2025 Chem-E-Car Competition® China Regional Event, under the auspices of the Chemical Industry and Engineering Society of China (CIESC) , epitomizes the synergy between chemical reactions and systems engineering. Participating teams are tasked with designing, making, and operating miniature vehicles powered exclusively by controlled chemical reactions. Through precise modulation of reaction rates, energy transduction mechanisms, and mechanical architectures, competitors executemission-critical operations including load-bearing movement and sub-millimeter-grade distance modulation within limited situation. The event concentrates on cross-disciplinary synthesis, spanning mechanism optimization, non-electronic control, safety compliance engineering, and systemic error attenuation, thereby cultivating participants' capacity to extrapolate foundational chemistry into chemical engineering application. Premier teams earn eligibility to ascend to the global arena, engaging in intellectual discourse with international counterparts tomanifest the pinnacle of emergent engineering acumen.
