Scavenging a cylinder of an engine with fuel-free fresh air and injection with atomized liquid fuel by a pressurized gas are accomplished independently, at specific moments during by the operating cycle of the engine. The fuel is atomized and injected into the cylinder by gases tapped from cylinder of the engine. The injection device can comprise a reservoir in which the gases tapped from cylinder are stored. The gases can be tapped from cylinder by a pneumatic injector when the valve opens.
