摘要： A direct injection engine capable of direct injection of fuel into a combustion chamber characterized in that discharge of gas containing hazardous gas component such as HC can be reduced and fuel economy can be improved by stratified charge combustion in the operation range of low to high speeds. Spray fuel from the fuel injector is fed to the ignition plug by tumble air flow generated in the combustion chamber and formed between the fuel injector located on the side of the combustion chamber and the ignition plug installed on the top of the combustion chamber. This engine (a tumble guide direct injection engine) is configured to ensure that fuel reaches the ignition plug at the time of its ignition.
