淄柴N350/S雙燃料發(fā)動機，是中速直列四沖程大功率LNG/柴油雙燃料發(fā)動機；隨著排放法規(guī)的日趨嚴格和石油能源日益短缺，節(jié)能、低碳成為內(nèi)燃機技術發(fā)展的主導方向，液化天然氣（LNG）具有能量密度高、排放低（可有效降低NOx排放）等特點，對推動我國產(chǎn)業(yè)轉(zhuǎn)型升級和國家能源結(jié)構調(diào)整，具有重要的現(xiàn)實意義。
N350/S雙燃料發(fā)動機在N350柴油機的基礎上，增加了天然氣進氣系統(tǒng)和控制系統(tǒng)，主要包括天然氣進氣管、電子控制單元（ECU)、傳感器等?！350/S雙燃料發(fā)動機不改變N350柴油機具有的各個系統(tǒng)，可靠性高。
N350/S雙燃料發(fā)動機控制邏輯主要包括天然氣噴射控制、負荷控制、調(diào)速控制、安保控制等。N350/S雙燃料發(fā)動機通過控制程序設計及曲軸轉(zhuǎn)速傳感器、凸輪轉(zhuǎn)速傳感器、機油壓力、燃油溫度、增壓空氣溫度、燃氣溫度、燃氣壓力、調(diào)速器執(zhí)行器油門位置等數(shù)據(jù)采集，形成覆蓋發(fā)動機全工況的MAP圖，實現(xiàn)了雙燃料模式與燃油模式的自由切換及雙燃料發(fā)動機的穩(wěn)定運行。
從燃氣進氣管路到燃氣噴射閥均采用雙壁管結(jié)構?！げ捎煤侠淼目刂七壿?，可實現(xiàn)雙燃料發(fā)動機模式的自動轉(zhuǎn)換，保證在缺少燃氣情況下可用純柴油模式滿負荷運行。防爆門安裝在中冷后接管上，正對增壓空氣穩(wěn)壓腔，它能夠快速釋放燃氣回火爆燃能量，從而起到保護發(fā)動機進氣系統(tǒng)免遭損壞的作用。
