As we all know, the factors that determine whether a vehicle is fuel-efficient include three kinds: the application of new materials to achieve lightweight vehicles, the use of aerodynamics to reduce the drag coefficient during driving, and the use of engine technology to reduce fuel consumption. Today, let the reporter of China Truck Network lead everyone through the Weichai light engine to learn about an engine's fuel-saving technology - low-speed high-torque technology. Before understanding the benefits of low-speed, high-twist, let's first look at what speed is, what torque is, and what the relationship between them is. Rotation speed refers to the number of revolutions around the center of the circle per unit time of the object that rotates. The common unit is rpm, which is the number of engine crankshaft rotations in one minute. The lower the engine's operating speed, the lower the energy loss due to wear of the piston and cylinder per unit of time. The maximum speed of common light diesel engines is around 3600 rpm, which can output 120 hp. Weichai WP3 can output 130 horsepower with a maximum speed of 3000 rpm. Compared with other light engines with the same power, Weichai light engine can reduce wear 600 times per minute compared to similar engines. This can both extend the overhaul mileage of the engine and reduce fuel waste during the work process. Torque is the force that rotates an object. The engine torque refers to the torque output from the crankshaft side of the engine. In actual driving, the torque parameter is the performance of vehicle acceleration and climbing ability. Large torque can ensure that the vehicle starts under various conditions such as climbing and overloading, and the acceleration power is sufficient. Each start acceleration will let you win. starting point. Under the condition that the engine power is fixed, the torque of the engine has a non-linear relationship with the rotational speed. Before the engine outputs the maximum torque, the output torque of the engine will increase with the increase of the rotational speed of the engine, but the degree of increase will vary with the engine. Variety. Low-speed, high-twist refers to the engine's linear relationship improving engine torque as speed increases before maximum torque is output, allowing the engine to output more torque at lower speeds. Since the average truck driver is accustomed to exercising between 1200 and 2,000 revolutions per minute (rpm), the Weichai WP3 series of light engines can deliver 350 N.m of torque at 1600 rpm. This means that it can better adapt to the driver's driving habits, and reserves sufficient torque reserve within the economical speed to ensure that the vehicle does not decelerate to a complex road during driving and saves fuel. Compared with other competing products, in the case of 130 horsepower, the Weichai WP3 has a relatively low engine speed. This also means that the Weichai lighter can output more torque at higher speeds, allowing the vehicle to run at high speeds. Under the circumstances, it is still possible to accelerate overtaking at will. The Weichai light machine is able to easily handle complex road conditions and keep the vehicle running at a constant speed thanks to its sufficient torque reserve. Weichai Light's high torque platform is just in line with the driving habits of most drivers. It is enough to make the vehicle start faster, and the acceleration time is shorter. It reduces the time waste in the transportation process, and the multi-dragging run saves cost. This is also the basic reason why Weichai light machine is suitable for inter-city logistics. In the road test of Yuxi City, Puxi City, near the 200km high-speed road section of Pujiang City, the handsome bell light truck with Weichai WP3 engine is on the high-speed mountain road. The start and acceleration are all 1-2 seconds faster than the conventional power model; the maximum speed The 116 is 3km/h higher than it; the average fuel consumption under full load test is 0.5L lower than that of the conventional power model, and the combined fuel consumption is 0.8L, which is undoubtedly superior to the similar products. We believe that with the switch of the Fourth National Regulations and the rapid development of the high-end light truck industry, users' demand for engine power, economy and reliability will continue to increase. High-speed and low-torque engine fuel-saving technologies will definitely become fuel-efficient for trucks. The main technology trend, Weichai can seize the opportunity to launch Weichai light machine at this time, will become the leader in a new generation of engine production companies.
