Should the Choke Be Open or Closed for a Gasoline Engine?

When a gasoline engine is operating, the choke should be open. Advantages of gasoline engines: Gasoline engines are lighter than diesel engines, have lower manufacturing costs, produce less noise, and offer better cold-start performance. However, they have lower thermal efficiency and higher fuel consumption rates. For lightweight and cost-effective applications such as motorcycles, chainsaws, and other small-power machinery, two-stroke air-cooled gasoline engines are commonly used. Stationary small-power gasoline engines, which prioritize simplicity, reliability, and lower costs, mostly use four-stroke water-cooled designs. Passenger cars and light trucks predominantly use overhead valve water-cooled gasoline engines. However, with increasing emphasis on fuel efficiency, diesel engines are becoming more common in these vehicles. Small aircraft engines, which require lightweight and high power-to-weight ratios, mostly use air-cooled gasoline engines with hemispherical combustion chambers. Differences between gasoline and diesel engines: In a gasoline engine, the air-fuel mixture ignites and burns instantaneously, releasing energy. This allows the cycle to be repeated multiple times per unit of time, enabling high-speed operation to deliver high power. As a result, gasoline engines can achieve high performance and quick response with compact size and light weight. The broad RPM range also provides better handling feel. In contrast, diesel engines require a certain amount of time for combustion after fuel injection, making them more suitable for lower RPMs to ensure complete fuel combustion and deliver high torque. To withstand the high pressure and torque in the cylinders, diesel engines have stronger components such as cylinders, pistons, and connecting rods, making them heavier and bulkier than gasoline engines.

Are Lynk & Co Engines the Same as Volvo's?

Lynk & Co and Volvo engines are not exactly the same, with some differences in tuning. Lynk & Co vehicles primarily use two types of engines: a 1.5-liter turbocharged three-cylinder engine and a 2.0-liter turbocharged four-cylinder engine. Lynk & Co is a premium luxury brand jointly established by Geely and Volvo. The Lynk & Co 03 is a compact SUV under the Lynk & Co brand. Taking the Lynk & Co 03 2021 1.5TD Manual Pure Lite version as an example, its dimensions are 4639mm in length, 1840mm in width, and 1472mm in height, with a wheelbase of 2730mm, and a body structure of a 4-door, 5-seater sedan. In terms of power, the Lynk & Co 03 2021 1.5TD Manual Pure Lite version is equipped with a 1.5L turbocharged engine, delivering a maximum power of 115kW and a maximum torque of 245Nm, paired with a 6-speed manual transmission.

What Causes the Ticking Sound in the Boyue's Engine?

The reasons for the ticking sound in the Boyue's engine: 1. Cold start noise; 2. Noise from the carbon canister solenoid valve operation; 3. Aging or loosening of engine mounts; 4. Overly rich air-fuel mixture; 5. Piston slap noise. The Boyue is a compact SUV under Geely Auto. Taking the Boyue 2021 Million Edition 1.8TD Manual Two-Wheel Drive Comfort Model as an example, its dimensions are 4519mm in length, 1831mm in width, and 1694mm in height, with a wheelbase of 2670mm. In terms of power, the Boyue 2021 Million Edition 1.8TD Manual Two-Wheel Drive Comfort Model is equipped with a 1.8L inline four-cylinder turbocharged engine, delivering a maximum power of 120kW and a maximum torque of 250Nm, paired with a 6-speed manual transmission.

How to Fix Black Smoke from an EFI Diesel Vehicle?

Repair methods for black smoke from an EFI diesel vehicle: 1. Remove the air filter and observe the exhaust smoke color. If the black smoke condition improves, the issue is caused by severe contamination of the air filter; 2. Check if the fuel supply timing is too early and adjust if necessary; 3. During engine operation, conduct a cylinder-by-cylinder fuel cut-off test. When a cylinder is cut off, if the engine speed decreases, black smoke significantly reduces, and knocking sounds weaken or disappear, it indicates excessive fuel supply to that cylinder. Inspect the injector of that cylinder. An EFI diesel vehicle is equipped with an electronically controlled fuel injection and emission diesel engine. The injection system of an EFI diesel engine consists of three parts: sensors, ECU, and actuators. Its task is to electronically control the fuel injection system, enabling real-time control of fuel injection quantity and timing according to operating conditions.

What Causes the Abnormal Noise When an Automatic Transmission Car Starts at Low Speed?

"The causes of abnormal noise when an automatic transmission car starts at low speed include: engine failure, transmission failure, and door wear. Below is a detailed explanation of the above causes: Engine failure: Abnormal noise from the engine indicates a problem in the engine compartment, such as a metallic screeching or whistling sound, mainly caused by excessive wear of some parts or improper assembly and adjustment. Therefore, when the engine makes abnormal noises, it should be repaired promptly to prevent the fault from worsening. Transmission failure: If there is a "rustling" sound inside the transmission while driving, which disappears when the clutch or accelerator pedal is pressed, and a whistling-like sound occurs during gear shifting, the transmission should be repaired immediately. Door wear: When stepping on the accelerator or brake, there might be some abnormal noises from certain parts of the car body, mainly due to lack of lubrication in the door. However, it is necessary to determine whether the noise comes from the door hinge position or the internal components of the door, such as the window regulator, door lock mechanism, or handle mechanism. If the noise is from the door hinge or limiter, a specialized door hinge and slide lubricant can be used. For the internal components like the window regulator, door lock mechanism, or handle mechanism, a specialized door accessory lubricant should be used."

What lights should be turned on when temporarily parking a car?

During the day, no lights are required for temporary parking of a car. At night, temporary parking requires turning on the hazard warning flashers, clearance lights, and rear position lights. Hazard warning flashers, commonly referred to as emergency lights or hazards, are signal lights that alert other vehicles and pedestrians to pay attention to the special situation of the vehicle. Clearance lights are the outermost lights at the front and rear of the vehicle. Front and rear position lights, commonly known as parking lights or width markers, are also called side marker lights. Temporary parking refers to a brief stop on the right side of the road in the direction of traffic on a non-prohibited parking road surface, with the driver not leaving the vehicle. Regarding the temporary time concept, there is no specific duration defined; as long as the driver does not leave the vehicle during the brief stop, it is considered temporary parking.
