Air powered start-up system for natural gas bus reaches 23km/h starting speed, and gets more than 30% energy-saving rate.
Based on international advanced air powered start technology (APST) and automatic start stop technology (ASST), Jiaoda Shenzhou air powered start-up system adopts hydraulic mechanical drive theory and the law of conservation of mechanical energy, collects the wasting kinetic energy and idle energy, converts them into potential energy, storages the energy by air compression. When the vehicle/device starts, releases the energy from the compressed air, converts them into kinetic energy, actuates hydraulic motor, drives vehicle moving. This technology decreases vehicle and device fuel consumption and emission markedly, and especially suitable for frequent brake, frequent start and gridlocked traffic.

Significant effect of energy conservation and emission reduction: more than 30% natural gas saving rate and reducing wear and tear of gearbox.

Driving comfortable: has semi-conservation transmission function, stable starting and largely reducing labor intensity.
Reliability: simple and dependable mechanical structure, designed with full consideration of safety, testing under years of high intensity bus operating in the field. With automatic start-stop control technology, it has auto brake when there is accident.
Flexible installation: installed in the new bus from production line as well as the used bus under the operation.

System structure
The air powered start-up system is composed of hydraulic motor/pump, hydraulic accumulator, combination hydraulic control valve, dynamic hybrid transmission and ECU controller.
