HOWO exhaust brake switch is located on the left side of the clutch pedal. The introduction of exhaust brake is as follows: 1. Application of exhaust brake: Exhaust brake is widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe. The closure of this valve increases the pressure during the exhaust stroke, utilizing the generated negative pressure to obtain braking force. 2. Function of exhaust brake: The exhaust brake allows smooth engine exhaust when going downhill. 3. Principle of exhaust brake: The exhaust brake is implemented in the engine. Its principle is to close the engine exhaust channel, causing the engine piston to encounter gas back pressure during the exhaust stroke, thereby resisting engine operation and generating braking effect, ultimately achieving the purpose of controlling vehicle speed.

Under what circumstances is 100 points deducted for gear shifting?

Reasons for deducting 100 points during gear shifting in Subject 3: 1. Reason one: Looking down at the gear or failing to engage the gear twice in a row while driving; 2. Reason two: Coasting in neutral during the gear shifting process; 3. Reason three: Failing to smoothly shift up or down as instructed; 4. Reason four: Taking eyes off the driving direction for more than 2 seconds; 5. Reason five: Mismatch between gear and vehicle speed. If the clutch pedal is not fully depressed when shifting gears, and the next higher gear is engaged, the system will not detect the gear shift signal after the speed increases, assuming the vehicle is still in the lower gear, leading to a speed mismatch and resulting in point deduction.

What is the source of mortgaged vehicles?

The source of mortgaged vehicles is when the vehicle owner uses the car as collateral to a lending company or related platform and fails to repay the loan within the stipulated period. The lending company then sells the vehicle to others through debt transfer. Below is relevant information about mortgaged vehicles: 1. Regulations: Mortgaged vehicles can undergo normal annual inspections. The law explicitly states that for vehicles in a mortgaged or seized status, the department or individual holding the vehicle must conduct annual inspections on time. Mortgaged vehicles can normally purchase insurance through insurance companies, with the beneficiary being the owner who holds the right to use the vehicle. The purchase and claims process is no different from that of a regular used car. 2. Precautions: When purchasing a mortgaged vehicle, it is essential to inspect the vehicle's condition, including mileage, age, and overall state. Avoid purchasing mortgaged vehicles that have been involved in accidents.

What is the purpose of rev-matching during downshifting?

As the name suggests, rev-matching during downshifting involves "giving a little extra throttle" while downshifting to eliminate the speed difference between the engine and the transmission, ensuring that the engine speed matches the gear as closely as possible. This helps reduce the jerking sensation during downshifting. If the vehicle speed and gear are not matched, the meshing of gears during shifting can cause vibrations, leading to that jerking feeling. Additional info: When performed correctly, rev-matching does not harm the vehicle; in fact, it can reduce clutch wear to some extent. It's important not to give too much throttle during rev-matching—avoid pressing the accelerator too hard, as excessively high engine RPMs can cause the car to lurch forward. Rev-matching is a driving technique that requires practice to master for smooth downshifts.

Can You Drive with the Power Saver Enabled?

Yes. The power saver is enabled to prevent battery drain. Starting the engine and driving for a while will resolve the issue. This is a normal phenomenon caused by prolonged parking or excessive battery usage. Simply driving to recharge the battery will help. Below is some relevant information: 1. Types of power savers: system power saver, motor power saver, lighting power saver, air conditioning power saver, boiler power saver, oil pump power saver, etc. 2. Function: The motor power saver dynamically adjusts the voltage and current during motor operation through built-in specialized power-saving optimization software. Without altering the motor speed, it ensures the motor's output torque matches the load demand, effectively avoiding energy waste caused by the motor and eliminating scenarios of overcapacity or low-load operation.
