8V128D发电用柴油机的研制

Development of 8V128D Generating Diesel Engine

以车用柴油机8V128Q型为基础开发发电用柴油机8V128D型。通过采用重新匹配增压器,调整配气正时,优化燃油系统,改进活塞结构和提高主要运动件强度等手段,使增压器效率得到提高,燃烧得到改善,降低了柴油机的机械负荷,提高了柴油机的强度,最终达到提升柴油机功率,降低油耗和排温的目的。台架试验显示:所开发的8V128D型柴油机取得了较好的性能指标和可靠性指标。

The generating diesel engine 8V128D was developed on the basis of the vehicle diesel engine 8V128Q. Through re-matching of the turbocharger, adjusting valve timing, optimizing the fuel injection system, improving the structure of pistons and the strength of the main moving parts, the turbocharger efficiency was improved, the combustion optimized, the mechanical load reduced and the strength of the engine improved, thus finally achieved the goal of improving power, reducing fuel consumption and exhaust temperature of the diesel engine. Bench test shows that the 8V128D engine achieves better performance and reliability.
