Hybrid vehicle and method in which the engine is preheated before start

   
   

An engine of a hybrid vehicle that is to be preheated before being started is connected to a heat accumulator that stores a portion of a cooling water that is kept warmed. During cold start of the vehicle, when a temperature of the cooling water in the heat accumulator is equal to or higher than a temperature of the cooling water in the engine by a preset amount, the cooling water kept warmed in the heat accumulator is fed into the engine. The motor is driven to operate the vehicle until the engine is sufficiently preheated.

Un motor de un vehículo híbrido que deba ser precalentado antes de ser comenzado está conectado con un acumulador del calor que almacene una porción de un agua que se refresca que se mantenga calentada. Durante el arranque en frio del vehículo, cuando una temperatura del agua que se refresca en el acumulador del calor es igual a o más arriba que una temperatura del agua que se refrescaba en el motor por preestableció cantidad, el agua que se refresca mantenida calentada el acumulador del calor se alimenta en el motor. El motor se conduce para funcionar el vehículo hasta que el motor está precalentado suficientemente.
