摘要： In a general-purpose engine having a throttle valve installed in an air intake passage connected to a combustion chamber, sucked air mixing with fuel to generate an air-fuel mixture to be ignited to drive a piston to rotate a crankshaft connected to a load, a first warm-up time period during which the engine is warmed up and a second warm-up time period which is longer than the first time period are determined based on detected engine temperature and a fuel quantity is increased during the first time period. The operation of the motor is controlled such that a change rate of throttle valve opening is limited within a range until the measured time exceeds the second warm-up time period after it exceeded the first time period. With this, it becomes possible to complete warm-up operation in a short period of time, while improving rate of fuel consumption and emission performance.

摘要： In a single-cylinder 4-cycle engine including an oxygen concentration sensor provided at a location upstream of an exhaust emission control catalyst, the influence of pulsation of the exhaust gas is eliminated to enhance the detection accuracy by detecting of the concentration of oxygen in the exhaust gas. A first pulse generator generates a pair of pulse signals a and b per one rotation of a crankshaft, and a second pulse generator generates pulse signals c and d at every very small angle of rotation of the crankshaft. The angular speed of the crankshaft is detected from the interval of the pulse signals c and d. The pulse signal output a when the angular speed is smaller is determined as being the output during a compression stroke, and is used as an ignition signal a1. The pulse signal output a when the angular speed is larger is determined as being the output during an exhaust stroke, and is used as an oxygen concentration detecting signal a2.

摘要： A thermal demand priority type cogeneration system, is made operative for obtaining power output without thermal demand. When the temperature in a hot water tank 17 is low, a heat request is output from a heat request generator 42 and thereby an engine 11 is driven. When the temperature T higher than a predetermined temperature T1, a first water supply instructing unit 44 opens a valve 39 and supplies water to the tank 17 to decrease the water temperature T. When the water temperature goes down, thermal demand is generated, the engine 11 is driven according to the heat request. So as to generate thermal demand, a discharge valve 41 may be opened when the water temperature T is at the predetermined temperature or higher. A second water supply instructing unit 46 opens the valve 39 when reserved water level in the tank 17 goes down. When the valve 39 is opened, water is supplied and the water temperature goes down and thermal demand is generated. At a power failure of a commercial electric power system 14, thermal demand is generated forcibly.
