Abstract
An engine and a method of controlling the engine may include an EGR injector provided such that EGR gas sprays that are injected toward a side wall of a combustion chamber reach the side wall of a combustion chamber, simultaneously; an EGR pipe connecting the EGR injector to an exhaust system of the engine and ejecting exhaust gas from the exhaust system; an EGR pump mounted in the EGR pipe and pumping the exhaust gas in the EGR pipe to supply the exhaust gas to the EGR injector; and controller connected to the EGR pump and the EGR injector and configured for controlling the EGR pump and the EGR injector so that the EGR injector injects EGR gas into the combustion chamber.
Claims20
An engine comprising:
- an exhaust gas recirculation (EGR) injector connected to a combustion chamber of the engine to inject EGR gas into the combustion chamber of the engine;
- an EGR pipe connecting the EGR injector to an exhaust system of the engine and ejecting exhaust gas from the exhaust system;
- an EGR pump mounted in the EGR pipe and pumping the exhaust gas in the EGR pipe to supply the exhaust gas to the EGR injector;
- and
- a controller connected to the EGR pump and the EGR injector and configured for controlling the EGR pump and the EGR injector so that the EGR injector injects the EGR gas into the combustion chamber.
