Jianghuai Ruijie and Cummins engines differ in terms of parent company, displacement, and application. Parent Company: Cummins engines are designed and manufactured by Cummins Inc. Jianghuai Ruijie engines are produced by Jianghuai Automobile Co., Ltd. Engine Company. Displacement: Cummins engines have a displacement range of 1.4-91 liters, with power output ranging from 31-3500 horsepower. Jianghuai Ruijie engines cover gasoline engine displacements of 1.0-2.4L and diesel engine displacements of 1.9-3.0L. Application: Cummins engines are widely used in heavy-duty trucks, medium-duty trucks, buses, recreational vehicles, light commercial vehicles, and pickup trucks for highway use, as well as in engineering machinery, mining equipment, agricultural machinery, marine, and railway applications for non-highway equipment. Jianghuai Ruijie engines are a key powertrain component under Jianghuai Automobile's brand - GREENJET. Jianghuai Automobile's engine lineup includes five gasoline and diesel platform products that provide powertrain solutions for sedans, SUVs, MPVs, light trucks, multi-purpose commercial vehicles, bus chassis, and pickup trucks.

I've driven quite a few vehicles equipped with JAC Ruijie engines, especially pickup trucks and light-duty trucks. I feel its design focuses more on economic practicality, with smooth power output but slightly weaker explosive force. In comparison, Cummins engines are often used in heavy-duty trucks or construction vehicles for high-intensity operations, featuring fast start-up response, slightly louder noise but extremely high durability. The fundamental difference lies in core technology and application scope: Ruijie engines are mostly domestically developed in China, with lower costs and fuel consumption, suitable for daily transportation; Cummins uses more imported components, with stronger horsepower and heavy-load endurance, ideal for long-distance freight or construction sites. As a user, Ruijie offers cheaper maintenance and easier-to-find parts; Cummins is slightly more expensive but has fewer breakdowns, making it more worry-free in the long run. When choosing, consider the workload intensity—for light loads, choose Ruijie to save money; for heavy loads, Cummins is more reliable.

What causes the buzzing sound from the right rear wheel after turning off the engine?

This is a normal phenomenon. It is the sound of the exhaust pipe contracting, and the noise will disappear after a few minutes. Models equipped with electronic parking brakes may also experience this situation, which is the sound of the electronic parking brake motor and is also normal. Below are specific details about electronic parking brakes: 1. Principle: The working principle of electronic parking brakes is similar to that of mechanical handbrakes. Both essentially create friction between the brake disc and brake pads to achieve parking brake purposes, except that the traditional mechanical handbrake lever has been replaced by an electronic button. 2. Function: The parking brake is achieved through electronic control. Additionally, it extends to the vehicle's auto-hold function, allowing the driver to avoid prolonged braking when parking, effectively preventing the vehicle from rolling.

What to Do If One Tire Always Has Low Pressure?

A solution for a tire that always has low pressure is to inspect and repair the tire. The effects of low tire pressure include: 1. Increased contact area between the tire and the ground, leading to abnormal tire temperature; 2. Severe deformation of the tire sidewall, accelerating the aging of internal steel wires and fabric layers, which can cause a blowout; 3. Increased fuel consumption; 4. Reduced tire lifespan. The functions of a tire are: 1. To cushion the impact experienced during driving; 2. To ensure good ride comfort and smooth driving; 3. To maintain good adhesion between the wheel and the road surface, improving traction, braking, and passability; 4. To bear the weight of the vehicle.
