An engine having improved volumetric efficiency may include a cylinder, an intake valve, a piston, an exhaust valve and a crankshaft. The cylinder may include a cylinder bore. The intake valve may be configured to introduce a fuel and an air into the cylinder bore. The piston may be slidably arranged in the cylinder bore. The piston may be configured to convert an explosive power of an exhaust gas, which may be generated by combusting the fuel, into a linear driving force. The exhaust valve may be configured to exhaust the exhaust gas from the cylinder bore. The crankshaft may be connected with the piston to convert the linear driving force into a rotary driving force. The intake valve and the exhaust valve may be simultaneously opened within a rotation angle of about 3 to about 12 of the crankshaft.

An engine device including: an intake manifold (67) configured to supply air into a cylinder (77); a gas injector (98) configured to mix fuel gas with air supplied from the intake manifold (67), and supply mixed gas to the cylinder (77); an igniter (79) configured to ignite, in the cylinder (77), premixed fuel obtained by pre-mixing the fuel gas with the air; and a control unit (73) configured to execute a combustion control of a premixed fuel based on the output signal indicative of an output from the engine device. When the air amount is determined to be insufficient and when the output signal is lost, the control unit (73) estimates an output signal based on the fuel gas injection amount from the gas injector (98), and executes the combustion control based on the estimated output signal.
