非道路用柴油机主要应用领域,包括拖拉机、收获机械、工程机械、低速货车、固定动力(发电和水泵等)和泵机等,环保性(排放)、经济性、动力性、舒适性(NVH)及可靠性是柴油机发展永恒的主题;增压中冷是柴油机未来发展方向,可以提高升功率、同样功率下可降低油耗和减小柴油机尺寸、还可以满足高排放要求;更高的喷射压力、灵活可靠的供油周期(开始时间、持续时间、多次喷射等)、多系统协同工作(EGR、VGT、电子节气门、电子风扇、后处理系统等)一直是柴油机技术进步追求的目标。由于不断严格的国内外排放和环保法规的执行,柴油机技术在近几年有了快速的发展。
The main application areas of non-road diesel engines include tractors, harvesting machinery, construction machinery, low-speed trucks, fixed power (power generation and water pumps, etc.) and pumps, environmental protection (emissions), economy, power and comfort (NVH) And reliability is the eternal theme of the development of diesel engines; turbocharger intercooler is the future direction of diesel engine, can increase the power, the same power can reduce fuel consumption and reduce the size of diesel engines, but also to meet the high emission requirements; higher injection pressure, Flexible and reliable fuel supply cycle (start time, duration, multiple injection, etc.), multi-system work together (EGR, VGT, electronic throttle, electronic fan, aftertreatment system, etc.) has been the pursuit of diesel engine technology. Diesel engine technology has seen rapid growth in recent years due to stringent domestic and international emissions and environmental regulations.
