As the country that emits most carbon in world, China needs significant and urgent changes emission control transportation sector order to achieve goals of reaching peak emissions before 2030 achieving neutrality by 2060. Therefore, promotion new energy vehicles has become key factor these two objectives. For reason comprehensive cost directly affects end customer’s choice heavy truck models, this work compares advantages, disadvantages, economic feasibility diesel, liquefied natural gas (LNG), electric, hydrogen, methanol trucks from a total life cycle end-user perspective under various scenarios. The study results show when prices LNG, electricity, fuels are at their highest, price hydrogen is 35 CNY/kg, five types highest lowest (HHT), (MHT), diesel (DHT), electric (EHT), LNG (LNGHT), ignoring adverse effects cold environments on car batteries. When average or levels, 30 CNY/kg 25 HHT, DHT, MHT, EHT, LNGHT. considering impact environments, even with lower electricity prices, EHT struggle be economical low. If above 1 CNY/kWh, regardless viability than HHT purchase 500,000 CNY CNY/kg. Simultaneously, an exhaustive competitiveness analysis powered diverse sources highlights specific categories ought prioritized for development during periods challenges they confront. Finally, based future trends, corresponding policy recommendations proposed facilitate high decarbonization sector.

However, methanol is low cetane fuel, creating challenges achieving stable operation, particularly at load. One potential solution through surface via glow plug. In this work, experiments were conducted on methanol-fueled 2.1 L single cylinder engine instrumented with The was designed alcohol combustion an elevated ratio (26:1) narrow injector umbrella angle (120 degrees) compared to standard diesel hardware. As such, no plume directly intercepted by the A representative load case of two conventional mixing controlled (MCCI) strategies (single injection pilot-main) three kinetically advanced CI (homogenous charge ignition, split injection, partially premixed combustion) tested without plug active. It found that had significant impact either MCCI strategy because strategies, phasing several degrees, due apparent combination heating small amounts exothermic reactions from fuel located near during stroke. When heavily stratified, it hypothesized flames could propagate start advance substantially. significantly decreased stability cyclic variability local conditions resulted high flame propagation subsequent autoignition charge.

The study involves retrofitting an original 6-cylinder 7.15L CI diesel engine with port injection (PFI) methanol enable DF operation. Later, injectors were replaced six plugs allowing SI Notably, efforts made minimize adaptations existing engine, maintaining compression ratio (CR) at 17.6:1 retaining same turbocharging pressure. This research aims assess feasibility conventional HD engines (high CR, large bore) for dual-fuel on methanol, a focus optimizing performance, while preserving key characteristics applications, e.g. high torque power density.
