Problem Statement
- The Transportation sector’s reliance on petroleum-based fuels contributes to poor air quality.
- Compression Ignition (CI) engines aim to use cleaner, renewable fuels like natural gas, propane, methanol, hydrogen, reformulated gasoline, and biodiesel.
- Biodiesel is a promising renewable fuel for automotive engines due to its low greenhouse gas emissions, complete combustion, and energy density.
- However, its effective utilization in diesel engines is limited due to its poor physical properties, which affect fuel-air mixture preparation and homogeneity.
- There is a need for suitable fuel vaporization technique that is economical, operates with less energy input and compatible with high viscous, low volatile biodiesel fuels.
Technology
Key Features / Value Proposition
Efficiency
- Uses flash heating of the high viscous fuel thereby increasing the efficiency of fuel-air mixing process and spray characteristics.
Compatible of fuels
- Heated tip injector of the present invention is compatible with for all 15 types of liquid fuels.
Retrofittable
- electromagnetic fuel injector fitted with cartridge heater (123) is retrofittable to the existing commercial-off-the-shelf direct fuel injector.
Controlling of temperature
- the temperature of the said cartridge heater (123) is controlled by means of an external circuit to avoid excessive heating.
Maintaining of fuel supply
- the fuel supply is maintained at a constant volume based on the capacity of the said carved fuel passage (127) and the duration of the nozzle
- lift deciding the amount of fuel being injected into the fuel injection system.
- appropriate for vapour injection avoiding restricted fuel supply
- cartridge heater (123) is positioned not to interfere with the electromagnetic solenoid actuation system
Viscosity Properties
- fuel inside the said carved fuel passage (127) results in lower viscosity thereby enabling homogeneous charge preparation with least input of electrical energy
plunger (124)
- electromagnetic solenoid plunger.
cartridge heater shape
- spindle shape
