Direct injection (DI) is widely recognised as "next generation"
technology that substantially boosts the efficiency of conventional
internal combustion gasoline engines. It involves injecting the
fuel directly into the cylinder (combustion chamber) of an engine,
instead of indirectly through an inlet port in a 4-stroke as would
be the case in a port fuel injection (PFI) or carburetor engine.
Orbital's core technology is a unique air-assisted
low-pressure direct fuel injection, combustion and engine management
system collectively called Orbital Combustion Process (or OCP™)
technology. The Orbital DI system creates a precisely-controlled,
finely atomised fuel cloud allowing engines to run with greater
fuel efficiently and with reduced emissions output.
Technology Highlights:
- Applicable to 4-stroke and 2-stroke engines
- In production on engines as small as 50cc
and as large as 500cc per cylinder
- Fuel economy improvement and reduction in
emissions
- Proven capability
