高压直喷天然气发动机（HPDI发动机）具有动力强、排放低优点
高压直喷天然气发动机，也称hpdi发动机，以天然气为主要燃料，向气缸内喷入柴油引燃，天然气以一定压力喷入火焰中进行燃烧释放能量，具有动力强劲、排放降低等优点。

油气混动！燃气可以取代柴油了？HPDI技术是什么鬼？_腾讯新闻
2023年9月13日 · 根据卡车之家百科记载：“HPDI发动机保持了与原柴油机相同的功率和扭矩（WP12HPDI蓝擎发动机的额定功率为480hp/2100rpm,最大扭矩为1970N.m/1200-1500rpm），其动力性与柴油机完全相同，比火花塞点燃式燃气发动机功率和扭矩提高20%。 而它的工作模式也很好理解，基本上就是在压缩上止点前用5%的柴油喷入气缸引燃，95%的天然气以300bar的压力喷入到火焰中成为主燃料燃烧做功。 而它在保障动力的同时，还能做到颗粒物质排放降 …

HPDI with pilot ignition is a commercially available technology originally developed for heavy-duty natural gas engines. Fuel injection relies on late (close to top dead center) cycle direct injection of gaseous fuel (in this case hydrogen) at moderate pressure (~300 bar).
HPDI LNG - Cespira
HPDI consists of a fully integrated on engine and off engine fuel system components and electronic control solution, with a cryogenic tank and integral high pressure liquefied natural gas (“LNG”) pump mounted on the chassis of the truck and plumbed to the engine where fuel pressure is regulated before being supplied to the injectors via ...
