Hybrid Natural Gas (NG) Vehicles

Project Manager: Dr. Edgar Matida Lead Engineers: Drs. Xiao Huang, Junjie Gu and Jurek Sasiadek

Natural Gas

• Composition: mainly methane (CH4 - highest H/C ratio
• f all fuels), with other hydrocarbons (for example:

ethane, propane, butanes, and pentanes), carbon dioxide, nitrogen and hydrogen sulfide (H2S)

• Marketable natural gas (processed natural gas with no

impurities)

• Compressed natural gas (CNG)
• Liquefied natural gas (LNG)
• Liquefied petroleum gas (LPG; propane or butane)

Natural Gas Prices in Canada

Compressed Natural Gas (CNG) Powered Vehicles

• Properly tuned engines (either diesel or gasoline

engines) can be modified to burn compressed natural gas (CNG)

– Conversion – Additional tank (3600 psi) – Home fuelling compression stations (8 hours)

Hybrid CNG Vehicles

• Alternatives to conventional engines

– Natural gas fuel cells – Microturbines

• Addition of batteries and electrical motors to the

system

Goals

• Design, manufacturing, and testing of key subcomponents such

as engines, ignition and control system

• Emission measurements
• Natural gas fueling and storage
• Build and test a fully functional natural gas and battery/fuel cell

powered car

• Subjects involved: fluid mechanics, heat transfer, combustion

and emissions, structural analysis, and safety analysis

Project’s First Year Accomplishments

• Project started with converting a small engine/machine

to an alternative fuel source.

• Gave experience working on small engines and

knowledge of possible issues when working with larger

• nes.

Converting A Car to run off of CNG

• We have a vehicle to convert!
• Involves many exciting and new challenges.
• Requires design, manufacturing, installation and

testing.

• Building a Dynamometer to test a second engine that

we possess.

Different Projects under NGV

• Dynamometer and Engine.
• Fuel Injection and Emissions.
• Fuel Cells.
• CNG Tank.
• Home Refuelling.
• Advanced Design.
