The Extension of Opportunities of Dual Fuel Diesel-Hydrogen Engine by Usage of Hydrotreated Vegetable Oil (HVO) Instead of Regular Diesel Fuel
Original language description
The energy share of hydrogen in dual fuel compression ignition engine is limited by the low chemical efficiency of combustion at low loads. Unfortunately, low loads are typical operation modes of engines of passenger cars, therefore improving the parameters of low loads highlight the effects of dual fuel operation. Hydrotreated vegetable oil (HVO) has better ignitibility at cold conditions, higher cetane number than conventional diesel oil, and it does not contain any aromatics. These parameters lead to higher possible energy share of hydrogen at low loads, while the chemical efficiency of combustion is not worsened in comparison with regular diesel fuel. Another benefit of HVO-hydrogen dual fuel operation is the decrease of emissions of CO, unburned hydrocarbons and particles. Well to wheel emissions of CO2 is reduced by the production of both HVO and hydrogen from renewable sources. Combination of both fuels reduces the tailpipe emissions of CO2 from combustion engines to levels below the future requirements of regulations.
