A single cylinder engine includes an engine body having a combustion chamber, an intake opening and an exhaust opening which face toward the combustion chamber, an intake passage in communication with the combustion chamber through the intake opening, and an exhaust passage in communication with the combustion chamber through the exhaust opening, an intake valve that opens and closes the intake opening, an exhaust valve that opens and closes the exhaust opening, an injector that injects a fuel toward the intake opening and into the intake passage, a ternary catalyst provided in the exhaust passage, and an engine control unit (ECU) that performs a decelerated operation to selectively execute a cycle for injection of a fuel from the injector, a quantity of which makes an air-fuel ratio in the combustion chamber substantially equal to a theoretical air fuel ratio, and a cycle for inhibition of fuel injection from the injector.
