Vehicle with IC engine, transmission and heat store

摘要

The vehicle has an IC engine and at least one transmission. It has a heat carrier circuit (1) passing through the engine (4) and a heat store (3). The heat carrier circuit may run, or be able to be switched, through a heat exchanger (5) for the lubricating oil of the transmission. The engine and the transmission oil heat exchanger may be in series or in parallel in the heat carrier circuit. There may be locking valves (7) in the branches (1a,1b) of the heat carrier circuit leading to the engine and to the heat exchanger. The heat carrier circuit may have an independently driven feed device.
