Abstract:
Reducing fuel consumption and thus CO2 emissions is one of the most urgent tasks of current research in the field of internal combustion engines. Water Injection has proven its benefits to increase power or optimize fuel consumption of passenger cars. This technology enables knock mitigation to either increase the engine power output or raise the compression ratio and efficiency while enabling λ = 1 operation in the complete engine map to meet future emission targets. Current systems have limited container capacity. It is necessary to refill the water tank regularly. This also means that we cannot get the benefits of an engine with a higher compression ratio. For this reason, the self-contained system was investigated. This article is a methodology for finding the right design of a self-contained water injection system, but also a vehicle test that proves the function.
摘要:
降低燃料消耗并因此降低CO2排放是内燃机领域当前研究的最紧迫任务之一。注水已证明其在增加动力或优化乘用车油耗方面的优势。该技术使得爆震减轻能够增加发动机功率输出或提高压缩比和效率,同时使得能够在完整的发动机图中进行λ=1操作以满足未来的排放目标。目前的系统限制了集装箱的容量。有必要定期补充水箱。这也意味着我们无法获得具有更高压缩比的发动机的好处。出于这个原因,对独立系统进行了调查。本文是一种找到独立注水系统正确设计的方法,但也是证明功能的车辆测试。
