What are the steps for parking with an automatic electronic handbrake?

The steps for parking with an automatic electronic handbrake are: 1. After stopping the vehicle, shift to N gear; 2. Engage the handbrake; 3. Shift to P gear and turn off the engine. The electronic handbrake, also known as the Electronic Parking Brake (EPB), integrates temporary braking during driving with long-term parking braking, controlled electronically. The electronic handbrake extends from basic parking functions to include the AUTO HOLD feature. The application of AUTO HOLD technology eliminates the need for drivers to maintain prolonged braking when the vehicle is stationary.

Which Gear to Use for Reversing in an Automatic Transmission Car?

Automatic transmission cars use the R (Reverse) gear for reversing. The gear positions in an automatic transmission car, from top to bottom, are as follows: 1. P (Park) gear is for parking; 2. R (Reverse) gear is for reversing; 3. N (Neutral) gear is for neutral; 4. D (Drive) gear is for forward movement, with D1 and D2 being specialized gears for long uphill and downhill drives. The gear selector in an automatic transmission car is equivalent to the gear lever in a manual transmission and is mostly located on the floor. Generally, automatic transmission cars have the following gear positions: P (Park), R (Reverse), N (Neutral), D (Drive), S or 2, which is the second-speed gear, and L or 1, which is the first-speed gear. Correct usage of these gear positions is particularly important for those driving automatic transmission cars.

What are the advantages of a rotary engine?

The advantages of a rotary engine are high rotational speed with large power output, relatively lightweight, and fast throttle response. These are the three prominent advantages of a rotary engine. Because the rotary engine operates by rotation, unlike conventional piston engines (excluding aircraft radial engines) which perform reciprocating motion, the rotary engine has much less vibration and its size is easier to control. Due to the low inertia of the rotor, the rotary engine can quickly increase its rotational speed, resulting in excellent acceleration performance. The disadvantages of the rotary engine are high fuel consumption and heavy pollution. Due to the lack of a high compression ratio like reciprocating engines, combustion cannot be very efficient. Although Mazda once added single turbocharging and twin turbocharging to the rotary engine, it only increased horsepower output and moderately reduced exhaust emissions, still falling far short of reciprocating engines.

How to Use Exhaust Brake?

Exhaust brake usage method: When the accelerator pedal is at zero position and the fuel injector stops injecting fuel, the exhaust brake will automatically turn off if the accelerator or clutch pedal is pressed. This prevents the engine from stalling when stopping and ensures the exhaust brake does not activate during fuel injection. Exhaust brakes are widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe, and by closing this valve, the pressure during the exhaust stroke is increased, utilizing the generated negative pressure to obtain braking force. The regulating valve is generally driven by a control mechanism using compressed air or vacuum, and in most cases, it shares the same power source as the main brake system.

What are the disadvantages of automatic tire repair fluid?

Automatic tire repair fluid has the following disadvantages: 1. After using the repair fluid, it will have a certain impact on the wheel's dynamic balance; 2. Generally, within half a year after using the repair fluid, the residual fluid in the tire needs to be cleaned and the valve core replaced, otherwise it will affect the effectiveness of the next use; 3. The repair fluid can only fix small punctures, and cannot repair punctures larger than 6mm or extensive scratches; 4. The rubber protective film formed on the tire surface after use will affect the grinding and adhesion process in future tire repairs; 5. There is no rubber covering layer formed by the repair fluid on the tire sidewall, so punctures on the sidewall cannot be repaired. Tire repair fluid is an emergency product used when the tire is punctured and loses air, and there are no immediate repair conditions available.

What transmission does the Soueast DX3 use?

The Soueast DX3 is equipped with a transmission from Punch Powertrain, a Belgium-based energy-efficient powertrain system supplier headquartered in Sint-Truiden. With over 50 years of experience in designing and manufacturing continuously variable transmissions (CVTs), Punch also specializes in developing, producing, and supplying components for hybrid vehicles (48V and plug-in hybrid PHEV) and dual-clutch transmissions (DCT). The manual version of the Soueast DX3 features a 5-speed manual transmission, while the automatic variant comes with Punch's third-generation 8-speed CVT automatic transmission (with Sport and Snow modes). The transmission in the Soueast DX3 performs exceptionally well. When using the Soueast DX3's transmission in daily driving, pay attention to the following points: Do not delay transmission fluid changes for extended periods. Although many modern vehicles claim to have maintenance-free transmission fluid, this does not mean it never needs replacement. Prolonged use of old fluid can damage internal components like bearings and the transmission housing. Avoid prolonged coasting in neutral. While some experienced drivers of manual transmission vehicles may coast in neutral, doing so in an automatic can cause overheating. Re-engaging Drive (D) after coasting may also create harsh gear engagement. Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers attempt smooth gear changes by shifting into opposite gears while still moving, which causes significant wear to transmission gears and may lead to gear grinding over time. Avoid frequent steep hill climbs in Drive (D). Automatic transmissions may overheat under heavy load during steep ascents or upshift prematurely, resulting in insufficient power. Use manual mode to maintain lower gears or engage Sport mode to protect the transmission. Do not tow the vehicle long distances. If the automatic transmission vehicle breaks down, use a flatbed tow truck with the transmission in Neutral (N). Never tow the vehicle directly using tow ropes or similar methods.
