What is the matching range between gears and vehicle speed?

1st gear is used for normal starting or climbing very steep slopes, with a speed generally around 10 km/h; 2nd gear is a transitional gear for acceleration after starting or for low-speed driving, with a speed generally around 20 km/h; 3rd gear is used at speeds between 20-40 km/h, commonly used for urban driving; 4th gear is used at speeds between 40-60 km/h; 5th gear can be used at speeds of 60 km/h or above. When driving a manual transmission, the gear shifting sequence must be from 1st to 2nd to 3rd to 4th to 5th gear, and skipping gears is not recommended. The downshifting sequence should be determined based on the condition of your vehicle, generally downshifting when the engine speed drops below around 1500 RPM. The larger the gear, the slower the rotation speed, corresponding to a lower gear and slower vehicle speed; the smaller the gear, the faster the rotation speed, corresponding to a higher gear and faster vehicle speed. If the gear does not match the engine speed, a mismatch between engine power and transmission gears will occur, leading to the phenomenon of the vehicle jerking forward and backward.

As an ordinary driver who frequently drives, I believe the matching range between gears and speed is about ensuring the engine and transmission work harmoniously to avoid that annoying shaking sensation. Generally, speeds of 0-15 km/h are suitable for 1st gear, like when starting off; 15-30 km/h for 2nd gear, allowing the car to transition smoothly; 30-50 km/h for 3rd gear, ideal for city driving; 50-70 km/h for 4th gear, perfect for ring roads; and speeds above 70 km/h should shift to 5th gear or higher. If the speed is too low for a high gear, the engine will struggle and consume more fuel; if the speed is high in a low gear, the RPM will soar, sounding unpleasant and harming the car. I usually rely on the speedometer and engine sound to determine the shifting point: if it's too noisy, shift up; if it's too sluggish, shift down. When driving a new car, don’t rush to go fast—take time to test different road conditions, like maintaining a low gear uphill to pull the RPM. Over time, this matching becomes instinctive, making driving comfortable while saving fuel and money.

What to Add When the New Car's Windshield Washer Fluid Runs Out?

When the new car's windshield washer fluid runs out, it is necessary to add new windshield washer fluid. Method for adding windshield washer fluid: Open the engine hood, and you can find the inlet for adding windshield washer fluid. The inlet for adding windshield washer fluid has a corresponding label. Once you find this label, you can add windshield washer fluid to the inlet. After filling up the washer fluid, remember to securely close the cap, retract the support rod, and close the front hood. Windshield Washer Fluid: It is a super-concentrated automotive glass cleaner. It features properties such as non-stickiness, anti-static, anti-corrosion, dustproof, cold-resistant, acid rain-resistant, and UV-resistant. For rubber and plastic materials, it helps maintain gloss and lubrication, preventing hardening and cracking.

What Causes Abnormal Engine Noise at 2000 RPM?

Engine noise at 2000 RPM can be attributed to the following reasons: External environmental factors: Weather conditions can play a role. If the car is operating in winter when temperatures are generally lower, and the engine remains at high speeds while cold, increased engine noise is normal. This phenomenon typically disappears once the engine warms up. Engine oil issues: Engine oil serves multiple purposes, including lubrication and cleaning of internal components. If the oil is low or deteriorated, it may fail to provide adequate lubrication, leading to increased wear during engine operation and consequently louder noise. Excessive engine carbon buildup: Carbon buildup is a chronic issue for engines. As the engine is used, carbon deposits accumulate over time. If not cleaned promptly, excessive buildup can cause various operational problems, such as reduced power output, one of which is increased engine noise.

Can You Add Purified Water If the Coolant Is Insufficient in Summer?

In summer, you can add purified water if the coolant is insufficient. Main Components: The primary components of antifreeze are ethylene glycol and water. The water here refers to purified or distilled water, not mineral water, as mineral water contains minerals that, compared to purified or distilled water, have impurities that cannot evaporate. Precautions: If the antifreeze is insufficient, you can add purified or distilled water, but never add mineral water. Not only will it increase the freezing point of the antifreeze, but the minerals in the mineral water can also react chemically with the components of the antifreeze, affecting its functionality. Antifreeze prevents the coolant from freezing in cold winter conditions when the vehicle is parked, thus avoiding the risk of cracking the radiator or damaging the engine block. Its full name is antifreeze coolant.

How many fire extinguishers are required for hazardous material vehicles?

Hazardous material vehicles are required to be equipped with two fire extinguishers. Types of hazardous material vehicles: Tank-type specialized transport vehicles: Generally used for transporting liquid hazardous chemicals such as flammable, explosive, and toxic substances; Box-type specialized transport vehicles: Typically employed for transporting solid hazardous chemicals like industrial explosives, detonators, and fireworks; Ordinary trucks: Their cargo compartments lack flame-retardant material layers or partitions on inner and outer surfaces, have poor airtightness, and lack functions such as high-temperature resistance, dustproofing, rainproofing, static electricity prevention, and lightning protection. Collisions can easily lead to large-scale leaks, fires, or explosions of hazardous chemicals. Reasons why hazardous material vehicles require fire extinguishers: There are mandatory regulations for public transportation vehicles such as passenger buses, taxis, and hazardous material vehicles where passengers are concentrated or fires are prone to occur, requiring drivers and relevant personnel to carry fire extinguishers onboard.

Is It Normal for the Wheel Hub Center Shaft of a New Car to Rust?

It is not normal for the wheel hub center shaft of a new car to rust. Reasons for the wheel hub center shaft rusting: From a chemical perspective, the principle of rusting is that iron reacts with oxygen and water to form iron oxide (Fe3O4) and various other oxides. During normal driving, the inner shaft of the tire is inevitably exposed to moisture, which naturally leads to rust. Methods to deal with wheel hub center shaft rust: If the rust is relatively mild, you can use high-grit sandpaper to polish the rusted area until it is clean. The most effective method is to use a rust remover. First, thoroughly clean the wheel, then spray an appropriate amount of rust remover on the rusted area. Next, scrub the area with a brush. Once the rust is removed, rinse the area with clean water.

Where is the boom holding valve of Komatsu 120 located?

The boom holding valve is installed between the boom control valve and the bottom of the boom cylinder. When the boom control lever returns to the neutral position, the boom holding valve prevents the boom from naturally descending, allowing the boom to remain in place. For Komatsu parts, you can contact Zhizao Dagan. Installation location: The boom holding valve is installed at the oil port from the main control valve to the bottom of the boom cylinder. When the boom control lever is in the neutral position, this valve prevents the oil at the bottom of the boom cylinder from returning to the tank through the boom main valve core under the influence of gravity, thereby preventing the boom from naturally descending. Precautions: Generally, only the boom and the arm have holding valves. Therefore, if the boom or arm drops, it is necessary to separately inspect the valve core and spring of the holding valve for wear or other foreign objects causing sticking issues. If the problem persists after cleaning, it can be resolved by replacement.
