Automobiles

Abstract

An automobile includes an engine having a catalyst device incorporating a catalyst for reducing exhaust gas in an exhaust system and having an in-cylinder injection valve, an automatic transmission for shifting power from the engine and outputting the power to a drive wheel side, and a control device for performing catalyst warm-up control for warming up the catalyst by performing multi-stage injection for performing a plurality of fuel injections from the in-cylinder injection valve and a retard angle of an ignition timing. The control device executes the load factor increase control so that the required load factor to the engine becomes equal to or higher than the multi-stage injection realization load factor capable of realizing the multi-stage injection during the catalyst warm-up control.
