How to switch between fuel and electric modes in BYD Qin?

BYD Qin can switch between fuel and electric modes by selecting different driving modes. The various driving modes for switching between fuel and electric in BYD Qin are as follows: 1. BYD Qin does not have a pure fuel mode: it can operate purely on electricity or in hybrid mode. 2. The driving modes of BYD Qin include: Pure Electric + Economy, Pure Electric + Sport, Hybrid + Economy, Hybrid + Sport, etc. In Pure Electric + Economy mode, the engine is not used, and the car runs on electricity. When the accelerator is pressed, the controller gradually increases the motor's current. In Pure Electric + Sport mode, the engine is also not used, and the controller directly supplies the motor with maximum current when the accelerator is pressed. In Hybrid + Economy mode, the engine is not used when the speed is below 40 km/h and the battery level is above 15%. When the speed exceeds 40 km/h, the engine automatically starts, providing only 10% of the power to the car. The controller still gradually increases the motor's current and charges the battery. If the speed is below 40 km/h and the battery level is below 15%, the engine will also start but will not provide power to the car, instead idling to charge the battery. As long as the speed remains below 40 km/h, the engine will automatically shut off once the battery is charged above 25%. In Hybrid + Sport mode, the engine can only be stopped or started manually, with the engine providing 100% power to the wheels, and the motor also operating at maximum power.

How to Align the Timing on a Chevrolet Cruze?

Aligning the timing on a Chevrolet Cruze primarily involves the following steps: 1. Align the crankshaft according to the marks on the crankshaft timing pulley, ensuring the No. 1 cylinder piston is at top dead center. 2. Install the camshaft timing pulley and align the marks on the camshaft; for dual camshafts, align both camshaft positions separately. 3. Install the new belt tensioner: Among the engine timing gears, only the camshaft gear has alignment marks, while the others do not. First, rotate the engine to bring cylinders 1 and 6 to top dead center. Then, assemble all gears except the camshaft gear, observing the marks on the engine block to align the camshaft gear mark with this mark. Subsequently, rotate the engine to approximately 22 degrees before top dead center, adjust the fuel injection pump to the state where the first cylinder just starts to inject fuel, and tighten the screws.

What is the normal tire pressure for small cars?

The normal tire pressure for small cars is generally between 1.8 and 2.4 atmospheres. Typically, the front tires should be between 2.1 and 2.3 atmospheres, while the rear tires should be between 2.3 and 2.4 atmospheres. Normal tire pressure varies by season: in winter, it is advisable to increase the standard tire pressure by about 0.2 bar; in summer, if the car is parked outdoors, the pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Generally, a tire pressure between 2.3 and 2.5 is considered normal. If the car is fully loaded, a tire pressure of around 2.5 is more suitable; for two passengers, a tire pressure of 2.3 is also normal. The standard pressure can usually be found in the following places: the vehicle user manual, the label next to the driver's door, the drawer beside the driver's seat, or the fuel tank cap door.

What is exhaust pipe resonance during throttle release?

Exhaust pipe resonance during throttle release can be addressed by modifying the muffler to a single-stage backpressure configuration. Exhaust pipe resonance: The muffler can be modified to a single-stage backpressure setup while placing steel wool inside the muffler. After this modification, the muffler's vibration frequency will change from vibrating three times per exhaust cycle to vibrating once. Additionally, the steel wool can absorb some of the exhaust gas energy, but the steel wool's vibrations won't transfer to the muffler housing. Muffler service life Therefore, after modification, the muffler housing will experience significantly fewer vibrations compared to before. Moreover, the modified muffler's service life will be doubled. This modification method can also be applied to construction machinery and agricultural equipment. With absolutely no moisture inside the modified muffler, it will never rust internally. If the steel wool near the exhaust port is compressed to block dust, it can reduce PM2.5 emissions by more than 20%.

What does license renewal and archiving mean?

License renewal and archiving means that the driver's license has been successfully reviewed and transferred. The full name of the driver's license is the motor vehicle driver's license, also known as a driving license or driver's permit, which is a legally required certification for motor vehicle drivers. The following conditions must be met for license renewal and inspection: Holders of large passenger vehicle, tractor, city bus, medium passenger vehicle, or large truck driver's licenses have no demerit points in the current scoring cycle, or holders of other permitted vehicle-type driver's licenses have less than 12 demerit points in the current scoring cycle; Holders of large passenger vehicle, tractor, city bus, medium passenger vehicle, or large truck driver's licenses who have demerit points in a scoring cycle, as well as holders of other permitted vehicle-type driver's licenses who have been involved in a traffic accident resulting in death and assumed equal or greater responsibility without having their motor vehicle driver's license revoked, and have completed the required inspection education; The applicant has no pending road traffic safety violations or traffic accidents; The applicant's physical condition meets the driving permit requirements; The motor vehicle driver's license is not under any circumstances of being seized, detained, temporarily suspended, revoked, canceled, or annulled by law.

What is the capacity of the starter battery for new energy electric vehicles?

New energy electric vehicle starter batteries include nickel-metal hydride batteries with 80A.h, nickel-cadmium batteries with 55W.h/kg, and sodium-sulfur batteries with 760W.h/kg. Introduction to Nickel-Metal Hydride Batteries: Ovonie currently offers two types of unit batteries: 80A.h and 130A.h, with a specific energy of 75–80W.h/kg and a cycle life exceeding 600 cycles. Introduction to Nickel-Cadmium Batteries: Their specific energy can reach 55W.h/kg, and specific power exceeds 190W/kg. Introduction to Sodium-Sulfur Batteries: Their theoretical specific energy is 760W.h/kg, with practical values already exceeding 100W.h/kg, which is 3–4 times that of lead-acid batteries. Another feature is their ability to discharge at high currents and power. Their discharge current density can generally reach 200–300mA/mm2, and they can instantaneously release three times their inherent energy. Additionally, they have high charge-discharge efficiency.
