What engine does the Envix use?

The Envix is equipped with two types of engines, model numbers P10A5 and LEB42. The P10A5 engine has a maximum horsepower of 122 HP, a maximum power output of 90 kW, a maximum power speed of 5500 rpm, and a peak torque of 173 N·m. The LEB42 engine has a maximum horsepower of 109 HP, a maximum power output of 80 kW, and a maximum power speed of 6000 rpm. Low consumption and high energy efficiency are the biggest highlights of this model. The Envix engine is equipped with a special engine featuring VETC technology, independently produced by Dongfeng Honda. For daily maintenance of the Envix engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD-SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions. For diesel engines, CB-CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What engine is used in the new Oushang X7?

The engine of the new Oushang X7 is independently produced by Changan Company, with its production site in Chongqing, making it a domestically manufactured engine. The engine model specification for the new Oushang X7 is JL476ZQCF, with a maximum power of 131kW (5500rpm), maximum horsepower of 178Ps, and maximum torque of 265N. For the daily maintenance of the new Oushang X7's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid faults, oil should be changed regularly based on usage conditions, and the oil level should be moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. When the amount is small, it suspends in the oil; when large, it precipitates from the oil, blocking the filter and oil holes, causing lubrication difficulties and wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.

Why can't the LNG pressurization valve increase pressure?

When the vehicle is loaded and the cylinder pressure is below 0.8 MPa, insufficient power may occur. You can open the pressurization valve and then the return valve to activate the cylinder pressurizer. Wait until the pressure increases to the range of 0.8~1.2 MPa before closing both valves. Below are relevant details: Precautions: If the cylinder pressure is too low, gas supply will be insufficient; if it is too high, it may trigger the safety valve to release gas, causing losses. The cylinder pressure should not exceed 1.7 MPa. LNG vehicle cylinders are designed with two-stage safety valves to account for pressure increases due to rising temperatures. When the internal pressure exceeds 1.2 times the normal working pressure, the primary safety valve activates to release gas, thereby reducing the pressure until it falls below 1.2 times the working pressure. If the pressure does not return to normal after the primary safety valve releases gas, the secondary safety valve will activate (at 1.8 times the working pressure). Maintenance: Do not place the cylinder in environments above 60°C for extended periods. Owners who install cylinders on the vehicle body with metal protective boxes should especially avoid exposing the vehicle to direct sunlight in summer. Avoid using the cylinder in high-static environments, prevent impacts, and keep it away from chemicals. Vehicle cylinders should be maintained at the contracted modification facility and inspected regularly to ensure the safety of users and others.

Can a downgraded driver's license be restored?

It is possible to restore a downgraded motor vehicle driver's license. If the driver's license was downgraded due to traffic violations or illegal activities, and the driver wishes to restore the original permitted vehicle types, they need to enroll in a driving school and pass additional tests to regain the original permitted vehicle types. Process for upgrading a driver's license: Enroll in a driving school with A-class training qualifications, provide ID card, household registration, five white-background color photos, and the original driver's license; pay the fee after enrollment approval; undergo legal training; after passing the legal test, take the field driving test (e.g., pole test); after passing the field test, take the road test, and wait for the upgrade to complete after passing the road test. Downgrading does not apply to small cars or motorcycles. It is important to note that if eligible for downgrading, only the highest-level permitted vehicle type can be downgraded at a time. For example, if holding a B1 and B2 level driver's license, only B1 will be downgraded first. Drivers holding licenses for large buses, tractors, city buses, medium buses, or large trucks will have their highest permitted vehicle type revoked by the vehicle management office under the following circumstances, and they will be notified to complete the downgrade and license replacement within 30 days: Being involved in a traffic accident resulting in death and bearing equal or greater responsibility, without constituting a crime. Having a full 12-point penalty in one scoring cycle. Failing to undergo inspection for three consecutive scoring cycles. If the driver fails to complete the downgrade and license replacement within the specified time, the vehicle management office will announce the revocation of the permitted vehicle type. After completing the downgrade and license replacement, if the driver applies to restore the revoked permitted vehicle type, they must not have a full 12-point penalty in the current and the most recent scoring cycle before application, nor have been involved in a traffic accident resulting in death with equal or greater responsibility. Process for downgrading the highest permitted vehicle type: After passing the relevant tests, receive the "Motor Vehicle Driver Illegal Full-Point Test Information Feedback Notice" (for A and B class licenses, the downgrade information will be noted on the notice). After the suspension period ends, bring the ID card and the notice to the traffic police department where the license was suspended to retrieve the driver's license. Submit the following documents to the issuing vehicle management office to complete the downgrade and license replacement (must have no pending traffic violations, processed within one working day): Original "Motor Vehicle Driver's License Application Form". Original and copy of the driver's ID. Original motor vehicle driver's license. Three recent half-length, front-facing, white-background color photos (submit a digital photo collection receipt if required locally).

Where is the AUX interface in Lexus UX?

The AUX interface in Lexus UX is located under the center armrest. Open the armrest to see it. The AUX is an audio input interface. Its basic working principle is that after connecting to the AUX interface, the audio from electronic devices can be transmitted to the car audio system via the headphone jack and AUX interface, allowing playback through the car audio broadcasting facilities. The USB interface can be used to insert a USB drive for audio playback. To use it, connect one end to the AUX interface and the other end to devices like smartphones, MP3 players, or MP4 players. This allows you to listen to songs or niche music anytime, anywhere, without being limited to car music CDs. However, if the playback device runs out of power, the music will stop (the interface is typically a 3.5mm standard headphone jack). Aux, short for Auxiliary, refers to an additional signal line design. In general audio equipment, besides the standard output and input terminals, there are often several terminals labeled Aux, serving as backup connection points. These can be used for special applications, such as additional audio output or input. Such backup terminals or lines, whether for input or output, are collectively referred to as Aux. Function: The AUX port is an asynchronous port, mainly used for remote configuration, dial-up connections, or connecting to a MODEM via a transceiver. It supports hardware flow control. The AUX port and CONSOLE port are usually placed together because they are used in different configuration environments. The AUX interface establishes a command-line connection between the user and the device, enabling operations that are typically impossible in user mode, such as initialization, restoring default settings, or correcting abnormal user modes. It provides a fixed port for the device, which can be used as a standard asynchronous serial port with a maximum speed of 115200bit/s. Using the AUX interface, remote configuration and line backup functions for hardware products can be achieved. Note: When using the AUX interface, ensure you purchase the correct connecting cable and avoid inserting the audio cable into the wrong port. It's best to follow the steps outlined in the product's user manual. If unsure, consult the product's official website or customer service hotline.

Does the Front of the Car Touching the Line During Reverse Parking in Subject 2 Result in Deduction?

Touching the line with the car body is considered as the car body crossing the line, which results in a 100-point deduction, making the test unsuccessful. Other actions that also result in a 100-point deduction include crossing the line with the car body, not completing the parking, stopping midway, not following the prescribed route, not following the sequence, and exceeding the time limit. The total score for both subjects is 100 points, with evaluation criteria set for failure, 20-point deduction, 10-point deduction, and 5-point deduction. The rules for the Subject 2 driving test for obtaining a motor vehicle driver's license state that any of the following actions will result in failure: stopping midway during the test, rolling back, not following the voice prompts, wheels crossing the line, or the car body touching the line. Many learners encounter the issue of touching the line during Subject 2 training, and the most common mistake leading to failure is "touching the line." The main reason for wheels touching the line is that learners fail to master the correct timing for steering. Besides missing the right moment to steer, another reason could be that the steering speed does not match the car's speed. Subject 2 Deduction Criteria: Not wearing a seatbelt: 100-point deduction. Starting the engine without the gear in neutral: 100-point deduction. Not using turn signals (including starting, changing lanes, overtaking, turning, and parking); using turn signals for less than three seconds (note that this is easily overlooked!); forgetting to turn off turn signals or using them incorrectly: 10-point deduction. Stalling once: 10-point deduction. Reverse Parking: Not following the prescribed route sequence: 100-point deduction. Car body crossing the line: 100-point deduction. Not completing the parking: 100-point deduction. Before reversing, not ensuring both front wheels pass the control line: 100-point deduction. Exceeding the 210-second time limit for the task: 100-point deduction. Stopping for more than 2 seconds midway: 5-point deduction each time. Slope Parking and Starting: After stopping, if the front bumper is not aligned with the pole line and exceeds 50 cm forward or backward: 100-point deduction. After stopping, if the front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward: 10-point deduction. After stopping, if the starting time exceeds 30 seconds: 100-point deduction. Wheels touching the road edge line while driving: 100-point deduction. Rolling back more than 30 cm when starting: 100-point deduction. After stopping, if the car body is more than 50 cm from the road edge line: 100-point deduction. Not tightening the parking brake after stopping: 10-point deduction per occurrence. After stopping, if the car body is more than 30 cm but less than 50 cm from the road edge line: 10-point deduction per occurrence. Rolling back more than 10 cm but less than 30 cm when starting: 5-point deduction per occurrence. Parallel Parking: After parking, if the car body crosses the line: 100-point deduction. Not using or incorrectly using turn signals when parking: 10-point deduction. Exceeding the 90-second time limit for the task: 100-point deduction. Car body touching the parking space edge line while driving: 10-point deduction per occurrence. Wheels touching the lane edge line while driving: 10-point deduction per occurrence. Stopping for more than 2 seconds midway: 5-point deduction per occurrence. 90-Degree Turn: Wheels touching the road edge line: 100-point deduction. Not using or incorrectly using turn signals during the turn, or not turning off turn signals after the turn: 10-point deduction. Stopping for more than 2 seconds midway: 5-point deduction per occurrence. Curve Driving: Wheels touching the road edge line: 100-point deduction. Stopping for more than 2 seconds midway: 100-point deduction. Not driving in second gear or above: 5-point deduction.
