"HFI is a bolt-on, aftermarket part that injects small amounts of hydrogen into the engine air intake, said Canadian Hydrogen Energy's Steve Gilchrist. Fuel efficiency and horsepower are improved because hydrogen burns faster and hotter than diesel, dramatically boosting combustion efficiency.



"HFI's manufacturer guarantees 10 percent fuel savings . . . Trucks with the HFI system produce half the amount of particulates -- microscopic, unburned bits of diesel. The system also reduces nitrogen-oxide emissions, which are major contributors to harmful air pollution, by up to 14 percent . . .


"The HFI units are relatively small and cost between $4,000 and $14,000, depending on the size of the vehicle."
