  "textContent": "The method involve supplying liquid fuel into combustion chambers of an internal combustion engine (1), and precompressing combustion air over a charging device in a boost pressure spacer (8). Alternative-fuel is supplied to the spacer over a supply device in dual fuel operation. Exhaust gases of the engine are returned to the spacer over an exhaust gas reconducting valve (22). The engine is operated with increased exhaust gas reconducting rate in dual fuel operation, and air supply to the spacer is throttled such that lambda value of the exhaust gas is adjusted to 1.03 to 1.1. An independent claim is also included for an internal combustion engine.",
