Under standard load conditions on normal roads, an ordinary semi-trailer typically consumes between 36L to 40L of fuel per 100 kilometers. Here is an introduction to semi-trailers: Introduction: A semi-trailer is a trailer with axles placed behind the vehicle's center of gravity and equipped with coupling devices that transmit both horizontal and vertical forces to the towing vehicle. Classification: Dump semi-trailer: Dump semi-trailers are suitable for transporting bulk and loose cargo such as coal, ore, and construction materials. Low-bed semi-trailer: Low-bed semi-trailers have no side panels on the cargo area and are widely used for medium to long-distance freight transport. Skeleton semi-trailer: Skeleton semi-trailers feature a fence structure design on the cargo area and are mainly used for transporting agricultural products and other lightweight goods.

I've driven semi-trailers myself, and the actual fuel consumption does fluctuate quite a bit. For the 13-meter refrigerated semi-trailer I often drive, maintaining a steady speed on national highways consumes about 35 liters per 100 kilometers. But when hauling fresh produce and rushing on highways at 110 km/h, it can spike to 42 liters. Last time, transporting fruit from Yunnan on mountain roads with the refrigeration running non-stop, the gauge showed a whopping 48 liters. Veteran drivers know that wind resistance becomes the main fuel guzzler once speed exceeds 80 km/h. The air deflector I installed saves nearly 2 liters. Many new trucks now come with hydraulic retarders, and using brakes less on downhill stretches really saves fuel. The Shacman I switched to last year saves about 5 liters per 100 kilometers compared to my old truck.

What are the causes of unstable engine idle speed?

Reasons for unstable engine idle speed: oil accumulation and carbon deposits in the throttle valve, dirty intake passages, clogged fuel system represented by fuel injectors, intake pipe malfunctions, weak sparks caused by individual spark plug failures, etc. The following is a detailed explanation of unstable engine idle speed: 1. Oil accumulation and carbon deposits in the throttle valve, dirty intake passages: Blocked intake passages can cause idle speed fluctuations, and carbon deposits or oil in the throttle valve are the most common causes of unstable idle speed. 2. Clogged fuel system represented by fuel injectors, intake pipe malfunctions: When the fuel system, especially the fuel injectors, is clogged, it leads to insufficient fuel supply pressure, poor fuel atomization, an imbalanced air-fuel mixture ratio, and incomplete combustion, resulting in related malfunction symptoms.

What is the Departure Angle of a Car?

Departure angle refers to the angle between the tangent line drawn from the rearmost protruding point of the car to the rear wheels and the road surface when the car is fully loaded and stationary. In other words, it is the maximum angle between the horizontal plane and the plane tangent to the outer edge of the rearmost wheel tire (under static load). Additional information is as follows: 1. Location of departure angle: It is located on any rigid component fixed to the vehicle behind the rearmost wheel and must not be below this plane. 2. Significance of departure angle: It indicates the car's ability to avoid collision when leaving obstacles (such as small hills, ditches, etc.). The larger the departure angle, the better the car's off-road capability.

What should be paid attention to when a vehicle is parked for a long time?

When a vehicle is parked for a long time, the following should be noted: clean the items inside the vehicle before parking, choose a suitable parking location, protect the battery, protect the vehicle tires, properly store the vehicle keys, and conduct a comprehensive inspection before using the vehicle after long-term parking. Additional details are as follows: 1. Clean the items inside the vehicle before parking: Remove food, beverages, packaging bags, and other items to prevent mold; do not leave flammable or explosive items such as alcohol or lighters in the vehicle; avoid placing objects with convex lens effects, such as mineral water bottles, as they may focus sunlight to a single point in the vehicle under sunlight, posing a fire risk. 2. Choose a suitable parking location: If there is a garage, park inside. If not, try to find a dry, ventilated, shaded, and rain-protected area to park, or use a car cover for protection. This helps protect leather, rubber, and the vehicle's surface, preventing metal components of the chassis from rusting due to moisture. 3. Conduct a comprehensive inspection before using the vehicle after long-term parking: Check the engine compartment and the underside of the vehicle for small animals, such as rodents that may have chewed through wiring or pipes, and observe the ground beneath the vehicle for water or oil stains; check if the lights are functioning properly, such as the brake signal lights at the rear; inspect the tires for deformities, cracks, bulges, and ensure the tire pressure is normal to avoid accidents.

Is It Illegal to Drive with the Trunk Open?

What does engine start-stop mean?

Engine start-stop is a very practical automotive energy-saving and emission-reduction technology. It automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. Below is a detailed explanation of engine start-stop: 1. At a red light: The system can automatically shut off the engine, and when the car needs to move forward again, the system can automatically restart the engine. 2. The main function of the engine: To increase pressure and improve air intake, aiming to achieve high power output and make the car more powerful.

What does TC mean when displayed in a car?

When the "TC" indicator light on the car dashboard flashes, it means the "Traction Control System" is active. Here is an introduction to the traction control system: 1. Function: When the ABS anti-lock system detects that some wheels are slipping, the traction control system will apply braking to the slipping wheels to prevent the loss of traction on those wheels. When the system is active, the yellow TC indicator on the dashboard flashes to alert the driver. 2. Principle: The traction control system relies on electronic sensors to detect when the driven wheel speed is lower than the driving wheel (a sign of slipping). It then sends a signal to adjust ignition timing, reduce throttle opening, decrease throttle input, downshift, or brake the wheels to prevent further slipping.
