Two Howo 6x4 dump trucks shipped to Rwanda.

During Rwanda's dry season, dust is prevalent, and sand ingress is a primary cause of engine cylinder scoring. Aorun has equipped these two Howo 6x4 dump truck with genuine desert-spec air filters; boasting a filtration efficiency of 99.9%, these filters significantly extend the service life of the piston rings and cylinder liners while reducing maintenance frequency.

Although there is a large installed base of HOWO vehicles in Rwanda, high-quality genuine parts remain in short supply. Aorun addresses this challenge by providing a complimentary 2,000-hour spare parts kit with every vehicle—including filters, belts, brake pads, and hydraulic oil seals—thereby ensuring that customers incur "zero maintenance costs" during the first six months of operation.
