Motorcycles failing to start without using the choke in summer is due to poor atomization effect of the carburetor, which can be resolved by replacing the carburetor. Below are specific details about the carburetor: Introduction: The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine's operation. As a precise mechanical device, it utilizes the kinetic energy of the incoming airflow to atomize the gasoline. Function: A complete carburetor setup should include a starting device, idle device, medium load device, full load device, and acceleration device. The carburetor automatically adjusts the mixture concentration and outputs the corresponding amount of air-fuel mixture according to the engine's different operational states. To ensure a more uniform mixture, the carburetor also has the effect of atomizing the fuel to support the machine's normal operation.

What are the lane rules for motorcycles?

There are 4 key points regarding motorcycle lane rules: 1. Full observation when turning right: Before making a right turn, exercise caution and check for approaching vehicles, as collisions may occur between right-turning cars and oncoming motorcycles; 2. Special attention at intersections: When approaching intersections, follow safety procedures by coming to a complete stop, observing posted traffic signs and signals, scanning for approaching traffic from both directions, and proceeding slowly; 3. Safe passing: When cars pass motorcycles, wind turbulence may destabilize the motorcycle. Always use turn signals before changing lanes so motorcyclists can anticipate traffic movements and position themselves safely; 4. Weather awareness: Strong winds make motorcycle control difficult, while rain or snow reduces visibility both for the rider and of the motorcycle to other drivers.

What license plate does BYD DM-i use?

BYD DM-i uses a green license plate. BYD DM-i: Essentially, DM-i is a combination of range extension and direct drive. At medium and low speeds, the generator first converts fuel into electricity, which is then used to power the electric motor. Any excess electricity is stored in the battery. Benefits of electric motor drive: The internal combustion engine always operates at high-efficiency RPM, maintaining thermal efficiency at its theoretical peak. Generating electricity first and then using it to drive the electric motor results in a transmission efficiency (based on BYD's hardware setup) that is higher than most transmissions, except for dry dual-clutch transmissions. This includes AT transmissions, CVT transmissions, and some wet dual-clutch transmissions. The energy loss in automatic transmissions is much greater than commonly perceived.

What is the transmission brand of the Hyundai Custo?

The transmission brand of the Hyundai Custo is Mobis. The classification of automotive transmissions: Divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations. Introduction to transmissions: A transmission is essentially a gearbox containing numerous gears. The driving gear (connected to the engine via the clutch) receives power from the engine to drive the driven gear (connected to the wheels via the final drive and drive shaft), thereby propelling the wheels. Each gear has a pair of driving gears, and engaging a specific gear means that particular pair of gears is combined to transmit power.
