几年前,MTU公司开始了一项以396-03系列产品发动机(缸径/冲程为165/185mm,2100r/min时最大功率120kW/缸)为基础的研究计划,目的是使所有各种用途的产品降低燃油消耗,并且使那些用于对环境保护有严格要求的发动机大大降低氮氧化物。 用1500r/min的固定式发动机作为例子来详细叙述通过不断优化燃烧过程所获得的研究成果(在低NO_x排放时燃油消耗降低约5％,或者降低NO_x50％而不增加燃油消耗)。对于这种发动机来说,燃油消耗和NO_x两者是同等重要的。除了进行单缸机和六缸机的研制试验外,研究方法还包括研究和发展工作的预先计算和热力学分析(实际循环计算)。 同时,通过这个计划所取得的成果即改进的燃油喷射系统已经用于396-03发动机(系列生产定于1985年开始)。
A few years ago, MTU started a research program based on the 396-03 series engines (maximum cylinder diameter / stroke of 165 / 185mm, maximum power of 120kW / cylinder at 2100r / min), which aims to make all kinds of The products reduce fuel consumption and greatly reduce nitrogen oxides for those engines that are used for the strict protection of the environment. A 1500-rpm fixed engine is used as an example to describe the research results achieved through continuous optimization of the combustion process (about 5% reduction in fuel consumption at low NO x emissions, or NO x 50% reduction without increasing fuel consumption). For this engine, both fuel consumption and NOx are equally important. In addition to the development of single-cylinder and six-cylinder machines, research methods include pre-calculation and thermodynamic analysis of research and development work (actual cycle calculations). At the same time, the results achieved through this program, the improved fuel injection system, have been used for the 396-03 engine (serial production scheduled to begin in 1985).
