What should be paid attention to in Subject 2?

Precautions for Subject 2 exam: 1. Before the exam: Dress comfortably and be mentally prepared; pay attention to key points when reversing into the garage, do not turn left or right; when parallel parking, ensure the rear wheel exceeds the edge line of the garage, adjust the distance properly, remember to turn on the turn signal and honk the horn. 2. During the exam: When making a sharp turn, steer the wheel decisively after aiming at the right position; when driving on a curve, make wide turns after entering the curve, maintain a steady speed, and avoid crossing the line in all the above situations. 3. After the exam: Drive the car back to the starting position after the exam, sign for confirmation before turning off the engine. 4. Mock exam: The purpose of the mock exam is to familiarize candidates with the exam environment and allow the instructor to point out areas prone to deductions, so the mock exam is absolutely essential. Being well-prepared is the best way to face the challenge.

What does truck gear ratio mean?

Gear ratio refers to the transmission ratio of the internal transmission gears in a vehicle. There are many gears in a truck's transmission, and the transmission ratios between these gears vary. Vehicles also have main reduction gears, and different vehicle models have different main reduction gear ratios. Related information: When starting a car normally, first gear is required. First gear has a relatively large transmission ratio, resulting in greater torque, which allows the vehicle to start smoothly. However, the speed in first gear is not very high, and most vehicles can only reach a maximum speed of 20 kilometers per hour in first gear. If a small gear drives a large gear to rotate, the transmission ratio is relatively large, resulting in greater output torque. If a large gear drives a small gear to rotate, the transmission ratio is relatively small, resulting in higher output speed. Function of reduction gears: The main reduction gear in the vehicle differential serves to reduce speed and increase torque. When the engine operates normally, the speed is very high, so the transmission and main reduction gear are needed to reduce the speed, thereby increasing torque and allowing the vehicle to drive normally. Truck gear ratio: The gear ratio of a truck generally refers to the ratio of the main reduction gear. This ratio is fixed, and changing it requires replacing the main reduction gear.

What is the e3 car?

e3 is the third-generation evolution of Mitsubishi's EVO. It is also the first prototype of Toyota's classic sports car, the Corolla. FC is the nickname for Mazda's twin-rotor engine sports car, also known as the "Twin Star" RX-7. Here is an introduction to the e3: 1. Exterior: All aerodynamic components, including the front bumper, front lip, side skirts, rear bumper, and rear spoiler, have been completely renewed. In other words, to meet the challenges of higher speeds, the goal was to increase downforce and significantly improve aerodynamics. Additional air intakes were added on both sides of the front lip to enhance the cooling of the braking system. The rear spoiler was widened to match the width of the car body, ensuring better downforce. 2. Configuration: To meet the demands of WRC challenges, more powerful performance was essential. Therefore, the first improvement was the pistons, increasing the compression ratio from 8.5 to 9.0, and the turbocharger was redesigned to enhance power output at high RPMs. Additionally, the exhaust system's pipe diameter was enlarged to reduce backpressure, increasing horsepower by 10 to reach 270 HP. With a 2.0L displacement, it delivers 270 HP.

What does MIVEC engine mean?

MIVEC engine is a variable valve timing system engine produced by Mitsubishi, where MIVEC stands for Mitsubishi Innovative Valve timing Electronic Control system. Relevant information is as follows: 1. Function: The MIVEC system primarily achieves low fuel consumption and low emissions at certain engine speeds. This system has brought new development to Mitsubishi vehicles. Engines equipped with the MIVEC system, like conventional engines, adopt a four-valve-per-cylinder design with two intake and two exhaust valves. However, the difference lies in its ability to control the opening and closing size of the two intake valves per cylinder. 2. Advantage: In traffic congestion scenarios, engines equipped with the MIVEC system can save more fuel compared to conventional engines.

What to Do If You Miss an Exit on the Highway?

Drive to the next exit or use the underground passage in the service area. On highways, it is never allowed to stop, reverse, or drive in the wrong direction at any time. Here are the solutions for missing an exit while driving on the highway: 1. Drive to the next exit: On highways, it is never allowed to stop, reverse, or drive in the wrong direction at any time, as doing so can easily cause traffic accidents! The best approach is to follow the principle of 'making the best of a mistake'—exit at the next available exit, then make a U-turn and take a longer route. Although it means driving a bit farther, you can still get back on track. 'Better to take ten steps safely than one step dangerously'—it may take a little more time, but it ensures a safe journey. 2. Use the underground passage in the service area: Some highway service areas have underground passages for goods delivery. If you realize you've missed an exit, you can ask the service area staff if you can use this passage to make a U-turn. However, since this passage is not for public use, many service areas do not allow private vehicles to pass through.

What is the load capacity of a front four rear eight dump truck?

The load capacity of a front four rear eight dump truck is approximately 38 tons. According to national regulations, trucks cannot exceed 30% overload, so the maximum load capacity of a front four rear eight dump truck is 49.4 tons. Depending on the model, there may be some variation in load capacity. More details are as follows: 1. Front four rear eight: Refers to a vehicle with two axles and four wheels for the front steering wheels and two axles and eight wheels for the rear drive wheels. Generally, front four rear eight configurations are commonly used in heavy-duty trucks or dump trucks. Among them, two-axle trucks typically have a load capacity of around 20 tons, three-axle trucks around 30 tons, four-axle trucks around 40 tons, and five-axle trucks around 50 tons. When loading goods, it is important to follow the vehicle's specifications and relevant requirements from the public security department to avoid overloading violations. 2. Precautions for driving heavy-duty trucks: 1) Be mindful of blind spots: Pay attention to blind spots when reversing or turning to prevent safety accidents. 2) Long-distance trips: Before long-distance trips, check tires, brakes, lights, etc., to ensure there are no safety hazards. 3) Check water in the radiator: Before starting the truck, check if there is enough water in the radiator to prevent engine overheating, which could affect its lifespan. 4) Follow loading regulations: Also, be aware of restricted routes in different areas to avoid violations.
