The primary objective of the present proposal is to improve the efficiency of internal combustion engines (ICEs) through development of commercially feasible air-hybrid and fully variable valve timing system technologies. Although full electric and electric-hybrid concepts have received significant attention in the past decade, they require the addition of heavy, expensive batteries and electric motors to the ICE powertrain in order to store and convert kinetic energy generated during braking into mechanical power to propel the vehicle. Air-hybrid engines use the same concept as electric-hybrid vehicles; however, rely solely on compressed air directly available from the engine cylinders to store energy and therefore potentially offer significant weight and cost savings with equal efficiency.

本提案的主要目标是通过开发商业上可行的空气混合动力和完全可变气门正时系统技术来提高内燃机（ICE）的效率。虽然全电动和电混合概念在过去十年中受到了极大的关注，但它们需要向ICE动力系统添加重型，昂贵的电池和电动机，以便将制动期间产生的动能存储并转换为机械动力以推动车辆。空气混合动力发动机使用与电动混合动力汽车相同的概念;然而，仅依赖于直接从发动机气缸获得的压缩空气来存储能量，因此可能在同等效率的情况下显著节省重量和成本。
