Is the Dongfanghong MF554 a large bridge or a medium bridge?

Dongfanghong MF554 is a large bridge. Appearance: Dimensions: 3910×1745×1720 (Length × Width × Height, height to steering gear). Front track: 1250 (mm), rear track: 1400～1600 (mm), minimum ground clearance: 350 (mm), minimum operating weight: 2296 (kg). Configuration: This machine is equipped with a direct-injection energy-saving diesel engine, featuring low fuel consumption, high torque reserve, excellent power economy, and emissions meeting the National II standard. It adopts an 8+8 meshing sleeve shuttle shift, reinforced chassis, and reasonable gear distribution. The final drive uses a planetary gear reduction mechanism, which is compact in structure, has a large transmission ratio, even load distribution, and long service life.

What does i-vtec mean?

i-vtec is a variable valve timing and lift control technology. Functions of i-vtec: It uses a method similar to VANOS and VVT-i to continuously rotate the camshaft for opening and closing, thereby achieving control of the valve overlap angle. This means the timing and overlap duration of the intake and exhaust valves are variable and controlled by oil pressure through the VTC system. Working principle of i-vtec: When the engine shifts from low to high speed, the electronic control unit automatically directs oil pressure to a small turbine inside the intake camshaft drive gear. Under this pressure, the turbine rotates relative to the gear housing by a certain angle, causing the camshaft to rotate forward or backward within a 60-degree range. This adjusts the intake valve opening timing, enabling continuous valve timing control.

Is EXH Intake or Exhaust?

EXH stands for exhaust. Exhaust: The full form of 'e' is exit, which means exhaust, while intake is represented by 'i', which stands for 'in'. The cylinder head, made of cast iron or aluminum alloy, serves as the mounting base for the valve mechanism and also acts as the sealing cover for the cylinder. Cylinder Head Damage: Common issues include warping deformation of the sealing surface between the cylinder head and cylinder bore (compromising the seal), cracks in the intake and exhaust valve seat holes, and damage to the spark plug installation threads. Particularly for cylinder heads cast from aluminum alloy, due to their lower material hardness and relatively weaker strength, they are more prone to deformation and damage, leading to a higher consumption rate compared to those made of cast iron.

How to Remove Bad Odors Inside a Car?

Here are some quick methods to eliminate bad odors inside a car: 1. Use fresh-smelling car fragrances: Place car fragrances such as perfumes or air fresheners inside the vehicle. These are popular products many car owners purchase. The automotive accessories market offers various brands and types of car fragrances, but some are of poor quality. Using low-quality fragrances can backfire, as their scents may mix with the existing odors, either worsening the smell or causing symptoms like dizziness and nausea. When selecting car fragrances, besides paying attention to product quality, opt for those with a fresh scent. 2. Use fruits to remove car odors: Certain fruits, such as lemons, oranges, and pineapples, can help eliminate bad odors. The natural fragrance of these fruits will gradually spread throughout the car, masking the unpleasant smells.

Where is the most accurate place to connect the motorcycle tachometer signal wire?

Motorcycle tachometer signal wire connects the speed sensor to the instrument panel. Tachometer: It is one of the essential instruments in the mechanical industry, used to measure the speed, linear velocity, or frequency of motors. Commonly applied in manufacturing sectors such as motors, fans, papermaking, plastics, chemical fibers, washing machines, automobiles, aircraft, ships, etc. Working principle: The tachometer processes the received digital pulse signals (emitted by the sensor) and directly inputs them into the CPU's counting port. The software calculates the speed and the corresponding position of the pointer, then through the CPU's control port, amplifies and drives the stepper motor to rotate in both positive and negative directions, indicating the corresponding speed value (the pointer is directly mounted on the rotating shaft of the stepper motor). Each step of the stepper motor is only 1/3 degree.

What is the passing score for C1 License Subject 2?

The passing score for the C1 license Subject 2 exam is 80 points. The C1 Subject 2 exam mainly consists of five items: reversing into a garage, parallel parking, curve driving, right-angle turning, and hill start and stop. For automatic transmission (C2) Subject 2, the hill start and stop is not included. A C1 driver's license allows driving small and micro passenger vehicles, among others. C1 license exams consist of four subjects, with the other subjects as follows: Subject 1: Mainly tests basic knowledge of road traffic rules. Subject 3: Tests 16 driving skills including vehicle preparation, starting, straight-line driving, etc. Subject 4: Tests safe and civilized driving operation requirements, similar to Subject 1, it is a theoretical exam. Subject 2 Exam Tips: Before starting the car during the Subject 2 exam, adjust the seat height and rearview mirrors to ensure a wide field of vision, and fasten the seat belt. During the exam, do not stop unless the system indicates a failure. For parallel parking, find the correct angle, turn the steering wheel quickly, and react promptly to match the car's speed. For hill start and stop, remember to pull the handbrake, turn on the left turn signal when starting, release the handbrake, and stabilize the clutch. Press the accelerator while releasing the clutch to avoid stalling or rolling back. For right-angle turning, find the reference point before turning and coordinate with the car's speed. For curve driving (S-curve), slow down. For reversing into a garage, control the speed, find the reference point, and make minor adjustments if the rearview mirror shows any deviation. Subject 2 Deduction Items: Reversing into a garage: Vehicle body crossing the line—100 points deducted, failing the exam; failing to reverse into the garage—100 points deducted, failing the exam; stopping midway—5 points deducted each time; failing to complete the exam within the specified time—100 points deducted, failing the exam. Parallel parking: Vehicle body crossing the line after stopping—100 points deducted, failing the exam; stopping midway—5 points deducted each time; tires or body touching the curb—10 points deducted; failing to complete the exam within the specified time—100 points deducted, failing the exam. Curve driving: Wheels touching the road edge line—failing the exam; stopping midway—failing the exam; not using second gear or above—5 points deducted. Right-angle turning: Wheels touching the road edge line—failing the exam; stopping midway—5 points deducted each time. Hill start and stop: Front bumper or motorcycle front axle not aligned with the pole line and exceeding 50 cm—failing the exam; exceeding the specified start time—failing the exam; front bumper or motorcycle front axle not aligned with the pole line but not exceeding 50 cm—10 points deducted; vehicle body exceeding 30 cm but not 50 cm from the road edge line—10 points deducted; not pulling the handbrake tightly after stopping—10 points deducted. C1 License Exam Passing Standards: Traffic laws and related knowledge—90 points to pass. Field driving—80 points to pass. Road driving—80 points to pass. Safe and civilized driving knowledge—90 points to pass.
