1. A split cycle internal combustion engine comprising:
a compression cylinder accommodating a compression piston;
a combustion cylinder accommodating a combustion piston;
a recuperator arranged to exchange heat between exhaust fluid from the combustion cylinder and working fluid being supplied from the compression cylinder to the combustion cylinder via a crossover passage; and
a controller configured to control operation of the engine based on an indication of a temperature of at least one of (i) a material of the recuperator and (ii) the working fluid in the crossover passage;
wherein controlling operation of the engine based on the indication of the temperature comprises: in the event that the indicated temperature exceeds an upper threshold value, controlling operation of the engine to reduce a temperature of the recuperator to reduce an amount of heat-induced damage inflicted on the recuperator.
