Abstract
An engine configuration for a motor vehicle is provided that has an internal combustion engine having direct fuel injection, which is thermally coupled to a cooling circuit to dissipate waste heat occurring in operation, and having a storage unit, which can be coupled to the cooling circuit, for storing thermal energy, which is implemented for the purpose of discharging store thermal energy to the cooling circuit and/or to the engine before the engine is put into operation and/or during a warm-up phase thereof.
Claims14
An engine configuration for a motor vehicle, comprising:
- a cooling circuit configured to dissipate waste heat occurring in operation;
- an internal combustion engine having direct fuel injection that is thermally coupled to the cooling circuit;
- and
- a storage unit coupled to the cooling circuit and configured to store thermal energy and implemented to discharge the thermal energy, which is stored before the internal combustion engine is put into operation.
A method for heating up an internal combustion engine, comprising:
- storing thermal energy in a storage unit coupled with a cooling circuit of the internal combustion engine;
- and
- transferring thermal energy stored in the storage unit to the cooling circuit before the internal combustion engine is put into operation.
