does the Engine Guard Plate Affect Engine Heat Dissipation?

Theoretically speaking, the engine guard plate may have an impact on the vehicle's heat dissipation, but in reality, the effect is minimal. Here is the relevant information: 1. The engine's heat dissipation performance is mainly reflected in the front grille, engine compartment design, water pipes, and radiator design, with only a small portion being dissipated through the chassis. Therefore, there is no need to worry about this aspect. 2. The engine guard plate is a protective device for the engine, equivalent to adding a protective layer to the car's chassis. Of course, the design of the engine guard plate may vary for different car models. When driving on low-lying roads or gravel roads, there is always a concern about stones or debris hitting the engine, which is why many people install guard plates for the purpose of protecting the engine.
